Which of the following traffic is transmitted in the outbound direction for interzone packet filtering?

• A. Trusted zone -> Untrusted zone
• B. Untrusted zone -> Trusted zone
• C. Untrusted zone -> DMZ
• D. Trusted zone -> Local zone

Answer: (A)

The correct choice indicates the direction of traffic flow being discussed in the context of interzone packet filtering. In a network security architecture, trusted and untrusted zones represent different levels of security. When traffic is transmitted from a trusted zone to an untrusted zone, it is typically outbound for the trusted zone. The trusted zone is considered secure and controlled, often containing internal network resources or systems that have been vetted for security. On the other hand, an untrusted zone, such as the internet, poses various threats and potential vulnerabilities. When a device or application on the trusted zone initiates communication with an external environment (the untrusted zone), it is essential to implement appropriate interzone packet filtering to monitor and control this outbound traffic. This allows the organization to protect its resources by ensuring that only authorized traffic is allowed to leave the secure environment. The other scenarios involve different directions of traffic which do not align with the definitions of outbound traffic concerning interzone filtering in this context. Each of those choices represents either inbound traffic to a trusted zone or lateral traffic that does not signify a transition from a trusted zone to an untrusted zone.
