Protection of Data at Rest
PR.DS-01: The confidentiality, integrity, and availability of data-at-rest are protected
  • Ex1:  Use encryption, digital signatures, and cryptographic hashes to protect the confidentiality and integrity of stored data in files, databases, virtual machine disk images, container images, and other resources
  • Ex2:  Use full disk encryption to protect data stored on user endpoints
  • Ex3:  Confirm the integrity of software by validating signatures
  • Ex4:  Restrict the use of removable media to prevent data exfiltration
  • Ex5:  Physically secure removable media containing unencrypted sensitive information, such as within locked offices or file cabinets
Tier
Not Applicable - Not applicable
No - The outcome(s) have not been meaningfully implemented.
Tier 1: Partial - Application of the organizational cybersecurity risk strategy is managed in an ad hoc manner. Prioritization is ad hoc and not formally based on objectives or threat environment.
Tier 2: Risk Informed - Risk management practices are approved by management but may not be established as organization-wide policy. The prioritization of cybersecurity activities and protection needs is directly informed by organizational risk objectives, the threat environment, or business/mission requirements.
Tier 3: Repeatable - The organization’s risk management practices are formally approved and expressed as policy. Risk-informed policies, processes, and procedures are defined, implemented as intended, and reviewed. Organizational cybersecurity practices are regularly updated based on the application of risk management processes to changes in business/mission requirements, threats, and technological landscape.
Tier 4: Adaptive - There is an organization-wide approach to managing cybersecurity risks that uses risk-informed policies, processes, and procedures to address potential cybersecurity events.
