Cyber-Physical Systems (CPS) play a signi cant role in our critical infrastructure networks from power-distribution to utility networks. e emerging smart-grid concept is a compelling critical CPS infrastructure that relies on two-way communications between smart devices to increase e ciency, enhance reliability, and reduce costs. However, compromised devices in the smart grid poses several security challenges. Consequences of propagating fake data or stealing sensitive smart grid information via compromised devices are costly. Hence, early behavioral detection of compromised devices is critical for protecting the smart grid's components and data. To address these concerns, in this paper, we introduce a novel and con gurable system-level framework to identify compromised smart grid devices. e framework combines system and function call tracing techniques with signal processing and statistical analysis to detect compromised devices based on their behavioral characteristics. We measure the e cacy of our framework with a realistic smart grid substation testbed that includes both resource-limited and resource-rich devices. In total, using our framework, we analyze six di erent types of compromised device scenarios with di erent resources and a ack payloads. To the best of our knowledge, the proposed framework is the rst in detecting compromised CPS smart grid devices with system and function-level call tracing techniques. e experimental results reveal an excellent rate for the detection of compromised devices. Speci cally, performance metrics include accuracy values between 95% and 99% for the di erent a ack scenarios. Finally, the performance analysis demonstrates that the use of the proposed framework has minimal overhead on the smart grid devices' computing resources.

Substation is a vital part of power system where all electrical equipments are installed for transformation of electrical power from one circuit to another circuit without changing its frequency. Now a day due to economical as well as technological growth the power transferring system is totally automatically. Yet it is not applied to almost all places but most of the substations in India are automated. Power utilities adopt SCADA system for maintenance development and operation. It provides an application program for acquiring real time data from IED/RTU using open process control technology for substation monitoring. Now a day modified substation is installed with LAN system and Ethernet, such substation is design for task which uses communication system. Due to increasing combined distributed energy resources such as small photovoltaic plants or micro-cogeneration system grid leads to new competition to distribution system operation (DSO'S). TEC has developed a global communication standard. IEC 61850 is to facilitate substation automation. Communication security and reliability become important and it should be considered to ensure correct operation of substation automation system. Hence to make all automated we are trying really hard from our project. Since Substation is manually operated. It required lots of skill manpower for successful operation and it also leads to many human errors. Hence we need to automate the substation. Risk and reliability analysis of substation auto system are the most important and desirable design considered.
