Application Research on Retrospective Analysis System in Network Intrusion Detection
Wei Wu, Nan Cheng, Yubin Wang · 2014
In the wake of the rapid development of internet, the information security issue brought about by the internet has been increasingly prominent, e.g. data leakage and hacker attack. Despite that many protective measures have been proposed to solve those issues, such as building firewall, applying for secure routing technology and installing antivirus programs, those measures are unable to ensure the absolute security of the network and tracing the source of the issues. In order to realize the in-depth analysis on warning security risks in the network, this paper introduces several common methods of intrusion detection and the retrospective analysis technology, analyzes the advantage of retrospective analysis system compared to other common methods of intrusion detection, sets forth the design principle of the retrospective analysis system, and concludes that retrospective analysis system is superior to other intrusion detection systems based on an experiment.
