GitHub Universe 2021 highlighted several key security initiatives and plans for GitHub's platform, particularly focusing on GitHub Advanced Security (GHAS) and Dependabot. GHAS, designed for GitHub Enterprise customers, offers features such as code scanning, secret scanning, and dependency review. The event addressed user inquiries about the enhancement of security incident reporting, including plans to improve private vulnerability reporting and export functionality for security data. Additionally, GitHub is working on expanding the capabilities of Dependabot and the dependency graph to include more languages and provide more comprehensive security checks. There are efforts to detect malicious packages before advisories are issued and to facilitate easier integration with package managers. GitHub also announced the expansion of CodeQL support to include Ruby and is developing support for Kotlin and Swift, emphasizing its commitment to fostering a secure and collaborative development environment.
