Check Text ( C-54682r804929_chk )
Review the permissions granted to users by the operating system/file system on the database files, database log files, and database backup files.

If any user/role who is not an authorized system administrator with a need to know or database administrator with a need to know, or a system account for running DBMS processes, is permitted to read/view any of these files, this is a finding.

Review the directory contents and files and verify that the appropriate file permissions are set. Verify that the file owner and group is set to Redis Labs or a group defined per site requirements.

To check permissions of log files (Note: This may vary depending on the installation path.):
# /var/opt/redislabs/log

To check persisted files from memory if they are being used run the following command (Note: This may vary depending on the installation path.)
# ls -ltr /var/opt/redislabs/persist/redis/

To check the default file permissions to verify that all authenticated users can only read and modify their own files:
# cat/etc/login.defs|grep UMASK

Verify the value is set to 077 or an appropriate organizationally defined setting.

Investigate the permissions on these files. If the permissions allow access by other, this is a finding.
Fix Text (F-54636r804930_fix)
Configure the operating system to define default permissions for all authenticated users in such a way that the user can only read and modify their own files.

Add or edit the line for the "UMASK" parameter in "/etc/login.defs" file to "077":


Set the permissions of the log files (/var/opt/redislabs/log) and persisted files (/var/opt/redislabs/persist/redis/) to an appropriate organizationally defined setting.
