Evidence Library ================ Purpose ------- The Evidence Library documents how Thinkwerke designs, produces, and maintains **audit-ready, exportable security and compliance evidence** directly from technical systems and workflows. The goal is simple: - Reduce manual compliance work - Eliminate last-minute audit panic - Reuse evidence across audits, customers, and tenders --- What We Mean by "Evidence" -------------------------- Evidence is not a document written for an auditor. Evidence is **proof** that a control exists, is operating, and is owned. Valid evidence typically includes: - System-generated records - Pipeline outputs - Configuration states - Workflow histories - Logged approvals and exceptions --- Evidence-by-Design Principle ---------------------------- Thinkwerke applies an **Evidence-by-Design** approach: - Controls are implemented with evidence outputs in mind - Evidence is produced automatically - Evidence is verifiable and time-bound - Evidence maps directly to requirements This removes the need for retroactive documentation. --- Evidence Categories ------------------- The Evidence Library is organised into the following categories: - Tender & assurance packs - Security questionnaires - Control-to-proof mappings - Exportable artefacts Each category is designed for a specific stakeholder audience. --- Evidence Lifecycle ------------------ Evidence follows a clear lifecycle: 1. Control definition 2. Technical implementation 3. Continuous operation 4. Evidence generation 5. Export and reuse 6. Review and retention This lifecycle ensures consistency across time and audits. --- Who Uses the Evidence Library ----------------------------- The Evidence Library supports: - Internal security and engineering teams - Auditors and certification bodies - Regulators and supervisory authorities - Customers and procurement teams - Executive and board-level stakeholders Each audience consumes the same evidence, presented differently. --- Relationship to Compliance Mapping ---------------------------------- Evidence artefacts are mapped directly to: - ISO/IEC 27001 controls - NIS2 obligations - CRA requirements - GDPR principles - Customer-specific requirements This mapping is documented in the :doc:`../compliance/crosswalks` section. --- Automation and Tooling ---------------------- Evidence is typically generated via: - CI/CD pipelines - Cloud security tooling - Ticketing and workflow systems - Logging and monitoring platforms - Configuration and policy-as-code Manual evidence is avoided wherever possible. --- Design Goals ------------ The Evidence Library is designed to be: - Reusable across multiple audits - Consistent over time - Easy to explain and defend - Aligned with real system behaviour If evidence cannot be explained technically, it is not considered sufficient. --- Key Takeaway ------------ Strong compliance is built on strong evidence. The Evidence Library turns everyday engineering activity into continuous proof of security and compliance.
