SGX.Fail

Intel's Software Guard Extension (SGX) promises an isolated execution environment, protected from all software running on the machine. In the past few years, however, SGX has come under heavy fire, threatened by numerous side channel attacks. With Intel repeatedly patching SGX to regain security, we set out to explore the effectiveness of SGX's update mechanisms to prevent attacks on real-world deployments.

NSF investing in secure open-source ecosystems

Open-source software is ubiquitous, supporting artificial intelligence, data science, cloud computing, telecommunications and scientific research tools. Despite these benefits, the number of open-source developers is relatively small, and many projects lack sufficient resources, slowing the pace of innovation and making maintenance difficult. In addition, weaknesses in open-source software, such as security flaws, supply chain risks or insider threats, can spread across many connected systems. In extreme cases, these weaknesses could lead to large-scale failures that affect national or global systems.
