Seminar: Protecting your company from cyber-criminal attacks

The stakes in cybersecurity have never been higher than they are right now. As we know, the Covid-19 crisis has strongly contributed to the increase of criminal attacks on the Internet. Securing an information system means ensuring the integrity, confidentiality and access to the data stored on it. This training aims to show how to protect your data, but also to detect potential attacks and deal with them effectively.
