SupplyChainSecurityCon hosted by CNCF + CDF 2021

Open source is everywhere and software is eating the world. However, we now face serious challenges within the security of our software and its supply chain from code commit to production. For this talk, Luke Hinds will outline the current immediate threats and what can be done by us as a community to address the risks we face by harnessing Open Source tooling and open transparent development models.

Code signing is the security foundation of the software supply chains we rely on every day. But if you let yourself think about it for too long -- like we have -- it starts to seem weird that we’re so sure a random download won’t steal our credentials or ransom our data just because someone, somewhere happened to choose a very special point on an elliptic curve.

In this talk, we will explore what a digital signature really means -- and what it doesn’t. We’ll look at the implications of policy choices around key handling, what gets signed, and when we call a signature "valid". And we’ll dive so deeply into the very idea of identity that you may begin to question the nature of your reality.

In this talk, Steven will provide a comprehensive introduction to DevSecOps. He'll help attendees get past the buzzwords and demystify the various kinds of software security scanning that teams can incorporate into their software delivery processes to shift-left security. Equally important - you'll then learn how to apply these principles at scale using the Jenkins Templating Engine to develop tool-agnostic pipelines that can be shared across teams.

The new technologies such as cloud, containers, virtual & cloud native network functions result in tremendous advances in the telecommunications industry.
With the help of these new technologies, the 5G networks that are currently being rolled out all around the world are developed rapidly in heavily disaggregated manner, allowing communications service providers to introduce new services to their users much faster than before.

However, the new technologies and resulting disaggregation is not without their challenges and the security of the software supply chain is one of them.
The components that are part of the 5G networks originate from multiple sources, including but not limited to vendors and open source communities with many integration points and deployed into different environments such as public and private clouds, increasing the risk of breaking the chain of trust.

This session will give a short overview of the next generation telecommunications networks, highlight the challenges, and talk about the opportunities to tackle them in a collaborative manner.

The Python Package Index (PyPI) is one of the oldest software repositories for a language ecosystem and the canonical place to publish Python code. It serves more than 2 billion requests a day, and is almost entirely supported by volunteers and the non-profit Python Software Foundation.

In this talk, we'll review some recent supply-chain attack and how they relate to PyPI specifically. In addition, we'll take a look at some in-progess projects to make PyPI more resilient, secure and sustainable.

SLSA – Supply-chain Levels for Software Artifacts – introduces a comprehensive methodology to prevent tampering with the software supply chain.  To illustrate the impact of SLSA, we follow a few gremlins as they try to introduce malicious code into a container image used by thousands of projects.  At each step of the supply chain we show how SLSA controls raise the cost of attack, preventing the gremlins from causing any harm.

In this talk, we’ll explore the complementary roles that TUF, in-toto, and SigStore play in creating a transparent hack-proof software supply chain that thwarts man-in-the-middle attacks anywhere between developers and end-users. The talk will build off the basics of using in-toto and TUF together to deliver hack-proof updates, especially how it was done for the first time in the industry at Datadog, and then going the extra mile with SigStore. We’ll see how SigStore’s transparent and auditable model holds publishers accountable in this system. Finally, we’ll see a real example of the whole stack in action for the first time with Datadog’s integration, and show just how easy it is to adopt yourself!

With the explosion of interest in SBOMs, it's likely that you've just heard of a few projects for the first time -- even if those projects aren't new, they may be new to you, and you might be asking yourself, "how is X different from Y?" You might also be wondering which projects you should select in order to satisfy the requirements of the Executive Order!
As when starting out on any journey, before entering unfamiliar territory, it is important to understand the lay of the land, pack the right supplies, and get to know your traveling companions.
In this talk, a few maps of the open source supply chain landscape will be shared. Attendees will gain a sense of both the breadth and depth of the challenges ahead, and learn to identify a few essential types of tools for their journey.

If you've analyzed or responded to software vulnerabilities like BadAlloc, KRACK, or the PROTOS SNMP test suite from 2002, then you've encountered the intersection of vulnerabilities and supply chains. Without supply chain knowledge, multi-party coordinated vulnerability disclosure efforts are largely limited to manual investigation, one-offs, and guesswork. Follow-on activities like vulnerability management and risk assessment are also hindered. To what extent are vulnerabilities in upstream dependencies inherited? What happens when build tools have or create vulnerabilities? How might we effectively perform coordinated disclosure and share supply chain knowledge at scale? What part will SBOM (software bill of materials) play?

If you build software on Kubernetes and want to learn more about how to do it in a secure way, then this talk is for you! In this talk, Christie Wilson and Priya Wadhwa will provide a hands on overview to creating a secure zero-trust supply chain on Kubernetes. We'll show you how to use tools like Tekton, Tekton Chains and sigstore together to protect your pipelines and generate provenance for your builds. We'll also cover how the audience can integrate these tools with other projects like In-Toto and SPIRE to securely build, sign and verify software components today.
