Re: [Trisquel-users] No Firewall?

[gnuser]

Trisquel (and Debian, which I use) don't come with a firewall controller  
installed by default. The reasons why have been debated here many times  
before, so don't hope for that to change anytime soon.
What I do is, I have all the Debian CDs and so I install the first one, and  
before I connect to the internet, I install Gufw from the CDs. That way you  
can control ports open and closed before you connect to the internet.
If you can't do that (since Trisquel doesn't work with Debian's CDs) you can  
install the CD, connect to the internet (maybe using a router firewall to  
greater protection) and install Gufw. Disconnect, configure firewall, and  
connect again.

Anyway, if you are serious about security, keep in mind that firewall is just  
one of many steps you need.
One thing you SHOULD do to increase your security is install the NoScript  
Addon for firefox/abrowser.
You might also wanna take a look at subjects such as encryption, Tor,  
rootkits (RKHunter for example), etc.
