SOAR Cyber Response for Physically Controlled Distributed Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Physically controlled distributed systems (PCDS) face operational challenges due to cyber connections that serve as attack vectors, making them vulnerable to unauthorized access and adverse effects, with existing intrusion detection and mitigation systems being inadequate in response times and effectiveness.
Innovation Solution
Implementing a Security Orchestration, Automation, and Response (SOAR) system that integrates with Intrusion Detection Systems (IDS) to autonomously detect and respond to cyber threats, using a combination of signature and behavior-based analysis to quickly neutralize attacks and revert systems to a known good state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional intrusion detection systems are used to monitor PCDS, then detection capability is provided, but response time is too slow (averaging weeks)
Solution Approach 1:
The system performs preliminary actions by pre-configuring automated response playbooks and security policies before attacks occur. When threats are detected, pre-programmed responses are immediately executed, eliminating the weeks-long delay of manual intervention and enabling response times measured in seconds or minutes.
Solution Approach 2:
The security system serves itself through automated orchestration that detects threats, analyzes them against threat intelligence, and executes mitigation actions without human intervention. This self-service capability transforms security operations from manual processes to autonomous systems that respond instantly to threats.
2Ease of operation
If cyber connections are added to PCDS for control and monitoring, then operational capability is improved, but vulnerability to attacks increases
Solution Approach 1:
The system introduces security orchestration as an intermediary layer between cyber connections and PCDS operations. This intermediary monitors all network traffic, filters malicious content, and mediates legitimate communications, allowing operational capabilities to function while blocking attack vectors at the network layer.
Solution Approach 2:
The system implements continuous feedback loops where threat intelligence from multiple sources is constantly analyzed, and security policies are dynamically adjusted based on detected threats. This feedback mechanism enables the system to adapt to new attack methods while maintaining operational connectivity.
3Productivity
If automated SOAR playbooks are implemented, then response speed is improved, but system complexity increases
Solution Approach 1:
The security orchestration platform provides multi-functionality by consolidating threat detection, analysis, response automation, and intelligence gathering into a single unified system. This universal platform handles multiple security functions simultaneously, improving response speed while avoiding the complexity of multiple separate systems.
Solution Approach 2:
The system merges previously separate security functions (intrusion detection, threat intelligence, automated response, and incident management) into an integrated SOAR platform. This consolidation streamlines operations and improves response speed while managing complexity through unified architecture rather than multiple discrete systems.

AI summary
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.
