Network Security 2
The Case of Huffman Trucking
Network security is more important today than at any time previously; networks move
larger amounts of data (often secure date), hackers can gain access by various means, and even
employees can compromise the overall security of the network. A company can tighten its
overall security by ensuring that all corporate offices and plants possess the same type of
networking protocols, network operating system (NOS), cabling, and network equipment.
Huffman needs to examine the current state of its networks (both offices and plants), identify
security needs, advantages and disadvantages of various security approaches, and recommend
the optimal combination of cabling, NOS, protocols, and network equipment.
