Learn why." lang: en-GB --- Utilities # Physical Isolation for Power Grid and Utility SCADA Utility networks bridge physical infrastructure and digital control. When those control paths are compromised, the consequences extend far beyond data loss to affect millions of people who depend on essential services. - SCADA compromise - Ransomware in EMS - Third-party vendor access - DER and smart-meter risk Back to Control: https://fire-vault.com/solutions/control Image: Electrical grid control room with transmission pylons beyond (https://fire-vault.com/assets/sector-square-energy-41JUMkCc.jpg) The exposure in numbers 01 SCADA path isolation from corporate IT 100% SCADA path isolation from corporate IT 02 Persistent remote access to control systems Zero Persistent remote access to control systems 03 Control modules deployed per utility zone 6 Control modules deployed per utility zone 04 NIS2 and NERC CIP compliance evidence Full NIS2 and NERC CIP compliance evidence The Challenge ## Utility control systems face converging threats. 01 ### IT/OT Convergence Smart grid modernisation creates network paths between corporate IT and operational technology that attackers traverse to reach control systems. 02 ### Legacy SCADA Systems Decades-old SCADA and RTU equipment lacks modern security capabilities and cannot be patched without risking operational disruption. 03 ### Smart Meter Attack Surface Advanced metering infrastructure creates millions of network endpoints that expand the attack surface into previously isolated distribution networks. Utilities > When utility control systems are reachable from corporate networks or the internet, every software vulnerability becomes a potential service disruption affecting millions of people. The Scenario ### Scenario: Smart Grid Supply Chain Attack Attackers compromise a firmware update server for smart meter head-end systems. The malicious update propagates to distribution management systems through the AMI network, eventually reaching SCADA workstations via shared network segments. Operators lose visibility into distribution grid status across an entire region. Restoration takes nine days because backup SCADA configurations were stored on network-attached infrastructure that was also compromised. With Control, the AMI network is physically separated from SCADA systems. Verified control-plane baselines are held on infrastructure that has no live network path to production and require multi-party authorisation to release. The compromised firmware cannot traverse into control systems because the network path does not exist. "Our penetration test showed that from a compromised smart meter head-end, there were only three hops to the SCADA master. Three hops between a meter and the ability to open breakers across the distribution network." Module deployment · utility network ## Where each Control module is deployed across a utility network. Utility estates run along the Purdue model: cloud and corporate at the top, an industrial DMZ in the middle, supervisory and basic control below it, and the physical plant at the bottom. Control puts a real boundary at every level so a problem on one side does not become a problem on the others. Grounded in NIST SP 800-82 Rev. 3, IEC 62443-3-2, NERC CIP-005 and ENISA Smart Grid guidance. L5 Cloud / Internet DMZ External Customer portal Cloud services Public reach, untrusted by default.
