Download Nessus 3.0.4

Nessus is a security scanner that can scan a network for known exploits and open services. Please note that the program may only be used if you have permission to check the security of the network. The long list of exploits and outstanding services can be further expanded with own written scripts. At the moment there are two branches that are being worked on. Namely the old and trusted 2.2.x branch that is released under the GPL and the new 3.0.x branch. This last branch has been largely rewritten and unfortunately is no longer released as open source, why the developers have taken this step is over this page to read. The developers released version 3.0.4 with the following announcement:

Tenable Network Security, Inc. is proud to announce the availability of Nessus 3.0.4 for Windows, Mac OS X, Linux, Solaris and FreeBSD. This release contains the following fixes and enhancements:

Nessus daemon (‘nessusd’):

• Processing the plugins after an update is faster
• Better detection and handling of corrupt db files
• It is now possible to use ‘default’ in a port range just like any other port (ie: ‘1,default,443,8080’)
• Avoid a deadlock in the main process when waiting for a sub process to die
• nessus_tcp_scanner works much better when used over a slow network link
• nessus_tcp_scanner now offers some options accessible thru the GUI
• If ‘log_whole_attack’ is set to ‘no’ , do not print messages about shared sockets in the logs
• Fixed the ‘on_exit()’ nasl function
• Fixed ‘nasl -k’ which would sometimes not work properly
• Avoid doing some un-necessary system calls, thus resulting in a lower load during a scan (esp. on Mac OS X)
• Fixed a bug in ssh_func.inc which would prevent it from working against HP/UX

Command-line client (‘nessus’):

• Logs much faster in a remote nessusd scanner
• Fixed a possible memory corruption issue when creating a list of plugins to launch
• Fixed a corruption of the .nessusrc files when receiving some plugin prefs ending by a space

Mac OS X specific changes:

• Opening and closing a session window would stop all on-going scans
• Creating a policy and defining it as ‘shared’ immediately saves the policies on disk

Windows-specific changes:

• Not a beta any more
• Fixed file lock issues
