Each developer views that tradeoff differently. Security and usability are frequently at odds. You can trust a folder location, a git repository or a git repository owner directly from the trust dialog or the trust settings dialog: Once enabled, Visual Studio will detect if you are attempting to open untrusted content and will show a new dialog that warns you about the security implications:Īfter enabling the feature, all content opened inside Visual Studio 2022 is considered untrusted until you or your organization (via Group Policy) adds it to the list of “trusted locations”. Trusted locationsįor Visual Studio 2022 Preview 3, you’ll have to manually enable the “trusted locations” feature. ![]() Our new functionality consists of two main components: trusted locations & restricted mode. ![]() To that end, we have overhauled our Trust Settings functionality and will provide an additional layer of security when trying to open content (e.g., solutions, projects, files, or folders) that wasn’t previously defined as trusted. With Visual Studio 2022, we want to help you safely browse and edit code no matter the source or author. While this allowed us to create great new experiences, it also brought new security considerations. With the widespread adoption of open-source software, there’s been a shift in how most developers obtain and consume project samples. While at the time it was a good decision, inconsistent usage of the “mark of the web” attribute, led to problems for designs that relied on it. In Visual Studio 2015, we extended the trust coverage to items outside the project scope and leveraged the “mark of the web” attribute, as a trust indicator for those items. When you attempted to open a project from a location that was not previously trusted, the warning dialog would let you know and mention the implications of opening untrusted code. This means that a malicious actor could create a scenario where simply opening content inside Visual Studio could become an attack vector to compromise you or your company.īack in Visual Studio 2002, we introduced a content trust prompt. However, from a threat evaluation perspective, building code is equivalent to execution. This process – based on design-time builds – helps us identify the project structure and its dependencies, and is essential for many of the great features we offer such as code navigation and IntelliSense. To provide the feature rich experience of the Visual Studio IDE, a project system first needs to evaluate the contents you are about to open. While you will benefit from these security improvements out of the box, we’ve made it a priority to provide organizations with the tools to centrally manage the experience to their needs. The new Trust Settings functionality aims to raise awareness about the risks in handling unfamiliar code and helps protect against malicious actors, who are targeting scenarios ranging from opening content (e.g., repositories, solutions, projects and/or files) to building and running applications with Visual Studio. Visual Studio Code recently introduced Workspace Trust, and today we’ll discuss how Visual Studio 2022 is also redesigning it’s trust settings functionality, starting in Visual Studio 2022 Preview 3. Key to this is how the IDE can help developers evaluate the level of trust for code. In Visual Studio 2022 we’ve been focused on developer and team productivity. To reduce the risk of open-source library adoption in the face of such attacks, developers need a toolchain that assists them in evaluating untrusted content. Recent incidents include Nobelium, Octopus Scanner, and ZINC. Software developers are increasingly being targeted by malware.
