  • Systems and methods of controlling internet access using encrypted DNS
    Patent number: 11831602
    Abstract: Described systems and methods enable protecting client devices (e.g., personal computers and IoT devices) implementing encrypted DNS protocols against harmful or inappropriate Internet content. A DNS proxy intercepts an attempt to establish an encrypted communication session between a client device and a DNS server. Without decrypting any communications, some embodiments of the DNS proxy determine an identifier of the respective session and an identifier of the client device, and send a query tracer connecting the session identifier with the client identifier to a security server. In some embodiments, the security server obtains the domain name included in an encrypted DNS query from the DNS server and instructs the DNS server to allow or block access of the client device to the respective Internet domain according to a device- and/or user-specific access policy.
