# Brute Force Attack - WHAT IS IT AND HOW TO PREVENT IT! - PowerPoint PPT Presentation

1 / 8

A Brute Force Attack is the simplest method to gain access to a site or server (or anything that is password protected). It tries various combinations of usernames and passwords until it gets in. This repetitive action is like an army attacking a fort.

## Brute Force Attack

WHAT IS IT AND HOW TO PREVENT IT!

### What is a Brute Force Attack?

• A Brute Force Attack is the simplest method to gain access to a site or server (or anything that is password protected).

• It tries various combinations of usernames and passwords until it gets in. This repetitive action is like an army attacking a fort.

### How it is done?

• Every common ID (for e.g. “admin”) has a password. All you need to do is try to guess the password. Simple, isn’t it?

• Well, not really!

• Let’s say if it’s a 4-digit-pin, you have 10 numeric digits from 0 to 9. This means there are 100 possibilities.

• You can figure this out with pen and paper like Mr. Bean did in the movie, Mr. Bean’s Holiday.

• But, the truth is that no password in the world consists of only 4 characters.

### How it is done?

• Let’s say if we have an alphanumeric 8-character password.

• We can have 52 possible alphabetic (normal + UPPER & Lower) combinations

• Now add the Numeric digits, i.e. 10.

• So, we have 62 characters in total.

• For 8-character-password, it will be 628 which will make 2.1834011×1014 possible combinations.

• If we attempt 218 trillion combinations at 1 try per second, it would take 218 trillion seconds or 3.6 trillion minutes, or at most, around 7 million years to crack the password.

### Then, How Can It Happen?

• If you are interested in cracking passwords, you will have to use computers and write a few basic codes.

• But a normal computer won’t do. You would need a supercomputer.

• After almost 1x109 attempts per second, after 22 seconds, You should be able to break an 8 character password.

• Computing resources of this kind are not available to common people. But hackers are not common people.

### That’s Scary! What to do Now?

• It is essential to have additional layers of security in order to detect and deflect any password breaching attempt.

• There are many tools available for securing different applications which deny a user after a predefined number of attempts.

• For example, for SSH we can use Fail2ban or Deny hosts.

### How To Prevent It?

• Take these precautionary measures to prevent attacks:

• Create a longer password.

• Use UPPERCASE and lowercase alphabets, numbers, and special characters.

• Use different passwords for different accounts.

### Am I Safe on Cloudways?

Yes!

• Our security system is capable of identifying brute force attacks and banning IP’s being used in such attacks.

• We are always at work to protect our Cloudways Platform and the servers hosted on it.
