With cyberthreats increasing year on year, protecting IT systems and data has become a top priority for businesses.

Our society is increasingly connected, and the rise of technologies such as smartphones, social networks and the Internet of Things is opening up new opportunities for cybercriminals.

What’s more, the malware and other techniques employed by these hackers are also improving. And the criminal forums accessible via the Dark Web enable anyone to exploit them…

According to ANSSI, since 2020, cyber attacks have increased by 400% in France. On a global scale, the cost of cybercrime could double between 2023 and 2027, from $11,000 billion to $24,000 billion.

Faced with this new kind of danger, companies are recruiting experts from within their ranks to defend them. These specialists include IT security administrators.

These exam-based credentials testify to the expertise of their holders, and help them stand out in the eyes of potential employers. The best training courses include certification.

Practical experience is also of great value in reinforcing theoretical knowledge. For example, doing an internship or taking part in real-life projects gives you an insight into the real challenges faced by cybersecurity professionals.

Once you’ve launched your career, it’s essential to continue training and keep abreast of the latest developments in this sector. This means attending conferences and upskilling courses.

The future of the IT security administrator

This profession demands a taste for challenge. Cyber-attacks are becoming increasingly sophisticated, and it’s getting harder and harder to fend them off. However, defense tools are improving, and artificial intelligence is providing invaluable support.

On the other hand, AI also brings new vulnerabilities and represents a new attack vector. Hackers, too, are using it to craft far more powerful malware or phishing attacks that are very difficult to detect.

In Europe, the protection of personal data is a particularly important issue, since companies are required to comply with the General Data Protection Regulation (GDPR) that has been in force since 2018. This imposes reinforced security measures.

Despite warnings deployed worldwide, many corporate employees continue to make mistakes that can compromise system security. The administrator’s duty to raise awareness is therefore a major priority.

The profession is evolving, and its role is no longer confined solely to protecting systems, but also to the organization’s overall security strategy. This requires coordination with all departments.

Data analysis is also playing an increasingly important role in the field of IT security, as it enables anomalies to be detected quickly, enabling instant reaction.
