Nessus 4 Released by Tenable

| Brett D. Arion |
A little gift for the holiday weekend, Tenable announced Thursday that Nessus 4 has been released. Some of the updated functionality includes:

Nessus Engine

  • Uses the same engine on Windows and Unix-based systems for a unified experience on all platforms and more consistent results
  • Fully thread-based (as opposed to process based) for better scalability and reduced memory usage
  • Performance improvements to reduce CPU usage on all platforms

Port scanners

  • Local and remote port scanners can now be combined. For example, if you select the Nessus SYN scanner and the netstat WMI portscanner , Nessus will try to log in via WMI to enumerate the ports first, then to fall back to the SYN scanner
  • The TCP SYN port scanner has been rewritten entirely and operates the same between Windows and Unix-based systems
  • Native UDP port scanner (ProfessionalFeed Only)

Compliance Checking

  • The database compliance checks can now log into MSSQL over SSL
  • The PCI-DSS plugins are now fully supported

NASL (Nessus Attack Scripting Language)

  • Added support for Perl Compatible Regular Expressions (PCRE) to NASL
  • NASL scripts can now share results between hosts via a global knowledgebase
  • New NASL functions (XML parsing, the bignum library, new packet forgery functions, new socket-related functions and more)

NessusClient

  • Support for XLST transformations of the reports - This is one of the most exciting features and will be described in more detail in upcoming blog posts.
  • The ability to export a .nessus file based on a filtered report
  • Unlimited number of filters for the NessusClient on Windows and Unix-based systems

Cross-Platform

  • No external libraries are required, eliminating the need to tamper with your system configuration in /etc/ld.so.conf
  • Added support for the newest Linux distributions (Debian 5, Fedora 10, etc.)
  • New "linux-generic32" and "linux-generic64" builds for additional linux distributions
  • 64-bit native builds of Nessus/NessusClient for FreeBSD, Windows and Linux
  • All the Unix command-line tools (e.g., nessus-fetch, 'nessus', nessuscmd) now also run on Windows

Be sure to check it out today. I know I'm going to be playing with it this weekend...
