The Cisco ASA must be configured to produce audit log records containing information to establish the source of events.

In order to compile an accurate risk assessment and provide forensic analysis, it is essential for security personnel to know the source of the event. The source may be a component, module, or process within the device or an external session, administrator, or device.

Associating information about where the source of the event occurred provides a means of investigating an attack; recognizing resource utilization or capacity thresholds; or identifying an improperly configured device.

Review the Cisco ASA configuration to verify that it is compliant with this requirement. The configuration should look similar to the example below:

logging enable logging buffered informational

Note: The ASA will log location (IP address or console) from where configuration commands are entered.

If the ASA is not configured to generate audit records containing information to establish the source of events, this is a finding.

Configure the Cisco ASA as shown in the example below.

ASA(config)# logging enable ASA(config)# logging buffered informational ASA(config)# end
