Software development platform GitHub has made its Advisory Database open to community contributions allowing anyone to contribute insight and intelligence on security vulnerabilities to help improve software supply chain security. The full contents of the database will also now be published to a new, freely accessible public repository under Creative Commons license. Experts say data sharing of this kind is key to improving the security of software supply chains and addressing software-related risks.Security community to benefit from free and open dataMillions of developers and companies use GitHub to build, ship and maintain software. By making its Advisory Database publicly open to community contributions, the firm said security researchers, academics and enthusiasts will be able to provide, share and benefit from additional information and context to further the community\u2019s understanding and awareness of security advisories.\u201cGitHub believes that free and open security data is critical to empowering the industry as a whole to best secure our software supply chains,\u201d the company added. \u201cThe GitHub Advisory Database is the largest database of vulnerabilities in software dependencies in the world. By making it easier to contribute to and consume, we hope it will power even more experiences and will further help improve the security of all software.\u201dGitHub has built a user interface for making contributions, which researchers from the GitHub Security Lab will review. Contributors can suggest changes or provide context on packages, affected versions, and impacted ecosystems, and will get public credit on their GitHub profile once their contribution is accepted. The Open-Source Vulnerabilities (OSV) format will be used for advisories in the repository, GitHub stated.\u201cIn order for vulnerability management in open source to scale, security advisories need to be broadly accessible and easily contributed to by all,\u201d says Oliver Chang, software engineer for Google\u2019s Open Source Security Team. \u201cOSV provides that capability.\u201dData sharing integral to software supply chain securityGitHub\u2019s move is a step forward in securing open-source projects and libraries, Yaniv Balmas, vice president of research at Salt Security, tells CSO. \u201cThe number of publicly reported software vulnerabilities is at an all-time high and keeps growing from year to year. Good and consistent information sharing might be one of the most effective ways to address this issue,\u201d he says.Since GitHub holds the largest portion of open-source code, making the Advisory Database open to community contributions will give software vendors more visibility into the status of security issues in each version of software or shared library they are using, as well as help vulnerability hunters report and fix bugs, Balmas adds. \u201cIt will also help tackle the issue of software supply chain attacks, as it will give vendors a clearer view of each shared software component they use and the status of their security issues.\u201dESET global cybersecurity advisor, Jake Moore, agrees. \u201cThe software supply chain has taken a huge hit over the last few years with vulnerabilities being highlighted and shared in dark marketplaces before their victims have even had a chance to respond,\u201d he says, adding that sharing newfound threat intelligence within trusted communities will enable those who may not be best protected to access the latest in updates and patch information.
