Widespread Insecurities Threaten Global Software Supply Chains

The evolving cybersecurity landscape has brought to light a critical and increasingly prominent issue: the vulnerabilities within software supply chains globally. This concern was underscored by a comprehensive survey conducted by Checkmarx that involved 900 application security professionals across the globe. The survey revealed an alarming statistic: nearly two-thirds of these organizations had experienced compromises in their software supply chains over the past two years, with a remarkable 18% specifically targeted in just the last year alone. Even more disconcerting was the finding that all respondents had been aware of at least one breach at some point, contributing to a growing apprehension about the security of their supply chains. This heightened sense of vulnerability was widespread, with 75% of participants expressing significant concern regarding the integrity and security of their software supply chains.

Rising Anxiety and the Lack of Proactive Measures

Despite the growing anxiety about supply chain security, there appears to be a substantial gap between concern and actionable measures. This misalignment is evident as 57% of respondents identified software supply chain security as a top or significant focus within their organizations, yet only a meager 7% have actually implemented dedicated tools or platforms specifically designed to secure their supply chains. This discrepancy highlights a critical deficiency in the proactive measures that are necessary to adequately address the complex and evolving nature of supply chain threats. Interestingly, there is a positive trend emerging, with approximately half of the organizations now requesting Software Bill of Materials (SBOMs) from their providers. However, the utility of these SBOMs is limited, as less than half of the organizations are equipped to effectively utilize them in securing their supply chains.

Renny Shen, Vice President of Portfolio Marketing for Checkmarx, emphasized the challenges associated with securing software supply chains, citing the complexity and scope of efforts required. He pointed out that effective security measures entail more than just SBOMs and vulnerability/malware detection tools; they also require the adoption of zero-trust security models. In the absence of an all-encompassing solution, DevSecOps teams are often forced to rely on a combination of various tools and strategies to mitigate risks. This fragmented approach underscores the significant challenge of achieving comprehensive supply chain security, necessitating a more coordinated and resource-intensive effort from organizations.

The Open-Source Challenge and Shifting Management Focus

Adding another layer to the challenge of securing software supply chains is the extensive use of open-source code in many deployed applications. The survey revealed that over half of these applications are based on open-source code, which inherently depends on external maintainers for updates and security patches. This reliance on external entities introduces a critical vulnerability, as organizations are at the mercy of third-party maintainers for timely updates and security fixes. The dependency on external maintainers exacerbates the security challenges within the software supply chain, as any delay or oversight significantly increases the risk of exploitation by malicious actors.

Another noteworthy trend from the survey is the escalating level of attention that software supply chain security is receiving within the higher echelons of management. The issue has now become a topic of discussion at the C-level, reflecting its growing importance within organizational priorities. However, despite this increased focus, many organizations still lack defined key performance indicators (KPIs) to ensure the adoption of best practices in DevSecOps. This gap is symptomatic of a broader issue where application security is not prioritized sufficiently, leading developers to focus predominantly on creating new code rather than addressing existing vulnerabilities in the software supply chain.

Mixed Success of Shifting Security Left and Future Directions

Securing software supply chains is increasingly challenging, largely due to the widespread use of open-source code in many applications. A survey indicated that over half of these applications rely on open-source code, requiring updates and security patches from external maintainers. This dependency introduces significant vulnerabilities, as organizations must rely on these third-party maintainers for timely fixes. Any delay or oversight from these external entities heightens the risk of exploitation by malicious actors, thus complicating the security landscape of the software supply chain.

Additionally, the survey highlighted a growing awareness of software supply chain security, which has ascended to the C-suite level within many organizations. This elevation underscores its significance in corporate priorities. Nevertheless, despite this heightened focus, numerous organizations lack clear key performance indicators (KPIs) to adopt best practices in DevSecOps. This shortfall indicates a broader issue: application security is not given enough priority. Consequently, developers often concentrate more on creating new code rather than addressing existing vulnerabilities, further endangering the software supply chain’s integrity.
