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](https://www.agilicus.com/white-papers/industrial-cyber-security-best-practices/)
covers these supply chain protections.
