The world is turning to the internet as well as the cyber risk also increasing day by day. So, internet users especially those who are using the internet for a bank transaction, social networking, and other critical web management should be very careful and enable all the available security to protect the valuable data / money / social status from the cyber criminals.
Today we are going to discuss the importance of strong passwords and additional layer security like Multifactor Authentication.
Weak and Strong Passwords
Weak
passwords always a big risk in the cyber world because an attacker can easily
guess the password or can crack using different tools. The strong password has
also, risk but chances are very less to guess or break very easily so we can say
the strong password + additional layer security can be better.
Example
or Lists of Weak Passwords
123456,
password, qwerty, 123456789, 12345678, 12345, 111111, 1234567, sunshine, qwerty,
iloveyou, princess, admin, welcome, 666666, abc123, football, 123123, monkey, 654321,
!@#$%^&*, Nothing, secret, Admin, User, iloveyou, admin
Common Password Cracking Methods
There are many passwords breaking methods currently using by hackers. Let us look at what it is and how it is.
- Password Guess – In this method, the attacker guesses the password and try to find
- Hardware/Software Key Logger – A key logger may be a malicious tool or small hardware to capture the keys. The virtual keyboard help to prevent this type of attack.
- Dictionary Attack – The hacker uses a list of words and tries all the probability to find the right one.
- Brute-Force Attack – This is similar to Dictionary Attack, the attacker additionally uses the non-dictionary words, alpha-numeric combinations, etc.
- Combinator Attack - This attack is adding dictionary words to other dictionary words and try to find the password. Example: Two dictionary words 'very' and 'good'. Combinator Method - verygood
- Rainbow Table Attack – This method uses pre-computed database hashes and find the right match
How to Create Strong Passwords?
As
mentioned, the strong password comparatively safe and even less chance to crack
or guess easily so it is better to create a password policy to enforce the
strong password. Remember the following points when you are going to create a
password.
Password
Length
Password
History
Mixture
Combinations
Let
us look at the best practice and policies
The Passwords should meet complexity requirements
Never

Never
use common passwords and dictionary words.
The
password must be at least 8 characters length.
Use
the combinations of uppercase, lowercase letters, and special symbols.
Never
use of previously used passwords.
Conclusion
The passwords are the key to the valuable thing so always ensure to set a strong password plus additional layer security like 2 step verification or any other available features. Here we discussed the different password breaking techniques importance of a strong password. The next article will explain the importance of the 2 step verification with a few demos.
