Which technology is best suited to securing end-to-end communications for remote workers by establishing a secure tunnel across the network?

• A. TLS
• B. VPNs
• C. DNSSEC
• D. Firewall ACLs

Answer: (B)

Creating a secure tunnel for remote workers is what a VPN does. It establishes an encrypted path between the worker’s device and the organization’s network, so all traffic meant for the corporate resources travels through that secure channel. This gives confidentiality and integrity over public networks and makes the remote device appear as part of the internal network to access resources safely, regardless of the app being used.

TLS protects individual connections between a client and a server, but it doesn’t automatically provide a single tunnel for all of a user’s traffic across the network. DNSSEC secures DNS data to prevent spoofing, not tunneling or general traffic encryption. Firewall ACLs control what traffic is allowed or blocked at network boundaries, but they don’t create encrypted tunnels for remote access.
