The following summarizes the recommneded security standards and requirements for protecting highly confidential information when it is processed, stored, or transmitted. The checklist is meant as a guide to help users overview each of the categories necessary for keeping highly confidential information protected. If all boxes can be checked, all highly confidential information is consided to meet the minimum security requirements of protection. 

Control Family Summary
Access Control Limit system access of systems to authorized users by separating individual duties and monitoring remote access. Control, monitor, and encrypt highly confidential information on all platforms, including remote devices, and systems to control the flow of highly confidential information.
Awareness and Training To ensure that users, managers, and system administrators are properly trained and aware of their security impact associated with their activity within organizational systems.
Audit and Accountability Keep track of system activity by establishing and maintaining accurate and up to date audit logs and records in case of unlawful system activity.
Configuration Management Establish base configurations that control and monitor access and use of software, hardware, firmware, and documentation in organizational systems.
Identification and Authentication Have multifactor authentication mechanisms to access networks by enforcing proper passwords and verifications of users between privileged and non-privileged accounts.
Incident Response Establish and test incident handling responses for organizational systems and keep documentation of incidents of the systems.
Maintenance  Perform maintenance on organizational systems by providing controls, sanitizing equipment, checking media for malicious code, requiring authentication for nonlocal maintenance, and supervising maintenance activity and personnel.
Media Protection Protect highly confidential information on both digital and paper media during transport, in storage, and before disposal.
Personnel Security Ensure that organizational systems containing highly confidential information are protected prior to, during, and after individuals have access. 
Physical Protection Protect and monitor physical access to the organizational system and its operating environments.
Risk Assessment Assess the risk to organizational systems from associated processing storage, or transmission of highly confidential information. This includes periodically scanning for vulnerabilities and applications and remediating them once found.
Secuirity Assessment Ensure that the security controls in organizational systems are working properly and have plans in place to properly describe how systems are operated, implemented, and connected to other systems, as well as eliminate and correct deficiencies.
System and Communications Protection Protect highly confidential information by monitoring, controlling, and protecting communication within the organizational system. This is excecuted by using cryptographic mechanisms, monitoring remote access, monitoring user activity and communication, and controlling network connections associated with communication.
System and Information Integrity Protect organizational systems from malicious code and potential attacks by regularly scanning files, especially when external sources are executed, as well as monitoring communication and unauthorized use of the organizational systems.
