How is a compliance check different than a vulnerability scan?
A. Nessus 3 can perform vulnerability scans of network services and also log onto servers to discover any missing patches. However, the lack of vulnerabilities does not mean a server is configured correctly. The advantage of using Nessus 3 to perform vulnerability scans and compliance audits is that all of this data can be obtained at one time. Having knowledge of how a server is configured, how it is patched, and which vulnerabilities it has can help to prioritize systems for mitigating risk.
