External Network Penetration Test

The external network penetration test simulates an attacker’s access to the system in a possible attack. Unlike other penetration tests, external network penetration testing is more detailed than automatic vulnerability scans because it examines external IT systems for any vulnerabilities that a potential attacker could use to compromise network integrity, confidentiality, or usability. It is an authorized and effective attack attempt against the servers of the company or institutions.

External Network Penetration Test Methodology


It is decided which systems are included in the external network pentest that is planned to be performed, and the time period in which the team will perform the tests.

Data collection:

Information is collected without direct communication with the target systems and without leaving a trace with the Internet.


Various intrusion attempts are made in the target system to observe how the system reacts.

  • Static analysis: To estimate how an application behaves when running its code, the entire code is scanned in a single pass.
  • Dynamic analysis: Real-time information about an application’s performance is obtained by checking the code of an application in action.

Gaining Access:

Web application attacks such as cross-site scripting, SQL injection, and backdoors are used to address vulnerabilities in the target. Testers then attempt to exploit these vulnerabilities, often by increasing privileges, stealing data, and seizing traffic to understand the damage they may cause.

Cleaning Traces:

Malware used during the test is removed from the systems.


The information available as a result of the tests is delivered to the customer with an executive summary and a report containing detailed security vulnerabilities.

Frequently Asked Questions About External Network Penetration Test

Why Should I Have External Network Penetration Testing?2020-03-13T23:14:48+03:00

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).

All of the Software and Hardware Equipments in My System Have the Latest Technology, Do I Still Need Penetration Testing?2020-03-13T23:14:34+03:00

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.

What Methods and Tools are Used for External Network Penetration Testing?2020-03-13T23:14:20+03:00

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.
