Common Challenges and Solutions

Organizations implementing the NCA Critical Systems Cybersecurity Controls frequently encounter similar challenges related to critical systems identification, legacy systems, operational constraints, and resource constraints. Understanding these common challenges helps organizations plan proactively and implement CSCC requirements effectively.

Critical Systems Identification: Identifying and classifying critical systems may be challenging, particularly for organizations with complex infrastructures or interconnected systems. Organizations may struggle to identify all critical systems, classify systems based on criticality, or understand system interdependencies. Critical systems identification challenges may require significant analysis and expertise.

Solutions include conducting comprehensive critical systems inventories, implementing critical systems classification processes, and analyzing system interdependencies. Organizations should ensure that critical systems identification addresses all critical infrastructure systems, classifies systems accurately, and enables effective critical systems security management. Effective critical systems identification enables organizations to focus security efforts on critical systems.

Legacy Systems: Securing legacy critical systems may be challenging, particularly for systems that lack modern security capabilities or cannot be easily modified. Organizations may struggle to implement security controls on legacy systems, address legacy system vulnerabilities, or integrate legacy systems with modern security monitoring. Legacy systems challenges may require significant technical efforts and compensating controls.

Solutions include isolating legacy systems through network segmentation, implementing compensating controls that protect legacy systems, and planning for legacy system modernization. Organizations should ensure that legacy systems are protected through network isolation, compensating controls, and monitoring. Legacy system modernization plans should address security improvements while maintaining operational requirements. Effective legacy systems management enables organizations to protect legacy critical systems.

Operational Constraints: Implementing security controls on critical systems may be constrained by operational requirements, particularly for systems that must maintain continuous operations. Organizations may struggle to implement security controls that don't interfere with critical systems operations, balance security with availability, or implement security controls during operational windows. Operational constraints may limit security control options.

Solutions include designing security controls that address operational requirements, implementing security controls that balance security with availability, and coordinating security implementations with operations teams. Organizations should ensure that security controls enable critical systems operations while providing security protection. Effective security control design enables organizations to implement security without disrupting critical systems operations.

Resource Constraints: Implementing CSCC requirements requires significant resources including personnel, technology, and time that may be limited, particularly for smaller organizations. Organizations may struggle to allocate resources for critical systems security, particularly when resources are already committed to other priorities. Resource constraints may force organizations to prioritize some requirements over others.

Solutions include prioritizing requirements based on risk, leveraging managed security services, and engaging third-party critical systems security providers. Organizations should implement requirements progressively, achieve incremental progress, and demonstrate ongoing compliance efforts. Risk-based prioritization enables organizations to allocate limited resources effectively, addressing the most critical requirements first.

System Interdependencies: Managing security for interconnected critical systems may be challenging, particularly when systems depend on each other or share infrastructure. Organizations may struggle to understand system interdependencies, implement security controls across interconnected systems, or coordinate security with system owners. System interdependencies may create security risks that require coordinated management.

Solutions include mapping system interdependencies, implementing coordinated security controls, and establishing coordination processes with system owners.
