A technician is configuring a network for a branch office that will use a router to connect to the main office over the internet. The connection must be encrypted and authenticated to ensure data privacy. Which protocol should the technician configure on the router?
Trap 1: SSL/TLS
SSL/TLS is typically used for securing web traffic, not for router-to-router VPN tunnels, though it can be used in some VPN implementations.
Trap 2: PPTP
PPTP is an older VPN protocol that is less secure and often blocked by firewalls; IPsec is more robust.
Trap 3: L2TP
L2TP alone does not provide encryption; it is often combined with IPsec for security.
- A
IPsec
IPsec encrypts and authenticates IP packets, providing a secure tunnel between routers over the internet.
- B
SSL/TLS
Why wrong: SSL/TLS is typically used for securing web traffic, not for router-to-router VPN tunnels, though it can be used in some VPN implementations.
- C
PPTP
Why wrong: PPTP is an older VPN protocol that is less secure and often blocked by firewalls; IPsec is more robust.
- D
L2TP
Why wrong: L2TP alone does not provide encryption; it is often combined with IPsec for security.
