Modern enterprise software is typically composed of some custom code and an increasing amount of third-party components, both closed and open source. These third-party components themselves very often get some of their functionality from other third-party components. The totality of all of the vendors and repositories from which these components (and their dependencies) come make up a large part of the software supply chain.

The escalation of international legislative interest in regulating the software supply chain has led to an increasing likelihood that tools such as software bills of materials (SBOMs) and AppSec solutions will become essential for companies doing business in the public sector or in highly regulated industries. However, the process of building and enforcing effective regulations presents challenges as well.

In the face of increasingly impactful malicious attacks, governments of leading economies have turned their attention to the software supply chain security. Regulations like the EU’s Digital Operational Resilience Act (DORA) for financial institutions and the Cyber Resilience Act (CRA) for software and hardware providers Australia’s 2023-2030 cybersecurity strategy, and the U.S.

One of the most vital things to get right in application security is dependency management, and to achieve this, your suite of AppSec tools must be up to date. This means that your vulnerability scanning, detection, and remediation capabilities must be able to identify and address the newest and most exploited vulnerabilities. Do you know what these vulnerabilities are? Have you got them covered? With the help of some of the world’s leading cybersecurity authorities, you can be.

You don’t need us to tell you that open source software is becoming a very significant percentage of commercial software codebases. Open source components are free, stable, and enable you to focus your resources on the innovative and differentiated aspects of your work. But as the use of open source components increases, compliance with open source licenses has become a complex project of growing importance. So how can you stay on top of compliance and what tools are out there to help?

We’re currently seeing a concerted effort from malicious actors to attack the supply chain through intentionally malicious packages. Our recent research shows a 315 percent rise in the publication of malicious packages to open source registries such as npm and RubyGems between 2021 and the end of Q3, 2022; about 85 percent of those packages stole credentials. This trend requires an urgent shift from detection to prevention.

In my previous blog post, I looked at how software supply chain attacks work and what you can do to assess and analyze your security posture. Now, let’s figure out how to use the resultant information to harden your software supply chain against threats.

We’re using more code, software components, and dependencies than ever before, making security breaches an ever-growing threat. It’s easy for developers and DevOps teams to neglect dependency updates when faced with such high volume, but doing so allows applications to fall behind the latest versions if not properly managed. This typically leaves applications using outdated dependencies, which exposes them to ever-increasing security debt and risk.

When it comes to applications and software, the key word is ‘more.’ Driven by the needs of a digital economy, businesses depend more and more on applications for everything from simplifying business operations to creating innovative new revenue opportunities. Cloud-native application development adds even more fuel to the fire. However, that word works both ways: Those applications are often more complex and use open-source code that contains more vulnerabilities than ever before.

DevSecOps best practices are increasingly being adopted to secure software supply chains. The challenge is finding ways to optimize these processes. Here are seven key considerations to help you adopt a successful and secure DevSecOps methodology.
