I recently came across a couple good security-related articles that's well worth reading.
The first is an introduction to firewalls and backdoors, describing each type, listing examples, and providing tips. Also contains links to some very useful external resources. http://securityfocus.com/infocus/1701
The second article disusses real-time alerting with snort, the most popular open-source IDS (Intrusion Detection System). http://newsforge.com/article.pl?sid=03/06/09/1939256. It does not cover installation or initial configuration, however; check out the snort documentation for details on this.
After many years of development, the final draft of the 802.11g standard has been approved. 802.11g specifies wireless data rates of up to 54 Mbps, while maintaining backwards compatability with older (and slower) 802.11b products.
Researchers at Advanced Micro Design released details on new high-performance transistors that will be used as a building block for future microprocessor designs.
Using a combination of two new technologies, metal gates (made from Nickel Silicide) and fully-depleted silicon-on-insulators (FDSOI), researcher were able to demonstrate up to a 30% performance gain over today's transistors.
Much more information can be found in the Full story.
