New in Symfony 5.2: Login Throttling
A common brute-force attack against web applications consists of an attacker submitting a login form many times with the hope of eventually guessing the password of some user account.
One of the best countermeasures to these attacks is called “login throttling”, which denies a user from attempting logins after a certain number of failed attempts. Thanks to the recently added RateLimiter component, Symfony 5.2 will provide login throttling out of the box.
First, make sure that you are using the new Authenticator-based Security. Then, add the following configuration to your firewall:
1 2 3 4 5 6 7 8 9 10 11 12 13 14
# config/packages/security.yaml security: firewalls: default: # by default, the feature allows 5 login attempts per minute login_throttling: ~ # configuring the maximum login attempts (per minute) login_throttling: max_attempts: 1 # you can even use a custom rate limiter via its service ID login_throttling: limiter: app.my_login_rate_limiter
That’s all. Next time an attacker tries to make too many login attempts, your Symfony application will start blocking them.
