3. Audit and Accountability (AU): Features that track and examine activity within the system.
4. Security Assessment and Authorization (CA): Processes to assess risks and authorize system operation.
5. Configuration Management (CM): Management of security features and assurances through control of changes to hardware, software, firmware, and documentation.
6. Contingency Planning (CP): Plans and preparations for emergency response, backup operations, and post-disaster recovery.
7. Identification and Authentication (IA): Ensuring that only authorized individuals can access the system.
8. Incident Response (IR): Preparedness to handle and respond to security incidents.
9. Maintenance (MA): Processes for maintaining the security of and repairing information systems.
10. Media Protection (MP): Measures to protect digital and physical media containing sensitive information.
11. Physical and Environmental Protection (PE): Protections for the physical facility and its resources.
12. Personnel Security (PS): Ensuring that individuals with access to systems are trustworthy and meet security criteria.
13. Risk Assessment (RA): Assessing security risks to guide protective measures.
14. System and Services Acquisition (SA): Processes to ensure that purchased systems and services meet security requirements.
15. System and Communications Protection (SC): Protecting communications and operations of information systems.
16. System and Information Integrity (SI): Ensuring information system resources are operating correctly and free from unauthorized changes or corruption.

These controls are applicable in various contexts and can be tailored based on the specific security requirements of the organization or system. They are integral to establishing a secure IT infrastructure and managing cybersecurity risks effectively.
