Supply Chain Security: Third-Party Risk Assessment Framework
Introduction
Supply chain security has emerged as a critical cybersecurity concern as organizations increasingly rely on third-party vendors, open-source components, and complex supplier ecosystems that introduce significant security risks.
Supply Chain Threat Landscape
Attack Vectors
- Software Supply Chain: Compromised development tools and repositories
- Hardware Supply Chain: Malicious components and firmware
- Service Provider Attacks: Managed service provider compromises
- Open Source Exploitation: Vulnerable or malicious dependencies
Threat Actors
- Nation-state actors targeting critical infrastructure
- Cybercriminal organizations seeking financial gain
- Insider threats within supplier organizations
- Hacktivist groups pursuing ideological goals
Software Supply Chain Vulnerabilities
Development Environment Compromises
- Build system infiltration
- Source code repository manipulation
- Development tool compromise
- Continuous integration pipeline attacks
Dependency Management Issues
- Vulnerable third-party libraries
- Malicious package injection
