Unauthorized Service Request

Genian ZTNA can detect an unauthorized service requested in a variety of ways. The Network Sensor monitors the network traffic flow to check the access event of ports. If an unwanted service is requested on any virtual IP addresses, Genian ZTNA suspends the Unknown Service Request and designates the Node as a critical one. In addition, if the service requests are more than the specified value within a period of time, then designated as a critical Node.
