Cybersecurity refers to the measures taken to keep electronic information private and safe from damage or theft. It is also used to make sure electronic devices and data are not misused. Cybersecurity applies to both software and hardware, as well as information on the internet, and can be used to protect everything from personal information to complex government systems.
Organization and user’s assets include connected computing devices, personnel, infrastructure, applications, services, telecommunications systems, and the totality of transmitted and or stored information in the cyber environment. Cybersecurity strives to ensure the attainment and maintenance of the security properties of the organization and user’s assets against relevant security risks in the cyber environment. The general security objectives comprise the following:
Importance of cyber security
Cybersecurity is important because the 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 in the course of doing business, and cybersecurity describes the discipline dedicated to protecting that information and the systems used to process or store it.
As the volume and sophistication of cyber attacks grow, companies and organizations, especially those that are tasked with safeguarding information relating to national security, health, or financial records, need to take steps to protect their sensitive business and personnel information.
As early as March 2013, the nation’s top intelligence officials cautioned that cyber-attacks and digital spying are the top threat to national security, eclipsing even terrorism.
