Abstract

Conventional host-based and network-based intrusion and misusedetection systems have concentrated on detecting network-based andinternal attacks, but little work has addressed host-baseddetection of low-level network attacks. A major reason for this isthe misuse detection systems dependence on audit data and theabsence of low-level network data in audit trails. This workdefines low-level IP vulnerabilities and distinguishes betweenlow-level IP and IP-based vulnerabilities. Furthermore, we analyzea number of different low-level IP attacks and the vulnerabilitiesthat they exploit. We develop attack signatures for each attack,and based upon our analysis, we determine a baseline collection ofinformation needed to detect the attacks. We suggest locationswithin protocol stacks where the needed data can be collected.Finally, we generalize from the baseline audit data to try topredict audit content suitable not only for detecting theseattacks, but possible future ones.
