Question About Security Software for Ubuntu

[Georgina Joyce]

> I use clamav for virus protection and spamassassin for spam filtering.
> Both are very accessible, are automatically updated on a regular basis,
> and come in Debian packages. In addition, spamassassin can be
> configured stochastically, i.e. so it learns as it goes, if you want to
> take the trouble to tell it about false positives and false negatives.
> My email services have their own filters, but mine still catch things
> from time to time. I have not played with the stochastic configuration,
> but it's there if one wants to.
> 
> But Linux security is more than just virus and spam. It would pay to
> dig into the subject a bit. A good firewall is a start, and running
> only essential services and daemons.

Yes, but we have to start at the level of the original questioner's
understanding.  He / she may not even realise the relationship between
debian and Ubuntu, for example.
