What is required for centralized security management as per the Palo Alto Networks system?

Centralized security management in the context of Palo Alto Networks is accomplished through the use of Panorama. Panorama is a management tool that allows for the centralized control of multiple Palo Alto Networks firewalls and security devices from a single interface. It provides a unified view of the security environment, enabling network and security administrators to manage policies, monitor logs, and deploy configurations across all connected devices efficiently.

With Panorama, organizations benefit from streamlined operations, consistent security policies, and improved visibility across their network infrastructure. This capability is essential for large enterprises or organizations with distributed networks, as it simplifies the complexities of managing numerous security appliances individually. Additionally, Panorama supports features such as centralized logging, reporting, and the orchestration of security updates, which are critical for maintaining a robust security posture.

The other options do not provide the same level of centralized management functionality as Panorama, hence they are not suitable for this purpose.
