Axel Legay -- La cyber sécurité passe aussi par la sécurité. Ici, celle des chargeurs.

Image
On me demande souvent si cela n'est pas sans risque de laisser son chargeur branché quand on n'utilise pas l'appareil. Analyse ci dessous! Il est fréquent de laisser un chargeur branché en permanence dans une prise, souvent par commodité. Pourtant, il est recommandé d’adopter le réflexe de le débrancher lorsqu’il n’est pas utilisé. 🔥 Un geste de sécurité avant tout Laisser un chargeur branché sans appareil connecté n’apporte aucun avantage fonctionnel . Bien que la consommation d’électricité soit minime , ce comportement peut présenter des risques liés à la surchauffe . Certains chargeurs, notamment de qualité inférieure, peuvent chauffer de manière excessive s’ils restent branchés en continu, ce qui augmente le risque d’incident électrique ou d’incendie . ⚡ Un impact énergétique négligeable D’un point de vue énergétique, la consommation d’un chargeur inactif est très faible . Recharger un téléphone pendant une année complète représente moins de 2 euros sur la facture...

Axel Legay -- Why the Press Is a Frequent Target of Cyber Attacks?

Image
  In a world where information flows faster than ever, journalism has never been more vital — or more vulnerable. The press plays a central role in holding power to account, exposing injustice, and informing democratic debate. But this mission comes at a cost. Media organizations increasingly find themselves under digital siege, facing relentless cyber attacks designed not only to silence but also to manipulate. Behind these assaults lie complex forces: authoritarian governments seeking control, shadowy cyber units, and the chaotic amplification of social media platforms. The State’s Expanding Grip on Information One of the most significant drivers of cyber attacks on the press is the ambition of states — particularly authoritarian regimes — to dominate the narrative. In many parts of the world, governments no longer rely solely on censorship or physical intimidation. Instead, they turn to digital warfare: surveillance, hacking, blackmail, and disruption campaigns engineered to neu...

Axel Legay -- Pourquoi la cybersécurité ne doit pas être laissée aux seules universités

  Introduction La cybersécurité est devenue un pilier fondamental de la stabilité numérique mondiale. Alors que les universités jouent un rôle clé dans la formation des talents, il serait illusoire et risqué de leur confier l’entière responsabilité de la cybersécurité. Cette mission doit être collective, agile et ancrée dans le réel , car les cybermenaces n’attendent pas la fin d’un semestre pour frapper. 1. Le rôle (limité) des universités dans la cybersécurité Les universités forment les bases théoriques : cryptographie, protocoles, gouvernance IT, etc. Mais plusieurs limites émergent : 🐢 Temps long académique : un programme de master met souvent 2 à 4 ans à s’actualiser. 🔧 Peu de pratique offensive/défensive réelle (peu de labs type "Red Team" vs "Blue Team"). 📚 Absence de confrontation au monde réel : peu de contact avec des cyberattaques réelles ou APT (Advanced Persistent Threats). Exemple : en 2023, de nombreuses universités en Europe ...
