A General Model and Guidelines for Attack Manifestation Generation
Paper i proceeding, 2007
Many critical infrastructures such as health care, crisis management and financial systems are part of the Internet and exposed to the rather hostile environment found there. At the same time it is recognized that traditional defensive mechanisms provide some protection, but has to be complemented with supervisory features, such as intrusion detection. Intrusion detection systems (IDS) monitor the
network and the host computers for signs of intrusions and intrusion attempts. However, an IDS needs training data to learn how to discriminate between intrusion attempts and benign events. In order to properly train the detection system we need data containing attack manifestations. The provision of such manifestations may pose considerable problems and effort, especially since many attacks are not successful against a particular system version. This paper
suggests a general model for how to implement an automatic tool that can be used for generation of successful attacks and finding the relevant manifestations with a limited amount of effort and time delay. Those manifestations can then promptly be used for setting up the IDS and countering the attack. To illustrate the concepts we provide an implementation example for an important attack type, the
stack-smashing buffer overflow attack.
