When beginning to understand the Zero Trust protect surface using the Palo Alto Networks Zero Trust reference architecture, the following two steps are crucial:

Validate User Identities through Authentication (A): This step involves ensuring that all users are authenticated properly. By verifying the identities of users attempting to access the network, organizations can ensure that only authorized users can access sensitive resources. This is a fundamental principle of Zero Trust, which operates on the premise of "never trust, always verify."

Categorize Data and Applications by Levels of Sensitivity (C): This involves identifying and classifying data and applications based on their sensitivity and importance to the organization. By understanding what needs to be protected and the level of sensitivity, security policies can be tailored to provide appropriate levels of protection. This helps in prioritizing security measures based on the criticality of the data and applications.

To support asymmetric routing with redundancy in a legacy environment using Palo Alto Networks firewalls, the following two features must be enabled:

Policy-based forwarding (PBF): This feature allows you to direct traffic to a specific interface or next-hop IP address, bypassing the normal routing table. PBF is crucial for managing asymmetric routing scenarios where inbound and outbound traffic might take different paths.

HA active/active: High Availability (HA) active/active configuration enables two firewalls to simultaneously manage traffic, providing redundancy and failover capabilities. This setup is essential for maintaining network availability and performance in environments with asymmetric routing, as it ensures that both firewalls can actively handle traffic.

Decryption Broker on a Next-Generation Firewall (NGFW) provides two primary benefits:

Offloading SSL decryption: The NGFW decrypts traffic once and then forwards it to multiple security devices for inspection, avoiding the need to decrypt and re-encrypt traffic multiple times, thus improving efficiency.

Reducing third-party devices: By handling SSL decryption within the NGFW, the need for separate, dedicated SSL decryption devices is eliminated, reducing the complexity and number of devices required for network security.

These features streamline traffic analysis and enforcement while maintaining robust security.
