The SA must configure the firewall for the minimum content and protocol inspection requirements.
Overview
| Finding ID | Version | Rule ID | IA Controls | Severity |
|---|---|---|---|---|
| V-14643 | NET0366 | SV-15269r2_rule | Medium |
| Description |
|---|
| Creating a filter to allow a port or service through the firewall without content or protocol inspection creates a direct connection between the host in the private network and a host on the outside; thereby, bypassing additional security measures that could be provided. This places the internal host at a greater risk of exploitation that could make the entire network vulnerable to an attack. |
