Abstract

Systems and methods for network traffic monitoring are provided. A system may obtain a data packet of a data packet exchange between the server and a network device, extract a time to live (TTL) value and an internet protocol (IP) address of the network device from the data packet, compare the TTL value with a TTL value range or signature determined based on TTL values observed from data packets transmitted across a communications network, determine that the TTL value violates an authentication policy based on the TTL value being outside of the TTL value range or signature, and apply a tag to the IP address of the network device in a database stored memory.
