SonarLint, a free and open-source IDE extension, now includes advanced rules to protect AWS authentication credentials and Amazon Marketplace Web Service (MWS) credentials from leaking publicly. This feature helps developers identify and prevent leaks of sensitive information before it's committed to a repository, thereby safeguarding their code security. By detecting issues at the point of introduction, SonarLint acts as a first line of defense to catch potential public leaks of credentials, providing clear in-context guidance to address them. The new feature is currently available for various IDEs, including Visual Studio, VS Code, Eclipse, IntelliJ IDEA, and more, allowing developers to secure their code base with just a few clicks.
