Supply chain security encompasses the measures, processes and technologies used to identify, assess and mitigate risks arising from an organisation's network of suppliers, partners and service providers. It recognises that an organisation's security is only as strong as the weakest link in its supply chain. Threats range from compromised software updates and counterfeit components to data breaches at third-party service providers.
High-profile incidents such as the SolarWinds and Kaseya attacks have demonstrated the devastating impact that supply chain compromises can have. Organisations should implement a structured approach that includes supplier risk assessments, contractual security requirements, continuous monitoring and incident response coordination with key suppliers. Regulatory frameworks including NIS2 and DORA are increasingly mandating supply chain security measures.
