- Abstract:
-
Security audit, which is the basis of intrusion detection, provides the necessar y data for intrusion detection analysis. In traditional security audit and intru sion detection system, the characteristics of an attack need to be defined by ex perts for the system to be able to successfully identify anomalous activities. D ue to the difficulty in predicting attack data, in most cases administrators onl y get normal sequences of system calls. In this paper, a security audit system b a sed on SVDD algorithm was designed to resolve the oneclass problem in anomalo us activity detection. All activities deviating from normal patterns were classi fied as potential intrusions. In experiments using the international standard da ta set MIT LPR, the oneclass classifier achieved a 100% detection rate and a z ero false alarm rate for sequences of system calls based on a small training dat aset. The proposed algorithms can be trained for anomalous activity detection si mply by using normal samples and the algorithm also enables the security audit s ystem to detect new types of anomalous behavior.
