The purpose of a load test is to prove that the expected volume of a system can handle with a minimum acceptable performance drop. If a load test reaches a peak in the number of simultaneous users, the basic load will continue to increase the load in the system until the resources are overloaded. This pushes the system into a possible failure state to see how the system handles itself and whether the system can perform a proper recovery.
To summarize in short items;
- The load test tests the reliability and performance of the system.
- The Load Test helps identify bottlenecks in the system under severe user stress scenarios before they take place in the production environment.
- The load test provides excellent protection against underperformance and provides complementary strategies for performance management and production environment monitoring.
There are many ways to perform a load test. Here are some examples for you to get an idea:
Manual Load Test: This is one of the strategies of carrying out the load test, but it does not produce reproducible results, provides measurable stress levels in an application, and is a process that is very difficult to coordinate.
Load Testing Tools Developed at Home: An organization that recognizes the importance of load testing can create its own tools for performing load tests.
Open Source Load Testing Tools: There are several load testing tools available free of charge as open source. They may not be as sophisticated as their paid colleagues, but they are the best choice if you have a limited budget.
Enterprise-Class Load Testing Tools: They usually offer the Capture / Playback option. They support a large number of protocols. They can simulate an enormous number of users.
The load test allows you to foresee the variables listed below in case of abnormal use of your system.
- Response time for each process
- Performance of system components under various loads
- Performance of database components under different loads
- Network latency between client and server
- Software design issues
- Server configuration issues such as web server, application server, database server, etc.
- Hardware limitation issues such as CPU maximization, memory limitations, network congestion, etc.
Controlling security gaps in your systems by cyber security companies, reporting their strengths and weaknesses and presenting them to your information is of great importance for your system security.
Because despite all your attention and efforts on security, you and your employees have no clue to the methods and tools that attackers can use to exploit the system. Depending on the level of knowledge and experience of the attacker, probabilities and risks change dimension.
For this reason, it is a more realistic and productive step to ensure security and increase the security of your “White Hat” teams that can think and act like a hacker and take precautions against these methods by knowing the attack methods.In addition, standards such as PCI, HIPAA, GDPR require Pentest (penetration testing).
In order for the penetration test to achieve its purpose and provide efficiency, the steps to be applied under the headings “pre-test”, “during test” and “post-test” should be determined in a plan.
Here are a few questions that can help you shape your Penetration Testing Project Plan:
- What is the scope of the penetration test? (Black Box, White Box, Gray Box)
- Should my risky systems be included in the penetration test?
- How often should I perform the penetration test?
- From which company should I get the penetration test service?
It is much more important to evaluate the results of the penetration test and to take the relevant actions. We must regret that the common misconception; examining the report by simply having an penetration test and resolving only very urgent weaknesses and postponing others. As a result of not resolving these vulnerabilities, it is often the case that the same vulnerabilities are re-detected in the next penetration test.
In order to achieve the purpose of the test, we share some important items with you that are recommended to be applied:
- The penetration test report should be shared with the senior management to provide the necessary management support.
- It is recommended that penetration test results be presented as a risk map to management.
- The test report should be examined in detail and the workload for resolving those vulnerabilities should be appropriately distributed to the relevant personnel.
- It is recommended that the penetration test report be shared with the software team and system administrators in a meeting. This is because the vulnerabilities found may be due to a frequently used algorithm or system management tool. In the future, it is aimed to gain the necessary point of view to the software team and system administrators in order to prevent weakness in these issues.
- Detailed monitoring of the process of resolving the vulnerabilities mentioned in the report should be performed.
- The date of the next penetration test should be determined.
Due to the large amount of data stored in web applications and the increase in the number of transactions on the web, the Security Testing of Web Applications is very important day by day. If your applications on the web cause any security vulnerability, attackers can exploit this vulnerability to damage your systems. However, within the Web Application Penetration Testing, security experts can detect security weaknesses in your systems before the attackers and report them to you.
Web application infiltration tests are performed on a classification. Because, the importance of tests varies according to the systems. For example, it is recommended that a company or organization that has critical attack potential should have their tests tested once a week. Those with moderate likelihood of attack should take the test once every 6 months and those who are normal should take it once a year.
After the Web Application Penetration test, security experts who prepare the test will prepare a detailed report. Institutions or companies that have taken the test should examine the test reports in detail and close the vulnerabilities and secure their systems.
The VoIP (Voice Over Internet Protocol) infrastructure, which enables internal units to communicate with each other within your systems, is a system that does not have sufficient protection against external and internal attacks. There are vulnerabilities that allow complex attacks such as call tracking, call management, phone calls and even unauthorized recording of calls.
At the end of the VoIP Infrastructure Penetration Test, which will be carried out by our team of experts with high level technical knowledge, you will;
- Understand the VoIP configurations and network designs in general terms,
- Conduct studies on security vulnerabilities determined by our team,
- Witness the risks of VoIP infrastructure in your system to be minimized.
Attacks on the VoIP infrastructure:
- SIP Attacks
- SIP Record Missing
- Online Spam
- Embedding Malware
- Web Attacks
- Viproy (VoIP penetration test kit)
- -svmap -svwar -svcrack -svreport
- VoLTE Attacks
- Sniffing VoLTE interfaces
- Open Keys on GSM SIM
- User Location manipulation
- Manipulation of Circulation Information
- Side Channel Attack
SiGploit (Telecom Signal Exploitation Framework)
The most used protocols in VoIP infrastructure:
H.323: H.323 is data on the IP standard provided by the International Telecommunications Union Standardization Sector (ITU-T). As you can see, this standardization agency uses some letters to describe the scope based on the many criteria listed here:
H: For audiovisual and multimedia systems
G: For transmission systems and media
Q: For switching and signaling
T: For terminals for telematics services
H.323 is one of the oldest packet-based communication systems protocols. Thus, this protocol is stable. Current version v6. Cisco call manager is used by many vendors in many products such as NetMeeting and RadVision.H.323.
Skinny Client Control Protocol: The Skinny Call Control Protocol (SCCP) developed by Selsius is a Cisco-specific protocol. This dialog uses the following different message types:
RTP / RTCP: Real Time Protocol (RTP) is a transport protocol based on RFC 3550, especially over UDP.
Secure Real Time Transfer Protocol (SRTP): Secure Real Time Transfer Protocol (SRTP) is an application protocol based on RFC3711. SRTP offers advanced security features; Thus, it secures RTP through encryption with a keystream using the XOR process.
H.248 and Media Gateway Control Protocol: Media Gateway Control Protocol (MGCP) is a protocol developed by Cisco.
Session Initiation Protocol (SIP): Session Initiation Protocol (SIP) is a session management protocol based on the RFC 3261 protocol.
SCADA systems have switched from closed networks to open source solutions and TCP / IP enabled networks. This has caused security vulnerabilities. Not only can the data be damaged, but the control of the facilities can lead to production degradation, which can lead to physical damage and risks. Live systems are tested for effective management and mitigation of this risk. Damages on the site are detected or the areas where damage is foreseen.
With the tests performed by our experts, we offer you the opportunity to better understand security measures and weaknesses and prepare for future attacks.
We offer a professionally developed plan to prevent hazards and high-cost damage from security breaches and improve your security measures.
An SCADA system is a common industrial process automation system used to collect data from devices and sensors in remote sites and to transmit data from a central site for monitoring or control purposes.
SCADA is used in power generation plants (Nuclear, Hydroelectric), power lines, flow measuring equipment in pipelines, natural gas production and processing plants, and many factory systems.
Here are some examples of tools used in the SCADA Penetration Test:
- Network Security Toolkit
- nmap Scripts
They often include more people, resources and time to fully understand the realistic levels of risk and vulnerability to an organization’s technology, people, and physical assets.
RedTeam Pentesting is generally used by organizations with more mature or improved security postures. After performing a penetration test and identifying most vulnerabilities, physical tests are performed to access sensitive information and violate defenses. To obtain data, it extends from shuffling garbage in front of the institution building to physically entering the Data Center of the organization concerned.
With the RedTeam Penetration Test, you will have the opportunity to thoroughly examine the security of your organization in every aspect.
RedTeam Penetration testing begins with exploration to gather as much information as possible about the goal of acquiring knowledge about people, technology and the environment to create and obtain the right tools for participation. Using the Open Source Intelligence Gathering, RedTeam can gain a deeper understanding of infrastructure, facilities, and employees to better understand their goals and operations. This also allows for armament, such as creating custom malicious file loads, preparing RFID clones, configuring hardware trojans, or creating fraudulent individuals and companies.
As part of the test, RedTeam teams take actions, such as face-to-face social engineering or hardware trojan horses, indicating that there is no opportunity for exploitation. The next step is to take advantage of these weaknesses and bypass physical checks to jeopardize servers, applications, and networks, or prepare to upgrade authority.
During the installation phase, Red teams make use of the exploitation step to create a secure area. Presumably, they endeavor to gain command and control through compromised servers or malicious file uploads or through all this operation by using physical key notifications and locking selected doors. When remote access to exploited systems is stable and reliable, the stage for actual targeted actions, such as the consumption of critically sensitive data, information or physical assets, is determined.
Our team having experience and knowledge on many different issues such as the ability to copy ID cards of your corporate employees using the Blackbox method, the availability of leaked information of your organization not only on the Internet, but also on the Deep and Dark Web, the general profile and interests of your corporate employees, the likelihood and vectors of phishing attacks against their employees, the attention and awareness of the entrance security staff your employees’ awareness of information security, the impact of malicious hardware to be coded on your systems, will guide you through real-life scenarios to determine not only how secure and stable your information systems are, but also how secure your organization is in every aspect.
Nowadays, mobile applications are increasingly used in all areas, making them increasingly interesting for malicious attackers. Therefore, mobile applications need to have a strong security, just like websites. Because if your applications on the mobile application cause any security vulnerability, attackers can exploit this vulnerability and damage your systems. However, within your Mobile Application Penetration Testing, security experts can find security weaknesses in your systems before the attackers and report them to you.
Testing mobile applications is usually done after updates. Because the developers have made a change or correction on the application. Therefore, there is a high probability of security weakness in practice. In addition, it is recommended that the Mobile application infiltration test is performed regularly every 6 months.
After the Mobile Application penetration test, the security experts performing the test prepare a detailed report. In the content of this report, information about the services available in your systems, weaknesses found and the solution suggestion following these issues are presented.
The most fragile link in the security chain is the human factor. The reason for the success of the hacking attack that has brought many sounds from the past to the present day is that the employees of the institution or organization do not have sufficient security awareness. Mail Gateway security testing is one of the most important tests next to the technical protection you provide to your assets in order to raise awareness of your organization.
As technology evolves and defensive measures increase, attackers seek new ways without wasting time. Attack methods continue to evolve with each passing day and are supported by new methods. You can create the fastest awareness of the attack methods that are updated with the Mail Gateway Security Test which will be done 3 times a year.
Mail Gateway Security Test; protection against malicious URLs, protection against impersonation attacks, and protection against malware.
Regardless of how much or less attention is paid to setting up your wireless network, businesses need to proactively investigate security vulnerabilities to prevent unauthorized access to network resources and data leakage. Because if your applications on the Wireless Network cause any security vulnerability, attackers can exploit this vulnerability and damage your systems. However, within the Wireless Network Penetration Test, security experts can detect security weaknesses in your systems before the attackers and report them to you.
If there is a security vulnerability in your Wireless Network, attackers can exploit this vulnerability and seize your systems. Therefore, it is recommended that your Wireless Network test be performed regularly every 6 months.
After the Wireless Network penetration test, the security experts who conduct the test will prepare a detailed report. The test institutions or companies should examine the test reports in detail and close the weaknesses and secure their systems.
The risk of your growing technical infrastructure being the target of the attackers increases with your corporate development. In order to strengthen your defenses in the face of these incredible attacks, you should take DoS / DDoS tests once a year.
DDoS/DoS attacks are known as the fearful dream of commercial platforms and the size of these attacks is increasing day by day. DDos/DoS Tests are required to minimize financial loss against possible attacks and simulate the moment of crisis.
As a result of DDoS / DoS Tests, which are performed with the aim of overloading and disabling the system with simultaneous attacks from one or many different IP addresses, the behavior of your system against these attacks is analyzed and proactive solutions are produced by our expert team.
Controlling security gaps in your systems by cyber security companies and reporting their strengths and weaknesses to your information is of great importance for your system security.
Because despite all your attention and efforts on security, you and your employees have no clue to the methods and tools that attackers can use to exploit the system. Possibilities and risks vary according to the attacker’s level of knowledge and experience.
For this reason, it is a more realistic and productive step to provide security and increase security for your “White Hat” hacker teams who can think and act as a hacker and take precautions against these methods by knowing the attack methods.
In addition, standards such as PCI, HIPAA, GDPR require Pentest (penetration testing).
Attackers or malicious individuals may use known methods on the respective software and hardware equipment to exploit or exploit the software and hardware used within your systems, or use zeroday vulnerabilities. So instead of using known vulnerabilities, they can discover and exploit a new one.
In addition; that your systems have the most up-to-date technology level does not necessarily mean they are properly configured. While the people who install your systems do their work by aiming for the correct operation of the system, we do our work by aiming to protect your systems.
When Infinitum IT performs external network penetration testing, we try to exploit vulnerabilities identified in networks, systems and services to access sensitive information using the appropriate tools available. We test under controlled conditions to minimize the risk of downtime. Our aim is to provide comprehensive details of the security weaknesses that exist around you.
Infinitum IT’s approach to external network penetration testing is summarized as follows:
Finding target hosts and services, evaluating the security of these targets with penetration test tools and methods, trying to gain access to target hosts and having higher powers within the system.
Our detailed methodology includes the following steps:
- Reconnaissance: Initial discovery activities to find responsive hosts and services in each public IP range and facilitate the development of the target list.
- Target Planning: The first targets are selected according to the opportunity obtained and prioritization is made for the attacks in the first stage.
- Vulnerability Ranking: Both published and undocumented vulnerabilities are listed to identify possible exploits on each targeted host.
- Vulnerability Assessment: Additional tests are performed to validate vulnerabilities, eliminate false positives, and verify target selection.
- Attack Planning: Using the information collected; methods, tools and approaches are chosen to follow the services that are likely to offer an opportunity to gain access.
- Exploitation: Tests are performed on vulnerable hosts, applications, networks and services to provide command and control, ideally persistently.
- Privilege Escalation and Lateral Movement: Post-abuse operations are performed to gain additional access, penetrate the internal environment, upgrade privileges, release lateral hosts, and gather additional information.
- Data Detection: Accurate information, configuration information and other evidence that may have an impact on target systems is collected.
- Verify users with username and password.
- Ensure the Coding Policy by observing the Service Providers Policy.
- Strong password policy is recommended.
- Regularly change user account names on a per organization basis, such as a password assigned by cloud providers.
- Maintain information released during the Penetration Test.
- Password encryption is recommended.
- Use centralized Authentication or single sign-on for SaaS Applications.
- Ensure that the Security Protocols are up to date and flexible.
Cross-Site Request Forgery: CSRF is an attack designed to persuade a victim to submit a request to perform certain tasks as a user, which is inherently harmful.
Side Channel Attacks: This type of attack is cloud-specific and potentially very destructive, but largely requires skill and luck.
This form of attack attempts to violate the victim’s privacy indirectly through the use of shared resources in the cloud.Signature Wrapping Attacks: This is another type of attack, not cloud-specific, but dangerous for the security of a web application.
Basically, the signature wrap attack is based on the use of a technique used in web services.
- Hijacking using network sniffing
- Session hijacking using XSS attacks
- Domain Name System (DNS) attacks
- SQL injection attacks
- Cryptanalysis attacks
- Denial of service (DoS) and Distributed DoS attacks
Controlling security gaps in your systems by cyber security companies and reporting their strengths and weaknesses to your information is of great importance for your system security.
But the security of your company depends on the security of your cloud-based infrastructure as well as your systems. Our Cloud penetration testing service will help you determine how secure your assets in the cloud are.
The difference between the BRSA Compliant Penetration Test and other penetration tests in terms of test steps, methods and tools used is the scope of the test and the obligations of both the tester and the institutions having the test.For this reason, the methods and tools mentioned in our other Penetration Test articles on our website are examples of the methods and tools used in BRSA Compatible Penetration Tests.
As stated in the same communiqué, Minimum Penetration Test scope should include:
- Communication Infrastructure and Active Devices
- DNS Services
- Domain and User Computers
- E-mail Services
- Database Systems
- Web Applications
- Mobile Applications
- Wireless Network Systems
- ATM Systems
- Distributed Decommissioning Tests
- Code Analysis
- Social Engineering
- Intranet Security Checkup
Banking and finance sector has become the target of the biggest cyber attacks both in our country and worldwide.
Pursuant to the subparagraph (d) of the third communiqué of the Communiqué on the Principles of Information Systems Management in Banks dated 24.07.2012 and numbered B.02.1.BDK.0.77.00.00 / 010.06.02-1; The banks in our country are obliged to have an independent infiltration test performed once a year.
It is recommended that the APT Attack Simulation Service that you will take in order to keep your organization’s awareness alive and improve your measures will be carried out every six months.
The most dangerous players in the cyber world are the APT groups, which have financial or motivational support, patiently investigating their goals and weaknesses. With highly customized malware attacks, they can remain hidden for a long time, damaging the systems they can access. It is important to be able to analyze your behavior in the event of a possible APT attack.
It is within the scope of APT Attack Simulation to check for existing security mechanisms against APTs and to detect channels that may leak data.
Controlling security gaps in your systems by cyber security companies and reporting their strengths and weaknesses to your information is of great importance for your system security.Because despite all your attention and efforts on security, you and your employees have no clue to the methods and tools that attackers can use to exploit the system.

The software and tools used can be examined under two headlines: software and tools for automatic scanning and software and tools for manual scanning.
Software and Tools Providing Manual Scan:
- Burp Suite
- John the Ripper
Kali Linux distribution provides such open source penetration testing software and tools installed on the system.
Software and Tools for Automatic Scanning:
Penetration test types in general terms can be summarized as;
- Local Network Penetration Test
- External Network Penetration Test
- Web Application Penetration Testing
Local Network Penetration Testing: Studies are being carried out to find out if your internal network system is really secure and how far the intruders can reach the intrusion network.
External Network Penetration Testing: Studies are being conducted to find out if your external network system is really secure and how far the attackers who infiltrate your external network can reach the system.
Web Application Penetration Testing: Studies are being carried out to find out if your web applications are really secure and how far the attackers who infiltrate your web applications can reach the system.
Penetration test methods in general terms can be summarized as;
Blackbox: In the Blackbox test, the tester has no knowledge of the system and its internal functioning. The test is carried out to see what weaknesses a malicious person can use to infiltrate the relevant system for any reason, and what damage it may cause.
Greybox: In the graybox test, the tester has a partial knowledge of the system and its internal functioning. An attacker with limited knowledge of the system is tested to see what kind of damage it can cause.
Whitebox: In the Whitebox test, the tester has full knowledge of the system and the internal functioning of the system. In this method, a test is performed to see what kind of damage can be caused by the information of a person who is already working in your company or has worked before.
Although defensive security products are improving day by day, the number of hacking cases does not decrease at the same rate. Therefore, you should realize that the spotter applications you host on your system may not be sufficient and you should extend your domain control before it is too late. The detailed research and analysis of the information that the institutions / organizations possess and which will pose a danger in case of leakage has an important place among the current and visionary approaches of cyber security.
The 3W title covers three main environments: Deep Web, Dark Web and Clear Web. Using our experience in cyber intelligence, we conduct research on every important point on the web.
We agree that malicious hackers, termed black hats, do not have periodic or systematic attack schemes. Based on our research and information, we recommend that you get 3W analysis service once a year.

51% Attacks: 51% attacks are one of the most well-known blokchain security issues. In the 51% attack, one or more malicious entities control the majority of the hashrate of a blockchain. They can reverse the process to make double spending with the majority hashrate and to prevent other miners from approving the blocks.
In 2018, many important crypto currencies, such as ZenCash, Verge and Ethereum Classic, were attacked by 51%. In general, the attackers exploited this blockchain security problem and earned more than $ 20 million last year.
Stock Market Attacks: One of the most expensive block chain security issues is not a problem in the block chain technology itself. Crypto money exchanges have become a profitable area for hackers because of their huge crypto usage and sometimes weak security practices. Since many exchange platforms are centrally centralized, they restore the decentralized benefits of the blockchain.
Any early crypto buyer can tell you about the 2014 Mt Gox hack. Mt. Gox was the stock market leader of the time and managed almost 70 percent of all bitcoin transactions. In February 2014, the stock market revealed that a hacker stole around 850,000 BTC (~ $ 473 million) from the platform. The affected users were left behind.
Social Engineering: Another blockchain security issue that you and your employees should know is social engineering. Social engineering comes in many forms, but the goal is always the same: to obtain your private keys, login information or more directly in your crypto currency.
Phishing: Phishing is one of the most common forms of social engineering. In an attempt to fake, a malicious player sends you emails, sends messages, and even creates a website or social media account that mimics a company brand you trust. Typically, they will ask you to submit your credentials under a gift or a critical issue to enforce a sense of urgency. If you submit your information, there is very little you can do to prevent them from deleting your account.
IoT involves adding an internet connection to related computer devices, mechanical and digital machines, objects, animals and people. Each “thing” has a unique identifier and allows you to automatically transfer data over a network. Allowing devices to connect to the Internet can cause a number of serious security vulnerabilities if they are not properly protected.
IoT security has been the subject of review after a series of high-profile events using a common IoT device to infiltrate and attack a larger network. Implementing security measures is critical to securing networks with IoT devices connected to them.
Numerous challenges prevent the security of IoT devices and end-to-end security in the IoT environment. Because the idea of networking tools and other objects is relatively new, security is not always considered a top priority in the design phase of a product. In addition, since IoT is a developing market, many product designers and manufacturers are more interested in marketing their products rather than taking the necessary steps to ensure safety.
A major problem with IoT security is the use of hard-coded or default passwords that could lead to security breaches. Even if passwords are changed, they are not strong enough to prevent leakage. Many devices do not offer advanced security features. For example, sensors that monitor humidity or temperature cannot meet advanced encryption or other security measures. In addition, many IoT devices receive virtually no security updates or patches with the idea of “set and forget”.
From the manufacturer’s point of view, providing security from the very beginning can be expensive, slow down development, and cause the device to malfunction.
A series of attacks took place in various media, from refrigerators and TVs used to send spam, to hackers who infiltrated baby monitors and tried to talk to children. It should be noted that most IoT attacks do not target the devices themselves, but rather use IoT devices as the entry point to the network.
For example, in 2010, researchers found that the Stuxnet virus was used to physically damage centrifuges in Iran, with attacks starting in 2006 being the primary attack in 2009. Stuxnet virus, generally regarded as one of the oldest examples of IoT attack, uses malware to infect instructions sent by programmable logic controllers (PLCs) by targeting centralized control and data acquisition (SCADA) systems in industrial control systems (ICS).
In December 2013, Proofpoint Inc.’s corporate security company researcher discovered the first IoT botnet. According to the researcher, more than 25% of botnet consisted of non-computer devices such as smart TVs, baby monitors and home appliances.
In 2015, security researchers Charlie Miller and Chris Valasek wirelessly attacked a Jeep, changed the radio station in the car’s media center, switched on the windscreen wipers and air conditioning, and stopped the accelerator pedal to operate. They said they could kill the engine, activate the brakes, and completely deactivate the brakes. Miller and Valasek were able to infiltrate the vehicle’s network via Urys, Chrysler’s in-car connection system.
For businesses migrating to the cloud, a robust cloud security configuration is mandatory. Security threats are constantly evolving and becoming more complex, and the cloud system is no less risky than an on-premises environment. For this reason, it’s important to work with a best-in-class security provider that is customized for your infrastructure.
Cloud service providers use a combination of methods to protect your data.
Firewall (Firewalls) protects your network security and your end-users’ environment, traffic between different applications stored in the cloud.
NAC (Network Access Control) protects data by allowing you to set access lists for different entities. By providing strict access control, you can protect critical documents from malicious insider or hackers with stolen credentials.
Data Security methods include virtual private networks, encryption, or masking. Virtual private networks (VPNs) allow remote employees to connect to corporate networks.
Data Masking encrypts identifiable information such as names. This protects data integrity by keeping important information confidential.
Cyber Reconnaissance detects security threats and lists them in order of importance. This feature helps protect critical mission assets from threats.
Cloud-based security systems offer the following advantages:
- Protecting your business from threats
- Protection against internal threats
- Preventing data loss
The major threats to systems include Malware, Ransomware and DDoS.
Malware and Ransomware Violations: Many cloud data security solutions identify malware and ransomware. Firewalls, spam filters and identity management help with this. This keeps malicious email away from the employee’s inboxes.
DDoS Protection: In a DDoS or distributed denial of service attack, your system is full of requests. Your website will slow down until it crashes when the number of requests is too large to process. Cloud security services actively monitor the cloud system to identify and defend against attacks. They can take steps to secure your systems by alerting your cloud provider of the attack in real time.
We think that SIEM service is a must rather than a need, because the benefits of SIEM products allow an organization to see the big picture of security incidents throughout the organization. By combining security log data from enterprise security audits, host operating systems, applications, and other software components, SIEM can analyze large amounts of security log data to identify attacks and threats hidden within it. A SIEM can usually identify malicious activities that no other hostcan identify, because SIEM is the only security check with enterprise-wide visibility.
In some aspects, security information and event management (SIEM) are different from the normal, average event log management that businesses use to look at network vulnerability and performance. However, as a term that we can express various technologies together, SIEM is built on the basic principle of event log management and monitoring. The biggest difference may be related techniques and features.
The following are examples of software tools used in SIEM and Log Management:
- SolarWinds Security Event Manager
- ManageEngine EventLog Analyzer
- Micro Focus ArcSight ESM
- Splunk Enterprise Security
- LogRhythm Security Intelligence Platform
- AlienVault Unified Security Management
- RSA NetWitness
- IBM QRadar
Any event that is not handled and resolved correctly can result in larger problems that can result in malicious data breaches, large costs, or system crashes. Rapid response to an event will help an organization minimize losses, reduce exploited security vulnerabilities, restore services and processes, and reduce the risks posed by future events.
Event response allows an organization to be prepared for known as well as unknown, and is a reliable way to detect security events as soon as possible. In addition, event response allows an organization to create an implementation plan to stop an uninvited guest from damaging the system.
Organizations; systems, software and hardware tools, servers, etc. they may be exposed to different security incidents. What may be considered a serious event for one organization may not be critical to another.
Examples of security incidents that may adversely affect organizations include:
Distributed denial of service (DDoS) attack against critical cloud services.
A malware or ransomware infection that encrypts critical business files on the corporate network.
A successful phishing attempt that exposes customers’ personally identifiable information (PII).
What is missing is an unencrypted laptop that is known to have sensitive customer records.
The event response plan is a set of instructions that the event response team will follow when the event occurs. If properly developed, it should include procedures for detecting, responding, and limiting the effects of a security event.
When an event response plan is not implemented, an organization may not be able to detect the attack or, if a violation is detected, may not implement the appropriate protocol to address and eliminate the threat.
In general, an incident response plan has six main phases:
Preparation: Prepare users and IT staff to deal with potential incidents if they occur.
Definition: Determining the criteria for qualifying an event as a security event.
Limitation: Limiting damage and isolating affected systems to prevent further damage.
Eradication: Find the root cause of the event and remove the affected systems from the production environment.
Recovery: Allow affected systems to re-enter the production environment and ensure that there are no threats.
Lessons learned: Completing incident documents, analyzing to learn from the event, and potentially improving future response efforts.
One of the biggest problems that arise with the introduction of GDPR is consent and, in particular, the area of consent for marketing. Approval according to the GDPR must be freely given and clear.
Current legislation allows for approval with a “renounce” checkbox. However, the new regulation requires approval through a “selection”. Therefore, the data owner checks a box to agree to receive marketing materials. Organizations should review their databases for appropriate approval.
One of the problems with re-approval is the response rate to these requests, which may be historically low. Failure to respond to such requests means that consent has not been received and you will not be able to contact them again.
In practice, many organizations see the new regulation as an opportunity to “clean up” marketing databases and to ensure that the databases are targeted to those who are really interested in getting marketing information.
You might think that the data is deleted when you press the delete key on your computer. However, erasing digital data is not easy.
However, you can establish a data deletion policy with your IT department or your outsourced IT service provider, ensuring that the data to be deleted is kept in an archive with strict access restrictions, so that archived data cannot be directly accessed, so that it is considered dead data.
Yes, the camera images of the data owners are personal data under existing and new regulations.
If the data request is received and your organization still holds images of the data owner, you must provide them to the requesting party.
In practice, camera recordings are kept for a short time, normally 30 days; therefore, if the request is made after this time, you do not have to provide it.
Firewalls are often compared to a lock on your network door. However, it may be more accurate to say that a firewall is a door.
In the absence of a firewall, any connection can flow freely to your network. Including links from known malicious sources. This means that you may run the risk of unauthorized access to your networked files, which could lead to data breaches, malware infection, or worse.
Therefore, you need a firewall to filter most malicious connections.
Firewalls work by examining data packets (small pieces of data) according to an internal list of rules. The following are examples of these rules:
IP addresses: Filter traffic from suspicious IPs
Domain names: Block traffic from known malicious domains
Ports: Block traffic attempting to enter from a specific port
Content: Blocking data packets with specific keywords
A firewall scans the contents of the packet and then determines whether it will allow it according to existing rules. In a typical network setup, all connections to the Internet pass through the firewall. So it examines all incoming and outgoing packets.
The audit process involves comparing the contents of a package according to the rules of the firewall. It reacts differently to a match, depending on whether the rule is set to a black list or a white list.
A blacklist rule blocks packets that match criteria. The whitelist rule blocks packets that do not meet the criteria. The rules of a firewall are highly configurable. This means that you can make the package inspection process specific to your security installation. For example:
Create your own company’s IP address whitelist.
Prevent any stranger from accessing those behind the firewall.
Blacklisting the IP of a known malicious file server.
Prevent malware from distributing to your network.
Whitelisting for specific domain extensions (.com, .co.uk, .edu etc.) in outbound traffic. Prevent personnel from accessing potentially dangerous sites.
5 basic things your SOC will do:
- Proactive detection of malicious network and system activity. Instead of waiting an average of 206 days for companies to detect a violation, you want to be notified as soon as possible to minimize the impact of the violation.
- Threat Awareness allows you to reconfigure your defense configuration before the threat hits you.
- With Vulnerability Management, it allows you to see what might be compromised against new threats on your network.
- Thanks to the awareness of hardware and software assets running on your network; keep you informed of the types of threats to your assets.
- Log Management allows you and any authority to complete forensic information if you are exposed to a security incident or unauthorized access.
These are the main functions you want in your SOC, such as compatibility monitoring and others. It is indisputable that they are all critical functions to ensure the protection of your company.
Let’s face it, it’s expensive to build a SOC.
If you’re in a similar position with most IT professionals, you probably don’t have a big budget for security-related spending, and you can’t fight to convince top management to allocate enough funds to secure your corporate data.
Businesses seem to devote more than a percentage of their overall IT budgets for security than ever before. Regardless, most of us can probably show enough evidence that more than ever is not enough to secure your network.
Of course, your spending doesn’t end with creating a SOC.
In addition to the initial costs of building a SOC, operating and repairing from time to time, changing personnel, investing in new technology and so on. Make sure you have enough money for When preparing your budget to create SOC, you must ensure that your top management team provides financial support, taking into account the following three elements at a minimum.
Initial investment for SOC construction (construction costs, equipment, personnel)
Repeated costs in the operation of SOC (salaries, maintenance, public services, education)
Buffer for unexpected expenses (new technologies, replacement of personnel, repairs)
An NOC is a network processing center. While a NOC focuses primarily on minimizing downtime and meeting service level agreements, a SOC looks deeper into cyber security threats and vulnerabilities.
SIEM stands for Safety Information and Event Management. A SOC is a group of people and tools that work together, and SIEM is part of the application they need to follow.
When it comes to cyber security, businesses have to prepare for unexpected situations. This means that there is a solid plan to intervene. A security operations center team can ensure that problems are quickly found and resolved as soon as possible.
Information technology presents new and complex ethical, legal and other problems in society that result in reactions from both good and bad use of information and communication technologies. Therefore, information technology law, like other laws, is critical to protecting the rights of its users. This can be achieved through privacy, data protection, validity of online contracts, electronic procurement, data integrity and authenticity, identification of intellectual property rights (IPRs) and trust in open systems.
In the virtual world of our age, people will need information law in order to feel safe and to use their rights within the legal framework.
Crime against people: These crimes occur online and affect the lives of real people. Some of these crimes include cyber harassment and surveillance, the distribution of child pornography, various forms of fraud, credit card fraud, human trafficking, identity theft and online smear or slander.
Offense against property: Some online offenses are committed against properties such as computers or servers. Examples of these crimes include DDOS attacks, hacking, virus transfer, cyber and spelling url hijacking, computer attacks, copyright infringement, and IPR infringements.
Crime against government: When a cyber crime is committed against the government, it is considered an attack on the sovereignty of the country and an act of war. Cybercrime against the government includes hacking, access to confidential information, cyber warfare, cyber terrorism, and pirated software.
An important part of cyber law is intellectual property. Intellectual property may include fields such as inventions, literature, music and businesses. IP rights related to cyber laws are generally divided into the following categories:
- Trade Secrets
- Domain Disputes
- Data storage

Smartphones offer many different features and allow users to do almost anything they have done with computers before. Smartphones replace desktop computers in almost every aspect, with portability advantages; from private use to business, from taking photos to online banking.
As a result of this situation, smartphones carry valuable information for many researches. It helps the forensic researcher to identify the target person and access information such as recent chats, call records, location data, pictures, and information about their recent activities. In most cases, they carry more personal information than a traditional PC used. Thus, analyzing mobile phones has become the main part of a forensic investigation.
There are 4 main parts of a forensic investigation:
- Seizure: The responsible organization seizes the mobile device and protects it from network communication.
- Data Extraction: Data extraction from a mobile device with a known mobile forensic toolkit. (Cellebrite, UFED, MSAB XRY, Oxygen Extractor, Hancom GMD, etc.)
- Analysis: Analysis of data extracted with the aid of a mobile forensic toolkit. Evidence search and verification.
- Reporting: Exporting evidence that is easy to understand for later use of non-technical personnel.
Environmental documentation: When assessing evidence in any judicial institution, preparing documents as required is one of the most important tasks. First of all, photographs of the mobile device itself and the environment (especially cables, adapters, docking station, etc.) should be taken. Also note the status of the device (operating / not operating; locked / unlocked; visible damage, etc.) in the documentation.
IMEI documentation: As an identifier for smartphones, the documents usually use the IMEI (International Mobile Station Equipment ID). Because IMEI needs to identify a device in the cellular network, dual SIM phones have two IMEIs, and phones made for the CDMA network have MEIDs instead of IMEIs. Tablets that are not capable of binding to a cellular network do not have an assigned IMEI.
Usually the IMEI is printed on the back of the phone or on a label on the bottom of the battery. If you cannot find an IMEI this way, you can usually find it in the phone’s menu or by pressing * # 06.
Using Locked Mobile Devices: If the phone is unlocked, the first priority is to stop the phone from locking, touch the screen, and set the screen timeout setting to the maximum. The next step is to go to the security settings and check if any lock code is set. If the lock code is available and the code is unknown, it is conceivable that the data extraction from the phone be performed immediately at the scene.
If the display is not active when the device is found, the display should not be touched; thus, possible stains on the screen can be removed and solved by possible unlock patterns of the phone.
All modern smartphones have the option of locking the phone with the remote control command or deleting all data on the phone. This imposes the risk of losing all evidence of a device. In addition, data received after the seizure may alter or overwrite evidence and undermine the forensic soundness of your examination. Therefore, the next priority should be to disconnect the device from
Considering voice processing capability, the computer forensics service will help you ensure the overall integrity and survival of your network infrastructure. Considering computer forensics as a new element of network and computer security, known as an in-depth defense approach, will contribute to the security of your organization.
For example, understanding the legal and technical aspects of digital forensics will help you capture vital information when your network is in danger, and initiate and manage the legal process in case an intruder is caught.
You may accidentally destroy vital evidence for an attack that you may be exposed to, or you may face a situation in which your judicial evidence is deemed unacceptable in court. In addition, you or your organization may enforce new laws that require compliance with statutory regulations and assume responsibility when certain types of data are not adequately protected. Recent laws ensure that organizations are held accountable in civil or criminal courts if they fail to protect customer data.
First, those investigating computers should understand the potential evidence they are looking for to configure their search. Computer-based offenses can range in criminal activity, from child pornography to theft of personal information and the destruction of intellectual property. Secondly, the researcher should select the appropriate tools to use. Files may be deleted, damaged, or encrypted, and the investigator should be familiar with a number of methods and software to prevent further damage in the recovery process.
Computer Forensics collects two basic data types. Persistent data is data that is stored on a local hard drive (or other environment) and is protected when the computer is turned off. Temporary data is data that is stored or stored in memory and will be lost when the computer loses power or shuts down. Temporary data resides in the registry, cache, and random access memory (RAM). Because transient data is short-lived, it is important for a researcher to know the reliable ways to capture it.
System administrators and security personnel should also have a basic understanding of how routine computer and network management tasks can affect both the forensic process (the admissibility of evidence in court) and the ability to recover data that may be critical for later identification and security incident analysis.
Traditionally, organizations have invested in network forensics when they realize they need a systematic approach to addressing security and network performance issues more quickly. This is still true, but in the age of 10G and faster networks, the forensic service has become more and more important because organizations are able to perform detailed analysis of traffic through which their networks pass at speeds of 5Gbps or higher. Today’s networks transmit so much data that the only way to track traffic and troubleshoot is to record it first.Therefore, while the network forensic service is still an priceless tool for finding evidence of security attacks, it is a must-have tool for analyzing modern networks in detail.
Network Forensics Service can be applied to many situations to solve performance, security, and policy issues in today’s high-speed networks. Some examples are listed below:
• Finding evidence of security attack
• Intermittent performance troubleshooting
• User activity monitoring for compliance with IT and HR policies
• The process of identifying the source of data leaks
• Monitoring commercial transactions
• VoIP over IP and video troubleshooting
To facilitate the use of the Network Forensics service, three key capabilities are required:
Data Capture and Storage: Capability to capture and store multiple terabytes of data from high-throughput networks, including 10G or even 40G, without dropping or hijacking any packets.
Data Discovery: After the data has been saved to the storage media, the solution can be used to identify certain items of interest, such as IP address, application, context, and so on. You should provide a means to filter using. To find specific network calls or individual packets on time.
Data Analysis: Automated analysis, including expert analysis describing the content of network events, helps IT engineers quickly identify abnormal or other important network events. Once identified, they can come in and make the appropriate corrections.
