Final answer:
The policy that requires employees to create passwords with at least 15 characters is referred to as a password length policy, which helps enhance security by reducing the risk of brute force attacks.
Step-by-step explanation:
The policy requiring employees to create passwords with at least 15 characters relates to password length. Password length is an aspect of password policy that dictates the minimum number of characters a password must contain. This measure is designed to enhance security by reducing the risk of brute force attacks, which are more difficult to execute against longer passwords. It is crucial to educate users on creating strong passwords that are not only long but also include a mix of letters, numbers, and special characters to further improve security.
Different aspects of password policies may include password expiration, which is about how often users are required to change their passwords, and minimum password age, which determines how long a password must be used before it can be changed. Password complexity requirements usually entail the inclusion of different types of characters such as uppercase and lowercase letters, numbers, and symbols.
