Brute Force Attack is a method of finding the right credentials by repetitively trying all the permutations and combinations of possible credentials. Brute Force Attacks are automated in most cases where the tool/software automatically tries to log in with a list of possible credentials.
Following is a list of some ways to prevent Brute Force Attacks :
Password Length : The length of a password is an important aspect to make it hard to crack. You can specify to set at least a minimum length for the password. The lengthier the password, the harder it is to find.
Password Complexity : You can include different characters formats in the password to make brute force attacks harder. Using the combination of alpha-numeric keywords along with special characters and upper and lower case characters can increase the password complexity making it difficult to be cracked.
Limiting Login Attempts : You can make the password hard for brute force attacks by setting a limit on login failures. For example, you can set the limit on login failures as 5. So, when there are five consecutive login failures, the system will restrict the user from logging in for some time or send an Email or OTP to log in the next time. Because brute force is an automated process, limiting login attempts will break the brute force process.
