Detection & Deletion of DDOS Attacks Using Multi-clustering Algorithm
Journal Title: International Journal of Innovative Research in Computer Science and Technology - Year 2014, Vol 2, Issue 4
Abstract
Wireless sensor networks are mostly vulnerable to attacks. It’s difficult to find /track attacker due to mobility. Indeed, the numbers of new attacks as well as their sophistication are continuously increasing. Diametrically opposite strategy has been studied in the last few years such as unsupervised anomaly detection (UAD). UAD uses data mining techniques to extract patterns and uncover similar structures “hidden” in unlabeled traffic or unknown nature (attack or normal operation traffic), without relying on Digital signatures or baseline traffic profiles. Based on the observation that attacks, particularly the most difficult ones to detect are contained in a small fraction of traffic flows with respect to normal operation traffic so we propose a paramount advantage of unsupervised, knowledgeindependent detection algorithms based on clustering. The main aim is to combine the clustering results provided by multiple independent partitions of the same set of flows and filtering out biased groupings. We focus on the detection and characterization of standard and well-known attacks, which facilitates the interpretation of results. Denial of service (DOS), distributed DOS (DDOS), network scans, and worm propagation are examples of such standard network attacks. The approach can easily be generalized to detect other kinds of anomalies and attacks.
