UWE Bristol research to help uncover and mitigate against hundreds of online public software supply chain vulnerabilities

Many software and cloud platforms rely on the use of containerisation, a modern technique of deploying multiple software services quickly, securely and efficiently on large-scale cloud computing resources such as Microsoft Azure and Amazon Web Services (AWS). Platforms such as DockerHub provide an online repository of over 100,000 ready-to-deploy containers that are used widely in many of today’s modern software platforms. Whilst this offers great convenience for development teams, many of these containers may exhibit vulnerabilities, which if not managed, can introduce vulnerabilities into a company software stack. Recent security issues such as the log4j vulnerability and the Solarwinds Orion attack highlight the growing concern around software supply chain security, the dependencies that are made by development teams on third party software, and the implications of identifying and remediating such vulnerabilities later down the line.

As part of our CSC3 research, Alan Mills, Jonathan White and Phil Legg, have developed a suite of docker security visualisation and remediation tools: OGMA and BORVO. The suite of tools enable developer and security teams to quickly identify vulnerabilities against a variety of container security scanning platforms. Results from existing scanning tools can often differ or conflict, and so our aggregated approach helps provide a unified analysis to address conflicts and provide a visual means for thorough examination the results. Our approach also provides a more intuitive risk assessment that considers the true impact of vulnerabilities, such as how easily the vulnerability could actually be exploited by external or internal actors. Furthermore, the suite also provides developers with informed assessment of how to remediate the security issues whilst preserving the intended software functionality that is dependent on the container.

Our research paper “OGMA: Visualisation for Software Container Security Analysis and Automated Remediation” has been peer-reviewed and accepted for the IEEE Conference on Cyber Security and Resilience where the work will be presented and published at the end of July. We will also be sharing our insights in our related presentation on “Securing the Supply Chain – Practicality v Paranoia” at the upcoming BSides Cheltenham conference this weekend, which is a community-organised event for the regional cyber security industry and enthusiasts, and follows our lightning talk on software supply chain security delivered at CYBERUK 2022 earlier this year. OGMA and BORVO are both released as open-source applications that we have made available to the wider research community, to facilitate the examination and remediation of software vulnerabilities in containerised applications.
