And I wanted a program that would go beyond the constraints of Tripwire."File System Saint - Self-described as, "File System Saint is a light in weight host-based intrusion detection system with primary focus on rate and ease of usage."Snort Self-described as "Snort ® is an open source network invasion prevention and detection system taking advantage of a rule-driven terminology, which integrates the advantages of trademark, process and anomaly based assessment approaches. With millions of downloads to date, Snort is the most commonly deployed intrusion detection and prevention modern technology worldwide and has come to be the de facto requirement for the sector."For more information on Fixing Your Computer or on finding Computer Repair in Wilmington you can contact us at: Delaware PC Tech, 1201 North Orange Street Suite 700 #757E, Wilmington, DE 19801, 302-416-5963
