Information at rest refers to the state of information when it is located on a secondary storage device (e.g., disk drive and tape drive, when used for backups) within an operating system. This requirement addresses protection of user-generated data, as well as operating system-specific configuration data. Organizations may choose to employ different mechanisms to achieve confidentiality and integrity protections, as appropriate, in accordance with the security category and/or classification of the information. |

If the organization does not require to encrypt the data at rest this is Not Applicable. Check if the "clic.rte" fileset is installed: # lslpp -l |grep clic The above command should yield the following output: clic.rte.kernext 4.10.0.1 COMMITTED CryptoLite for C Kernel clic.rte.lib 4.10.0.1 COMMITTED CryptoLite for C Library clic.rte.kernext 4.10.0.1 COMMITTED CryptoLite for C Kernel If the "clic.rte" fileset is not installed, this is a finding. To check if a JFS2 file system (mounted as /fs2_mnt) is EFS-enabled, use the following command: # lsfs -q /fs2_mnt Name Nodename Mount Pt VFS Size Options Auto Accounting /dev/fslv00 -- /fs2_mnt jfs2 262144 -- no no (lv size: 262144, fs size: 262144, block size: 4096, sparse files: yes, inline log: no, inline log size: 0, EAformat: v2, Quota: no, DMAPI: no, VIX: yes, EFS: no, ISNAPSHOT: no, MAXEXT: 0, MountGuard: no) If the above command shows "EFS: no", this is a finding. |

Install "clic.rte" fileset if it is not installed using command: # installp -aXYqg -d /dev/cd0 clic.rte Run the follow command to initialize and enable EFS on the system: # efsenable -a To create a new EFS-enabled JFS2 file system and mount the file system, using the following commands: # crfs -v jfs2 -g rootvg -m /fs2 -a size=100M -a efs=yes # mount /fs2 To enable EFS on a JFS2 file system (like, /fs3), run the following command: chfs -a efs=yes /fs3 |
