View Full Version : Important Security Updates

If Linux / Ubuntu are generally "safe" from malware, etc., why do I receive so many "important security updates" from the Update Manager? We all know what an "important security update" means in the Windows world...

Those important security updates keep it safe. Most are released before any sort of security hole has been exploited. The same is true for Windows. In fact, a lot of Windows exploits occur AFTER an update is release for it. A few exploits do occur before a Windows update comes out, but the majority happen after. Ever heard of Exploit Wednesday (http://en.wikipedia.org/wiki/Patch_Tuesday#Exploit_Wednesday)?

The famous Sasser (http://en.wikipedia.org/wiki/Sasser_(computer_worm)) worm exploited a hole in Windows that had been patched 17 days earlier.

Linux is safer because it is based on UNIX (which by it's very nature is safer than the Windows NT system) and because desktop Linux is generally not targeted by malware makers. However, Linux is not flawless. Security updates are necessary for all operating systems and most programs. This is why Firefox, OpenOffice, Rhythmbox, etc. all get security updates.

Thanks for the reply. No, I didn't know about Exploit Wednesday. Thanks again.
