Describe the primary focus of security at the Physical layer and explain where it is most problematic.
What will be an ideal response?
The primary focus of security at the Physical layer is the protection of the medium against unauthorized interception. Eavesdropping typically occurs through unauthorized access to connection devices like hubs, in which the attacker uses special software, called a packet sniffer, to capture and view the packets transmitted across the device. The problem is worst with wireless communications because of the pervasive nature of the transmissions.
