The Cisco ASA must be configured to filter outbound traffic, allowing only authorized ports and services.
High Severity
Information flow control regulates where information is allowed to travel within a network and between interconnected networks. Blocking or restricting detected harmful or suspicious communications between interconnected networks enforces approved authorizations for controlling the flow of traffic. The firewall that filters traffic outbound to interconnected networks with different security policies must be configured to permit or block traffic based on organization-defined traffic authorizations.
