- لاگین با حساب root رو غیر فعال کنید.
- حساب خودتون رو تنظیم کنید تا با کلید نامتقارن بشه لاگین کرد.
- لاگین با پسورد رو در SSH ببندید.
- پورت دیگه‌ای رو در فایروال ابتدا باز کنید.
- SSH رو تنظیم کنید تا روی پورت جدیدی که باز کردید Listen کنه.
- یک Honeypot بزارید روی پورت 22 تا وقت بات‌ها رو تلف کنه.
* می‌تونید از ابزارهایی مثل Fail2Ban هم استفاده کنید.
