Control

Extent to which protective measures, techniques, and procedures must be applied to information systems and networks based on risk, threat, vulnerability, system interconnectivity considerations, and information assurance needs. Levels of protection are: 1. Basic: information system and networks requiring implementation of standard minimum security countermeasures. 2. Medium: information system and networks requiring layering of additional safeguards above the standard minimum security countermeasures. 3. High: information system and networks requiring the most stringent protection and rigorous security countermeasures.

Actions taken to patch a vulnerability or secure a system against an attack. Countermeasures can include altering access controls, reconfiguring security settings, installing new security devices or mechanisms, adding or removing services, and so on.

Security controls (i. e. , safeguards or countermeasures) for an information system that are primarily implemented and executed by the information system through mechanisms contained in the hardware, software, or firmware components of the system. (NIST Special Pub 80053. )The security controls (i. e. , safeguards or countermeasures) for an information system that are primarily implemented and executed by the information system through mechanisms contained in the hardware, software, or firmware components of the system.
[view]

Protective measures prescribed to meet the security requirements (i. e. , confidentiality, integrity, and availability) specified for an information system. Safeguards may include security features, management constraints, personnel security, and security of physical structures, areas, and devices. Synonymous with security controls and countermeasures.
