protection relays

About this tag
Protection relays are critical components in industrial control systems and energy infrastructure, used to safeguard electrical networks and equipment. Discussions on WindowsForum.com cover vulnerabilities in major relay families such as Siemens SIPROTEC 5 and Hitachi Energy Relion 670/650, as well as Siemens SIRIUS 3SK2 safety relays. Topics include CVE-2025-40570, a USB denial-of-service flaw in SIPROTEC 5 relays, and CVE-2025-1718 affecting Hitachi Energy devices. The forum also addresses broader CISA ICS advisories and mitigation strategies for securing protection relays against cyber threats. These threads emphasize patching, physical security, and best practices for maintaining reliability in critical infrastructure.
