• Synergistic Architecture for Human-Machine Intrusion Detection

  Modern day detection of cyber threats is a highly manual process where teams of human analysts flag suspicious events while using assistive tools such as Bro and Snort. It is the analysts’ ability to discern suspicious activity and authority to make decisions on threats that place humans into central roles in the threat detection process. However, over-reliance on human ability can lead to a high volume of undetected threats. As the tempo, diversity and complexity of cyberspace threats continues to increase, this shortcoming can only worsen. Therefore, there is a need for a new detection paradigm that is largely automated but where analysts maintain situational awareness and control of the process. We propose a synergistic detection process that captures the benefits of human cognition and machine computation while mitigating their weaknesses. The analyst provides context and domain knowledge, and the machines provide the ability to handle vast data at speed.
