SLES-15-010330 - All SUSE operating system persistent disk partitions must implement cryptographic mechanisms to prevent unauthorized disclosure or modification of all information that requires at-rest protection.
SUSE 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 provided the target output to assist in reviewing the benchmark to ensure target compliance.
Configure the SUSE 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 of the need to resize and change existing partitions. To encrypt an entire partition, dedicate a partition for encryption in the partition layout. The standard partitioning proposal as suggested by YaST (installation and configuration tool for Linux) does not include an encrypted partition by default. Add it manually in the partitioning dialog. Refer to the document 'SUSE Linux Enterprise Server 15 SP1 - Security Guide', Section 12.1.2, for a detailed disk encryption guide: https://documentation.suse.com/sles/15-SP1/html/SLES-all/cha-security-cryptofs.html#sec-security-cryptofs-y2-part-run
