Cybersecurity is the foster child of the internet. With the proliferation of networks and networks of networks, information (data) and intelligence (software programs and applications) stored in a given network domain became vulnerable to unauthorized access. To prevent such access and its consequences, cybersecurity and information security became an indispensable discipline. Cybersecurity can be generally defined as a technology stack of processes, protocols, and practices to protect computing systems (servers, application endpoints), data, and networks from unauthorized access, malicious attacks, and other forms of intentional and unintentional damage.

Securing the Industrial Internet can be considered as a superset of cybersecurity, since now we are talking about protecting cyber-physical systems.
