What security solution would you implement to prevent employees from browsing Facebook during work hours?

Implementing a proxy server is an effective solution to prevent employees from accessing specific websites, such as Facebook, during work hours. A proxy server acts as an intermediary between users and the internet, allowing an organization to control web traffic and filter access to certain sites. By configuring the proxy server with rules to block or allow specific URLs, administrators can enforce browsing policies directly and monitor internet usage.

With a proxy server, you can also log user activity, which can help organizations see which websites are being accessed and take further action if necessary. This not only aids in compliance with company policies but also enhances productivity by minimizing distractions from social media sites.

The other options, while essential for different security objectives, do not directly address the issue of restricting access to social media like Facebook. For example, a firewall primarily focuses on controlling network traffic on a broader scale rather than specific web content filtering. An intrusion prevention system is designed to detect and prevent vulnerabilities and attacks, and data loss prevention software focuses on protecting sensitive data rather than managing web access. Therefore, the use of a proxy server is the most appropriate choice for managing employee web browsing during work hours.
