A modern person should know a lot and be able in the field of information technology. The development of technologies and the introduction of new means of information processing require a confident computer (laptop, tablet, smartphone, etc.), knowledge of a significant number of software products and rules for working with e-mail, media, the Internet and much more. The work uses a huge amount of information stored on various resources and is of significant value for the company as a whole or for someone personally. At the same time, it does not matter where the computer is used — in the office or on a business trip, on vacation or at home: with the development of network technologies, the level of access to resources increases, as well as the number of various attacks on these resources.
