Fix Recommendation

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

Check Contents

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.
