Title

The Cisco ASA must be configured to send an alert to organization-defined personnel and/or the firewall administrator when threats are detected. (Cat II impact)

Discussion

Without an alert, security personnel may be unaware of an impending failure of the audit capability, and the ability to perform forensic analysis and detect rate-based and other anomalies will be impeded. Alerts may be transmitted, for example, telephonically, by electronic mail messages, or by text messaging. The IDPS must either send the alert to a management console that is actively monitored by authorized personnel or use a messaging capability to send the alert directly to designated personnel. The ISSM or ISSO may designate the firewall administrator and/or other authorized personnel to receive the alert within the specified time, validate the alert, and then forward only validated alerts to the ISSM and ISSO.

Verify email server and email addresses have been defined. Step 1: Navigate to Policies >> Actions >> Alerts. Step 2: From the Create Alert drop-down menu, choose Create Email Alert. Step 3: Verify that the email address is that of organization-defined personnel and/or the firewall administrator. If the Cisco ASA is not configured to send an alert to organization-defined personnel and/or firewall administrator when threats are detected, this is a finding.
