What aspect does the Open Source Security Testing Methodology Manual (OSSTMM) primarily assess?

The Open Source Security Testing Methodology Manual (OSSTMM) is fundamentally focused on the structured assessment of security practices within organizations. Its primary goal is to provide a framework for evaluating and improving the maturity of an organization’s security posture. By employing the methodologies outlined in the OSSTMM, security professionals can assess how well an organization’s security controls are implemented and how effective they are in mitigating risks.

This assessment encompasses various aspects of an organization’s security, such as physical security, operational security, compliance, and information security. The OSSTMM emphasizes a thorough analysis to determine not just vulnerabilities but also the overall readiness and response strategies of an organization in the context of their security framework.

In contrast, other options focus on narrower aspects of security, such as specific vulnerabilities, attacker tactics, or stages of cyberattacks, which are important but do not capture the comprehensive maturity assessment that the OSSTMM is designed to facilitate.
