As Qubes OS users, promoters, and developers, we understand how essential it is to be aware of the latest developments in maintaining the security of your favorite operating system. We're excited to share our plans to integrate the TrenchBoot Project into Qubes OS's new Anti-Evil Maid (AEM) implementation. As you may know, traditional firmware security measures like UEFI Secure Boot and measured boot, even with a Static Root of Trust (SRT), may only sometimes be enough to ensure a completely secure environment for your operating system. Compromised firmware may allow for the injection of malicious software into your system, making it difficult to detect. To overcome these limitations, many silicon vendors have started implementing Dynamic Root of Trust (DRT) technologies to establish a secure environment for operating system launch and integrity measurements. We're excited to take advantage of these advancements through integration with the TrenchBoot Project.

Genode - Genode Operating System Framework
We understand the complexity of code and policy as the most fundamental security problem shared by modern general-purpose operating systems. Because of high functional demands and dynamic workloads, however, this complexity cannot be avoided. But it can be organized. Genode is a novel OS architecture that is able to master complexity by applying a strict organizational structure to all software components including device drivers, system services, and applications. The Genode OS framework is an open-source tool kit for building highly secure component-based operating systems. It scales from embedded devices to dynamic general-purpose computing.

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.
