PUSH floods and ACK floods are denial of service attacks based on the PSH and ACK flags.

Since these flags require additional processing it may be possible to overwhelm a service by setting these flags on numerous requests.

Mitigation[edit]

Proxy filters may drop appropriate packets with these flags set when the system is considered to be under attack.^{[1][failed verification]}
