    Project mention: Breaking the 300 barrier | | 2024-02-21

  • Rack::Attack

    Rack middleware for blocking & throttling

    Project mention: Rails Authentication for Compliance | | 2023-10-28

    The first line of defense should be to put rate-limiting on your login endpoints. rack-attack can help with that. I recommend to limit the login attempts to 5 per minute for a username and block the IP for 30 minutes. You should also limit the number of login attempts from the same IP address, but this needs to be adjusted to the application you are working on, because if it is a tool used in classrooms, it might be legit to have 50 logins within a few minutes from the same IP. (I have a few post written about rack-attack)
