Description
The AIX Encrypted File System (EFS) is a J2 filesystem-level encryption through individual key stores. This allows for file encryption in order to protect confidential data from attackers with physical access to the computer. User authentication and access control lists can protect files from unauthorized access (even from root user) while the operating system is running. 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-000480-GPOS-00227, SRG-OS-000405-GPOS-00184, SRG-OS-000404-GPOS-00183

Who does this work

10 NICE work roles and 9 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-215283r1207664_chk)

If the organization does not require to encrypt the data at rest, this is Not Applicable. Check if "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.lib", or the "clic.rte.kernext", 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.

Fix Text (F-16479r1207663_fix)

Install "clic.rte" filesets from AIX DVD Volume 1 using the following commands (assuming that the DVD device is /dev/cd0): # installp -aXYgd /dev/cd0 -e /tmp/install.log clic.rte.lib # installp -aXYgd /dev/cd0 -e /tmp/install.log clic.rte.kernext Run the following 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
