1. A system for mitigating a threat associated with network data packets, the system comprising:
an authentication server configured to:
receive, from a gaming client, a request for access to a gaming server; and
authenticate the gaming client, the authentication including providing an authentication token to the gaming client; and
a mitigation device configured to:
receive, from the gaming client, at least one network packet directed to the gaming server, the at least one network packet embedding the authentication token;
validate authenticity of the authentication token; and
based on the validation, selectively forward the at least one network packet to the gaming server, wherein the authentication token is independently generated by the authentication server, the mitigation device, and the gaming server using a shared token generation algorithm based on a hash salt value.
