In this video, Keith Barker covers the difference between penetration testing and vulnerability scanning. Understanding the nature of risk, how it impacts security evaluation, and the pros and cons of active and passive testing all play a role. It’s crucial for systems administrators to have an accurate grasp of how each of these pieces fit together.
Keith covers two critical concepts in this video: penetration testing and vulnerability scanning. These two form the core of accurate risk assessment in the IT world. Penetration testing consists of simulating an attack to verify a threat exists, see if it is possible to bypass security controls by actively testing them, and then evaluate the potential for any vulnerabilities to be exploited. On the other side of the spectrum, vulnerability scanning is a passive, non-aggressive process. Identifying vulnerabilities, lack of security controls, and common misconfigurations are standard objectives. Keith also underscores the importance of gaining proper authorization before engaging in even passive scanning on any network you have access to.
