A region based firewall for A72SS0 integrated in its AXI2VBUSMC bridge is present in COMPUTE_CLUSTER0. This firewall protects the traffic generated from the A72SS0 and is placed on the master port side unlike most device firewalls that are on the slave port side. This firewall has to be programed to enable the A72 master port access to the needed slaves.
The A72SS0 region based firewall is same as the other device region based firewalls. For more information about their functionality, see Section 3.3.4Interconnect Firewalls in Chapter 3System Interconnect.
