Nessus Scanning with SSH Proxies

Unfortunately, Nessus does not support SSH proxying. This is a problem when scanning remote hosts behind a bastion box, especially when it is not possible to bind or connect to a new port to the bastion box due to firewall rules. Binding a port to localhost and pointing Nessus to 127.0.0.1 is also not an option as Nessus handles scanning localhost in a different way and will report issues with the scanning box itself.

In a pinch it is possible to hack around this problem by tricking the Nessus scanner into thinking it’s scanning the remote host when it is in fact connecting via a port bound to the localhost. Iptables to the rescue….

The Dangers Of Vulnerability Scoring Dependency

Vulnerability scanning has an important role in most enterprise threat & vulnerability management programmes – it provides multiple benefits to internal security teams as they identify vulnerabilities and it can also help verify control performance.  Associated vulnerability scoring systems, such as the Common Vulnerability Scoring System (CVSS), have also gained widespread industry adoption, as they are simple to understand and usually produce repeatable results.
