US Patent 11956277 Zero network-profile cryptographically secure network port access

Systems and methods for protecting access to network ports on a server are provided herein. A system comprises a server configured to receive a data packet comprising a cryptoken corresponding to a network port address. The server is further configured to generate a plurality of cryptokens based on a plurality of timecodes, a network port configuration, and the destination address. The server generates a plurality of hashes based on the plurality of cryptokens. The server generates, based on a comparison of each of the plurality of cryptokens to the cryptoken, a rule to allow inbound connections to a first network port corresponding to the network port address.
