This blog entry marks the 200th post for this blog. I've been very pleased with the content we've created for our Nessus users and customers. The feedback I've received is that the content here is useful to information security practitioners from all walks of life.
Tenable recently released Nessus plugin #30000. This means that there are roughly 20,000 plugins (although some have been retired) in the current archive. Raw counts of vulnerability tests are very deceiving, however we feel very strongly that crossing this plugin ID count is a milestone worth noting.
We try to be very open about which checks are available by providing a public RSS feed of new plugins, dynamically listing the unique count of CVE and Bugtraq IDs addressed and by allowing the public to search our plugins database. We've also provided detailed advanced notice of changes to the plugins database such as when we moved our severity scoring algorithms from CVSSv1 to CVSSv2. We have also provided an in-depth statistical analysis of the types of plugins available.
