I used to find outgoing alerts more useful than incoming - if an internal client is sending malicious traffic, you know you have a serious problem! In contrast, incoming alerts will tell you about a whole load of failed attacks that you may well be patched against. Rule tuning on IDS varies from site to site, so I'm not going to tell you what you should be doing - do whatever you find most helpful. cheers, Jamie -- Jamie Riden / [EMAIL PROTECTED] / [EMAIL PROTECTED] UK Honeynet Project: http://www.ukhoneynet.org/ ------------------------------------------------------------------------ Test Your IDS Is your IDS deployed correctly?
