There is a considerable amount of confusion in the industry regarding the differences between vulnerability scanning and penetration testing, as the two phrases are commonly interchanged. However, their meaning and implications are very different.
A vulnerability assessment simply identifies and reports noted vulnerabilities, whereas a penetration test (Pen Test) attempts to exploit the vulnerabilities to determine whether unauthorized access or other malicious activity is possible. Penetration testing typically includes network penetration testing and application security testing as well as controls and processes around the networks and applications, and should occur from both outside the network trying to come in (external testing) and from inside the network.
