Offensive Security Testing. Offensive security proactively assesses and tests organisation defences in a controlled manner and assess how effective security defences are. Offensive security encompasses various methodologies including penetration testing, vulnerability assessments and red teaming.
Vulnerability Assessments (VAs) is an assessment of all possible vulnerabilities that exist in given system. Penetration testing is a bit similar in that it attempts to find vulnerabilities but with the added goal of exploiting found vulnerabilities to simulate a real-world attack. Red Teaming is a slow and quieter process than pen-testing as it aims to test the blue-team’s defences over time (APT).
