AU-2Event Logging
Identify the types of events that the system is capable of logging in support of the audit function: {{ insert: param, au-02_odp.01 }}; Coordinate the event logging function with other organizational entities requiring audit-related information to guide and inform the selection criteria for events to be logged; Specify the following event types for logging within the system: {{ insert: param, au-2_prm_2 }}; Provide a rationale for why the event types selected for logging are deemed to be adequate to support after-the-fact investigations of incidents; and Review and update the event types selected for logging {{ insert: param, au-02_odp.04 }}.

Weaknesses this control addresses (1)AI
CWEs ranked by how often they appear in real CVEs. The rationale describes how this control reduces exploitability of each weakness class.
| CWE | Name | CVEs | Why this control addresses it |
|---|---|---|---|
CWE-778 | Insufficient Logging | 25 | This control requires identifying, specifying, and justifying event types for logging with a focus on adequacy for post-incident investigations, directly mitigating insufficient logging. |
