Firmware integrity ensures that the software running on industrial controllers and devices has not been tampered with or modified by an unauthorised party. Attackers may attempt to inject malicious code into firmware during a supply chain attack or after gaining access to the network. By verifying cryptographic signatures before installation and centrally managing updates, organisations can ensure that their hardware only runs trusted, authorised code. Our blueprint for industrial security covers these supply chain protections.
