Paul over at Tenable Security Podcast has put together a concise video on how to integrate Nikto directly into Nessus. Definitely worth watching if you're trying to get that set up.
Seccubus automates regular vulnerability scans and provides delta reporting. On 8/1, the project released version 1.5 "The DefCon Edition." This version includes support for controlling Nikto through Seccubus directly, leveraging the NBE report format which Frank Breedijk (Seccubus' author) wrote and released with the 2.1.2 version of Nikto.
In addition to working with Seccubus, Frank's NBE report format should allow for easy Nikto integration into any program which supports Nessus imports.
Nikto has won a security-database.com "Best IT Security Tools for 2009" award in the open source category for application scanners. An award is a testament to the great work Dave has done in 2009 to keep Nikto updated, accurate and relevant even as the web is changing at lightning speeds.
InformIT has a series on turning the OLPC into a "Hacker's Toolkit," which of course includes the Usual Suspects of tools (including Nikto) used by those evil hackers. The article is a bit cheesy in places, but I'm impressed the OLPC can run the toolset as described. Not bad for $188.
These projects are related to Nikto, or incorporate/use the Nikto databases in some fashion.
