The Critical Nature of Network Security

According to the 2018 Cost of a Data Breach study by Ponemon Institute, the global average cost of a data breach is $3.86 million but, as data breaches continue to soar, the loss, both financial and reputational, has become devastating. Statistics like this speak volumes about the many concerns that organizations face today. It seems that installing even the state of the art cybersecurity solutions and spending millions of dollars on security mechanisms is no longer sufficient; the fact remains that no organization is completely secure. Organizations need security professionals who can help mitigate security threats.

Network security plays a vital role in most of the organizations. It is the process of preventing and detecting unauthorized use of your computer. It protects networks and their services from unauthorized modification, destruction, or disclosure. Network security provides assurance that a network performs its critical functions securely without any harmful side effects.

The important essentials of network security are:

  • Physical security
  • Access controls
  • Authentication
  • Accountability

To establish a secured network, a well-designed network policy has to be established. The network policy characterizes the organization’s idea of an apt computer, usage of the network, and measures to deal with the network incidents.
