Ubuntu 22.04 LTS must implement cryptographic mechanisms to prevent unauthorized disclosure and modification of all information that requires protection at rest. An XCCDF Rule
Ubuntu 22.04 LTS must implement cryptographic mechanisms to prevent unauthorized disclosure and modification of all information that requires protection at rest.
Medium Severity
<VulnDiscussion>Operating systems handling data requiring "data at rest" protections must employ cryptographic mechanisms to prevent unauthorized disclosure and modification of the information at rest.
Selection of a cryptographic mechanism is based on the need to protect the integrity of organizational information. The strength of the mechanism is commensurate with the security category and/or classification of the information. Organizations have the flexibility to either encrypt all information on storage devices (i.e., full disk encryption) or encrypt specific data structures (e.g., files, records, or fields).
