Discussion

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). Satisfies: SRG-APP-000360-NDM-000295, SRG-APP-000795-NDM-000130

Check Content

Determine if the Cisco SNA appliance is configured to generate an immediate alert of all audit failure events requiring real-time alerts.

Navigate to SNA Dashboard >> Configure >> Central Management >> Actions... >> Edit Appliance Configuration >> General Tab >> SMTP Configuration.

Verify an SMTP server is configured (e.g., port, From Email, User Name, Password and Encryption Type).

Navigate to SNA Dashboard >> Configure >> Central Management >> Actions... >> Edit Appliance Configuration >> General Tab >> DODIN Notifications.

Verify "DODIN Notifications" is "Enabled" and sent to an appropriate email address.

If an immediate alert of all audit failure events requiring real-time alerts is not generated, this is a finding.
