Replay attack is a type of attack that may happen in the TCP/IP network. To perform a replay attack, the attacker must first capture an amount of sensitive traffic, then simply replay it back to the host in an attempt to replicate the transaction. This attack may also cause target connection to drop. The random TCP sequence numbers and encyption like SSH and IPsec can help reduce the risk of this type of attack.
