Real-time attack and failure detection for next generation networks

In today's modern networks, routers rely on high-performance multi-core packet processing systems to implement a variety of applications and operations required to forward traffic. This leads to an increase in the complexity of such systems and hence the number of processing cores. Managing such processing cores and ensuring their correct operation become a difficult task. In this paper, we address this problem by proposing another novel approach to verify the correct operation of network processor and detect any attack/failure. This approach monitors the power consumption of such cores at the OS level during run-time and correlates it statistically with predetermined benchmark information. We show that based on this correlation, any failure/attack can be detected.
