Arming Linux against hackers

A more secure version of Linux created by the US National Security Agency is free to download

Don't be naive enough to think that because you run Linux you won't be a target for hackers. If you rely on Linux for hosting or transmitting sensitive data, you should check out Security-Enhanced Linux, created by the US National Security Agency (NSA) and available for free.

First released to the public in January 2001, Security-Enhanced Linux (SELinux) is a research project from the NSA that seeks to enhance the open-source Linux kernel: to provide greater protection against corruption; to prevent the bypassing of application security procedures; and to mitigate the destruction caused by malicious or defective applications.
