JN0-231 Exam - Question 63


An application firewall processes the first packet in a session for which the application has not yet been identified.

In this scenario, which action does the application firewall take on the packet?

Show Answer
Correct Answer: A

In application firewall systems, packets are typically analyzed as they enter the system. The first packet in a session is allowed to pass through while the application identification engine processes it to determine the application. If the application is not yet identified, the initial packets are allowed, and more data is analyzed until the application can be accurately identified.

A is correct Application signatures identify an application based on protocol grammar analysis in the first few packets of a session. If the application identification engine has not yet identified the application, it passes the packets and waits for more data. https://www.juniper.net/documentation/us/en/software/junos/application-identification/topics/topic-map/security-application-identification-overview.html

When an application firewall encounters the first packet in a session for which the application has not yet been identified, the typical behavior would be to hold the first packet and subsequent packets until it can identify the application based on the data within the packets. Once the application is identified, the firewall then applies the appropriate rules or policies for that application.
