Regarding to differentiate between vulnerability scanning and penetration testing, there is some amount of industry, which is confusion and between their meaning and implications is very different. Normally, a vulnerability assessment identifies and reports noted vulnerabilities, but a penetration test attempts to exploit the vulnerabilities to determine whether unauthorized access or other malicious activity is possible. Typically, penetration testing 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. Basically, a manual penetration testing layers human expertise on top of professional penetration testing software and tools such as automated static binary and automated dynamic analysis when assessing high assurance applications. A manual penetration test provides complete coverage for standard vulnerability classes, as well as other design, business logic and compound flaw risks that can only be detected through manual testing.
