Linux, which is even newer than Windows and is not controlled by a single commercial entity, can be expected to have even more vulnerabilities than Windows. Hemmendinger commented, "I see a lot more stuff coming across BugTraq [about Linux] than any flavor of Unix or any Microsoft operating system." BugTraq is a popular forum for discussion of computer security vulnerabilities. It is moderated by SecurityFocus, now a division of security firm Symantec.
