5.1 Security Considerations for Implementers

The Microsoft Extensions to the DLNA Guidelines do not introduce any changes that affect security. Thus, the same security considerations that apply to the DLNA Guidelines also apply to implementations of the Microsoft Extensions to the DLNA Guidelines.

For details about security considerations for the DLNA Guidelines, see [RFC2616] section 15 and [RFC2326] section 16. Note that UPnP, HTTP and RTSP traffic is sent in cleartext, and the HTTP and RTSP protocols are used without any access authentication. Implementations can be secured to some extent by employing security mechanisms at the network and link layers, such as firewalls and WPA or WEP encryption for Wi-Fi networks, if applicable.
