Integrated network intrusion detection

摘要: Intrusion preludes may be detected (including detection using fabricated responses to blocked network requests), and particular sources of communications singled out for greater scrutiny, by performing intrusion analysis on packets a firewall. An integrated system uses an end-node firewall that is dynamically controlled invoked-application information policy. The use various alert levels trigger heightened monitoring states, alerts sent security operation center, and/or logging activity later forensic analysis. monitor traffic block violates the policy, detect prelude, from potential intruder when prelude detected. also track behavior applications policy identify abnormal application behavior, abnormally behaving intrusion.
