How can social media privacy settings enhance security?

Social media privacy settings are designed to empower users with control over their personal information and the visibility of their posts. When users adjust their privacy settings, they can specifically determine who is allowed to view their content, whether it includes friends, followers, or a broader audience. This selective sharing capability significantly enhances security by helping to prevent unauthorized access to personal data. For instance, by customizing privacy settings, a user can limit potentially harmful interactions and safeguard against identity theft, harassment, or unwanted solicitation.

By contrast, the other choices do not contribute positively to enhancing security. Allowing users to share their information with anyone can lead to vulnerabilities, and making accounts public by default exposes users to a wider audience without their explicit consent, increasing the risk of privacy breaches. Similarly, while limiting account creation could theoretically reduce the number of accounts (and thus potential breaches), it doesn't directly enhance the security of individual users' data on existing accounts.
