Why a Five-Minute Test Can Save Your Supply Chain

The Cybersecurity and Infrastructure Security Agency (CISA) updated its SBOM guidance for 2025, emphasizing that an SBOM should include information about software provenance and dependencies. However, beyond documents, the real defense lies in a quick check: the sniff test of five minutes. This technique allows security teams to detect anomalies in container images and software artifacts before they reach production.

What Does the Sniff Test Consist Of?

The sniff test is a rapid analysis that checks elements such as: unusual file sizes, strange permissions, suspicious layers, or unsigned binaries. Instead of waiting for a full vulnerability scan, this initial check can detect supply chain attacks like malware injection or insecure configurations. For system administrators and DevOps, integrating this step into the CI/CD pipeline is critical.

Impact for SysAdmins/DevOps and the Business

For technical teams, this test reduces false positive noise and accelerates threat detection. For the business, it means fewer disruptions, regulatory compliance, and reputation protection. Implementing an automated sniff test can prevent breaches like those affecting SolarWinds or Log4j. Additionally, it aligns with practices of development as deployment in Kubernetes.

Integration with Existing Tools

You can incorporate the sniff test into your current stack using tools like Docker Bench Security, Trivy, or custom scripts. The key is that it is fast (under 5 minutes) and acts as an initial filter before deeper analysis. Combined with a complete SBOM, this approach provides layered defense.
