INTRUSION DETECTION USING SYSTEM CALL MONITORS ON A BAYESIAN NETWORK |
摘要 |
Selected system calls are monitored to generate frequency data that is input to a probabilistic intrusion detection analyzer which generates a likelihood score indicative of whether the system calls being monitored were produced by a computer system whose security has been compromised. A first Bayesian network is trained on data from a compromised system and a second Bayesian network is trained on data from a normal system. The probabilistic intrusion detection analyzer considers likelihood data from both Bayesian networks to generate the intrusion detection measure.
