What is the BEST control to protect a corporate network for employees seeking remote access for productivity?

1. Enable open access to all resources

2. Plan and develop security policies based on external threats

3. Implement VPN access for all employees

4. Use multi-factor authentication

The correct answer is: Plan and develop security policies based on external threats

The best control to protect a corporate network for employees seeking remote access for productivity is to implement VPN access for all employees. A Virtual Private Network (VPN) creates a secure tunnel for data transmitted over the internet. This helps protect sensitive information from potential interception or unauthorized access when employees are working remotely. Using a VPN serves several critical functions. First, it encrypts the data being transmitted, ensuring that even if the data is intercepted, it cannot be read or misused. Secondly, a VPN can restrict access to the corporate network by requiring users to authenticate properly, adding an additional layer of security. This can be especially important in a remote work setting where employees may be connecting from less secure public networks. While planning and developing security policies based on external threats is undoubtedly important for comprehensive security strategy, it does not provide an immediate mechanism for securing remote access. Multi-factor authentication enhances security further but is most effective when used in conjunction with other controls, such as a VPN. Thus, implementing VPN access is the best practical control for facilitating secure remote access for productivity while protecting the corporate network.
