The Zero Trust model relies on the principle of "never trust, always verify" and includes continuous verification based on real-time data. According to SCAZT Section 1 (Cloud Security Architecture, Pages 14-
17), user and device behavior are key elements for continuous verification. Behavioral analytics evaluates deviations from typical activity, such as time of login, geolocation, access frequency, and resource usage to adapt trust levels dynamically. This is central to adaptive access control and risk-based authentication.

To enable VPN load balancing with secure encryption between Cisco ASA firewalls, two additional commands are required:
encryption aes 256: Defines the encryption scheme used in the load balancing cluster. Without specifying encryption, secure key exchanges between devices will not occur properly.
cluster encryption: Enables encrypted communication between the clustered ASA devices. Without this command, cluster member synchronization is not securely established.
The commands shown in the exhibit correctly configure the cluster key and virtual IP but lack the necessary encryption parameters. According to Cisco's VPN load balancing implementation guides and reinforced in the SCAZT documentation, these two settings are required to secure the VPN session load distribution.
