The ALG providing content filtering must generate an alert to, at a minimum, the ISSO and ISSM when user level intrusions which provide non-privileged access are detected.

Description
Without an alert, security personnel may be unaware of major detection incidents that require immediate action and this delay may result in the loss or compromise of information. The ALG generates an alert which notifies designated personnel of the Indicators of Compromise (IOCs) which require real-time alerts. These messages should include a severity level indicator or code as an indicator of the criticality of the incident. These indicators reflect the occurrence of a compromise or a potential compromise. Since these incidents require immediate action, these messages are assigned a critical or level 1 priority/severity, depending on the system's priority schema. CJCSM 6510.01B, "Cyber Incident Handling Program", lists nine Cyber Incident and Reportable Event Categories. DoD has determined that categories identified by CJCSM 6510.01B Major Indicators (category 1, 2, 4, or 7 detection events) will require an alert when an event is detected. Alerts may be transmitted, for example, telephonically, by electronic mail messages, or by text messaging. The ALG 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.

Check Text ( C-55303r1_chk )
If the ALG does not perform content filtering as part of the traffic management functions, this is not applicable.

Verify the ALG generates an alert to, at a minimum, the ISSO and ISSM when user level intrusions which provide non-privileged access are detected.

If the ALG does not generate an alert to, at a minimum, the ISSO and ISSM when user level intrusions which provide non-privileged access are detected, this is a finding.
Fix Text (F-59539r1_fix)
If the ALG performs content filtering as part of the traffic management functionality, configure the ALG to generate an alert to, at a minimum, the ISSO and ISSM when user level intrusions which provide non-privileged access are detected.
