Internal Penetration Testing

An internal penetration test seeks to emulate the latest tactics, techniques and procedures (TTPs) used by malicious actors who manage to gain access to the organization’s internal perimeter. In this type of assessment a ByterArmor engineer will conduct a thorough scan of the network while attempting to identify potential vulnerabilities in the organization’s information assets. Subsequently, it will execute controlled attacks on the internal network, which will vary from common exploitation techniques to advanced attacks on the Active Directory infrastructure, with the main objective of gaining access to computers through lateral movement, compromise of privileged user credentials, security services. network, and information exfiltration. This approach allows us to evaluate the resistance and security of the organization’s internal infrastructure, identifying and strengthening possible weak points that could be exploited by malicious actors once they can penetrate the external perimeter.

Methodologies used

Our engineers rely on the most widely used international frameworks such as the NIST SP 800-115 Technical Guide for Information Security Testing and Evaluation, the Open Source Security Testing Methodology Manual (OSSTMM), and the OWASP Testing Guide (v4), as well as making use of custom testing frameworks.
