Episode 211: Fundamentals of Penetration Testing (Domain 5)

Certified: The CompTIA Security+ Audio Course

Penetration testing goes beyond identifying vulnerabilities—it simulates real-world attacks to see how systems, defenses, and teams hold up under pressure. In this episode, we explore the foundational concepts of penetration testing, starting with physical tests that assess physical security through social engineering, badge cloning, or simulated intrusions. We then differentiate offensive testing—where testers proactively look for exploitable flaws—and defensive testing, which focuses on hardening systems in response. Integrated penetration testing combines both, offering a holistic view of security from multiple perspectives, often aligned with red, blue, or purple team exercises. These assessments measure not just technical exposure, but procedural response and detection capabilities. A well-scoped, well-executed pen test is one of the most valuable security assessments an organization can perform—it reveals not only what can go wrong, but how prepared you are when it does.
