kodintegriteten

Kodintegriteten refers to the assurance that software code remains in its intended, untampered state from development through deployment and operation. It covers both the source code and compiled binaries, ensuring that what is delivered and run is what was authorized by the developers. Preserving code integrity is essential for trust, security, and reliability, especially in environments with frequent updates and many third‑party components.

Key mechanisms to protect kodintegriteten include cryptographic hashes to detect changes, digital signatures and code signing to verify origin and authenticity, and secure pipelines that prevent tampering during build, test, and distribution. Reproducible builds and verifiable artifacts are practices that allow independent verification that binaries correspond to the published source. An up‑to‑date Software Bill of Materials (SBOM) helps identify all components and their provenance, enabling more effective integrity checks and vulnerability management.

Implementation typically spans the secure development lifecycle, including strict access control, versioning, code reviews, secure CI/CD processes, artifact signing, and tamper‑evident storage. Runtime and deployment may employ attestation and trusted execution environments to ensure that code runs in a trusted context and has not been altered after deployment.

Challenges include reliance on external dependencies, complex supply chains, and potential compromises of build or distribution environments. Standards and frameworks related to kodintegriteten include NIST SSDF, ISO/IEC 27034, and SBOM formats such as SPDX and CycloneDX. Effective governance combines technical controls with policies, audits, and continuous monitoring to maintain ongoing code integrity across software lifecycles.
