What are the key requirements of a strong password policy?

• A. Regular updates and prohibiting password sharing
• B. Minimum length, complexity, and easy memorization
• C. Length, complexity, and allowing password sharing
• D. Unique passwords for every site and regular updates

Answer: (A)

A strong password policy is fundamental to maintaining the security of accounts and sensitive information. The key requirements for such a policy include regular updates and prohibiting password sharing. Regular updates ensure that even if a password is compromised, the window of opportunity for an attacker is limited, as users are required to change their passwords periodically. This practice mitigates the risk associated with password reuse and static passwords that can be easily exploited over time.

Prohibiting password sharing adds an extra layer of security by ensuring that passwords are kept confidential and only known to the user. When passwords are shared, the control and integrity of that password are lost, increasing the risk of unauthorized access. By having a policy that emphasizes these two key aspects, organizations can significantly enhance their defenses against various threat vectors that exploit weak password practices.
