Discussion

Without an alert, security personnel may be unaware of intrusion detection incidents that require immediate action and this delay may result in the loss or compromise of information. In accordance with CCI-001242, the IDPS is a real-time intrusion detection system. These systems must generate an alert when detection events from real-time monitoring occur. 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 Juniper SRX IDPS can be configured for email alerts.

Verify an attack group or rule is configured.

If an attack group or rule is not implemented to detect root-level intrusion attacks or the match condition is not configured for an alert, this is a finding.

Fix Text

Create a custom rule that identifies the Junos application which is prohibited on the network. 

Add the option "alert" onto the rule to send an alert when that rule is invoked. Alerts should be sent only on critical and other site-selected items to prevent an excess of alerts.
