Systems and methods for blocking, detecting and responding to cyber attacks in physically controlled distributed systems
Systems and methods that provide Security Orchestration, Automation, and Response (SOAR) technologies that equip cyber-defenders with new capabilities to autonomously respond to network and host-based system alerts, threat hunting results, and cyber intelligence data streams. Systems and methods provide a novel SOAR approach for networked systems where such networked systems include PCDS systems such as DERs. System may ingest data from multiple Intrusion Detection Systems (IDSs) to quickly block attacks and revert PCDS systems to known good states via a collection of IDS technologies including Bump-in-the-Wire (BITW) devices which incorporate physical and cyber data to detect abnormal and potential malicious behaviors.
1 . A Security Orchestration, Automation, and Response (SOAR) system for a plurality of physically controlled distributed system (PCDS), including:
a plurality of distributed Intrusion Detection Systems (IDS) in communication with the plurality of PCDS collecting cyber-physical data directed to or generated by the plurality of PCDS;
one of or a combination of at least one of plurality of distributed IDS and a SOAR system analyzing the collected cyber-physical data;
one of or a combination of the at least one of plurality of distributed IDS and the SOAR system employing at least one of a plurality of playbooks to detect one of a signature-based attack, a behavior-based attack, and a physical configuration attack on at least one of the plurality of PCDS based on the analyzed collected cyber-physical data; and
one of the SOAR system or a combination of the at least one of plurality of distributed IDS and the SOAR system responding to the attack on the at least one of the plurality of PCDS by employing at least one of a plurality of playbooks.
2 . The SOAR system of claim 1 , further including the SOAR system reverting the affected one of the plurality of PCDS to a previous known good state of operation.
3 . The SOAR system of claim 1 , wherein one of plurality of distributed IDS is a Bump-in-the-Wire (BITW) system in communication with one of the plurality of PCDS and collects cyber-physical data directed to or generated by the one of the plurality of PCDS.
4 . The SOAR system of claim 1 , wherein the at least one of the plurality of attack playbooks is employed to detect a signature-based attack.
5 . The SOAR system of claim 4 , wherein the signature-based attack playbook detects one of identify packet manipulation and Address Resolution Protocol (ARP) spoofing.
6 . The SOAR system of claim 1 , wherein the at least one of the plurality of attack playbooks is employed to detect a behavior-based attack.
7 . The SOAR system of claim 6 , wherein the behavior-based attack playbook detects of one identifies adversary reconnaissance and denial-of-service attempts.
8 . The SOAR system of claim 1 , wherein the at least one of the plurality of attack playbooks detects a physical configuration attack.
9 . The SOAR system of claim 8 , further including the SOAR system reverting the affected at least one of the plurality of PCDS to a previous known good state of operation when one of the plurality of attack playbooks detects a physical configuration attack.
10 . The SOAR system of claim 1 , wherein one of the plurality of attack playbooks is employed to detect a signature-based attack, a second one of the plurality of attack playbooks is employed to detect a behavior-based attack, and a third one of the plurality of attack playbooks is employed to detect a physical configuration attack.
