Osquery is an operating system instrumentation framework for Windows, OS X (macOS), Linux, and FreeBSD. The tools make low-level operating system analytics and monitoring both performant and intuitive. Osquery exposes an operating system as a high-performance relational database. This allows you to write SQL queries to explore operating system data. With osquery, SQL tables represent abstract concepts such as running processes, loaded kernel modules, open network connections, browser plugins, hardware events or file hashes.Osquery queries your devices like a database. Osquery uses basic SQL commands to leverage a relational data-model to describe a device. Frequently, attackers will leave a malicious process running but delete the original binary on disk. This query returns any process whose original binary has been deleted, which could be an indicator of a suspicious process.

Application Heartbeat Monitor is a daemon + library that applications register with to have their life signs monitored.

Automated Security Tools (autosec) aims to provide automatic tools which network administrators may use to help check and test the security of their network.

Insidias is a next-generation intrusion detection engine, with a focus on speed, efficiency, advanced pattern matching, parallel-processing, modularity, and expandability.

This project is dedicated to finding best of breed open source monitoring products, tools, sysadmin tools and overall systems management stuff. We will take all these components and make them work together.

Analyzes radius proxy servers by monitoring radius packets passed across the server's interface.

Shadow Watcher is a Peer to Peer log sharing tool for the security analyst. Consider it a "community watch" program which allows you to keep your system secure from the threats on the internet and help others do the same.

Syslogd2 is a syslog daemon that has been completely re-imagined specifically for use in network environments. It is multi-threaded, scalable and versatile with features designed for both network and host managers. Each Syslogd2 binary is customized from a set of over 20 features at compile-time. It can support input from text files, named-pipes, Linux kernel and user-defined Linux and (both IPv4 and IPv6) IP sockets (both UDP and TCP). It provides a pre-loadable name-cache that can replace DNS services for host-name resolution. Syslogd2 easy-to-use filters use string-matching to select messages which can then be modified, dropped, kept or re-routed (changed to new facilities). Filters are applied to inputs, outputs or both to control msg-routing and network load. Syslogd2 can spool messages on network failure and forward the spooled traffic on network restoration. Please see the wiki on this project site for more on the design features, goals and perspectives of Syslogd2 ...

Apan, Advanced Performance Addon for Nagios, is a tool that is used to store performance-related data from service-checks done by Nagios (www.nagios.org).

Passive Proxy Daemon (pproxyd) has moved to GitHub (https://github.com/rondilley/pproxyd ) This tool reads pcap format files or reads packets directly from the network, assembles web based traffic and generates squid proxy style logs.

The first stage of development is do write a tool to anonymize packet capture files captured with libpcap. After that we will be integrating this with tcpdump to anonymize in real-time and analyze and look for its effect on different IDS's.
