Which of the following implementation modes would provide the GREATEST amount of security
for outbound data connecting to the internet?

Transport mode with authentication header (AH) plus encapsulating security payload (ESP)

Secure Sockets Layer (SSL) mode

Tunnel mode with AH plus ESP

Triple-DES encryption mode

Tunnel mode provides protection to the entire IP package. To accomplish this, AH and ESP
services can be nested. The transport mode provides primary protection for the higher layers of the
protocols by extending protection to the data fields (payload) of an IP package. The SSL mode
provides security to the higher communication layers (transport layer). The triple-DES encryption
mode is an algorithm that provides confidentiality
