Bro - Network Security Monitor
- 224
Bro is a powerful network analysis framework that is much different from the typical intrusion detection system you may know. Bro provides a comprehensive platform for more general network traffic analysis as well.
Bro is a passive, open-source network traffic analyzer. It is primarily a security monitor that inspects all traffic on a link in depth for signs of suspicious activity. More generally, however, Bro supports a wide range of traffic analysis tasks even outside of the security domain, including performance measurements and helping with trouble-shooting.
Bro comes with built-in functionality for a range of analysis and detection tasks, including extracting files from HTTP sessions, detecting malware by interfacing to external registries, reporting vulnerable versions of software seen on the network, identifying popular web applications, detecting SSH brute-forcing, validating SSL certificate chains, and much more.

OpenWIPS-ng is an open source and modular Wireless IPS (Intrusion Prevention System). It is composed of three parts: Sensor(s): "Dumb" devices that capture wireless traffic and sends it to the server for analysis. Also responds to attacks. Server: Aggregates the data from all sensors, analyzes it and responds to attacks. It also logs and alerts in case of an attack. Interface: GUI manages the server and displays information about the threats on your wireless network(s).

fail2ban - Daemon to ban hosts that cause multiple authentication errors
Fail2Ban scans log files like /var/log/auth.log and bans IP addresses having too many failed login attempts. It does this by updating system firewall rules to reject new connections from those IP addresses, for a configurable amount of time. Fail2Ban comes out-of-the-box ready to read many standard log files, such as those for sshd and Apache, and is easy to configure to read any log file you choose, for any error you choose. Though Fail2Ban is able to reduce the rate of incorrect authentications attempts, it cannot eliminate the risk that weak authentication presents. Configure services to use only two factor or public/private authentication mechanisms if you really want to protect services.

stenographer - Stenographer is a packet capture solution which aims to quickly spool all packets to disk, then provide simple, fast access to subsets of those packets
Stenographer is a full-packet-capture utility for buffering packets to disk for intrusion detection and incident response purposes. It provides a high-performance implementation of NIC-to-disk packet writing, handles deleting those files as disk fills up, and provides methods for reading back specific sets of packets quickly and easily.It’s fast because it doesn’t do this. Even with the very minimal, single-pass processing of packets we do, processing ~1Gbps for indexing alone can take >75% of a single core.
