During an internal audit of a financial institution, the auditor identifies that the current password policy requires users to create passwords that are easy to remember and encourages the inclusion of memorable dates and phrases. The auditor is likely to recommend an amendment to this policy. Which of the following changes to the password policy would most effectively increase the security of user accounts?
Password must include elements based on user hobbies or interests to improve memorability, thus enhancing security by reducing the use of written-down passwords.
Password must be a minimum of 14 characters and include a combination of uppercase and lowercase letters, digits, and symbols.
Password must be based on a pattern of keys on the keyboard, such as sequential letter and number combinations, to simplify the creation process.
Password should be updated frequently, suggesting a rotation every month to prevent long-term use.
Requiring a password to be lengthy and to include a complex mixture of character types without directly referencing personal data or easily remembered patterns significantly increases the effort required for an attacker to ascertain or guess the password. This makes it far more challenging for unauthorized parties to gain access, especially when they cannot rely on information like dates or common phrases. The incorrect answers suggest practices that can either be easily exploited by attackers or decrease overall password strength due to predictability.
