OSSEC
OSSEC is a free, open-source host-based intrusion detection system. It performs log analysis, integrity checking, Windows registry monitoring, rootkit detection, time-based alerting, and active response.

Snort
Snort is the foremost Open Source Intrusion Prevention System (IPS) in the world. Snort IPS uses a series of rules that help define malicious network activity and uses those rules to find packets that match against them and generates alerts for users.

In the vast, sprawling universe of cybersecurity tools, OSSEC and Snort find themselves remarkably alike, like two intergalactic hitchhikers sharing the same improbably improbable guidebook. Both are open-source champions, battling the forces of digital chaos in real-time while occasionally pausing to accept accolades from their communities. They integrate seamlessly with other tools, forming alliances against the dark forces of malware and mischief. Enterprises, small businesses and the odd solitary sysadmin hail them as heroes, despite their occasional quirks and fondness for frequent updates.

OSSEC, hailing from the sunny shores of Brazil circa 2004, is the sort of tool that prefers to sit quietly on your server, sipping logs and keeping an eye on file integrity like a particularly vigilant tea-drinking aunt. Its true calling is in the realm of host-based intrusion detection, ensuring your system doesn’t run off to elope with a rootkit. Compliance auditing is its party trick, though it insists you install an agent on each system, which might sound needy, but is rather endearing when you see it in action.

Snort, by contrast, has been darting through network traffic since 1998, a proud creation of the United States, like apple pie or improbable election results. It thrives on spotting nefarious patterns in packets, preventing your network from becoming the galactic equivalent of a dingy pub full of dubious characters. With its rules-based signature system, it’s less about tea and more about the thrill of the chase, analyzing gateways and routers without the fuss of agents. It’s the tool for those who enjoy network drama but prefer it safely intercepted.
