System and method for leak prevention for domain name system requests

A system for DNS resolution, comprising:

• a processor;
• a non-transitory computer readable medium, comprising instructions for:
• configuring an operating system at a client device in association with a DNS protection agent installed locally at the client device;
• detecting, by the DNS protection agent at a port of the client device associated with a DNS security protocol, a first DNS request generated by an application executing on the client device, the first DNS request designating an Internet resource and associated with a DNS resolver;
• filtering, using the DNS protection agent, the first DNS request associated with the DNS resolver;
• receiving, at the DNS protection agent, a second DNS request from the application, wherein the second DNS request was directed to the DNS protection agent according to the configuration of the operating system at the client device;
• sending, using the DNS protection agent, the redirected DNS request to the DNS protection server to resolve the Internet address;
• receiving a response from the DNS protection server at the DNS protection agent;
• and
• forwarding the response to the application on the client device.
