security overview
This port should generally be allowed only according to the host's Delivery Optimization policy and should not be deliberately exposed or port-forwarded to the Internet. It is not a remote administration interface, but an exposed peer service can disclose or consume update-distribution traffic and increases attack surface; restrict it with the host firewall and network policy.
