It depends on what you are looking for. You could set up Nessus (or nmap or something similar) to run active scans. Nessus has a (free) home feed, as well as a scheduling option. Another front end for it would be Seccubus ( http://seccubus.com/).
Something lighter would be tiger, which emails you differences/changes From the Debian description, "Debian's TIGER incorporates new checks primarily oriented towards Debian distribution including: md5sums checks of installed files, location of files not belonging to packages, check of security advisories and analysis of local listening processes." You might also check out chkrootkit and rkhunter. --b On Tue, May 14, 2013 at 3:25 PM, Pol Hallen <de...@fuckaround.org> wrote: > > Apart from subscribing to debian-security-announce? > > Hi and thanks for your reply.
