Bejtlich and IPSxIDS

Richard Bejtlich is one of the best sources of information and reasonable opinions about intrusion detection. He wrote a very precise argument about why Detection is important even when you can use Prevention. I'll quote him here:

"traffic inspection is best used at boundaries between trusted systems. Enforcement systems make sense at boundaries between trusted and untrusted systems."

Very good!
