Internet Storm Watchers
Most of us are content with the protection a firewall affords us, and don’t bother to analyze the data the programs collect. Which ports are being probed? How often? Is the same source IP repeated with alarming frequency? We rarely check. The information locked away in those unexamined log files could potentially prevent script kiddie rampages, stop the spread of malware, and even help track and prevent hacker break-ins. And yet those files go largely unanalyzed, especially by home users. The firewall does its job, and we’re satisfied.
