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.

ATTENTION: Snare Lite is unsupported legacy software. While it will remain a part of the SourceForge community, it is no longer secure and compliant. For up to date Snare software check out Snare Enterprise. https://www.snaresolutions.com/try-snare-for-free/ Snare Enterprise was created to keep up with the fast paced security software market. It started with the desire to create premium logging and SIEM tools that were agnostic by nature so they could be used to boost any SIEM architecture regardless of third party developers. In fact, the agnostic nature allows it to bridge gaps between multiple SIEM implementations across business units. For more on use cases, check out the Intersect Alliance website. https://www.snaresolutions.com/ Snare Enterprise’s premium features include: - Regulatory Compliance - TLS Encryption - Log Simulcasting - TCP – Guaranteed Log Delivery - USB Device Monitoring - And more!

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 ...

Count traffic from users with dynamic ip addresses. Uses information from application level (Samba, pppd, etc.) to operate on network level (modify ipfw or another firewall rules for traffic counting).

glFlow is a robust, fast, portable, pcap-centric (D)DoS detection tool.

FWNUA (Free Windows Network User Accounting) runs silently in a Windows login script or GPO and collects data about user logins. FWNUA keeps track of the workstations logins so you don't have to! FWNUA now supports syslog and Splunk! Look for the fwnua - syslog version in the files list. Use Splunk or your own syslog server with data mining tools to create a robust user tracking system. Find our Spunk app on Splukbase: https://splunkbase.splunk.com/app/2773/
