DSACR: A defense-based system with adaptive cyber resilience for industrial control systems

Industrial Control Systems (ICS) security happens often, which makes it hard for many organizations to keep a balance between operational efficiency, system efficiency, and security. A major concern is how to protect information security and make sure that ICS keep working. This study thus presents a defense-based system with adaptive cyber resilience (DSACR). DSACR will optimize the configuration with respect to the three indices of operational efficiency, performance, and security. Whenever an assault event happens, DSACR offers protective solutions depending on the threat level to optimize the security and running costs of recovering ICS. In terms of safety and operation, DSACR is superior to other approaches by 3 % and 11 %, respectively, as shown by the results of the experiments.
