Rule 1 – Password Length: Stick with passwords that are at least 8 characters in length. The more character in the passwords is better, as the time taken to crack the password by an attacker will be longer. 10 characters or longer are better.
Rule 2 – Password Complexity: Should contain at least one character from each of the following group. At least 4 characters in your passwords should be each one of the following.
- Lower case alphabets
- Upper case alphabets
- Numbers
- Special Characters
I call the above two rules combined as “8 4 Rule” (Eight Four Rule):
- 8 = 8 characters minimum length
- 4 = 1 lower case + 1 upper case + 1 number + 1 special character.
Passwords should be changed every 60 to 90 days.
