SSHGuard protects hosts from brute-force attacks against SSH and other services. It aggregates system logs and blocks repeat offenders using several firewall backends, including iptables, ipfw, and pf.

Flexible web-based firewall log analyzer, supporting netfilter and ipfilter, ipfw, ipchains, cisco routers and Windows XP system logs, and mysql or postgresql database logs using the iptables ULOG or NFLOG target of netfilter others mapped to the ulogd format with a view. Fully supports IPv6 for database logs, and netfilter and ipfilter system file logs. Also supports Maxmind's GeoIP version 2 location databases. For Linux, FreeBSD, OpenBSD, Solaris, OSX,etc.

A java wrapper for popular "libpcap" and "WinPcap" libraries. Accurate full API translation. Packet buffers delivered with no copies. Send custom packets, gather statistics. Comprehensive and easily extensible DPI engine.

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 nftable maps), especially for large systems with a huge number of rules. Preliminary analysis from our implementation on ARM-based embedded systems examines efficiency and scalability of our framework. To reference this work: A. ...

Honeybrid is a network application built to 1) administrate network of honeypots, and 2) transparently redirect live network sessions (TCP or UDP) from one primary destination host to a secondary destination host.

redWall is a bootable CD-ROM Firewall with Snort, snortsam, dansguardian and support for fwbuilder, spamassassin, reporting (using ACID/sarg/ntop/webfwlog), VPN (FreeSWan/PoPToP/Openvpn) and mail alerting (by mail). Configs are stored on a Floppy or USB

What are the packets rejected by your Netfilter based firewall today ? How often this suspicious host try to connect to your box ? What are the most rejected domains ? Who is this strange host which scan your ports ? The responses are in the iptables log

Bruteblock allows system administrators to block various bruteforce attacks on UNIX services. The program analyzes system logs and adds attacker's IP into IPFW table effectively blocking them. Addresses are removed from the table after expiration period

BASE+ (Basic Analysis and Security Engine) is based on ACID project. This application provides a web front-end to query and analyze the alerts coming from various IDS systems (e.g. Snort).

readlog is a pair of scripts for reviewing iptables firewall logs via a handy web interface using a MySQL backend.

LogCop is a set of turn-key bash/firewall/awk scripts for enhancing an IDS. It monitors system logs and blocks IP addresses based on such criteria as illegal user names from repeated attacks. In production under Linux, FreeBSD, OS X, Solaris.

IP Traffic Volume: Logs (counts) in- & outgoing bytes through network device(s) using kernel iptables. Highly configurable as to which bytes are logged, e.g. to/from specific ports or ip-addresses. Data displayed in html via cgi or plain ascii to console

The Titan Firewall is an interface Web to manage firewall based on Linux with iptables. It supports filtrate of packages, NAT, logs, VPN's... Implemented in Java and jsp.

Green Screen: A Linux based Advanced Syslog Server for Juniper NetScreen Firewalls - Can be expanded later to support other products. It can capture syslog messages, parse them, store them in a MySQL database. A Web GUI interface is also included.

Traffic Control is a Linux toolbox to control squid, NAT, and other services traffic limits. TF uses Linux iptables to count traffic. This utility consists of two parts. The first is server side (written in Perl) and the second part is the interface.
