While businesses primarily uses the networks for data and information sharing, now increasingly businesses are using the networks for virtually commuting their employees as well as carrying out business activities which can take the form of transactions through the networks. This therefore creates a demand for network security initiatives that are aimed at protecting and maintaining a continuously changing network system. Other reasons as to why effective network security systems are required pertain to the aforementioned reasons.
“Security breaches can be very expensive in terms of business disruption and the financial losses that may result. Increasing volumes of sensitive information are transferred across the internet or intranets connected to it. Networks that make use of internet links are becoming more popular because they are cheaper than dedicated leased lines. This, however, involves different users sharing internet links to transport their data. Directors of business organizations are increasingly required to provide effective information security.” (‘Network Security: The importance of effective network security strategies’)
