An Infrastructure ACL (iACL) is a security mechanism that is used to protect the network infrastructure from unauthorized access or malicious traffic. It is essential to have an iACL in place to prevent attackers from gaining unauthorized access to the network, stealing sensitive information, or disrupting the network services.
When configuring an iACL to protect the IPv6 infrastructure of an enterprise network, the iACL should be applied to all infrastructure devices in both the inbound and outbound directions. Therefore, option A is the correct answer.
The reason for this is that an iACL should be applied at the entry points to the network infrastructure, which are typically the border routers, switches, or firewalls. By applying the iACL in both the inbound and outbound directions, you can ensure that all traffic entering or leaving the network infrastructure is inspected and filtered according to the security policies.
If the iACL is applied only in the inbound direction, it will only filter traffic that is coming into the network infrastructure but will not filter traffic leaving the infrastructure. This leaves the network vulnerable to attacks that exploit weaknesses in the outbound traffic.
Similarly, if the iACL is applied only in the outbound direction, it will only filter traffic that is leaving the network infrastructure but will not filter traffic coming into the infrastructure. This leaves the network vulnerable to attacks that exploit weaknesses in the inbound traffic.
Parameter devices are typically end-user devices such as PCs, laptops, and mobile devices that are connected to the network. iACLs are not typically applied to parameter devices because they are not part of the network infrastructure.
In summary, when configuring an iACL to protect the IPv6 infrastructure of an enterprise network, the iACL should be applied to all infrastructure devices in both the inbound and outbound directions to ensure that all traffic entering or leaving the network infrastructure is inspected and filtered according to the security policies.
