The Nessus security scanner by http://www.tenablesecurity.com/ is a valuable tool for security consultants performing network audits. Unfortunately it does lack a quick overview over the vulnerabilities (supposedly) found.
This tool will extract such a re-sortable overview as CSV table from a Nessus export.
...see the README
Each finding will be documented twice in the CSV table.
First you will find each single finding for each single IP with a count number of -9999 (versions 9.x and older: 0 = zero). After all single findings are listed, all findings are listed again summed up per finding.
Thus you get a table similar to this (abridged) one:
|4||Finding-AAA||10.1.1.2, 10.1.1.3, 10.1.1.4, 10.1.1.5,|
The "-9999" rows are ideal for GREPping out single hosts or findings, while the summary lines are ideal for a fast overview, for example:
Nessus results (and thus the ones of this tool) are a to be taken with a serious grain of salt. Don't trust them blindly but verify. Nessus is "only" a tool, a useful one, but not always a reliable one. Use Nessus (like NMAP or other scanners) for the brainless grunt work and start working.
If you need a security consultant to check your network, systems or
architecture, or to help you with a security problem/incident or
(a better approach) check your security architecture and risks,
simply contact me.
