Log records can be generated from various components within the application (e.g., process, module). Certain specific application functionalities may be audited as well. The list of audited events is the set of events for which audits are to be generated.
    SV-95831r1_rule SRG-APP-000090-AU-000070 CCI-000171 LOW The Central Log Server must be configured to allow only the Information System Security Manager (ISSM) (or individuals or roles appointed by the ISSM) to select which auditable events are to be retained. Without restricting which roles and individuals can select which events are audited, unauthorized personnel may be able to prevent the auditing of critical events. Misconfigured audits may degrade the system's performance by overwhelming the audit log. Mi

The ability to specify the event criteria that are of interest provides the persons reviewing the logs with the ability to quickly isolate and identify these events without having to review entries that are of little or no consequence to the investigation
    SV-95837r1_rule SRG-APP-000116-AU-000270 CCI-000159 LOW The Central Log Server must be configured to use internal system clocks to generate time stamps for log records. Without an internal clock used as the reference for the time stored on each event to provide a trusted common reference for the time, forensic analysis would be impeded. Determining the correct time a particular event occurred on a system is critical when
