Linux® has been described as one of the most secure
operating systems available, but the National Security Agency (NSA) has taken Linux
to the next level with the introduction of Security-Enhanced Linux (SELinux).
SELinux takes the existing GNU/Linux operating system and extends it with kernel and
user-space modifications to make it bullet-proof. If you're running a 2.6 kernel
today, you might be surprised to know that you're using SELinux right now! This
article explores the ideas behind SELinux and how it's implemented.
Public networks like the Internet are dangerous places. Anyone who has a computer
attached to the Internet (even transiently) understands these dangers. Attackers
can exploit insecurities to gain access to a system, to obtain unauthorized access
to information, or to repurpose a computer in order to send spam or participate in
attacks on other high-profile systems (using SYN floods, as part of a Distributed
Denial of Service attacks). Read more at IBM.com
