 How to become an Information security specialist
What is information security?
Information security (IB, English Information Security, short. InfoSec is a set of methods to protect data from unauthorized access or modification both during storage and during transfer from one computer to another.

In practice, the attention of information security specialists is focused on one of the components of data security: confidentiality, integrity and accessibility. So, when storing medical information, we focus on confidentiality. Integrity is most important for financial transactions – no money transfer should be incorrectly credited or debited. To ensure that information is available in press releases, Governments ensure that their websites and systems are kept down to a minimum.

Overview of specialties in the field of information security
The development of technology creates security problems. Cybersecurity Ventures estimates that 3.5 million vacancies will be opened in the information security industry by 2021, and global spending on digital security will exceed $1 trillion. According to the MIT Technology Review, of the candidates applying for the relevant positions, less than a quarter have the necessary qualifications.
