This guide details implementing robust code signing for various build artifacts, including binaries, packages, and containers. It covers both traditional GPG key-based signing and modern, keyless signing using Sigstore/cosign. Use this process to establish verifiable trust chains, ensure artifact integrity against supply-chain tampering, prove authenticity, and meet advanced security standards like SLSA.

Cosign is a powerful Sigstore tool designed to secure container images and OCI artifacts. It allows users to sign and verify image provenance using both traditional key-based methods and modern, keyless OIDC workflows. This skill covers generating signatures, attaching critical metadata like SBOM and SLSA attestations, and implementing admission controls for robust supply chain security.

A comprehensive guide for securing container registries by enforcing vulnerability scanning (Trivy, Grype), generating Software Bill of Materials (SBOM), and implementing digital signing using Cosign and Sigstore. This solution is essential for establishing robust CI/CD pipelines and preventing supply chain attacks before image promotion.

This comprehensive guide covers the process of creating, analyzing, and securing Software Bills of Materials (SBOMs). It utilizes Syft to generate standards-compliant SBOMs (CycloneDX or SPDX) from container images and filesystems. The workflow details correlating these SBOMs with known CVEs using Grype for vulnerability analysis, and subsequently signing the artifacts with Cosign. This process is crucial for establishing supply chain trust, ensuring dependency visibility, and integrating vulnerability gating into CI/CD pipelines.

This skill provides methods to verify artifact signatures and SLSA provenance using tools like cosign and slsa-verifier. It is crucial for building secure CI/CD pipelines, detecting supply-chain attacks (e.g., tampering, compromised builds), and ensuring that deployed artifacts originate from trusted sources and build environments. Key features include enforcing keyless OIDC identity pinning and validating SLSA Build Levels.

This skill enables detection, response, and prevention of software supply chain attacks targeting package registries, container images, and CI/CD pipelines. It includes lockfile auditing, provenance verification using tools like Cosign and SLSA, and emergency response playbooks for compromised dependencies.
