Privacy, Security, Encryption I've bored the readers of my personal website to death with two rather prosaic articles debating the Linux security model, in direct relation to Windows and associated claims of wondrous infections and lacks thereof. However, I haven't yet discussed even a single program that you can use on your Linux machine to gauge your security. For my inaugural article for OSNews, I'll leave the conceptual stuff behind, and focus on specific vectors of security, within the world of reason and moderation that I've created and show you how you can bolster a healthy strategy with some tactical polish, namely software.

Firewall won't save you from anything by itself and the only meaningful reason of using fws is when certain hosts need access to certain service. On a workstation you can pretty much disable/remove every network daemon like ssh, apache, mysql etc. or if you need them to develop stuff then just bind them to localhost.

A local firewall is very useful, even on a Linux computer when it's directly connected to the internet (home, free public WIFI, etc).

There are a lot of network based attacks that computers without firewalls are vulnerable to.

man in the middle attacks, spoofing, etc. It also keeps ports that shouldn't be exposed to the internet away from the internet.
