OSS Forensics

Open-source supply-chain incident investigation requires structured evidence collection from local Git, GitHub API, GH Archive, and Wayback Machine snapshots. This process builds a defensible narrative by enforcing strict provenance, guardrails, and a templated final report with an evidence registry and chain of custody.

Forensic evidence collection for OSS security incidents is best handled by coordinating data across multiple sources like local Git, GitHub REST API, GitHub Archive, and Wayback Machine. This multi-source approach ensures comprehensive evidence tracking with content hashes and verification levels.

Chain of custody for open-source forensics reporting works by maintaining an evidence store that tracks content, hashes, and verification levels throughout the investigation. This enforces strict provenance and guardrails, resulting in a templated final report with a complete evidence registry.

IOC enrichment can be used to support supply-chain forensics investigations by augmenting indicators of compromise from external sources. This enriched data is integrated into the multi-source evidence collection process to build a more defensible and comprehensive investigative narrative.

OSS Forensics works with local Git and GitHub Archive for evidence collection by coordinating data from these sources alongside the GitHub REST API and Wayback Machine snapshots. This multi-source approach ensures comprehensive evidence gathering with strict provenance and guardrails.

A templated forensic report for an OSS incident includes a timeline, validated hypotheses, and an evidence registry. It is generated after completing a six-phase workflow that collects, verifies, and reports findings while maintaining a strict chain of custody.
