What is the role of a VPN in firewall configuration?

A VPN (Virtual Private Network) is primarily designed to provide secure remote access to a network, allowing users to connect securely to their organization's internal network from outside the office. This functionality is essential in firewall configuration, as it establishes an encrypted tunnel over the internet, protecting sensitive data from unauthorized access and eavesdropping.

The correct focus on the role of VPNs includes facilitating remote connections for users who need to access resources within the network securely. This is particularly important for organizations with remote workers or branch offices that require safe connectivity to central resources.

The mention of configuring a new Site-to-Site policy is relevant in some contexts, as Site-to-Site VPNs join two separate networks securely over the internet; however, the underlying role of VPNs in firewall configurations primarily revolves around remote access capabilities. This is crucial for maintaining security and accessibility for distributed users while ensuring that organizational data remains protected.

Understanding the core function of VPNs in the context of firewall setups allows for better implementation and security strategy planning, making it easier to manage risk while supporting organizational productivity and connectivity.
