Redis Enterprise DBMS must limit privileges to change software modules; to include stored procedures, functions, and triggers, and links to software external to Redis Enterprise DBMS.
An XCCDF Rule
Description
<VulnDiscussion>If the system were to allow any user to make changes to software libraries, those changes might be implemented without undergoing the appropriate testing and approvals that are part of a robust change management process. Accordingly, only qualified and authorized individuals must be allowed to obtain access to information system components for purposes of initiating changes, including upgrades and modifications. Unmanaged changes that occur to the database software libraries or configuration can lead to unauthorized or compromised installations. For Redis Enterprise this is largely handled by the RHEL OS. The OS audit logs record any changes made to the database software libraries, related applications, and configuration files. Redis Enterprise also generates audit logs by default. All log entries are shown on the Log page in the Redis Enterprise web UI as well as written in the syslog. Only users in the admin role on the Redis Enterprise web UI and users with privileged access to the server can view, add, or remove modules. In both cases, this is logged.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Remediation - Manual Procedure
Implement procedures to monitor for unauthorized changes to DBMS software libraries, related software application libraries, and configuration files. If a third-party automated tool is not employed, an automated job that reports file information on the directories and files of interest and compares them to the baseline report for the same will meet the requirement. Syslog can be used to track and monitor access, deletions, and modification actions of the Redis logs, system configuration files, and binaries stored on the RHEL OS.
Ensure that the permissions of the Redis logs, system configuration files, and binaries are set so that only those with admin privileges can modify them on the hosting RHEL OS. Permissions can be modified using the chmod command.
