Industry-Wide Initiative to Support Open Source Security Gains New Commitments

By Press Release

Open Source Security Foundation adds new members, Citi, Comcast, DevSamurai, HPE, Mirantis and Snyk.

SAN FRANCISCO, Calif., March 9, 2021 OpenSSF, a cross-industry collaboration to secure the open source ecosystem, today announced new membership commitments to advance open source security education and best practices. New members include Citi, Comcast, DevSamurai, Hewlett Packard Enterprise (HPE), Mirantis, and Snyk.

Open source software (OSS) has become pervasive in data centers, consumer devices and services, representing its value among technologists and businesses alike. Because of its development process, open source has a chain of contributors and dependencies before it ultimately reaches its end users. It is important that those responsible for their user or organization’s security are able to understand and verify the security of this dependency supply chain.

“Open source software is embedded in the world’s technology infrastructure and warrants our dedication to ensuring its security,” said Kay Williams, Governing Board Chair, OpenSSF, and Supply Chain Security Lead, Azure Office of the CTO, Microsoft. “We welcome the latest OpenSSF new members and applaud their commitment to advancing supply chain security for open source software and its technology and business ecosystem.”

The OpenSSF is a cross-industry collaboration that brings together technology leaders to improve the security of OSS. Its vision is to create a future where participants in the open source ecosystem use and share high quality software, with security handled proactively, by default, and as a matter of course. Its working groups include Securing Critical Projects, Security Tooling, Identifying Security Threats, Vulnerability Disclosures, Digital Identity Attestation, and Best Practices.  

OpenSSF has more than 35 members and associate members contributing to working groups, technical initiatives and governing board and helping to advance open source security best practices. For more information on founding and new members, please visit: https://openssf.org/about/members/

Membership is not required to participate in the OpenSSF. For more information and to learn how to get involved, including information about participating in working groups and advisory forums, please visit https://openssf.org/getinvolved

New Member Comments

Citi
“Working with the open source community is a key component in our security strategy, and we look forward to supporting the OpenSSF in its commitment to collaboration,” said Jonathan Meadows, Citi’s Managing Director for Cloud Security Engineering.

Comcast
“Open source software is a valuable resource in our ongoing work to create and continuously evolve great products and experiences for our customers, and we know how important it is to build security at every stage of development. We’re honored to be part of this effort and look forward to collaborating,” said Nithya Ruff, head of Comcast Open Source Program Office. 

DevSamurai
“We are living in an interesting era, in which new IT technologies are changing all aspects of our lives everyday. Benefits come with risks, that can’t be truer with open source software. Being a part of OpenSSF we expect to learn from and contribute to the community, together we strengthen security and eliminate risks throughout the software supply chain,” said Tam Nguyen, head of DevSecOps at DevSamurai.

Hewlett Packard Enterprise
“Open source software (OSS) has grown in popularity and will power the modern enterprise infrastructure,” said Sunil James, Senior Director at Hewlett Packard Enterprise. “Its modular nature makes it difficult for customers to easily stitch together trust amongst disparate software and hardware components. Greater industry collaboration is critical to improving the security of OSS. Joining OpenSSF allows us to meaningfully collaborate with others on tooling and best practices to make OSS secure and trusted by default.”

Mirantis
“As open source practitioners from our very founding, Mirantis has demonstrated its commitment to the values of transparency and collaboration in the open source community,” said Chase Pettet, lead product security architect, Mirantis. “As members of the OpenSSF, we recognize the need for cross-industry security stakeholders to strengthen each other. Our customers will continue to rely on open source for their safety and assurance, and we will continue to support the development of secure open solutions.”

Snyk
“Snyk values the security and open source communities and have been working closely with the Linux Foundation for many years,” said Geva Solomonovich, CTO, Global Alliances, at Snyk. “We’ve been making security more accessible to developers by contributing to the Node.js Security Working Group and previous Core Infrastructure Initiative reports. Snyk also helps researchers and open source maintainers responsibly disclose vulnerabilities and assign CVEs. Snyk is thrilled to become an official OSSF member, and we look forward to working with others equally committed to advancing open source security throughout the full software development lifecycle.”

January 2021 Update: New Technical Vision Informs Working Group Progress 

By Blog

The OpenSSF community has been working fast and furious since its formation last year to improve the security of the open source ecosystem. We all know this is no small mission and so we’re taking a moment to report out on all the work that’s happening and invite you to participate.  We also hope to see you at our next Town Hall Meeting on Monday, February 22, 1:00-2:00p ET.  Click here to register.

Technical Vision 

Perhaps most importantly, we’ve worked across companies and geographies to articulate our technical vision for this effort. Our challenge is a big one and a collective and intentional vision allows us to prioritize the pressing needs. 

We envision a future where participants in the open source ecosystem use and share high quality software, with security handled proactively, by default, and as a matter of course:

  • Developers can easily learn secure development practices and are proactively guided by their tools to apply those practices and automatically informed when action is needed to prevent, remediate, or mitigate security issues.
  • Developers, auditors, and regulators can create and easily distribute security policies that are enforced through tooling and automation, providing continuous assurance of the results.
  • Developers and researchers can identify security issues (including unintentional vulnerabilities and malicious software) and have this information swiftly flow backwards through the supply chain to someone who can rapidly address the issue.
  • Community members can provide information and notifications about product defects, mitigations, quality, and supportability and have this information rapidly flow forward across the ecosystem system to all users, and users can rapidly update their software or implement mitigations as appropriate.

Working Group Progress

Our working groups are where the work gets done, and contributors from across the industry have made important progress in recent months. The Technical Vision will help to direct this work. Here are the latest updates: 

Securing Critical Projects
This workgroup focuses on understanding which open source software projects are the most critical so that security work can be prioritized accordingly. The group is working on a Criticality Score and contributed to the Report on the 2020 FOSS Contributor Survey by Harvard & the Linux Foundation.

Security Tooling
The latest tool to come from this workgroup is the CVE Benchmark for tooling and data sets. It analyzes realworld codebases for more than 200 historical JavaScript/TypeScript vulnerabilities, using a range of static application security testing (SAST) tools. 

Identifying Security Threats
This group is making progress on a Security Metrics dashboard for open source projects. An early version of the security metric dashboard has already been demonstrated to the working group.

Vulnerability Disclosures
This group is developing user personas to focus on gaps in current practices and assessing vulnerability management practices and standards that are in use within the community today.

Best Practices
The group has established Security Scorecards, which auto-generates a “security score” through a number of checks on OSS projects. It’s simple to understand, fully automated, uses objective criteria and has the ability to make a large impact across the OSS ecosystem by driving awareness and inspiring projects to improve their security posture. 

This group is also developing a reference architecture and an educational presentation about the core components and relationships of the working group projects; working with the OWASP Security Knowledge Framework (SKF) to provide information on best practices and labs to try them out in various programming languages and improving the CII Best Practices Badge with internationalization that includes more Chinese translators and initial progress on Swahili. 

Security Representative to the OpenSSF Governing Board 

We also want to share that Ian Coldwater has been elected to the OpenSSF Governing Board as Security Representative. Ian is the director of Software Engineering – DevSecOps at Twilio and specializes in hacking and hardening Kubernetes, containers and cloud-native infrastructure. They are also the co-chair of the Kubernetes SIG Security. 

Oh, and if you haven’t already read it, the Linux Foundation’s Director of Open Source Supply Chain Security, David A. Wheeler has a new post about how to prevent supply chain attacks like SolarWinds – with specific recommendations.

Digital Identity Attestation Roundup

By Blog

Author: Kim Lewandowski, on behalf of the Digital Identity Attestation Working Group

We kicked off the first Digital Identity Attestation Working Group meeting under the OpenSSF in August, 2020. The objective of this working group is to enable open source maintainers, contributors and end-users to understand and make decisions on the provenance or origin of the code they maintain, produce and use.

We spent the first several meetings discussing different threat models as it relates to the digital identities of those involved in software supply chains, and what types of attacks are possible in each link of the chain. After this exercise, we’ve filled up our meetings with community presentations as we all try to learn more about this space and brainstorm potential opportunities to work together on mitigating these types of attacks. 

Below is a summary of the presentations to date:

Linux Kernel

  • Presenter: Konstantin Ryabitsev (Linux Foundation)
  • Summary: This presentation is an overview of how the Linux Kernel handles developer identity verification.
  • Slides
  • Youtube

In-Toto

  • Presenter: Santiago Torres-Arias (Purdue University)
  • Summary: This presentation introduced in-toto as a framework to automate compliance for software supply chain operations, onboarding new actors (e.g., developers) within an organization, and verifying best practices on software development lifecycles. Using in-toto, these processes can be cryptographically checked to ensure each actor performed their duties properly, that no steps were missed and no evidence of these steps was tampered with.
  • Slides
  • Youtube

Self Sovereign Identity

  • Presenter: Arnaud Le Hors (IBM)
  • Summary:  A short introduction to Self Sovereign Identity, a new system of identity management allowing individuals and organizations to have control over their digital identity. This presentation introduces the overall architecture based on a specific scenario, highlights key principles, and points to various related initiatives focusing on developing supporting standards and software.
  • Slides
  • Youtube

The Node.js Release Process

  • Presenter: Myles Borins (GitHub)
  • Summary: Myles reviewed how the Node.js project manages releases in a secure and reliable way. We looked at the tools we use to help release managers maintain multiple release lines, our testing infrastructure, and the processes we have in place to ensure reliable consistent releases.
  • Youtube

Git Signing with SSH

  • Presenter: Damien Miller (Google)
  • Summary: Discussion of the goal of having every line of code in a git repository cryptographically attributable back to an author or importer.
    A proposal to refactor git’s cryptography support to allow more signature schemes than just the current gnupg. Proposal to add support for signing using SSH keys, based on the observation that most git users already have a SSH key that they use to authenticate to a repository.  Discussion of progress already made in OpenSSH to support arbitrary signatures that could be compatible.
    Hope that signing using SSH keys could be made near-seamless and that signing of commits and pushes could become default for most users.  Discussion of repository-host side countersigning, etc needed to retain provenance across rebase/merge operations.
  • Slides
  • Youtube

PKI

  • Presenter: Mike Malone (Smallstep)
  • Summary: An introduction to and overview of public key infrastructure (PKI) standards and technologies. Broadly, PKI deals with key distribution and management (enrollment, renewal, revocation, transparency, etc). This presentation explores the standards and practices in place for the Web PKI (HTTPS), and how they could be applied to help secure the software supply chain.
  • Slides
  • Youtube

Janssen

  • Presenter: Mike Schwartz
  • Summary: Janssen is an open source digital identity and access management platform. Organizations can use this software to self-host an identity provider or to build this capability into a product . The project includes “Janssen Auth Server”, which is an OAuth Authorization Server and an OpenID Connect Provider. Janssen Auth Server is a fork of the core component of Gluu Server 4.2.2, which was certified at the OpenID Foundation.  Other components of the Janssen Project include an implementation of a W3C WebAuthn server (FIDO 2), which enables people to enroll, authenticate and manage these new credentials.  In addition to the source code, the Janssen Project publishes cloud native assets and a distribution which can be installed on a VM or bare metal.

Introducing the OpenSSF CVE Benchmark

By Blog

Author: Bas van Schaik

Today, at Black Hat Europe, the Open Source Security Foundation (OpenSSF) unveiled its latest initiative: the OpenSSF CVE Benchmark. The benchmark consists of vulnerable code and metadata for over 200 historical JavaScript/TypeScript vulnerabilities (CVEs). It includes tooling for analyzing the real-world codebases that were affected by these vulnerabilities, using a range of different static application security testing (SAST) tools. The automatically-generated reports will help security teams evaluate different security tools on the market.

Engineering and security teams typically have one main requirement when they consider security tools: effectiveness at detecting vulnerabilities (i.e. produce few false negatives) while maintaining a low false positive rate. That’s exactly what is measured by the OpenSSF CVE Benchmark.

The OpenSSF CVE Benchmark tooling and data are open source and available on GitHub

A new approach to benchmarking

The benchmark addresses two problems that security teams face today when assessing security tools. First, rather than using synthetic test code, the OpenSSF CVE Benchmark uses real historical CVEs. Using this approach, security tools are tested on real codebases that contain real vulnerabilities. Second, by also analyzing the patched version of every codebase, the tools’ false positive rates can be established more accurately.

For each of the over 200 CVEs in the dataset, the CVE Benchmark determines: 

  1. Is a tool able to detect the vulnerability, or does it produce a false negative?
  2. Does it recognize the patch, or does it produce a false positive on the patched code?

Currently, one of the most common methods of assessing the efficacy of a security tool, is to run it on a codebase containing synthetic vulnerabilities. For each popular programming language, there exists multiple such codebases, which are maintained to various degrees. Most of such “benchmark codebases” or “test suites” are worked on by volunteers, while others are published by large organisations (like NIST’s SAMATE initiative, which maintains the Juliet test suite).

Creating codebases with synthetic vulnerabilities is challenging. In many cases, the test suites don’t resemble real codebases: every odd-looking snippet of code is almost guaranteed to be a valid result. This is far from true for real-world code. Requesting that tool vendors optimize their analysis capabilities for such codebases is counterproductive: a tool that performs well on a synthetic codebase is by no means guaranteed to perform well on real-world code.

In fact, real vulnerabilities are often the result of a complex interplay between an application’s own code and its dependencies. For example, user-controlled data might enter a web application through a web framework. It might then flow through the application’s own functions and data structures, to eventually end up in a templating framework. It is close to impossible for a group of volunteers (or a government agency) to continually keep their benchmark codebase or test suite up to date with large numbers and the latest versions of popular frameworks and libraries.

Evaluating a tool’s false positive rate is also critical: if a tool produces too many false positives, engineers will lose too much time to the triaging process, and eventually cease using the tool altogether. Unfortunately, it is hard to gauge a tool’s false positive rate by running it on synthetic benchmark codebases. These codebases don’t ship with patches for their vulnerabilities, making it impossible to ascertain whether a tool would recognize such a patch, or flag up a false positive instead.

We need your help!

The OpenSSF CVE Benchmark is a community project that was initiated by the OpenSSF’s Security Tooling working group, and we would love your help!

The CVE benchmark currently consists of 218 historical CVEs that affected open source JavaScript and TypeScript codebases. We welcome contributions to expand our dataset, or improve the framework tooling.
The benchmark framework currently provides integrations for three different security tools: ESLint, nodejsscan, and CodeQL. Developing an integration for additional security tools is straightforward; it typically requires < 200 lines of code. We invite everyone to contribute their integrations back to our open source repository!

Security Scorecards for Open Source Projects

By Blog

Author: Kim Lewandowski, Google Product Manager

One of the first things I wanted to do when the OpenSSF launched was help people make better decisions about security when consuming open source projects, and draw more awareness to the health of these critical projects we all depend on. Some might argue that it’s almost too easy to introduce a new dependency into your software systems. I’m definitely guilty of this in my previous life as an engineer. I remember pulling in random Python packages when building my own websites and not putting any thought into security. It should be fine if so many other people are using the same package, right?

With the uptick of open source software attacks, there’s more general awareness now that pulling in open source code you didn’t write into your software supply chains should warrant closer review. At large organizations this can get a bit tricky when trying to scale out automated analysis and trust decisions of any new dependencies, or keeping updated on the hygiene of existing ones. These issues are what inspired the new Scorecards project with the OpenSSF that we are releasing today. 

The goal of Scorecards is to auto-generate a “security score” for open source projects to help users as they decide the trust, risk, and security posture for their use case. This data can also be used to augment any decision making in an automated fashion when new open source dependencies are introduced inside projects or at organizations. For example, organizations may decide that any new dependency with low scores has to go through additional evaluation. These checks could help mitigate malicious dependencies from getting deployed to production systems like we’ve seen recently with malicious NPM packages.

We have defined an initial evaluation criteria that will be used to generate a scorecard for an open source project in a fully automated way. Currently the code only works with software repositories from GitHub, but we will extend it to cover other source code repositories. Some of the evaluation metrics used include a well-defined security policy, code review process and continuous test coverage with fuzzing and static code analysis tools.

Using the scorecard data, we want to build a culture of security through improved visibility. We want to work with the community and improve the security health of the critical projects we all depend on.

It’s early days for this project, though we have made some progress on this problem, we have not solved it and need the community’s help in improving these security evaluation metrics, and adding new ones. There’s a small wishlist of issues already in the repo. Let’s work together on a more secure future for open source software!

Announcing: Secure Software Development EdX course, Sign Up Today!

By Blog

The Open Source Security Foundation (OpenSSF) has developed a trio of free courses on how to develop secure software. These courses are part of the Secure Software Development Fundamentals Professional Certificate program, all available on the edX platform. This material is intended for all software developers so they can learn to develop secure software. It focuses on practical steps that any software developer can easily take, not theory or actions requiring unlimited resources.

Those interested can sign up starting October 29, 2020. The course material is expected to be released on November 5, 2020. For more information click here.

Almost all software is under attack today, and many organizations and developers are unprepared in their defense. The Secure Software Development Fundamentals courses will enable software developers to create and maintain systems that are much harder to successfully attack, reduce the damage when attacks are successful, and speed the response so that any latent vulnerabilities can be rapidly repaired. The best practices covered in this program apply to all software developers, and include information especially useful to those who use or develop open source software.

Today 48% of technical hiring managers stated hiring professionals with security expertise is a high priority (as reported in the 2020 Open Source Jobs Report), so there is not a better time to engage in this course. Similarly, Security Software Developers earn 35% more than Software Developers in a US nationwide average (according to ZipRecruiter Sep 25, 2020 data).

The courses in this program discusses risks and requirements, design principles, and evaluating code (such as packages) for reuse. It then focuses on key implementation issues: input validation (such as why allowlists and not denylists should be used), processing data securely, calling out to other programs, sending output, cryptography, error handling, and incident response. This is followed by a discussion on various kinds of verification issues, including different kinds of security tools. The program concludes with a discussion on deployment and vulnerability reporting.

Chris Aniszczyk (CTO of Cloud Native Computing Foundation (CNCF)) said, “In today’s world where more companies are using more software, becoming software companies themselves and everything is becoming connected, security education is more important than ever. At CNCF, we are excited about this new security professional certificate, and intend to have all of our project leadership pass the courses in the program and recommend you do the same in your communities.”

Software developers can take each of the three courses at no cost. They can enroll at any time, and they will then have limited-time access to the course material on EdX. Developers who wish to prove mastery of the material (or have unlimited access time to the material on EdX) can enroll in the Secure Software Development Fundamentals Professional Certificate program for a fee. The courses included in the program are:

  1. Secure Software Development: Requirements, Design, and Reuse (LFD104x)
  2. Secure Software Development: Implementation (LFD105x)
  3. Secure Software Development: Verification and More Specialized Topics (LFD106x)

Those interested can sign up starting October 29, 2020. The course material is expected to be released on November 5, 2020. For more information click here.
