Question 415
|
With reference to network security across a packet switching network, which of the following provide the most effective solution?
|
End-to-end encryption
|
|
|
Link encryption
|
|
|
Combination of both link and end-to-end encryption
|
|
|
Either link encryption or end-to-end encryption but not both
|
Question 415 Explanation:
The implementation of encryption in packet-switched networks must ensure that essential addressing information can be accessed by the relevant network devices such as switches, bridges and routers. Encryption is broadly termed link layer encryption or end-to-end encryption depending on whether it is applied and re-applied at each end of each link in a communication path, or whether it is applied over the whole path between end systems.
