The Tao of Network Security Monitoring: Beyond Intrusion Detection - The Tao of Network Security Monitoring is one of the most comprehensive and up-to-date sources available on the subject. It gives an excellent introduction to information security and the importance of network security monitoring, offers hands-on examples of almost 30 open source network security tools, and includes information relevant to security managers through case studies, best practices, and recommendations on how to establish training programs for network security staff.

Encrypting Shell Scripts - Do you have scripts that contain sensitive information like passwords and you pretty much depend on file permissions to keep it secure? If so, then that type of security is good provided you keep your system secure and some user doesn't have a "ps -ef" loop running in an attempt to capture that sensitive info (though some applications mask passwords in "ps" output).

A 2005 Linux Security Resolution - Year 2000, the coming of the new millennium, brought us great joy and celebration, but also brought great fear. Some believed it would result in full-scale computer meltdown, leaving Earth as a nuclear wasteland. Others predicted minor glitches leading only to inconvenience. The following years (2001-2004) have been tainted with the threat of terrorism worldwide.

The encryption factor
27th, January, 2005

Quantum computing is set to revolutionise the way we work. Trouble is, it could crack any of today's security codes in a fraction of a second, says Charles Arthur.When bankers and spies begin to worry about advances in computing, the rest of us would do well to take notice. What makes them edgy are the advances being made in "quantum computing", which is, as might be expected from the name, as entangled and confusing a field to understand as the branch of physics on which it is based - quantum mechanics.

Introduction to Troubleshooting Linux Firewalls
25th, January, 2005

Oh no you sayÑnot more management speak! Please, I get enough of that already! Fear not; we promise that we won't waste your time with YAUM (Yet Another Useless Methodology). We want you to find your problem and fix it quickly. So you can call this a process, a method, a way, or if you like, call it a methodologyÑwhatever works for you. What we don't want to do is fill your head with some useless babble. This methodology is hard won from years of solving problems.

Patching up problems
28th, January, 2005

The race to plug network holes before attackers use them is running system managers ragged--so they're throwing up more barriers to stop intruders. In recent years, the common wisdom has been that keeping up-to-date on software patches is key to safeguarding a company's networks against viruses, worms and other pests. But with dozens of flaws being discovered each week, that approach has turned out to be a Herculean task.

SELinux: Playing with fire
26th, January, 2005

One of the much-talked-about features in Fedora Core 3 (FC3) is Security-Enhanced Linux, which some people believe will make Linux a truly military-grade secure operating system. But SELinux is available to secure many other distributions as well.
