In today’s market, securing the software supply chain and ensuring the safety of customers’ data is imperative for all public and private . In fact, Gartner estimates that by 2025, 45% of organizations worldwide will have experienced attacks on their software supply chains - a threefold increase from 2020. Therefore, it’s paramount for technology vendors and manufacturers to put security, integrity and customer experience at the core of its software development lifecycle practices, especially those vendors who support government, defense, service providers and critical public infrastructure.

The UK government and private sector in particular have seen an increase in software supply chain attacks. Adversaries are becoming ever more brazen in their attempts to infiltrate secure systems. This article explores the challenges presented by these attacks and how the Secure By Design framework helps to combat them. As a software vendor, Quest is committed to securing the software supply chain. Outlined below are seven strategies implemented by Quest to protect customers from potential breaches.

Challenges faced by the UK government and private sector

Both the UK government and private sector face pressing challenges concerning software supply chain attacks. Incidents like the SolarWinds breach have demonstrated the severe implications of these weaknesses, raising concerns about the vulnerability of government systems and private enterprises to malicious infiltration through the software supply chain. Such attacks disrupt operations, compromise trust and violate integrity of software solutions.

UKGOV’s combative measures: Secure By Design and the Cyber Assessment Framework (CAF)

In response to the escalating threats, the UK government's National Cyber Security Centre (NCSC) has taken proactive measures to counter software supply chain attacks, like the 10NCSC-driven Secure By Design principles. These are aimed at the digital and security communities delivering services and they cover the end-to-end delivery life cycle addressing the challenges faced by government organizations. Alongside this, the NCSC advises utilizing the Cyber Assessment Framework (CAF), which provides comprehensive guidance and best practices for securing the software supply chain. By adopting CAF principles, organizations and supply chain software vendors like Quest can strengthen their defences against attacks and contribute to a more secure digital landscape.
