NIST 800-53 Rev 5 / CSF 2.0
NIST Compliance with CtrlLayer
The NIST Cybersecurity Framework is the gold standard for security programs, adopted by over 50% of U.S. organizations. NIST 800-53 Rev 5 provides the specific control catalog that federal agencies and their contractors must implement. CtrlLayer addresses key control families across both frameworks, providing the endpoint-level controls that close gaps in your security program.
NIST Cybersecurity Framework
The five core functions that organize cybersecurity activities at their highest level.
Asset Management & Risk Assessment
Understand the cybersecurity risk to systems, people, assets, data, and capabilities.
- Asset Inventory (ID.AM): Application discovery engine catalogs all software across managed endpoints. Device telemetry provides hardware inventory with OS version, configuration, and health status.
- Risk Assessment (ID.RA): Security Master agent performs continuous threat scoring and posture assessment. Each device receives a composite risk score based on configuration, patch level, threat indicators, and behavioral patterns.
- Governance (ID.GV): Centralized policy management with version tracking, change attribution, and compliance baseline definitions.
Access Control & Data Security
Develop and implement safeguards to ensure delivery of critical services.
- Access Control (PR.AC): RBAC+ABAC policy engine with app-scoped, just-in-time elevation. Zero standing privileges. QR-based third-party delegation without credential sharing.
- Data Security (PR.DS): AES encryption for agent communication, TLS 1.3 for all API traffic. USB storage control prevents unauthorized data extraction.
- Protective Technology (PR.PT): Audit logs with hash-chain integrity. Network connection monitoring. Application execution control through software library management.
- Awareness and Training (PR.AT): Elevation prompts reinforce least-privilege principles at the point of action, embedding security awareness into daily workflows.
Anomaly Detection & Monitoring
Develop and implement activities to identify cybersecurity events.
- Anomalies and Events (DE.AE): Blue Team correlation engine detects suspicious patterns including brute force, lateral movement, privilege escalation, and policy bypass. 48,000+ threat intelligence indicators cross-referenced in real-time.
- Security Continuous Monitoring (DE.CM): Agent provides continuous endpoint monitoring — network connections, process execution, USB activity, authentication events. All events streamed to central platform for correlation.
- Detection Processes (DE.DP): Configurable detection rules with severity classification and automated escalation. Detection results are reviewed and improved based on incident findings.
Incident Response & Mitigation
Develop and implement activities to take action regarding a detected cybersecurity incident.
- Response Planning (RS.RP): Pre-configured automated response playbooks can isolate devices, revoke privileges, and block USB access upon threat detection.
- Analysis (RS.AN): Hash-chain audit logs provide tamper-proof forensic evidence for incident investigation. Complete timeline reconstruction of events leading to and following an incident.
- Mitigation (RS.MI): Real-time containment actions — device isolation, privilege revocation, policy enforcement — limit blast radius of security incidents.
- Communications (RS.CO): Severity-based alerting and escalation workflows ensure appropriate stakeholders are notified of incidents.
Recovery Planning & Improvements
Develop and implement activities to restore capabilities impaired during a cybersecurity incident.
- Recovery Planning (RC.RP): Post-incident compliance checks verify affected devices are restored to compliant baselines. Centralized policy re-enforcement ensures consistent recovery.
- Improvements (RC.IM): Incident analysis feeds back into security policies, detection rules, and response playbooks. Blue Team dashboard tracks improvement metrics over time.
NIST 800-53 Rev 5 Control Families
Specific control implementations that satisfy 800-53 requirements.
Access Control
Account Management
Centralized user account management with role assignment, multi-step onboarding, and email verification. Automatic privilege revocation upon role change or termination.
Access Enforcement
RBAC+ABAC policy engine enforces approved authorizations for logical access. Every elevation request is evaluated against applicable policies before execution.
Separation of Duties
Elevation approval workflows separate the requester from the approver. Administrators who approve policies are logged separately from users who consume them.
Least Privilege
App-scoped elevation grants minimum necessary privilege for specific applications only. Just-in-time access with automatic expiration. No permanent admin rights.
Remote Access
VPN-less agent architecture provides authenticated, encrypted, and monitored access from any network location. Every remote action is logged and attributable.
Audit and Accountability
Event Logging
Comprehensive event capture: authentication, elevation requests, policy changes, USB events, network connections, application launches, and security incidents.
Content of Audit Records
Each audit record includes event type, timestamp, source, outcome, user identity, device identity, application context, and integrity hash.
Audit Record Review
Blue Team correlation engine continuously analyzes audit records, flagging suspicious patterns and generating security incident reports automatically.
Protection of Audit Information
Hash-chain integrity verification ensures audit records cannot be altered without detection. Tampering with any record invalidates the entire chain downstream.
Non-repudiation
Cryptographically signed elevation grants bind user identity to action to timestamp. Users cannot deny having performed logged actions.
Configuration Management
Baseline Configuration
Security Master defines and monitors compliance baselines across all managed endpoints. Deviations from baseline trigger alerts and can initiate automated remediation.
Least Functionality
Software library management restricts which applications are permitted on managed devices. Application discovery identifies unauthorized software for review.
System Component Inventory
Automated application discovery and hardware telemetry maintain a current inventory of all system components across the managed fleet.
User-Installed Software
Elevation control prevents unauthorized software installation. Users cannot install software without an approved elevation grant, which is logged and time-limited.
Identification and Authentication
User Identification and Authentication
Unique user identifiers with JWT-based authentication. No shared accounts. Multi-factor verification available for privileged actions.
Identifier Management
Centralized identity lifecycle management — from onboarding with email verification through role assignment to deprovisioning with full privilege revocation.
Authenticator Management
QR-based tech delegation eliminates credential sharing. Agent authentication uses signed JWT tokens with expiration. No static service account passwords.
System and Information Integrity
Flaw Remediation
Windows Update management provides centralized visibility into patch status across the fleet. Non-compliant devices are flagged for remediation.
Malicious Code Protection
Security Master agent detects threats using behavioral analysis and threat intelligence matching. USB control blocks a primary malware introduction vector.
System Monitoring
Continuous endpoint monitoring across network connections, process execution, USB activity, and authentication events with real-time correlation and alerting.
Software, Firmware, and Information Integrity
Hash-chain audit integrity verification. Anti-tamper protections on the agent. Application hash verification for software library management.
