4a. As the heard of the network security department of this noble institution, your mandate is to discuss the measures needed to be taken to curb the nefarious activities of these notorious Hackers. Your submission should touch on seven key areas of network security which will help bring them to a halt. b. Expand extensively on firewalls regarding network security in our data communication. Buttress your input with appropriate diagrams. ci A communication network has a bandwidth of 10 kHz. Calculate the signal-to-noise ratio in dB if the capacity of the channel for a 100Kbps ii. A communications channel with a bandwidth of 4kHz has a signal power to noise ratio of 7. Determine the Channel Capacity. ii. The bandwidth in b above is reduced by 25%. How much should the signal power be increased to maintain the same channel capacity?
