Cyber security for smart grid
- 1. CYBER SECURITY FOR SMART GRID HUMAN-AUTOMATION INTERACTION FrAME- WORK BY S. A. s. VINEELA REDDY M.KRITHIKA B.E. EEE III YEAR SCSVMV UNIVERSITY
- 2. SMART GRIDS
- 3. NEED FOR CYBER SECURITY FOR SMART GRID The ability to deliver electric power to customers reliably. Accurate billing. To prevent from threats.
- 4. STEPS INVOLVED BY CYBER INTRUDER The cyber attack can be decomposed into three steps: 1.Intruder intends to have control over the SCADA system. 2.The intruder should identify the system to launch an intelligent and effective attack. 3.The attacker initiates the control of Firewall Enhancement Protocol, Application server, Systems database, and even controllers directly.
- 5. HUMAN - AUTOMATION INTERACTION FRAMEWORK Human – Automation interaction • Determining limits of automation. • Start or stop of automatic process. • Providing information to the automatic process. Level of Automation Ten levels were adapted to control the automatic accessing of the system.
- 6. Performance Shifting Characters The Environmental conditions which affects the performance of human automation system are termed as PSF. Based on the vulnerabilities of power grid at he time of cyber attack, there are 5 kinds of PSFs. PSF 1: Number of weak points in the power grid PSF 2:Power grid complexity PSF 3:Number of entry points PSF 4: Data flow in the IT infrastructure. PSF 5: Anomalies and Signatures.
- 7. SOLUTION METHODOLOGY – Subjective Approach
- 8. RELATION BETWEEN PSF AND LOA
- 9. PSF VECTOR The PSF vector describes systems condition in choosing the level of automation. LOA = f(PSF) PSF = (PSF1, PSF2 ……….. PSF5)
- 10. SCENARIO DEVELOPMENT BASED ON THE RESULT OF PSF VECTOR SCENARIO 1 – Happy condition PSF = [ 0,0,0,0,0] SCENARIO 2 – Vulnerable condition PSF= [ 2,0,0,0,0] SCENARIO 3 - Complex condition PSF = [ 0,2,0,0,0]
- 11. SCENARIO 4 – Accessible condition PSF = [0,0,2,0,0] SCENARIO 5 – Previous condition PSF = [0,0,0,2,0] SCENARIO 6 – Unexpected condition PSF = [0,0,0,0,0,1]
- 12. PSF RANKING
- 13. CONCLUSION An approach for human – automation framework based on adaptive automation using expert judgments has been presented. The paper outlines five environmental conditions and their impact on cyber security. The environmental conditions are ranked based on their effect on the environment.
