Free Agent: Linux Firewalls and Antivirus--Needed or Not?
Linux has a reputation for being virus- and spyware-free, but you might want to add a little insurance.
Windows XP, left unpatched, is vulnerable to malware that can make it shrivel up and die within a few minutes of being connected to the Internet. Even after patching, Windows is still subject to virus and spyware attacks that make third-party security tools a must. Linux, on the other hand, has a reputation for being relatively impervious to attack via the Net. But is it really immune to the threats that stalk Windows?
The answer has long been, and still is, a qualified yes. Sure, occasionally viruses, worms, and rootkits are written specifically to compromise Linux systems. But if you avoid a couple of major blunders, those relatively few threats are unlikely to do you any real harm, for reasons I'll go into below. To sleep utterly soundly, however, you may still need to take some steps to malware-proof your Linux system.
The Tables Have Turned
The first reason your Linux system is probably safe from attack: Recent versions of Linux (kernels 2.4 and 2.6) include a built-in firewall called "iptables" that simply drops all uninvited incoming connections by default. If a worm or a person tries to break into your Linux box from afar, or not so afar, iptables simply turns away and ignores the incoming connection--the attacker won't know whether a system even exists at the attacked address.
If you don't run mail, Web, FTP, or other servers on your Linux system, you'll probably never need to modify iptables' default settings. However, if you use the Samba server suite to enable file and printer sharing with other local systems, you will have to enable incoming connections to the Samba server in iptables.
