A computer that lags, a failed update, a forgotten password: these everyday situations remind us that computing is not just about lines of code. It affects how you work, communicate, and protect your personal data. Understanding its basic mechanisms, keeping up with recent developments, and adopting a few practical habits can significantly change how you use your devices.
Cyber Resilience Act: the European regulation that changes the rules of the digital game
Have you ever bought a connected device without wondering if it would receive security patches after its sale? This uncertainty will disappear. The Cyber Resilience Act (Regulation (EU) 2024/2847), which came into effect in December 2024, requires manufacturers to ensure the cybersecurity of their digital products throughout their lifecycle.
In practical terms, any connected device or software sold in the European Union must meet specific requirements to obtain CE marking. Starting from September 11, 2026, manufacturers will have to report exploited vulnerabilities and serious incidents to ENISA and their national CSIRT within strict deadlines: 24 hours, 72 hours, or 14 days depending on severity. Full implementation of the regulation is expected by December 11, 2027.
For individuals, this means that the surveillance camera, connected speaker, or smart thermostat purchased in stores must comply with a verifiable security baseline. Manufacturers will no longer be able to market a product and then stop updating it without legal consequences.
Those who regularly follow Labo Linux’s IT news are familiar with these types of regulatory issues, often approached from a practical angle for users of free systems.
Artificial Intelligence in Business: Cybersecurity as the Primary Application Area
Artificial intelligence is no longer a laboratory topic. In 2025, 18% of companies based in France with 10 or more employees reported using at least one AI technology. This figure represents an increase of 8 points compared to 2024, meaning that usage has tripled in two years.
The primary use case is neither automatic writing nor marketing analysis. It is cybersecurity. AI tools are used to detect suspicious behaviors on a network, sort alerts in real-time, and identify phishing attempts before they reach employees’ inboxes.
Why Security Comes First
A traditional detection system works with known signatures: it identifies a virus that has already been cataloged. AI, on the other hand, analyzes behavior patterns. A file copying itself to twenty workstations in three minutes, a remote access at 3 AM from an unusual country—these anomalies trigger an alert before a human even has time to notice them.
This approach does not replace the network administrator. It saves them time by filtering out the noise. Out of thousands of daily alerts, AI isolates those that warrant human intervention.
Practical Tips for Securing Your Computer Daily
Adopting a few simple habits significantly reduces risks, without requiring advanced technical skills. Here are the actions that really matter:
- Enable automatic updates for the operating system and browser. Most attacks exploit vulnerabilities that have already been patched by the vendor but not yet installed by the user.
- Use a password manager to generate and store unique credentials for each service. Reusing the same password across multiple sites is like giving a master key to a potential attacker.
- Check the real sender of an email before clicking on a link. The address displayed in the “From” field can be misleading: hover over the link without clicking to see the destination URL.
- Back up your files on an external drive or an encrypted cloud storage service at least once a month. A hard drive can fail, and ransomware can lock your data.
These four habits cover the vast majority of common hacking scenarios. A unique password and up-to-date software block most attacks.
Cloud Storage and Digital Sovereignty: What is Evolving in Europe
Storing documents “in the cloud” means entrusting your files to remote servers, often managed by American companies. This reality raises a sovereignty issue, as data hosted in the United States is subject to laws like the Cloud Act, which allows U.S. authorities to access information stored by U.S. law providers.
European alternatives are emerging. Several providers offer hosting on servers located in France or Germany, with end-to-end encryption. For individuals, the criterion to check is simple: where are your data physically stored and under what jurisdiction does the host operate.
Choosing an Appropriate Storage Service
Before subscribing to a service, ask yourself two questions. First, does the service encrypt files on the client side (before sending) or on the server side (after receiving)? Client-side encryption prevents even the provider from reading your documents. Next, does the service offer offline synchronization? Without this feature, an internet outage blocks access to your files.
The choice between convenience and control depends on your usage. A freelancer handling sensitive client data has different needs than a student backing up their courses.
Learning IT Online: Resources That Really Work
Free platforms have proliferated, but their quality varies greatly. Structured courses, with practical exercises and measurable progress, remain more effective than isolated tutorials on social media.
- The modules offered by France Num target beginners and cover the basics: office software, computer protection, smartphone handling.
- Video training like OpenClassrooms allows for deeper learning, with certification paths in web development, systems administration, or database management.
- To understand theoretical foundations (algorithms, data, machines, languages), the Société Informatique de France offers four educational videos accompanied by activity sheets usable in class or for self-training.
Progressing in IT relies on regular practice, not on the passive accumulation of videos. Installing an operating system on an old machine, setting up a home network, or automating a repetitive task with a simple script teaches more than ten hours of theoretical lessons.
IT is evolving rapidly, with new European regulations, massive AI adoption, and sovereignty issues regarding data storage. Keeping an eye on these trends while mastering basic security practices remains the most useful combination for navigating this digital environment smoothly.
