01Introduction
Most of the code in a modern application was written by someone else. Open source packages, container base images and build tools all run with your application's privileges. Software supply chain security is about trusting them only as far as you should.
02What is Software supply chain security?
Software supply chain security is the practice of securing every third-party component, tool and process involved in building and delivering software. That includes open source dependencies, container images, build systems, CI/CD pipelines and artifact distribution.
It covers software composition analysis (known vulnerabilities in dependencies, ideally filtered by reachability), container image scanning, malicious package detection, build integrity and provenance (SLSA), and inventory through an SBOM.
03How Software supply chain security works
It works in layers from package to pipeline.
- 1.
Resolve the full graph
Enumerate direct and transitive dependencies across every manifest and lockfile.
- 2.
Assess
Match against vulnerability databases, then check reachability, whether your code calls the vulnerable path.
- 3.
Inspect for malice
Analyze install scripts, obfuscated code and typosquats before they run.
- 4.
Attest
Generate a signed SBOM and provenance on each build.
04Threats and risks
Supply chain attacks exploit trust.
Malicious packages
Typosquats and hijacked maintainer accounts that ship credential stealers in install scripts.
Vulnerable dependencies
Known CVEs in transitive packages you never chose directly.
Compromised builds
Tampered CI pipelines that inject code into signed releases.
Alert overload
Thousands of CVE matches, most unreachable, burying the few that matter. See RBVM.
05How Parameter helps
Parameter Supply Chain keeps the queue short and real.
Reachability, not raw CVE counts
Flags vulnerable packages only when your code can reach the vulnerable path.
Malware caught before CI
Inspects install scripts, obfuscated payloads and typosquats before they run.
An SBOM that matches the build
A signed inventory regenerated on every push.
