Overview
Supply chain security has become a top priority following high-profile attacks like SolarWinds and Log4j. It involves ensuring that every element that goes into a product or service is trusted and has not been tampered with.
Key Components
- Software Supply Chain: Securing third-party libraries, build pipelines, and distribution channels.
- Hardware Supply Chain: Ensuring the integrity of physical components and preventing the insertion of 'hardware backdoors.'
- Vendor Risk Management: Auditing the security practices of suppliers and partners.
- Software Bill of Materials (SBOM): Maintaining a transparent list of all software components.
Importance
Attackers target the supply chain because a single compromise can provide access to thousands of downstream customers.
