Which of the following is essential for a comprehensive data security strategy?

Implementing multi-factor authentication for all accounts is crucial for a comprehensive data security strategy because it significantly enhances the security of user accounts by requiring more than just a password for access. This additional layer of security mitigates the risks associated with compromised passwords, as even if a password is stolen or guessed, the unauthorized user would still need to bypass the second form of verification (such as a fingerprint, security token, or SMS code) to gain access to the account. This makes it considerably more difficult for attackers to gain unauthorized access to sensitive data.

In the context of data security, relying solely on passwords can expose an organization to higher risks, especially considering the prevalence of password-related breaches. By adopting multi-factor authentication, organizations can vastly decrease the likelihood of data breaches and protect sensitive information from unauthorized access. It not only helps in safeguarding accounts but also builds trust in the security measures implemented by the organization.

The other options do not contribute positively to a comprehensive data security strategy. Maximizing cloud storage without restrictions could lead to vulnerabilities if sensitive data is not managed properly. Encouraging the sharing of personal information can expose users to phishing attacks or identity theft. Restricting remote access to data, while it can provide some level of control, may hinder business operations and
