An organization needs to secure communication between its main office and several remote branch offices over the internet. Employees at the branches require seamless access to resources at the main office as if they are on the same local network. Which technology should the organization implement to achieve this?
Set up GRE tunnels between offices
Deploy remote access connections for each employee
The organization should implement a site-to-site VPN utilizing IPsec (Internet Protocol Security). A site-to-site VPN connects entire networks at different locations, allowing secure and transparent communication between the main office and branch offices over the internet. IPsec provides the necessary encryption and authentication to protect data in transit. Remote access VPNs are intended for individual users connecting to a network and do not connect entire networks. SSL VPNs are typically client-based and suited for remote user access, not for linking networks. GRE (Generic Routing Encapsulation) tunnels allow for encapsulation of network layer protocols but do not provide encryption on their own, making them insufficient for secure communication without additional security measures.
