Getting started with Software Supply Chain security and SBOMs

The first step involves identification and prioritization of key software assets, often termed as "Crown Jewels," which are vital for the operational continuity and security of the organization.

Following the compilation of a critical asset inventory, this step guides you on generating an SBOM with the use of freely available tools.

In many cases, vulnerabilities in third-party components can expose your organization to risks. This chapter talks about how to manage 3rd party ICT risk and other external services and products using externally sourced SBOMs.

With a comprehensive inventory of software assets and SBOMs in hand, you are well-positioned to dive into the critical process of vulnerability analysis. In this step we cover the process of translating the transparency gained from SBOMs into actionable insights.

Managing risk early in the software development lifecycle (SDLC), commonly referred to as "shifting left" coupled with the strategic prioritization based on risk, ensures that security is a fundamental component of the development process, rather than an afterthought.

Establishing clear security policies and determining acceptable risk levels are crucial components of a robust cybersecurity risk management strategy. By crafting well-articulated policies, organizations can ensure their security practices are in harmony with their overarching security goals.

In the realm of cybersecurity, vigilance is not a one-time effort but a continuous process. This chapter discusses the strategies for implementing continuous vulnerability management and the methodologies for measuring and enhancing the security posture over time.

Sharing SBOMs with customers and regulatory entities is a crucial step in the cybersecurity maturity journey. It not only enhances transparency and builds trust with customers but also ensures that organizations remain compliant with regulatory requirements.
