Is Windows now playing catchup to Linux?

“If someone puts a backdoor into Linux, someone will eventually find it. Once it is found, I can eliminate it, rebuild the kernel, and get back up and running safely within minutes.

And even if you could, eliminating it yourself would be equally difficult because you don’t have the source code to rebuild the kernel.” More at LinuxWorld.com.
