A Linux port of the OpenBSD/FreeBSD Cryptographic Framework (OCF). This port aims to bring full asynchronous HW/SW crypto acceleration to the Linux kernel, OpenSwan, OpenSSL and applications using DES, 3DES, AES, MD5, SHA, PublicKey, RNGs and more.

We implement an open source conflict resolution framework that consists of a user-space C application that automatically resolves firewall rules anomalies, and b) a generic tree (called policy tree), implemented as a Linux kernel module which maintains the resolved firewall rules and enables the necessary hooks to netfilter for matching incoming (or outgoing) network packets. Tree-based data structures offer improved efficiency compared to traditional access control lists (e.g. iptables or...

A small tool to help downloading the IP block lists from I-Blocklist for Transmission/uTorrent/Vuze/etc, or converting the list to IPSET format for a kernel level IP blocker. Similar scripts are populated already. This one is written in C.

tgcd is a simple Unix network utility to extend the accessibility of TCP/IP based network services beyond firewalls. This can also be used by network analysts and security experts for penetration testing and analyze the security of their network. It's written in C Language.

DNS multiplexer. It redirect, send hostname labels, access or denied DNS packet by hostname.

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). And I think: "Maybe I can make a client...

Plugdaemon is a tool that is inspired by, but not based on, programs like plug-gw. It was originally a simpler alternative, but the connection balancing code and other features makes it a lot more versatile.

Open source firewall project for Unix systems

iplist is a list based packet handler which uses the netfilter netlink-queue library (kernel 2.6.14 or later). It filters by IP-address and is optimized for thousands of IP-address ranges.

Milkshake is a Slackware-based Linux distribution that boots from a USB stick and turns an unused PC into a home firewall/router. This project is currently in prealpha and is not intended for use yet. Please do not rate it up or down yet.

Anoubis is a Security Suite which implements a secured environment for applications. The core of the suite is an Application Firewall alongside with a Sandbox. Mechanisms to assure the authenticity of files, directories and applications are provided.

DFA library is a regular expression library capable of the classic RE syntax (i.e. - without any perl extension). Unlike many other libraries with similar functionality, a deterministic finite automata (DFA) is used. DFA was formerly called npcre, wh

iptables-TNG ( The Next Generation of iptables) An environment that can use different packet classification algorithm (eg. tuple) to support large rulesets (more than 10,000 rules) for high bandwidth networks.

Network tool for monitoring IPv4 activity. Iptraf, tcpdump, trafshow have not such ability. Gives sorted traffic load speed on each IP. Helps detect the channel overload and maybe sources of attacks. Requeres ULOG target of iptables.

GTCop Professional Security Appliance aims to provide a powerful tool for satellite communications, with enhanced QoS and bandwidth controls. As derived from IPCop Firewall, it is a stable, secure, easy to configure and maintain GNU/Linux firewall box.

The program implements the CIDR merging with whitelisting (network exclusion). Output will be summarized to be as small as possible. The program has been widely used for blacklist merge and optimization.

The ADSL optimizer is an accurate packet scheduling solution for ADSL connections, based on Linux and HTB. The solution guarantees low latency while maintaining full utilization of both upstream and downstream, without wasting link capacity.

Tool for use with IPFilter to do "port knocking" and grey-list filtering of SMTP connections.

Amber - a "grey list" for Qmail. Amber sits in the tcpserver chain, not accepting or rejecting mail but deferring connections from new IP addresses for some time (default five minutes) before it starts accepting mail from them.
