The State of Open Source Security Highlights Many Organizations Lacking Strategies to Address Application Vulnerabilities Arising from Code Reuse BOSTON — June 21, 2022 — Snyk, the leader in developer security, and The Linux Foundation, a global nonprofit organization enabling innovation through open source, today announced the results of their first joint research report, The State of Open Source Security. The results detail the significant security risks resulting from the widespread use of open source software within modern application development as well as how many organizations are currently ill-prepared to effectively manage these risks. Specifically, the report found: Over four out of every ten (41%) organizations don’t have high confidence in their open source software security; The average application development project has 49 vulnerabilities and 80 direct dependencies (open source code called by a project); and, The time it takes to fix vulnerabilities in open source projects has steadily increased, more than doubling from 49 days in 2018 to 110 days in 2021. “Software developers today have their own supply chains – instead of assembling car parts, they are assembling code by patching together existing open source components with their unique code. While this leads to increased productivity and innovation, it has also created significant security concerns,” said Matt Jarvis, Director, Developer Relations, Snyk. “This first-of-its-kind report found widespread evidence suggesting industry naivete about the state of open source security today. Together with The Linux Foundation, we plan to leverage these findings to further educate and equip the world’s developers, empowering them to continue building fast, while also staying secure.” “While open source software undoubtedly makes developers more efficient and accelerates innovation, the way modern applications are assembled also makes them more challenging to secure,” said Brian Behlendorf, General Manager, Open Source Security Foundation (OpenSSF). “This research clearly shows the risk is real, and the industry must work even more closely together in order to move away from poor open source or software supply chain security practices.” (You can read the OpenSSF’s blog post about the report here) Snyk and The Linux Foundation will be discussing the report’s full findings as well as recommended actions to improve the security of open source software development during a number of upcoming events: Session at Open Source Summit North America in Austin, TX, titled, “Addressing Cybersecurity Challenges in Open Source Software,” taking place Tuesday, June 21, at 12 p.m. local time (CT). Webinar taking place Tuesday, June 28, at 1 p.m. ET, to register, visit here. Webinar taking place Wednesday, June 29, at 9 a.m. ET, to register, visit here. 41% of Organizations Don’t Have High Confidence in Open Source Software Security Modern application development teams are leveraging code from all sorts of places. They reuse code from other applications they’ve built and search code repositories to find open source components that provide the functionality they need. The use of open source requires a new way of thinking about developer security that many organizations have not yet adopted. Further consider: Less than half (49%) of organizations have a security policy for OSS development or usage (and this number is a mere 27% for medium-to-large companies); and, Three in ten (30%) organizations without an open source security policy openly recognize that no one on their team is currently directly addressing open source security. Average Application Development Project: 49 Vulnerabilities Spanning 80 Direct Dependencies When developers incorporate an open source component in their applications, they immediately become dependent on that component and are at risk if that component contains vulnerabilities. The report shows how real this risk is, with dozens of vulnerabilities discovered across many direct dependencies in each application evaluated. This risk is also compounded by indirect, or transitive, dependencies, which are the dependencies of your dependencies. Many developers do not even know about these dependencies, making them even more challenging to track and secure. That said, to some degree, survey respondents are aware of the security complexities created by open source in the software supply chain today: Over one-quarter of survey respondents noted they are concerned about the security impact of their direct dependencies; Only 18% of respondents said they are confident of the controls they have in place for their transitive dependencies; and, Forty percent of all vulnerabilities were found in transitive dependencies. Time to Fix: More Than Doubled from 49 Days in 2018 to 110 Days in 2021 As application development has increased in complexity, the security challenges faced by development teams have also become increasingly complex. While this makes development more efficient, the use of open source software adds to the remediation burden. The report found that fixing vulnerabilities in open source projects takes almost 20% longer (18.75%) than in proprietary projects. About The Report The State of Open Source Security is a partnership between Snyk and The Linux Foundation, with support from OpenSSF, the Cloud Native Security Foundation, the Continuous Delivery Foundation and the Eclipse Foundation. The report is based on a survey of over 550 respondents in the first quarter of 2022 as well as data from Snyk Open Source, which has scanned more than 1.3B open source projects.

The open specification for defining asynchronous APIs gains momentum, seeks neutral home for open governance, community growth and industry adoption SAN FRANCISCO, Calif., March 30, 2021 – The Linux Foundation, the nonprofit organization enabling mass innovation through open source, today announced it will host the AsyncAPI Initiative. AsyncAPI is a specification and a suite of open source tools that work with asynchronous APIs and event-driven architectures. It is the fastest-growing API specification according to a recent developer survey, tripling in production usage from 2019 to 2020. Founding sponsors of the AsyncAPI Initiative include Ably Realtime, Apideck, Bump, IQVIA Technologies, Slack, Solace, and TIBCO, and AsyncAPI recently announced a partnership with Postman. Today, AsyncAPI is in production at Adidas, PayPal, Salesforce, SAP, and Slack, among other enterprise environments. “As the growth of AsyncAPI skyrocketed, it became clear to us that we needed to find a neutral, trusted home for its ongoing development. The Linux Foundation is without question the leader in bringing together interested communities to advance technology and accelerate adoption in an open way,” said Fran Méndez, who created AsyncAPI in 2016. “This natural next step for the project really represents the maturity and strength of AsyncAPI. We expect the open governance model architected and standardized by the Linux Foundation will ensure the initiative continues to thrive.” AsyncAPI helps unify documentation automation and code generation, as well as managing, testing, and monitoring asynchronous APIs. It provides language for describing the interface of event-driven systems regardless of the underlying technology and supports the full development cycle of event-driven architecture. AsyncAPI is considered a sister project of the OpenAPI Initiative, which is focused on synchronous REST communication and is also hosted by the Linux Foundation. “The Linux Foundation is pleased to provide a forum where individuals and organizations can come together to advance AsyncAPI and nurture collaboration in a neutral forum that can support the kind of growth this community is experiencing,” said Chris Aniszczyk, CTO and Vice President, Developer Relations at the Linux Foundation. For more information, please visit: https://www.asyncapi.org Supporting Quotes Łukasz Górnicki, AsyncAPI “AsyncAPI at Linux Foundation is another brick needed to build a solid and sustainable community for the project. We are securing a perimeter for AsyncAPI and can focus on expanding the vision of making all the specs work together for the user’s good.” Bill Doerrfeld, NordicAPIs “Open standards are only as strong as their community effort. The details of the AsyncAPI charter represent their ongoing community mission and goal to retain vendor neutrality around the format. AsyncAPI is taking an active role in enacting this by limiting company representation per TSC, privileging work over money, and other strategies.” Kin Lane, Postman “AsyncAPI joining the Linux Foundation is the final cornerstone in the foundation of the open source event-driven API specification. This creates solid groundwork for defining the next generation of API infrastructure, beginning with HTTP request and response APIs, but also event-driven approaches spanning multiple protocols and patterns including Kafka, GraphQL, MQTT, AMQP, and much more. And all of that, in turn, will provide what is needed to power documentation, mocking, testing, and other critical stops along a modern enterprise API lifecycle.” Matt McLarty, Salesforce “Seeing how AsyncAPI has blossomed has been incredible. Its progress has been guided by two key principles in my opinion: a focus on solving real world problems, and a focus on community. As the world of synchronous APIs and event-based communication converges, AsyncAPI plays a vital role in levelling the API playing field.” About the Linux Foundation Founded in 2000, the Linux Foundation is supported by more than 1,000 members and is the world’s leading home for collaboration on open source software, open standards, open data, and open hardware.
