A company needs to establish a secure connection between its headquarters and three branch offices so that users at any site can exchange data as if they were on the same local network. The solution must run over the public internet while providing encryption and a persistent tunnel between the office networks. Which technology best meets these requirements?
Site-to-site VPN
SSL certificates installed on each network node
Point-to-Point Protocol (PPP) links over the internet
A site-to-site VPN creates a permanent, encrypted tunnel between two or more network gateways, allowing entire LANs at different locations to communicate securely over the internet. This lets users at every office access shared resources without re-configuring individual hosts. SSH tunneling is designed for securing traffic to individual hosts or specific ports, not for connecting whole networks. SSL certificates protect browser-to-server sessions, not network-to-network links. Point-to-Point Protocol (PPP) provides a direct link between exactly two nodes and lacks the multi-site, encrypted tunnel capabilities that a VPN gateway offers.
