The European Network and Information Security Agency (ENISA) recently released an interesting paper about minimum security measures for smart grid operators. The paper is aimed at improving the minimum level of cyber security services within the smart grid infrastructure. The proposed security measures are organised into three sophistication levels and ten domains, namely:
Security governance & risk management, Management of third parties, Secure lifecycle process for smart grid components/systems and operating procedures, Personnel security, awareness and training, Incident response & information knowledge sharing, Audit and accountability, Continuity of operations, Physical security, Information systems security and Network security.
