Nessus is een security scanner die een netwerk kan scannen op bekende exploits en openstaande services. Let daarbij wel op dat het programma alleen gebruikt mag worden wanneer je toestemming hebt om de veiligheid van het netwerk te controleren. De lange lijst met exploits en openstaande services kan eventueel verder uitgebreid worden met eigen geschreven scripts. Het pakket draait onder de meeste Posix-systemen zoals onder andere MacOS X, FreeBSD, Linux en Solaris. De ontwikkelaars hebben sinds kort versie 2.2.5 ter download staan met de volgende aankondiging:
Nessus 2.2.5, a maintenance release, has been released. It fixes several minor bugs and contains some speed improvements.
(Slight) Speed improvements:Depending on the speed of your hard drive and the OS you're running on, you may experience up to 15% speed improvement.
- Faster scan startup speed (at the expense of a slightly bigger memory usage).
- Faster scans in general
Bug fixes:Misc:
- Fixed the use of an uninitialized buffer in the shared socket code
- Fixed some uninitialized variables in nessus_tcp_scanner
- Fixed several null pointer dereferencements in libnasl
- Several other minor bugs have been fixed (see bugs.nessus.org for details)
If you already have a copy of Nessus installed, please note that the Nessus installer makes clean upgrades - no need to uninstall the older version prior to upgrading, and no need to re-register to get a new activation code for the plugin feed.
- New NASL function 'send_capture()'
- nessusd rotates nessusd.messages on startup if the file is too big
- Enhanced nessus_tcp_scanner
