Advanced Cybersecurity & Threat Landscape
Software Supply Chain Vulnerabilities
Supply chain attacks compromise a trusted component, build tool, or dependency so the malicious code arrives signed and expected. They scale instantly because every downstream consumer installs the update automatically. Defense means knowing what you ship, pinning what you consume, and verifying build integrity end to end.
要点
- Generate an SBOM for every build and store it with the artifact so you can answer 'are we affected' in minutes.
- Pin dependencies to exact versions and hashes; avoid floating ranges in production builds.
- Scan dependencies for known CVEs in CI and block builds that introduce critical findings.
- Protect the build pipeline with MFA, signed commits, and isolated runners that cannot reach production secrets.
- Sign artifacts and verify signatures at deploy time, not just at build time.
- Review third-party packages before adoption: maintainer health, download counts, and recent ownership changes.
- Monitor for dependency confusion and typosquatting in your package registries.
- Keep a rollback plan for every dependency so a bad update can be reverted without a full redeploy.
常见问题
What is dependency confusion?
An attacker publishes a malicious package with a higher version number under an internal package name, tricking the resolver into installing it.
Do we need an SBOM if we use only well-known libraries?
Yes. SBOMs turn incident response from guesswork into a lookup, and customers increasingly require them.
How do we verify build integrity?
Use reproducible builds, signed commits, isolated runners, and artifact signing, then verify the signature before deploy.
Is open source riskier than commercial software?
Both carry risk; open source is more transparent, commercial is more opaque, and the controls are the same: pin, scan, and verify.
