Application of network security situational awareness in power information system security

Abstract The increasingly complex network environment leads to more and intense attacks. Traditional firewall intrusion detection technology cannot guarantee the security of power information system, so space situation awareness becomes most important in field security. Big data can be used better understand operation network, different types for rapid analysis. Build a system framework that integrates collection, processing, storage, analysis presentation filter out harmful ensure In this paper, basic concept situational are briefly introduced. Firstly, Flume Kafka obtain log or attack information, MapReduce Storm technologies batch real-time achieve perception Then, analytic hierarchy process (AHP) is determine index weight, extract characteristics situation, complete evaluation by analyzing constructing decision matrix. has high availability, scalability easy deployment, which support prediction various threats.
