Genetec Inc., a technology provider of unified security, public safety, operations, and business intelligence solutions, has published a guide for utility companies on how to select a security system that supports compliance with the Critical Infrastructure Protection plan (CIP) of the North American Electric Reliability Corporation (NERC).
The 12 published NERC standards are aimed at regulating, enforcing, monitoring, and managing the security of the Bulk Electric System (BES) in North America. A subset of the full guidance follows.
Different BES Cyber Systems
CIP-002-5.1a: Cybersecurity – management controls. The goal is to categorise different BES Cyber Systems based on potential impact levels to better understand how to manage vulnerabilities and protect assets while regularly maintaining and reviewing them.
Look for a security system that can provide an up-to-date breakdown of all connected devices and their statuses, to simplify the review process and quickly identify any that require immediate attention.
Keeping critical assets
Make sure an activity trail report of access is available to simplify investigations/audits
CIP-005-6: Cybersecurity - electronic security perimeter(s). This standard aims to secure access to BES Cyber Systems by keeping critical assets within a designated electronic security perimeter and closely monitoring them in case of suspicious activity.
Organisations should ensure all security systems connected to the network infrastructure require secure authentication, encrypted communications, and users that have role-based permissions to access critical assets. Make sure an activity trail report of access is available to simplify investigations/audits.
Providing emergency support
CIP-008-6: Cybersecurity – incident reporting and response planning. To comply, put in place procedures to identify, classify, and respond to cybersecurity incidents and keep complete records of the incident and management process to report to the Electricity Information Sharing and Analysis Center (E-ISAC) for forensic analysis.
A centralised security system that keeps a complete log of network activity and access, as well as a full history of the asset configuration data, will simplify investigation and recovery when required. Utilities should look for technology partners that can provide emergency support in case of a catastrophic system failure or cyberattacks.
Clear cybersecurity guidelines
CIP-013-1: Cybersecurity – supply chain risk management. Utilities should aim to develop a plan to identify and assess risk to BES posed by vendor products or services.
It’s important to ensure all critical vendors that are supporting the smooth functioning of the BES have clear cybersecurity guidelines in place that will not put the BES at risk. Ensure system providers do not have access to their system by default without consent, particularly in system-to-system remote access.
