Answer: C
Data recovery, as a corrective action, occurs after a total
network failure (denial of service) and therefore is least
important in assuring security in a networked environment.
The other choices are proactive in nature and directly
impact network security. Server and client authentication
provides a way of verifying that the server bring
communicating with is a valid server, and the server needs
to know that the clients are in fact valid client machines.
Data integrity is required for verifying that the data
received over the network has not been modified during its
transmission, and data confidentiality is required for
protecting information sent over the network from eavesdropping.
