7-1-4 Password Policies Explained

Key Concepts

• Password Complexity
• Password Length
• Password Expiration
• Account Lockout
• Password History

Password Complexity

Password complexity refers to the requirement for passwords to include a mix of character types, such as uppercase letters, lowercase letters, numbers, and special characters. This complexity makes passwords harder to guess or crack, enhancing security.

Password Length

Password length dictates the minimum number of characters a password must contain. Longer passwords are generally more secure because they increase the number of possible combinations, making them more difficult to brute-force.

Password Expiration

Password expiration policies require users to change their passwords after a certain period. This practice helps prevent the prolonged use of compromised passwords and ensures that passwords are regularly updated, reducing the risk of unauthorized access.

Account Lockout

Account lockout policies automatically lock a user's account after a specified number of failed login attempts. This feature protects against brute-force attacks by temporarily disabling access to the account, giving administrators time to investigate potential security breaches.

Password History

Password history policies prevent users from reusing previously used passwords. By maintaining a record of recent passwords, these policies ensure that users create new, unique passwords, further enhancing security.

Examples and Analogies

Think of password complexity as building a strong fortress. Just as a fortress with multiple layers of defense is harder to breach, a complex password with various character types is harder to crack.

Password length is like adding more locks to a door. The more locks (characters) you have, the longer it takes for someone to break in (guess the password).

Password expiration is akin to changing the locks on your house regularly. Even if someone has a copy of your old key (password), changing it frequently ensures they can't use it for long.

Account lockout is like a security system that activates after multiple incorrect attempts to enter your house. It stops intruders by locking the door and alerting the authorities.

Password history is like keeping a log of all the keys you've ever used. This log ensures you don't reuse old keys, making it harder for someone to gain access with a previously used key.
