03 Control Families (CF)

Phase 1 - A suggested method would be to include in your policy, a statement that clearly defines authorized users and their roles, specifying the CUI they're permitted to access. We need to implement strong authentication measures, like multi-factor authentication, and establish a robust authorization process that grants access based on the principle of least privilege. Furthermore, the policy should detail procedures for user account management, including timely provisioning, deactivation, and regular reviews of access rights. We should also incorporate access monitoring and auditing to detect and respond to any unauthorized access attempts.

Phase 1 - A suggested method would be to include in your policy, a statement that mandates detailed audit logging for all systems processing CUI. This should include capturing user logins, data access, modifications, and deletions, along with system events. We need to establish a centralized log management system with sufficient storage to retain these logs for a defined period, as specified by regulatory requirements. Furthermore, the policy should outline procedures for regular log review and analysis, including automated alerts for suspicious activity. This will enable us to detect and respond to security incidents promptly, maintain accountability for user actions, and demonstrate compliance with NIST 800-171 Revision 3's Audit and Accountability requirements.

Phase 2 - A suggested method would be to include in your policy, a statement that explicitly states that access to systems containing Controlled Unclassified Information (CUI) requires multi-factor authentication for all users. We should define strong password policies, including minimum length, complexity requirements, regular changes, and restrictions on password reuse. Furthermore, we need to implement a robust identity management system that governs user accounts, including provisioning, de-provisioning, and access controls based on the principle of least privilege. This system should track user activity and provide audit trails. Finally, the policy should detail procedures for verifying user identities before granting access and for revoking access when necessary, ensuring compliance with NIST 800-171 Revision 3's Identification and Authentication requirements.

Phase 1 - A suggested method would be to include in your policy, a statement that Media Protection should explicitly address the following: First, we need to implement strict access controls, limiting who can access CUI stored on any media, whether it's a hard drive, USB drive, or even printed documents. This should include strong authentication and authorization measures. Second, we must detail procedures for protecting media during transport, including encryption for digital media and secure handling for physical media. Third, the policy needs to outline a clear process for sanitizing or destroying media containing CUI when it's no longer needed, specifying approved methods like degaussing or physical destruction to prevent any possibility of data recovery. Finally, we should mandate regular training for all personnel on these procedures and conduct periodic audits to ensure compliance. This comprehensive approach will help us meet the requirements of NIST 800-171 Revision 3 and protect our CUI.

Phase 1 - A suggested method would be to include in your policy, a statement that explicitly details physical security measures to protect CUI, aligning with NIST 800-171 Revision 3. This includes implementing access control systems, like keycard entry or biometric scanners, for restricted areas where CUI is processed or stored. We should maintain visitor logs, documenting all individuals entering these areas, and establish secure storage for equipment and media containing CUI, such as locked cabinets or safes. The policy should also outline procedures for regularly inspecting these physical security measures to ensure their effectiveness and address any vulnerabilities promptly, thereby preventing unauthorized access, tampering, or theft of CUI.

Phase 2 - A suggested method would be to include in your policy, a statement that defines access control procedures, including multi-factor authentication and role-based access, to limit CUI access to authorized users only. We need to define acceptable use of system resources and implement monitoring and logging to detect anomalies. For communications, the policy should mandate encryption for all CUI in transit and at rest, specifying approved cryptographic methods. It should also cover secure configuration of network devices, including firewalls and intrusion detection systems, to establish robust boundary defenses. Furthermore, the policy should address incident response procedures for security events, including denial-of-service attacks, and outline a vulnerability management program to proactively identify and mitigate system weaknesses. Finally, we should incorporate regular security assessments and penetration testing to validate the effectiveness of these controls and ensure ongoing compliance with NIST 800-171 Revision 3.

Phase 2 - A suggested method would be to include in your policy, a statement that you will identify, report, and correct system flaws in a timely manner. This should include regular vulnerability scanning and penetration testing, with defined timelines for remediation based on risk level. We should also implement robust configuration management processes to ensure systems are hardened and maintained in a secure state, including patching and updates. Furthermore, I believe we need to implement and monitor system logs to detect anomalies and potential security incidents, and establish incident response procedures to effectively handle any detected issues. Finally, we should ensure that all of these processes are documented, reviewed, and updated regularly to maintain their effectiveness and relevance.
