Difference between a vulnerability assessment and a penetration testing!

Vulnerability Assessments

A vulnerability assessment is the process of running automated tools against defined IP addresses or IP ranges to identify known vulnerabilities in the environment. Vulnerabilities typically include unpatched or mis-configured systems. 

The purpose of a vulnerability scan is to identify known vulnerabilities so they can be fixed, typically through the application of vendor-supplied patches. Vulnerability scans are critical to an organisations’ vulnerability management programme. The scans are typically run at least quarterly, though many experts would recommend monthly scans.

Penetration Tests

One of the initial phases performed by a penetration tester is to perform a vulnerability scan to learn the IP addresses, device type, operating systems and vulnerabilities present on the systems. The next phase of a penetration test is exploitation which takes advantage of the vulnerabilities identified in the system to escalate privileges to gain control of the network or to steal sensitive data from the system.

Both should be performed

Although vulnerability assessments and penetration testing have different goals, both should be performed to improve the overall security of the information system by a skilled information security professional. The vulnerability assessment should be performed regularly to identify and fix known vulnerabilities on an on-going basis. The penetration test should be performed by a skilled and experienced penetration tester at least once a year and definitely after significant changes in the information systems environment to identify exploitable vulnerabilities in the environment that may give a hacker unauthorized access to the system.
