SOC (Security Operation Center)Security Operations Center is a central location where information security teams monitor, detect and analyze cyber security incidents and improve the cyber security situation. The aim is to ensure the cyber security of the institution by using various combinations of technological solutions. In this process, SOC teams monitor and analyze activity on networks, servers, databases, applications, and other systems, investigating a security incident or abnormal activity that could be considered a threat. Collaborate with the institution's Incident Response team to ensure that security issues are quickly addressed after they are identified.
One Security Operations Center (SOC) must not only identify threats, but also analyze them, investigate the source, report on vulnerabilities discovered, and plan how to prevent similar threats in the future. In short, it must deal with security issues in real time while seeking ways to improve the organization's security posture.
A SOC team is responsible for various activities including Asset discovery, behavioral monitoring, Incident response, recovery and remediation, security improvement.
SOC ensures the monitoring of assets to detect security events by gaining awareness of all hardware, software and technologies used in the organization. SOC teams are responsible for the corporate technologies they are responsible for protecting and the technologies they use to protect the systems.
SOC constantly analyzes systems for rapid detection and prevention of abnormal activity in the system. In this sense, it enables reactive and proactive measures to be taken.
All activities taking place in the systems of the organization should be kept by the SOC teams. These logs can allow for re-examination of past actions that may have caused the security incident and detection of the breach.
Security events that occur on systems can have different degrees of severity. SOC teams assign events a severity ranking to prioritize security events that are more risky than others.
SOC teams perform Incident Response actions such as isolating the system and terminating harmful processes in any security event.
After a security incident occurs, SOC teams begin work to restore systems and recover lost or compromised data. After this intervention, the systems are restored to their pre-event state.
Following a security incident, SOC teams are responsible for knowing exactly how, why and when the security incident occurred. During this investigation, SOC teams use logs and other data obtained to investigate the problem back to its source. This research also helps prevent similar security incidents in the future.
Cybercriminals develop the methods and tools they use with the ever-evolving technology. In turn, SOC teams must make continuous planned improvements in systems to stay one step ahead of cybercriminals in order to ensure the security of institutions.
All actions performed by SOC teams must comply with standards, laws.
The Security Operations Center offers organizations several benefits. As time is one of the most critical elements in an effective cyber security incident response, SOCThe primary benefit of having security incidents is the earliest detection of security incidents through continuous monitoring and analysis of systems and cyber intelligence findings. In this way, the gap between the moment of the attack and the moment it is detected is reduced. This ensures that the risks faced by the systems are limited and threats are eliminated as soon as possible.
To create an efficient SOC; a strategy must be developed, the right tools and personnel must be invested, the SOC must be tailored to specific needs and risks. What is needed in the process of creating an efficient SOC should be well determined and a strategy should be applied accordingly. The SOC to be created must have access to anything that can affect its security status. The right tools and services for the SOC must be selected and invested in. Especially; Security information and event management (SIEM), Endpoint Protection Systems, Automatic Application Security, Firewall, Asset Discovery System, Data Monitoring Tool, Governance, Risk and Compliance (GRC) System, Vulnerability Scanners and Penetration Testing, Log Management System services and tools should be used. In the recruitment process, talented and self-developing personnel should be selected. After the staff is included in the team, necessary investment should be made in training to develop staff skills. Top security analysts in the SOC team; Must have Ethical Hacking, Forensics (Digital Forensics), Reverse Engineering, IPS (Intrusion Prevention System) Expertise skills. Different options should be considered when creating an SOC. It is important to choose the most appropriate type of SOC for the organization. Internal SOC with full-time staff and physical room on-premises, Virtual SOC consisting of part-time staff working in coordination to resolve issues as needed, Outsourced SOCs where some or all functions are managed by an external Managed Security Service Provider (MSSP) can be considered as an option for the type of SOC to be used.
SIEM (Security Information and Event Management) in Turkish, “Security Information and Event Management” collects and organizes data from all sources on the network and provides data so that SOC teams can quickly detect attacks and take action, simplify threat management, and minimize risk. SIEM is critical for SOC tasks such as monitoring, incident response, log management, compliance reporting. SIEM helps the SOC automate aggregation of logs and create rules that can greatly reduce false alerts. For these reasons, SIEM makes SOC more effective in securing organizations.
While SOC focuses on monitoring, detecting and analyzing the security status of an organization, the main purpose of NOC (Network Operation Center) is to monitor and analyze network performance, network speed and downtime in the network and solve any problems that arise. . SOC teams analyze the security status of the system and take necessary action before an organization's data or systems are compromised. NOC teams look for issues that could slow down network speed or cause varying downtime. Both examine issues in real time to prevent them from impacting customers or employees, and continually seek ways to make improvements so that similar issues don't recur. SOC and NOC Teams must collaborate to resolve major incidents and crises in enterprise systems with the best efficiency.
5 key things your SOC will do: Proactive detection of malicious network and system activity. Instead of waiting an average of 206 days for their companies to detect a violation, you want to be notified as soon as possible to minimize the impact of the violation. Being able to reconfigure the defense configuration before the threat hits you with Threat Awareness See what could be compromised against new threats in your network thanks to Vulnerability Management Awareness of hardware and software assets running in your network; be aware of what kind of threats you are exposed to your assets Having the ability to complete forensics to you and any authority if you are exposed to a security incident or unauthorized access through Log Management These are the main functions you want in your SOC such as compliance monitoring and others. There is no question that they are all critical functions to ensure your company is protected.
