    Basically Query string in URL is the most important things that needs to be secure always
    To make them secure you can Encrypt and Decrypt QueryString Parameter Values in ASP.Net
    URL re-writing is also a good way to secure query string, Tamper Proof Query String is also one of the way to secure it, it first convert query string to byte and then using Base64String method to convert encrypt it
    see below urls to know more about it
