Description
Redis Enterprise does not send immediate real-time alerts to support staff in the event of audit log failures; however, the host RHEL server can be configured to send such alerts using scripts or other third-party tools. It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required. Without a real-time alert, security personnel may be unaware of an impending failure of the audit capability, and system operation may be adversely affected. The appropriate support staff include, at a minimum, the ISSO and the DBA/SA. A failure of database auditing will result in either the database continuing to function without auditing or in a complete halt to database operations. When audit processing fails, appropriate personnel must be alerted immediately to avoid further downtime or unaudited transactions. Alerts provide organizations with urgent messages. Real-time alerts provide these messages immediately (i.e., the time from event detection to alert occurs in seconds or less).

Review the OS or third-party logging software settings to determine whether a real-time alert will be sent to the appropriate personnel when auditing fails for any reason. If real-time alerts are not sent upon auditing failure, this is a finding.

Fix Text (F-54587r804783_fix)
Configure the system to provide an immediate real-time alert to appropriate support staff when an audit log failure occurs. It is possible to create scripts or implement third-party tools to enable real-time alerting for audit log failures, depending on the underlying OS. Additionally, it is recommended to enable the following alerts from within the Redis Enterprise AdminUI Console: 1. Log in to the AdminUI. 2. Navigate to settings >> alerts. - Receive email alerts (with the appropriate email server settings configured under settings >> general) - Node has sufficient disk space for AOF rewrite - Multiple nodes are down - this may cause data loss
