Cybersecurity Basics: Protecting CUI for Federal Contracts

Understanding Controlled Unclassified Information

NIST Special Publication 800-171 Requirements

Access Control: Limit system access to authorized users and restrict what those users can do based on their roles and responsibilities. Implement multifactor authentication for privileged accounts and remote access.
Awareness and Training: Ensure personnel understand their security responsibilities and can recognize and respond to security threats. Provide regular training on policies and procedures.
Audit and Accountability: Create and maintain audit logs that enable tracking of user activities and system events. Protect audit information from unauthorized access and modification.
Configuration Management: Establish and maintain secure baseline configurations for systems and components. Control and document changes to configurations.
Identification and Authentication: Verify the identity of users, processes, and devices before granting access. Use strong authentication mechanisms appropriate to risk levels.
Incident Response: Establish procedures for detecting, reporting, and responding to security incidents. Test incident response capabilities periodically.
Maintenance: Perform regular maintenance on systems while protecting CUI. Control tools used for maintenance and ensure maintenance personnel are authorized.
Media Protection: Protect physical and digital media containing CUI throughout its lifecycle including storage, transport, and disposal.
Personnel Security: Screen individuals before granting access to systems containing CUI. Ensure departing personnel no longer have access.
Physical Protection: Limit physical access to systems and equipment to authorized individuals. Protect facilities and equipment from environmental hazards.
Risk Assessment: Periodically assess risks to organizational operations, assets, and individuals from operating systems containing CUI.
Security Assessment: Periodically assess security controls to determine effectiveness. Develop and implement remediation plans for identified deficiencies.
System and Communications Protection: Monitor and control communications at system boundaries. Implement cryptographic mechanisms to protect CUI during transmission.
System and Information Integrity: Identify, report, and correct system flaws in a timely manner. Protect systems against malicious code.

Cybersecurity Maturity Model Certification

1
Determine applicable CMMC level
Review current and target contracts to identify required CMMC levels. Level determination depends on information sensitivity and contract criticality. Most contracts involving CUI will require Level 2 certification.
2
Conduct gap assessment
Evaluate current security posture against applicable CMMC practices. Identify gaps between current implementation and required controls. Document findings and prioritize remediation based on risk and timeline.
3
Develop and implement remediation plan
Create detailed plans addressing identified gaps with specific actions, responsibilities, timelines, and resources. Implement remediation systematically, documenting evidence of control implementation.
4
Prepare System Security Plan
Document your security implementation in a comprehensive System Security Plan describing how each required control is implemented in your environment. The SSP is essential documentation for assessment.
5
Conduct internal assessment
Perform self-assessment against CMMC practices to verify remediation effectiveness and readiness for external assessment. Identify and address any remaining gaps before scheduling third-party assessment.
6
Schedule and complete certification assessment
Engage a CMMC Third Party Assessor Organization for Level 2 certification or prepare for government-led assessment for Level 3. Maintain evidence supporting control implementation throughout assessment process.
