What should Sarita implement to securely connect branch offices to headquarters via the Internet?

To securely connect branch offices to headquarters via the Internet, implementing a Virtual Private Network (VPN) is a robust solution. A VPN creates an encrypted tunnel for data being transmitted over the public Internet, ensuring that sensitive information is safeguarded against interception and eavesdropping. This is essential for maintaining the confidentiality and integrity of data as it travels between different locations.

VPNs also provide flexibility and cost-effectiveness compared to other methods. Unlike dedicated leased lines, which can be expensive and are limited to specific physical connections, a VPN can be set up over existing Internet connections, allowing for secure communication across all branches without the need for extensive infrastructure changes.

Moreover, VPNs easily adapt to various branch office sizes and Internet service providers while offering users remote access to headquarters' resources securely. Additionally, they support multiple protocols and configurations to meet diverse organizational requirements, further enhancing their effectiveness as a network security solution.

While software-defined wide area networks (SD-WAN) are also becoming popular for optimizing and securing branch connectivity, many SD-WAN solutions include VPN capabilities as part of their architecture, enhancing the secure connection aspect but also adding complexity. On the other hand, remote desktop services primarily focus on allowing access to a single machine's resources rather than creating a secure
