Description

Cyber security has become high priority in Industrial Automation (IA).While attacking the multiples of System means vulnerability leads to gets high. To strengthen the cyber security part of smarter grids in particular relevant priority to ensure reliable operation and govern system stability in terms of communications integrity. Here dependable operation is to ensure the secure, stable and reliable in power delivery system. Obscurity progress can be easily removed by using the IDS framework. Access control process is mainly launching the anomalous attacks. The framework provides a hierarchical approach for an integrated security system, comprising distributed IDSs. This approach is compatible with currently emerging trends toward using SIEM technology to monitor smart grids and other critical infrastructure. In this context, a novel SCADA-IDS with whitelists and behavior-based SCADA protocol analysis is proposed and exemplified in order to detect known and unknown cyber-attacks from inside or outside SCADA systems. Finally, the proposed SCADA-IDS is implemented and successfully validated through a series of realistic scenarios performed in a SCADA-specific test bed developed to replicate cyber-attacks against a substation LAN. Proposed dependable operation is to ensure the secure, stable and reliable in power delivery system. Obscurity progress can be easily removed by using the IDS framework. Access control process is mainly launching the anomalous attacks.
