The audit information produced by Redis Enterprise DBMS must be protected from unauthorized deletion.
An XCCDF Rule
Description
<VulnDiscussion>If audit data were to become compromised, competent forensic analysis and discovery of the true source of potentially malicious system activity would be impossible to achieve. To ensure the veracity of audit data, the information system and/or the application must protect audit information from unauthorized deletion. This requirement can be achieved through multiple methods which will depend upon system architecture and design. Some commonly employed methods include: ensuring log files enjoy the proper file system permissions utilizing file system protections; restricting access; and backing up log data to ensure log data is retained. Applications providing a user interface to audit data will leverage user permissions and roles identifying the user accessing the data and the corresponding rights the user enjoys in order make access decisions regarding the deletion of audit data. Audit information includes all information (e.g., audit records, audit settings, and audit reports) needed to successfully audit information system activity. Deletion of database audit data could mask the theft of, or the unauthorized modification of, sensitive data stored in the database.</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
To investigate the log files used by Redis Enterprise, perform the following steps:
1. SSH into the server running Redis Enterprise.
2. Issue the command chmod 640 /var/opt/redislabs/log/* to change permissions of log files that are not appropriately assigned permissions.
3. Issue the command chown owner:group -R /var/opt/redislabs/log/ if the ownership is not correct where the owner and group are substituted for the appropriate owner and group.
Redis Enterprise provides configurable role-based access control inherently within the product. To ensure that users are provided the appropriate permissions that they are authorized to use, check each user's assigned roles.
