Symantec ProxySG must configure the maintenance and health monitoring to send an alarm when a critical condition occurs for a component.

Predictable failure prevention requires organizational planning to address device failure issues. If components key to maintaining the device's security fail to function, the device could continue operating in an insecure state. If appropriate actions are not taken when a network device failure occurs, a denial of service condition may occur which could result in mission failure since the network would be operating without a critical security monitoring and prevention function. Upon detecting a failure of network device security components, the network device must activate a system alert message or send an alarm.

The type of alarm should ensure that an administrator is made aware of the situation within a period specified in the site's SSP based on mission impact. Alarms may be a message send to an events server, SNMP server, email/text, or a monitored console.

The following alarms are required for ProxySG devices used in DoD.
General
* CPU utilization
* Memory utilization
