Hardened Linux is a secured and minimalized distribution based on Slackware. It is designed to run as firewall, IDS host, authentication system and VPN gateway. PaX and SSP is included.
Drop specified IP n seconds remotely, auto-undrop it when timeout.
It's a IDS-receiver and written in C.
Sometimes I want to drop remote IP xx seconds, and Undrop it when timeout;
Sometimes my sniffer-server find a hack-action and I want to tell another server/server-group "Drop xxx.xxx.xxx.xxx IP xx seconds".
So I written this program -- dynipdrop("dynipdrop" daemon and "ipdrop_local" to send a drop-msg from localhost, and "ipdrop_udp" to send a drop-msg to another server(installed the dynipdrop daemon).
The Kernel Intrusion Detection System-KIDS, is a Network IDS, where the main part, packets grab/string match, is running at kernelspace, with a hook of Netfilter Framework. The project is not ready for use, then incomplete pieces of code may be found.

The Master-Slave project is directly related to the Snort IDS to dynamically create rules into iptables firewall. It could send the attacker IP address to others machines into the circuit that will block the IP address before any attack from the intruder
Bait and Switch combines IDS tech (Snort primarily) and Honeypots into a new, more valuable, reactive system. After receiving an alert, B&S protects your server by silently redirecting hostile traffic to a honeypot while leaving other traffic alone.
Krome Shield is designed to fool remote fingerprinting tools (using ICMP & TCP), making them think you're running a different OS. It runs under Linux, using the netlink device and ipchains. In the future it will act like an IDS too, detecting attacks a
This toolkit will provide seemless backend support for multiple Firewall and IDS systems deployment. The initial release will only support Snort and FreeBSD\\\'s ipfw, but future releases will expand the firewall selection. The main code is Python,
This is a Firewall and IDS front-end, the main purpose is simplify configuration of Iptables and Fwsnort and Psad management. The Firewall provides an experimental feature to decide in real-time about each outgoing connection.
