Un label pour prémunir les communes suisses des piratages informatiques

La cyberattaque ayant visé Rolle (VD) le 30 mai dernier a mis en lumière les failles de sécurité dans les réseaux informatiques communaux. Il existe pourtant un label de cybersécurité en Suisse, que la Confédération cherche à promouvoir.

Des solutions existent pour mieux protéger les données des citoyens et des citoyennes des communes suisses. Depuis deux ans, des experts en cybersécurité testent les vulnérabilités informatiques des communes en les attaquant à la façon des pirates, donnant ensuite accès à un label de cybersécurité.

“On se met à la place d’un acteur malveillant pour voir quelles sont les vulnérabilités, et quel mal pourrait être fait à partir des failles qui ont été découvertes”, explique Nicolas Frey, expert en sécurité au sein du label CyberSafe.

Les failles se détectent en analysant le réseau, mais aussi en testant les failles humaines, via une campagne de phishing. Des e-mails frauduleux, contenant des fichiers ou des liens piégés, sont ainsi envoyés aux employés et aux employées des communes, pour tester leur réaction.

Deepfakes challenge to trust and truth – EPFL Research

Will deepfakes become the most powerful tool of misinformation ever seen? Can we mitigate, or govern, against the coming onslaught of synthetic media?

Our research focuses on the risks that deepfakes create. We highlight risks at three levels: the individual, the organizational and the societal. In each case, knowing how to respond means investigating to better understand the risks of what and to whom. And it’s important to note that these risks don’t necessarily involve malicious intent. Typically, if an individual or an organization faces a deepfake risk, it’s because they’ve been targeted in some way – for example, non-consensual pornography at the individual level, or fraud against an organization. But on the societal level, one of the things our research highlights is that the potential harm from deepfakes is not necessarily intentional: the growing prevalence of synthetic media can stoke concerns about fundamental social values like trust and truth.

Do we live in online bubbles ? EPFL Research

[…] Scientists from EPFL’s Data Science Lab (dlab) in the School of Computer and Communication Sciences, with colleagues from MIT and the Mozilla Foundation have analyzed the browsing and reading habits of tens of thousands of people using a plugin used with the Firefox browser, for the first time gaining a glimpse at polarization from a content consumption perspective. 

Echo chambers are not a new thing but the real replication of these memes happens online. Until now, a lot of polarization research has been around content production because this is what we can easily measure. This population of Firefox users consented to share their data – it’s like some people donate blood for the common good, here people donated their data for the common good,” said Head of the Data Science Lab, Assistant Professor Robert West, and the study’s lead author.

Whilst there have been previous, smaller studies that measured engagement in different ways, uniquely this new study was conducted in vivo, with users going about their normal daily lives, meaning that researchers were able to follow people in their natural habitat. With access to browsing history, unlike earlier studies, this research measured the time that users spent on particular websites, and reading particular articles, rather than whether a user had visited a site or not. 

This additional data provided new evidence of a greater extent of polarization than observed in prior literature, showing that people engaged much more deeply with articles matching their political persuasion, spending more time on news sources matching their partisan beliefs than other information sources. […]
