PENETRATION TESTING AND VULNERABILITY MANAGEMENT SERVICES

A penetration test (pen test) is an ethical and controlled cyberattack simulation performed to determine the resilience of an IT system against external and internal threats. The goal is to discover security vulnerabilities on behalf of the organization before malicious actors can exploit them and to determine how critical those vulnerabilities are. This process is one of the most effective ways to test the security of an organization's digital infrastructure.

Cybersecurity is no longer just the responsibility of the IT department; it is an organizational imperative. Today, cyberattacks target not only large corporations but also SMEs, healthcare organizations, educational institutions, and public bodies. Threats such as ransomware, identity theft, and system takeovers are increasing daily. Most of these threats occur due to simple misconfigurations or overlooked security vulnerabilities.

Penetration tests are a proactive security step to anticipate and prevent these risks. Furthermore, standards and regulations such as the Personal Data Protection Law (KVKK No. 6698), KamuNET, the Information and Communication Security Guide (BİGR), ISO/IEC 27001 Information Security Management System, and ISO 27701 mandate or strongly imply the need for organizations to conduct regular penetration tests.

At 4Dimension, we conduct our penetration testing services in accordance with international methodologies (OWASP, OSSTMM, NIST, PTES). We manage the process through the following steps:

1. Planning and Reconnaissance:
Customized targets and test scope are defined. Network maps are drawn; protocols to be used, IP blocks, and test scheduling are finalized. If social engineering or email tests are required, they are planned during this phase.

2. Vulnerability Scanning:
Potential security vulnerabilities in the system are identified using up-to-date vulnerability scanning tools and manual methods. Web applications, servers, databases, network devices, and wireless networks are analyzed within this scope.

3. Exploitation:
We test whether the identified security vulnerabilities can actually be exploited. During this step, attack simulations are performed, such as authentication bypass, data exfiltration, and RCE (Remote Code Execution).

4. Privilege Escalation and Lateral Movement:
If a system has limited user access, we test whether this can be escalated to higher privileges. We also analyze the potential for internal network spread by moving from one system to another (lateral movement).

5. Evidence Collection and Cleanup:
All actions performed during the test are documented; system stability is never compromised. At the end of the test, no traces are left behind, ensuring the organization's business continuity is not harmed.

6. Reporting and Results Sharing:
Every step is documented in detail. Vulnerabilities are classified according to their risk levels. Solutions are provided for every finding. The report is presented in two separate formats, including both a technical report and an executive summary.
