Unrestricted traffic may contain malicious traffic which poses a threat to an enclave or to other connected networks. Additionally, unrestricted traffic may transit a network, which uses bandwidth and other resources. VPN traffic received from another enclave with different security policy or level of trust must not bypass be inspected by the firewall before being forwarded to the private network.

1. Network.

5. Verify that "ESP" is selected in the IPsec Protocol section.

If the BIG-IP is not configured to ensure inbound and outbound traffic is configured with a security policy in compliance with information flow control policies, this is a finding.
