What is Software Supply Chain Security?
Software supply chain security refers to the practices and technologies used to protect the integrity, authenticity, and security of software components, dependencies, and infrastructure throughout the development lifecycle.
Dependency management and vulnerability scanning
Code signing and verification
Secure build and deployment processes
Continuous monitoring and threat detection
Why It Matters
Modern applications rely on hundreds or thousands of third-party packages. A single compromised dependency can affect millions of applications and their users.
Average web application uses 1,000+ dependencies
90% of code in modern applications comes from third-party libraries
Single vulnerability can cascade across entire ecosystem
The Threat Landscape
Attackers increasingly target the software supply chain because it provides high-impact, low-effort attack vectors.
Typosquatting and dependency confusion attacks
Compromised maintainer accounts
Malicious package uploads
CI/CD pipeline infiltration
