You will learn about the different checks provided by OpenSSF Scorecard, how to configure the checks for your environment, and how to automate their implementation.

In April 2014, the Linux Foundation Executive Director Jim Zemlin seized the opportunity to get visibility and managed to get Amazon Web Services, Cisco, Dell, Facebook, Fujitsu, Google, IBM, Intel, Microsoft, NetApp, Qualcomm, Rackspace, and VMware to all pledge to commit at least $100,000 a year for at least three years to the Core Infrastructure Initiative. The initiative continued for many years and eventually transformed into the Open Source Security Foundation. Also due to Heartbleed, the European Commission launched the EU-Free and Open Source Software Auditing project and spent at least a million euros on auditing OpenSSL, the Apache Server, KeePass, and other security-critical open source software.

The idea of using `-fsanitize-minimal-runtime` is interesting. I don't have any direct experience with that option. I've created an issue to investigate maybe adding that to the guide. Thanks for the tip!

These are technical details that are out of the scope of this article, but we think that it is important to mention them because the security strategy of a company should be based on a solid foundation, and these frameworks show that there are already some good starting points, companies don't have to start from scratch. If you want to know more about them or other ways to improve the security of your software supply chain, visit the OpenSSF website.

Participating in the cybersecurity community can be a useful way to gain information about security trends and possible risks. Organizations such as the OWASP, OpenSSF, SANS Institute, and ISC2 promote the exchange of information between organizations and can raise the alarm about emerging issues or hacking strategies.

Today corporations, open source projects, nonprofit foundations, and even governments are all trying to figure out how to improve the global software supply chain security. While these efforts are more than welcome, for the moment, there is hardly any straightforward way for organizations to improve on that front.

> because the ifunc code was breaking with all sorts of build options and obviously caused many problems with various sanitizers

Have you tried Googles grpc fuzzer?

> We support the libFuzzer, AFL++, and Honggfuzz fuzzing engines in combination with Sanitizers, as well as ClusterFuzz, a distributed fuzzer execution environment and reporting tool.

> Currently, OSS-Fuzz supports C/C++, Rust, Go, Python, Java/JVM, and JavaScript code. Other languages supported by LLVM may work too. OSS-Fuzz supports fuzzing x86_64 and i386 builds.

I love fuzzing as a technique and use it quite regularly, but running AFL++ on even a single program occupies all threads of a high end AMD server for weeks. I'm running it locally so only paying for the electricity. If it was a cloud instance it would cost a small fortune. I think this is a reason it is not used more widely.

I will note that Google have a programme for doing fuzz testing on open source projects using computer from their cloud: https://google.github.io/oss-fuzz/

Yes, mosh has fuzz tests in oss-fuzz [1].

We will explore how Jazzer is used to automatically generate malicious inputs for Java programs, and how it compares to Symflower, which can automatically generate unit tests to uncover bugs and errors in your code. With the help of Jazzer, many bugs - some of them even in the OpenJDK - were found already. Also, as of March 2021, Jazzer is officially part of OSS-Fuzz, Google's cloud fuzzing engine. It should be noted that Jazzer is a pure "bug detection" utility that finds reproducers for errors in user code. Symflower can do the same, but provides additional functionalities to boost developer productivity, like generating high coverage unit tests and providing test templates for the software developer or tester.
