OT/ICS Security

15 controls in 5 topics, each seen through the policy, process and technical lenses.

Policy

RCF-0427IR for ICSno mappings yetIncident response procedures specific to operational technology environments are formally definedRCF-0421Network segmentation (ICS)no mappings yetIndustrial control systems are formally required to be separated from corporate IT networksRCF-0418OT asset inventoryno mappings yetAll operational technology and industrial control system assets are formally required to be identified and recordedRCF-0424Patch/compensating controls (ICS)no mappings yetA formal approach manages security vulnerabilities in OT systems where traditional patching is not possibleRCF-0430Safety alignmentno mappings yetCybersecurity requirements are formally aligned with operational safety and physical process requirements

Process

RCF-0428IR for ICSno mappings yetICS-specific incident response procedures are consistently followed when operational systems are affectedRCF-0422Network segmentation (ICS)no mappings yetICS network boundaries are consistently maintained and cross-boundary traffic is strictly controlledRCF-0419OT asset inventoryno mappings yetOT and ICS assets are consistently inventoried and changes to the OT environment are trackedRCF-0425Patch/compensating controls (ICS)no mappings yetOT vulnerabilities are consistently assessed and compensating controls are applied where patching is not feasibleRCF-0431Safety alignmentno mappings yetSecurity decisions in OT environments consistently take into account the impact on operational safety

Technical

RCF-0429IR for ICSno mappings yetTechnical tools support safe detection and response to incidents in OT environments without disrupting operationsRCF-0423Network segmentation (ICS)no mappings yetTechnical controls enforce network separation between ICS and IT environments through firewalls and unidirectional gatewaysRCF-0420OT asset inventoryno mappings yetTechnical tools passively discover and maintain an inventory of OT and ICS devices without disrupting operationsRCF-0426Patch/compensating controls (ICS)no mappings yetTechnical compensating controls such as network monitoring and application whitelisting protect unpatched OT systemsRCF-0432Safety alignmentno mappings yetTechnical security controls are designed and validated to avoid interfering with safety-critical operational processes
