A network security team is designing a new segment of their network that will host critical applications. They need to ensure that traffic between this segment and other internal segments is strictly controlled based on the exact application being used, and that no unauthorized applications can traverse the boundary. Which Palo Alto Networks feature is fundamental to achieving this granular control?
- AApp-ID
- BGlobalProtect
- CURL Filtering
- DUser-ID
Show answer & explanationAnswer & explanation
Correct answer: A. App-ID
App-ID is the patented technology that identifies applications traversing the firewall, regardless of port, protocol, or evasive tactics. This allows security policies to be based on the actual application, providing granular control and preventing unauthorized applications from running on permitted ports.
Why the other options are wrong
- B. GlobalProtect provides secure remote access, unrelated to granular application control on internal segments.
- C. URL Filtering controls access to websites, not specific applications.
- D. User-ID identifies users and groups, but App-ID identifies the application itself.
App-ID
Palo Alto Networks' patented technology that identifies applications traversing the firewall, regardless of port, protocol, or evasive techniques, enabling application-specific security policies.
- Identifies applications (not just ports)
- Enables application-based security policies
- Crucial for granular control and threat prevention
Memory trick: App-ID sees the true app, no matter the port trap.
