1. A method of operating a computing system to facilitate protection of data resources from unauthorized access, the method comprising:
assigning, to an authorized user that is authorized to access a data resource, a unique port number on a data shield server that is associated with the data resource;
instructing the authorized user to replace an address and a port associated with the data resource with an updated address associated with the data shield server and the unique port on the data shield server that is uniquely assigned to the authorized user, wherein the authorized user is assigned a different unique port for each data resource said user is authorized to access;
receiving a request from a user to access the data resource at the updated address associated with the data shield server and on the unique port that is uniquely assigned to the authorized user;
in response to the request, authenticating the user using multi-factor authentication to verify that an identity of the user that submitted the request matches the authorized user assigned to the unique port on which the request was received; and
upon successful authentication, operating as a proxy to connect the user through to the data resource.
