How safe are we on the internet? Once we take advantage of the possibilities that the internet provides, as individuals, as businesses and organisations, even as states, we are at the same time exposed to several risks. Cybersecurity aims to manage the relevant risks that are constantly becoming more and more intense. We have heard many times about hackers who "attacked" websites and entire systems of banks and companies, asking for ransom to fix the problem.

The protection "shield" comes from well-trained e-Security personnel, who can detect when an attack has occurred or when it is about to occur and design an effective defense mechanism that covers all possible sources of attack.

What are the most common threats that occur? Should every business be shielded in advance and how is this done? Is protection an evolving and renewed matter? Also, can companies be taught a way of a first defense mechanism? Do we face more or less attacks in Greece in relation to international statistics?

In this Expert Talk, journalist Andreas Panagopoulos discusses the cybersecurity matter with Secretary General of Telecommunications & Posts of the Ministry of Digital Governance, Athanassios Staveris and Professor of Information Security at the Metropolitan College and ISO 27001 Lead Auditor, Dr. Nikos Aroukatos.
