Best Practice for the Password Policy

A password is a secret string of characters used to verify a  identity and grant access to systems, applications, or data via any account. Without a strong password policy, security gaps open up, making systems vulnerable to attacks, data loss, and compliance violations.

The best practice for the Password Policy which is recommend :-

• Define Minimum Password Length
  • Longer passwords are harder to crack.
  • At least 12–16 characters
  • For higher security environments, consider requiring 16+ characters is recommended
• Password Complexity
  • Password complexity refers to rules that require passwords to contain a mix of different character types, making them harder to guess or crack.
  • A complex password typically includes at least three or all four of the following character types:
    • Uppercase letters
    • Lowercase letters
    • Numbers
    • Special characters
• Prevent Reuse the Password
  • To prevent password reuse as part of a password policy, you can implement the following security measure commonly referred to as a "Password History Policy". This policy ensures users cannot reuse their previous passwords for a defined number of password changes.
  • Disallow reuse of the at lease last 5–10 passwords.
  • Helps avoid repeating weak or previously compromised passwords.
•
