The mobile operating system must be able to filter both inbound and outbound traffic based on IP address and UDP/TCP port.

| Description |
|---|
| Open ports provide an attack surface that an adversary can then potentially use to breach system security. If an adversary can communicate with the mobile device from any IP address, then the device may be open to any other device on the Internet. Reducing the attack surface through IP address and port restrictions mitigates this risk. |
