Dependencies in Modern IT Systems

The variety of dependencies in modern IT systems provides several advantages, but also has a strong impact on the security and resilience of these systems. A number of recent incidents, such as the “SolarWinds attack” on US governmental agencies, underline the difficulty of securing systems that are composed of various apparently independent components.

How aware are organisations of their IT dependencies? How do they manage them? How are dependencies taken into account in the decision process? The goal of this workshop is to gather experiences, and to present approaches that tackle these dependency issues, from theoretical and practical points of view.

This event is organized by the Swiss Support Center for Cybersecurity (SSCC), in collaboration with the Center for Digital Trust (C4DT) at EPFL and the Zurich Information Security Center (ZISC) at ETHZ.

Zero-trust cloud week – data protection in the cloud

Today, it’s often more cost-effective to host services in the cloud instead of in its own premises. But how protected is our sensitive data in the cloud? We readily encrypt data in storage and protect it while in transit. But what about when data is “in use”? It is a legitimate concern in increasingly cloud-dominated infrastructures. Moreover, how to make sense of the different laws governing the sensitive data?

During this week we will explore how privacy-enhancing computation technologies complement a zero-trust strategy by addressing the vulnerability of data in use in the cloud. We will also discuss the legal framework which is required to balance economical interest of companies with the individual’s data privacy concerns.

12 Questions on the Digital Immunity Passport

The certificate linked to the virus will not be available before June in Switzerland. Until then, here are twelve answers linked to questions of security, data and accessibility concerning what some call the “Immunity Passport”. In particular, Jean-Pierre Hubaux, C4DT Academic Director, provides insights on the questions linked to data.

EPFL/C4DT Panel – Should We Trust Digital Immunity Passports?

There is much debate about the use of digital immunity passports as a response to the COVID-19 pandemic. Such digital tools to certify immunity could help spur economic recovery, but raise ethical and privacy concerns. How to build trust in such a solution? What elements make them interoperable among countries? How is people’s data related to their immunity status governed?

A panel of prominent specialists will discuss these and other questions from 4 different angles – ethical, business, political/governance and scientific – during a two-hour moderated discussion.

ROBIN – Robust Machine Learning

In communication systems, there are many tasks, like modulation recognition, for which Deep Neural Networks (DNNs) have obtained promising performance. However, these models have been shown to be susceptible to adversarial perturbations, namely imperceptible additive noise crafted to induce misclassification. This raises questions about the security but also the general trust in model predictions. In this project, we propose to use adversarial training, which consists of fine-tuning the model with adversarial perturbations, to increase the robustness of automatic modulation recognition (AMC) models. We show that current state-of-the-art models benefit from adversarial training, which mitigates the robustness issues for some families of modulations. We use adversarial perturbations to visualize the features learned, and we found that in robust models the signal symbols are shifted towards the nearest classes in constellation space, like maximum likelihood methods. This confirms that robust models not only are more secure, but also more interpretable, building their decisions on signal statistics that are relevant to modulation recognition.

Secure Distributed-Learning on Threat Intelligence

Cyber security information is often extremely sensitive and confidential, it introduces a tradeoff between the benefits of improved threat-response capabilities and the drawbacks of disclosing national-security-related information to foreign agencies or institutions. This results in the retention of valuable information (a.k.a. as the free-rider problem), which considerably limits the efficacy of data sharing. The purpose of this project is to resolve the cybersecurity information-sharing tradeoff by enabling more accurate insights on larger amounts of more relevant collective threat-intelligence data.
This project will have the benefit of enabling institutions to build better models by securely collaborating with valuable sensitive data that is not normally shared. This will expand the range of available intelligence, thus leading to new and better threat analyses and predictions.

Using “proof of personhood” to tackle social media risks

The ease of creating fake virtual identities plays an important role in shaping the way information—and misinformation—circulates online. Social media platforms are increasingly prominent in shaping public debates, and the tension between online anonymity and accountability is a source of growing societal risks. This article outlines one approach to resolving this tension, with “pseudonym parties” that focus on proof of personhood rather than identity. Pseudonym parties are a low-tech approach to important digital challenges, linking online activity to anonymous digital tokens that are obtained by being physically present at an appointed time and place.

Digital Cooperation Dialogues – Dialogue 5 : Data and Technology for Development

The implementation and monitoring of the Sustainable Development Goals (SDGs) has shown the critical role of data and technology to advance sustainable and inclusive development. The COVID-19 crisis has highlighted the importance of leveraging data and digital technologies to ensure a rapid, agile, and effective response to both the pandemic as it unfolds and the economic recovery in its aftermath. Data plays a catalytic role in informing targeted decision-making at the national and supranational levels while technology can be harnessed to realize new and innovative ways to implement tangible solutions on the ground.

Under the overarching theme of harnessing data and technology for development, this cross-sectorial dialogue will feature two complementary discussions. The first panel will focus on data for development, presenting the World Bank SDG Atlas and its innovative data visualizations, and discussing the role of data in leading a resilient recovery and achieving the SDGs. The second panel will focus on technology for development, presenting EPFL’s Tech4Dev initiative and showcasing best practices in technology transfer that can be adopted by multiple stakeholders in international development.

Why Blockchain is Not Yet Working – 2021

This Monday I presented the following article. It discusses blockchains shortcomings. Even if it has been written in 2018, it is still very up-to-date… What follows here is a very opinionated piece. As such it reflects the journey I did in blockchains over the past 6 years. And I’m sure I missed out a lot (…)

immutable.js, concurrent-safe data structures

Concurrent programming is one the oldest and hardest issues in the Computer Science Book. For years, we have been using locks, big threads sharing the minimum, using optimistic reasoning for “how data will be updated”. And we are still stuck with the same issues of some part of the code “failing” to use the updated (…)

Zoom it out

We’ve been looking at the very nice https://gather.town and played around with it. Instead of having a fixed view of all participants, you can walk around and ‘meet’ different persons in gather.town. You can edit the space your liking. It looks very much like a very old-school Zelda: What I liked a lot about it (…)

Ansible: powerful automation made easy

The management of IT infrastructure is a constantly evolving topic. A very interesting concept that emerged in the last decades is the idea of infrastructure as code: instead of configuring servers in an artisanal fashion, the process is formalized into definition files, which are then automatically “executed”. There are multiple advantages, notably: The files always (…)

COVID Response and Digital Trust

While the SwissCovid proximity tracing app was designed as decentralized and privacy-preserving, adoption rates have been low, and non-users have cited privacy and data protection as the top reason for not adopting. Similar results have been seen in other countries. Given the potential benefits of such an app, and users willingness to use apps with less privacy and arguably less social benefits, this suggests a need for a better understanding of privacy along with a greater focus on generating digital trust in society.

IHEID’s Centre for Trade and Economic Integration and the Global Health Centre invite you to join them for a panel discussion on the privacy features of the proximity tracing apps, the implications of such tech for global health, and general privacy and online trust, with a view to the lessons learned, and what can be done better.

C4DT digital ID week

On the 7th of March the Swiss population will vote on a law the Federal Council and the Parliament have prepared establishing an identification system recognized by the Confederation: the e-ID. Opportunities that arise through digital identification will not only depend on a country’s implementation but also on the trust which its citizens have in its government and institutions. During the week of the 8th to 12th of March, which follows the referendum, we would like to
– discuss the eID law and compare it to the one already implemented by other countries,
– discuss the population’s trust and willingness to adopt a national eID,
– get the perspective of a Swiss Consumer group and learn about the tech implementation and perspective of a digital ID provider,
– hear researchers’ point of view on the implementation challenges, possible solutions and research trends.
Finally, we will try to identify and frame a challenge / use case on which the eID workgroup can solve with the support of research.
Please note that this is a C4DT community event only.

A Journey With Predikon (1/3)

While votes seem to yield increasingly surprising results, such as the election of Donald Trump in 2016 or the Brexit vote in the UK defying pre-vote polls and initial vote counting predictions, Swiss vote results are swiftly being predicted by Predikon. We will follow the evolution of the project until the next vote, which will take place on March 7th. An article every month will enable you to observe the evolution of the project, (almost) live, accompanying Victor Kristof in the improvement of Predikon.
