The Cisco ASA must be configured to generate an immediate real-time alert of all audit failure events requiring real-time alerts.
Overview
| Finding ID | Version | Rule ID | IA Controls | Severity |
| V-239923 | CASA-ND-000930 | SV-239923r991812_rule | CCI-001858 | medium |
| Description | ||||
| 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. 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 Cisco ASA configuration to verify it is compliant with this requirement as shown in the example below.
logging trap critical
logging host NDM_INTERFACE 10.1.48.10
Note: The parameter critical can replaced with a lesser severity (i.e., error, warning, notice, informational). A logging list can be used as an alternative to the severity level.
If the Cisco ASA is not configured to generate an alert for all audit failure events, this is a finding.
Fix Text (F-43115r666131_fix)
Configure the Cisco ASA to send critical to emergency log messages to the syslog server as shown in the example below.
ASA(config)# logging host NDM_INTERFACE 10.1.48.10
ASA(config)# logging trap critical
ASA(config)# end
Note: The parameter critical can replaced with a lesser severity (i.e., error, warning, notice, informational).
