Dynamic Defense Architecture for the Security of the Internet of Things

Abstract

The security situation of the Internet of Things (IoT) is constantly changing. Traditional passive management strategies for IoT can not adapt to the complicated environment of IoT. To solve the above problem, a dynamic defense architecture for the security of IoT is proposed. It is made up of six security defense segments which include active defense, threat detection, security warning, security response, security recovery and defense assessment. The whole procedure of security defense repeats all along. The next segment provides supplements to the previous segment. IoT security threats are dealt with dynamically. According to operation results of all defense segments, the security situation of IoT is assessed, and then defense strategies for IoT are updated to make the proposed architecture adapt to the IoT environment.
