d97f5503f10321059cd43269ac5f60529aabdbc377241beee4a5c1b65a186534Increasing Performance in High Speed NIDS is a paper discussing a number of methods to increase performance in Snort and also NIDS in general. Discusses bottlenecks that Snort has, a brief history of snort pattern matching, and the work that Silicon Defense did with Aho-Corasick_Boyer-Moore, discussing the differences between network grep and protocol analysis.
337737f0c2eeefdc2058b99a8043d983e504f5cd46712753df479953689227e6HAP-Linux is a collection of security related patches which are designed to be applied after Solar Designers Openwall patches are installed. Changes include some extra information in the printks, and the ability to allow hard links to files you don't own which are in your group, and the ability to follow links & pipes in +t directories if they are not world-writable. This is useful for getting various daemons to run chrooted as a non-root user, and some secure drop- directory stuff.
552dd35b52705c6f4314d2fbacd357c66afb6fdeeaacea6b3e9985d2b2b25b81RSTunnel (Reliable SSH Tunnel) allows you to tunnel through data between two networks in a secure and encrypted tunnel. It uses SSH to connect the two machines. This will setup a tunnel for you, and make sure that it's constantly running.

5c7e9df2bb329004b551a8c035de176728b73494dc8b559eafe3ccef9cc05c2dInflex is an email scanner which encapsulates your existing sendmail server setup. It scans both incoming and outgoing email and it does not alter your current /etc/sendmail.cf file. It can scan for email viruses, unwanted file types (eg. EXE, BMP, MPEG) and file names (eg. prettypark.exe). It can also be used to scan for text snippets within emails.

It features a set of highly configurable danger thresholds (with sensible defaults provided), verbose alert messages that include the source, destination, scanned port range, begin and end times, TCP flags and corresponding nmap options (Linux 2.4.x kernels only), email alerting, and automatic blocking of offending IP addresses via dynamic configuration of ipchains/iptables firewall rulesets. In addition, for the 2.4.x kernels psad incorporates many of the TCP signatures included in Snort to detect highly suspect scans for various backdoor programs (e.g. EvilFTP, GirlFriend, SubSeven), DDoS tools (mstream, shaft), and advanced port scans (syn, fin, Xmas) which are easily leveraged against a machine via nmap.
