What is a brute force attack?

A brute force attack is the cyberattack equivalent of trying every combination on a combination lock and eventually finding the right one to open the lock. These types of attacks are simple and reliable and attackers let computers do all the work, trying different combinations of usernames and passwords until they find one that works.

The best defense against brute force attacks is increasing the password length and complexity, limiting the number of failed attempts allowed, implementing Captcha and implementing Multi-factor authentication.
