Abstract
Intrusion Detection Systems (IDSs) are necessary components in the defense of any computer network. Network administrators rely on IDSs to detect attacks, but ultimately it is their responsibility to investigate IDS alerts and determine the damage done. With the number of alerts increasing, IDS analysts have turned to automated methods to help with alert verification. This research investigates this next step of the intrusion detection process. Some alert verification mechanisms attempt to identify successful intrusion attempts based on server responses and protocol analysis. This research examines the server responses generated by four different exploits across four different Linux distributions. Next, three techniques capable of forging server responses on Linux operating systems are developed and implemented. This research shows that these new alert verification evasion methods can make attacks appear unsuccessful even though the exploitation occurs. This type of attack ignores detection and tries to evade the verification process.
