One of the main reasons people move from Windows to Linux is the promise of greater security from malware on the Internet. Everyone knows you need to add extra security to try to keep a Windows desktop safe, but what do you have to do to accomplish the same thing on Linux? To answer that question, we asked a number of well-known Linux kernel hackers and a security expert for their thoughts on the matter.
Ted Ts'o, Linux hacker extraordinaire, and an IBM employee whose latest assignment is heading up platform strategy at the Linux Foundation, has been running Linux on his desktop without a firewall for years. He says he knows more about networking and Linux platform security than the typical user, so he feels safe even without a firewall.
