A security analyst on a local network using monitoring
tools is likely to only be able to read contents of traffic
encrypted using IPSec ______ mode.
A. Tunnel
B. Transport
C. Trusted - Answer-Tunnel
Remember, with tunnel mode, encryption does not happen
until just before it leaves the local network. Traffic likely
remains unencrypted between the end user device and
the local network boundary.
_____ is a lightweight cryptography method for signing
messages (MAC). It boasts a relatively undemanding
hardware implementation (only ~3,333 gates required at
1MHz clock rate) making it suitable for IoT implementation.

applied.
A. Salt
B. Ash
C. Ether - Answer-salt

device to the time it arrives at the receiver's device.
A. Tunnel
B. Transport
C. Trusted - Answer-Transport
IPSec ______ mode involves encryption from gateway to
gateway, i.e. just through the public network space.
