UBTU-16-010400 - All persistent disk partitions must implement cryptographic mechanisms to prevent unauthorized disclosure or modification of all information that requires at rest protection.


Ubuntu 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).

Satisfies: SRG-OS-000185-GPOS-00079, SRG-OS-000404-GPOS-00183, SRG-OS-000405-GPOS-00184

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.


Configure the Ubuntu operating system to prevent unauthorized modification of all information at rest by using disk encryption.

Encrypting a partition in an already-installed system is more difficult, because you need to resize and change existing partitions. To encrypt an entire partition, dedicate a partition for encryption in the partition layout.
