Cyber security is the body of technologies, processes, and practices designed to protect networks, devices, programs, and data from attack, damage, or unauthorized access. Cyber security may also be referred to as information technology security.
THE IMPORTANCE OF CYBER SECURITY
It is important because government, military, corporate, financial, and medical organizations collect, process, and store unprecedented amounts of data on computers and other devices. A significant portion of that data can be sensitive information, whether that be intellectual property, financial data, personal information, or other types of data for which unauthorized access or exposure could have negative consequences. Organizations transmit sensitive data across networks and to other devices while doing business, and cyber security describes the discipline dedicated to protecting that information and the systems used to process or store it.
CHALLENGES OF CYBER SECURITY
For effective cyber security, an organization needs to coordinate its efforts throughout its entire information system. Elements of cyber encompass all the following:
The most difficult challenge in cyber security is the ever-evolving nature of security risks themselves. Traditionally, organizations and the government have focused most of their cyber security resources on perimeter security to protect only their most crucial system components and defend against known threats.
