How does a Virtual Private Network (VPN) relate to firewalls?

A Virtual Private Network (VPN) is designed to create a secure and encrypted connection over a less secure network, like the internet. This is particularly important when sensitive data is being transmitted, as it protects against eavesdropping and other security threats.

Firewalls, on the other hand, are security devices or software that monitor and control incoming and outgoing network traffic based on predetermined security rules. They help protect networks from unauthorized access and threats.

When a VPN is implemented, it often works in conjunction with firewalls. Firewalls may enforce access controls and filtering for the VPN traffic, ensuring that the data transferred through the VPN adheres to the organization's security policies. Additionally, firewalls can be configured to allow or restrict VPN traffic to enhance network security further.

In this context, the collaboration between VPNs and firewalls enhances the overall security posture of the network, making option B the correct choice. It highlights the cohesive relationship between both technologies in protecting data and managing network security efficiently.
