In the ISO/OSI model, which of the following protocols is
the FIRST to establish security for the user application?
A. Session layer.
B. Transport layer
C. Network layer
D. Presentation layer
Answer / guest
Answer: A
The session layer provides functions that allow two
applications to communicate across the network. The
functions include security, recognition of names, logons and
so on. The session layer is the first layer where security
is established for user applications. The transportation
layer provides transparent transfer of data between end
points. The network layer controls the packet routing and
switching within the network, as well as to any other
network. The presentation layer provides common
communication services, such as encryption, text compression
and reformatting.
