DDSGA : A Data Driven Semi Global Alignment Approach for detecting Masquerade Attacks

A?masquerade?attacker impersonates a legal user to utilize the user services and privileges. The?semi-global?alignment?algorithm (SGA) is one of the most effective and efficient techniques to?detect?these attacks?but it has not reached yet the accuracy and performance required by large scale, multiuser systems. To improve both the effectiveness and the performances of this algorithm, we propose the Data-Driven?Semi-Global?Alignment,?DDSGA?approach. From the security effectiveness view point, DDSGA?improves the scoring systems by adopting distinct?alignment?parameters for each user. Furthermore, it tolerates small mutations in user command sequences by allowing small changes in the low-level representation of the commands functionality. It also adapts to changes in the user behaviour by updating the signature of a user according to its current behaviour. To optimize the runtime overhead,?DDSGA?minimizes the?alignment?overhead and parallelizes the detection and the update. It improves the hit ratio of the enhanced SGA and reduces Maxion-Towns end cost. Hence,?DDSGA?results in improving both the hit ratio and false positive rates with an acceptable computational overhead.
