Network intrusion analyzer that performs real time auditing.

A review by Fernando Ortega

Snort is a free intrusion detection system for Windows PCs which works by sniffing packets and monitoring networks. It's widely used intrusion detection and prevention software (IDS / IPS).

With the analysis of packets, Snort detects whether they might be a threat to system and network security. Its community-backed contributions make it a very good way to see whether intrusions are being attempted or have happened.

With real-time analysis of network traffic, Snort uses WinPcap to read raw network data looking for probes, buffer overflows, port scans, CGI attacks and more. It displays them in an interface with several details providing information about attempted attacks.

Configuration of Snort include Global Settings, Updates, Alerts, Blocked, Pass Lists, Suppress, IP Lists, SID Management, Log Management and Sync.

Logs that the application produces are saved into a database, which currently supports MySQL, Microsoft SQL, ODBC and Oracle.

Overall, Snort is certainly a powerful network security tool which can provide some vital details about possible malicious behavior.
