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 incorporates a comprehensive cybersecurity awareness and training program to address NIST 800-171 Revision 3's "Awareness and Training" requirements. This program should mandate annual cybersecurity training for all personnel with access to CUI, covering proper handling procedures, individual responsibilities in protecting CUI, and current threat landscape awareness. We should also include role-based training tailored to specific job functions and system access levels, ensuring everyone understands their unique obligations. Furthermore, the policy should stipulate regular refresher training and ongoing awareness campaigns to reinforce best practices and keep our team informed of evolving threats and vulnerabilities. Finally, I believe the policy should outline clear consequences for failing to comply with training requirements and security protocols, demonstrating our commitment to protecting CUI.

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 1 - A suggested method would be to include in your policy, a statement that explicitly defines a configuration management process that adheres to NIST 800-171 Revision 3, Family Control CM. This process should detail how we establish and maintain secure configurations for all systems and software handling CUI. Specifically, it needs to outline procedures for baselining systems, continuously monitoring those configurations for vulnerabilities, and implementing a controlled change management process. This change management process should include impact analysis, approval workflows, and documentation of all changes. Crucially, the policy must mandate that all security configurations align with our organization's overall security policy and meet the federal requirements for protecting CUI, ensuring consistency and compliance.

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 comprehensive incident response plan that aligns with NIST 800-171 Revision 3, focusing specifically on protecting Controlled Unclassified Information (CUI). This policy should detail procedures for incident planning, detection, analysis, containment, eradication, recovery, and ongoing monitoring. It needs to clearly define roles and responsibilities, establish communication protocols, and outline steps for documenting incidents. Furthermore, the policy should include regular training for personnel on incident response procedures and emphasize the importance of continuous improvement through post-incident reviews and updates to the policy itself. This will help ensure we're prepared to effectively handle any security incidents involving CUI and minimize their impact.

Phase 1 - A suggested method would be to include in your policy, a statement that outlines specific procedures for maintaining systems processing CUI. This should detail how we securely perform maintenance, including patching, upgrades, and repairs. We need to establish strict controls over who can access and use maintenance tools, perhaps through a multi-factor authentication system and regular audits. Crucially, the policy should emphasize adherence to our existing configuration management plan, ensuring that any changes made during maintenance are documented, reviewed, and approved. This will help us prevent unauthorized modifications and maintain the confidentiality and integrity of CUI during all maintenance activities.

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.
