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

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

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 done1

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

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

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

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

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.
