Machine Learning for Computer Security Detection Systems: Practical Feedback and Solutions
Orateur : Anaël Beaugnon (ANSSI)
Machine learning based detection models can strengthen detection, but there remain some significant barriers to the widespread deployment of such techniques in operational detection systems. In this presentation, we identify the main challenges to overcome and we provide both methodological guidance and practical solutions to address them. The solutions we present are completely generic to be[…] -

The Internet of Backdoors
Orateur : par Sam L. Thomas (University of Birmingham, UK)
Complex embedded devices are becoming ever prevalent in our everyday lives, yet only a tiny amount of people consider the potential security and privacy implications of attaching such devices to our home, business and government networks. As demonstrated through recent publications from academia and blog posts from numerous industry figures, these devices are plagued by poor design choices[…] -

Subject Access Request and Proof of Ownership
Orateur : Cédric Lauradoux (INRIA Rhône-Alpes)
The GDPR (General Data Protection Regulation) provides rights on our data: access, rectification, objection, etc. However, this regulation is not binding on how we can exercise these rights. Data controllers have therefore deployed various methods to authenticate subject requests. We have analyzed how this authentication process can fail and examined its consequences. Our study shows that a key[…] -

Splitting the Linux Kernel for Fun and Profit
Orateur : Chris Dalton (HP, Bristol, UK)
This talk looks at a pragmatic attempt at strengthening the security properties of Linux by introducing a degree of intra-kernel protection into the Linux kernel (supported by CPU Virtualization silicon features). Consider it, if you like, an attempt at retrofitting a ‘micro-kernel’ interface into traditionally monolithic Linux whilst maintaining a single linux code base (yes it’s still Linux), no[…] -

Cybersecurity of industrial systems. Open problems and some ideas.
Orateur : Stéphane Mocanu (Inria Rhône-Alpes)
Research in cybersecurity of SCADA systems is a relatively recent field developed mainly into the last decade. Despite the manufacturers progress in hardening the security of device SCADA systems are still prone to severe vulnerabilities and specialized countermeasures are still incipient. This talk aims to present the open problems seen from the boundary between computer science and control[…] -

Differentially Private Linear Sketches: Efficient Implementations and Applications
Orateur : Fuheng Zhao (University of California Santa Barbara)
Linear sketches have been widely adopted to process fast data streams, and they can be used to accurately answer frequency estimation, approximate top K items, and summarize data distributions. When data are sensitive, it is desirable to provide privacy guarantees for linear sketches to preserve private information while delivering useful results with theoretical bounds. To address these[…] -
