SSH attack with hydra and sshd config

Anyone know how to protect a server succumbing
to brute force via hydra? The sshd_conf has maximum retries as 6; so when I manually try to login with deliberately wrong password then, the sessions stops mentioning “too many authentication error” but with hydra even after 30+ iterations, it succeeds. My question what do I need to modify on sshd_conf file to prevent ssh brute forcing from hydra?
