This webinar describes a system engineering approach to assess and mitigate cyber-physical security risks emanating from remote access to operational networks. The findings include the need to implement and maintain a strong combination of role-based access control and attribute-based access control.
This Webinar describes the security requirements for remote services to access intelligent electronic devices on an electric power utility’s operational network. A model-based system engineering methodology based on Zachman’s lifecycle framework is used to assess the risks and potential means to mitigate these risks. The Webinar stresses the need to combine role-based and attribute-based access control to protect the integrity and confidentiality of the sensitive data. If sensitive data is compromised, a trusted platform is needed to securely collect and safeguard the evidence needed for forensic analysis. Furthermore, several third-party security certificate trust issues are highlighted. Also, to safeguard electronic evidence, we focus on the high-priority requirements for a trusted electronic device. For example, the need to bind the remote user’s identity to the mobile device in use (personal devices) raises multiple challenges. In the event of a remote breach of the operational network, we focus on the need to protect the chain of evidence to develop an effective mitigation strategy.
This webinar is presented by Dennis K. HOLSTEIN, of CIGRE Working Group D2.40, "Security Requirements for EPU Remote Services”, that published the Technical Brochure 762 (available from www.e-cigre.org), in 2019.
