Suricata is an Intrusion Detection and Prevention (IDS/IPS) engine developed by the Open Information Security Foundation and its supporting vendors. The engine is multi-threaded and has native IPv6 support, file extraction capabilities, and many more features. It's capable of loading existing Snort rules and signatures, and supports many frontends through Barnyard2.
LibHTP is a security-aware parser for the HTTP protocol and the related bits and pieces. That can mean many things, but the only scenario in which LibHTP has been tested so far is the one when you need to parse a duplex HTTP stream that you have obtained by passively intercepting HTTP traffic. Just feed the raw TCP stream to LibHTP and it will do the rest.
NSIA (Network System Integrity Analysis) is a Web application monitoring system that scans sites for potentially unwanted context such as defacements, unauthorized changes, errors, information leaks, profanity, and compliance issues. It operates as an IDS (Intrusion Detection System) for Web sites.
Hawk IDS/IPS is a lightweight log analyzer which was designed to be fast and efficient. It scans log files on the fly and bans IPs which make too many password failures. It adds iptables rules to reject the IP addresses. You can define the logfiles. Hawk provides a unique Web interface and flexibility, and supports sshd, dovecot, courier, pure-ftpd, proftpd, cPanel, and DirectAdmin.
StopHack is a simple to use and easy to install intrusion prevention system. It is fully adaptable and easily customized to your environment. It is built on top of proven bandwidth arbitration technology so the traffic passing through it won't be slowed down. Every packet is analyzed with regular expression-based behavior anomaly detection, and hackers are blocked immediately. It prevents reflected cross-site scripting, SQL injection, directory traversal, reflected URL redirects, login brute forcing, remote shell execution, and more.
redBorder IPS is a high performance intrusion prevention system based on Snort running on top of a clustered pf_ring with specific enhancements. A Web management interface is provided to control a large number of such devices, including snort and device configuration, rule management, SNMP monitoring, user roles, and multi-domain support.
LoginIDS provides functions to analyze log files from different services in order to detect unusual login behavior. The normal user behavior is learned by analyzing log files and saved in a database. Logins are analyzed by time, service, source, and destination address. If a user's login is new or considered unlikely by LoginIDS, an alert is generated. Alerts can be handled by external scripts and viewed using the log file management system Splunk and the LoginIDS App.
The Securepoint Unified Threat Management (UTM) security solutions provide all important security applications (firewall, VPN gateway, virus scanner, spam filter, Web filter, IDS, etc.) within a corresponding server environment, to ensure smooth updates of all systems and to make the everyday usage of these systems successful and secure for companies. They are available as UTM hardware appliances, as virtual appliances, and as a pure software solution which can be installed on standard computer systems and may be adjusted according to individual requirements. Securepoint is Windows 7-ready and supports IKEv1 and IKEv2.
Cyberprobe is a distributed architecture for real-time monitoring of networks against attack. The software consists of two components: cyberprobe, which collects data packets and forwards it over a network in standard streaming protocols; and cybermon, which receives the streamed packets, decodes the protocols, and interprets the information. Cyberprobe can optionally be configured to receive alerts from Snort. In this configuration, when an alert is received, the IP source address associated with the alert is dynamically targeted for a period of time. Collecting data and forwarding over the network to a central collection point allows for a much more "industrialized" approach to intrusion detection. The monitor, cybermon, is highly configurable using LUA, allowing you to do a great many things with captured data: summarize, hexdump, store, and respond with packet injections.
