Abstract: A cyber security restoration engine takes one or more autonomous remediation actions to remediate one or more nodes in a graph of a system being protected back to a trusted operational state in order to assist in a recovery from the cyber threat. The cyber security restoration engine has a tracking component the operational state of each node in the graph of the protected system. The communication module also cooperates with the cyber security restoration engine to communicate with at least one of an external backup system and a recovery service to invoke backup remediation actions and/or recovery remediation actions to remediate one or more nodes potentially compromised by the cyber threat back to a trusted operational state, for example the state before the detected compromise by the cyber threat occurred in the protected system.
