Tamper-Evident Audit Trails & Compliance Reporting

SmartERP 19 records every privilege grant, revocation, and SoD breach in an append-only ledger (smarterp.rbac.audit).

Audit Log Ledger Properties#

• Append-Only Architecture: SQL UPDATE and DELETE actions are blocked on smarterp.rbac.audit via database-level triggers.
• Cryptographic Event Hash: Each log entry captures an MD5/SHA256 signature combining (user_id, role_id, timestamp, authorizer_id).
• Periodic Access Certification: Compliance officers run quarterly recertification campaigns where department heads must re-verify active user roles.
