Abstract

Methods, non-transitory computer readable media, network traffic manager apparatuses, and systems that assist with mitigating DDoS attack using a hardware device includes determining when a received network packet in an established connection between a client and a destination server includes a connection identifier cookie. A connection validation cookie is generated based on at least data in the received network packet, when the determination indicates the received network packet includes the connection identifier cookie. The connection identifier cookie is compared against the generated connection validation cookie. The received network packet is dropped when the comparison indicates the connection validation cookie fails to match the connection identifier cookie.
