Security-enhanced Linux provides a locked down OS
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 U.S. NSA and available for free.
First released to the public in January 2001, Security-Enhanced Linux (SELinux) is a research project from the U.S. National Security Agency (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.
