Let’s look in detail at the steps involved in being a Cybersecurity Expert.

Performing a diagnosis of the information system

Sometimes assisted by volunteer hackers or intrusion professionals, the cybersecurity expert first studies the information system in its entirety. This diagnosis allows them to propose solutions for maximum security (protection from attacks, but also confidentiality). Through this diagnosis, they then mainly try to identify the weak points of the system.

Setting up various security processes

In close collaboration with IT specialists and the heads of the various departments, the cybersecurity expert defines a security strategy suitable for the company’s needs. This strategy consists of a comprehensive set of procedures, from password management to encryption (encryption and decryption of outgoing and incoming messages), via firewalls, antivirus software, etc.

Ensuring the durability of security systems

To develop solutions and ensure their sustainability, the cybersecurity expert must know the law and specific regulations and be well-informed about new technologies. They must also be able to update security systems according to new threats and the latest technologies.
