SYPNOSIS

We all exist digitally, our bank accounts, the purchases we make online thanks to e-commerce, our profiles on social networks, the chats we send daily, the data collected by companies and the government, knowing this, it is impossible not to think about how to protect our security on the Internet.

This book was written so that non-technical people, professionals and companies, can be introduced to computer security and can navigate through the Web and the Internet safely, explaining how not to become a prey on the Internet with practical exercises.
