HAproxy is a high-performance and highly-robust TCP and HTTP load balancer which provides cookie-based persistence, content-based switching, SSL off-loading, advanced traffic regulation with surge protection, automatic failover, run-time regex-based header control, Web-based reporting and management interface, advanced logging to help trouble-shooting buggy applications and/or networks, and a few other features. Its own event-driven state machine achieves 100,000 connections per second and surpasses GigaEthernet on modern hardware, even with tens of thousands of simultaneous connections.
Snort is a network intrusion detection and prevention system. It is the most widely deployed technology of its kind in the world. It performs detection using a variety of methods including rules-based detection, anomaly detection, and heuristic analysis of network traffic. Its rules language is open source and available to the public as well.
SecurityFocus ARIS Extractor is a sophisticated Intrusion Detection System (IDS) log analyzer and reporting system, integrated with the SecurityFocus ARIS web site. It allows administrators to upload Intrusion Detection System (IDS) logs to the SecurityFocus ARIS Web site, producing sophisticated reporting, and research attacks and events. By filtering out insignificant or benign data and converting it to a common (XML) format, ARIS extractor streamlines incident reporting for both security professionals and home users, allowing IDS operators to focus only on relevant attacks and incidents. It allows you to analyze and archive logged incidents, cross reference incidents/attacks with the SecurityFocus Vulnerability Database, look up contact information for offending IP addresses, generate personal incident statistics and reports, automatically identify and report important incidents, reduce the amount of time spent parsing IDS logs, and generate daily summary reports, delivered by email (optional). All of this is done without revealing any information that could be used to discern your identity. It can be configured to obfuscate IP addresses, names, and other pertinent details before submitting them to the ARIS Analyzer web site. It supports Snort, Cisco Secure IDS, Dragon, NetProwler, RealSecure, BlackICE Defender, and ICEPac.
