Cyber Security Interview Questions and Answers

Cyber Security Interview Questions and Answers for freshers experienced professionals.

Cyber security (computer security or IT security) is the protection of computer from the theft and damage to their hardware, software data or personal information, as well as from disruption or misdirection of the services they provide. Cyber security refers to the body of technologies, processes, and practices designed to protect networks, devices, programs, and data from attack, damage, or unauthorized access.

Cyber security is most 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 in the course of doing businesses, and cyber security 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.
