Using an ACL to Restrict Mutual Access Between Network Segments

Using an ACL to Restrict Mutual Access Between Network Segments

Unrestricted mutual access between different network segments brings security risks. To restrict users' access to network segments on which they do not reside, you can apply an ACL to a traffic policy or simplified traffic policy.

In Figure 5-6, the financial department and the marketing department reside on separate network segments. Information leak may occur if the two departments have unrestricted access to each other. Therefore, to restrict mutual access between the two departments, an ACL-based traffic policy or simplified traffic policy is applied in the inbound direction of the interfaces (Interface 1 and Interface 2).
