Establishing trusted, time-stamped records of system states in distributed environments presents a significant challenge for maintaining accountability and security. Organizations often struggle to produce non-repudiable proof that a specific check was performed or that a system was in a particular state at a precise moment in time. SCANDALE is a libre software solution designed to address this challenge by providing a robust backend architecture for collecting data from distributed probes and storing immutable proofs of those checks. Its core components include a high-performance HTTP API with real-time capabilities, an agent-based backend built on the Smart Python Agent Development Environment (SPADE) for scalable probe management, and a dedicated service for cryptographic timestamping in compliance with RFC 3161. The platform’s primary contribution is its ability to transform operational measurements into cryptographically verifiable evidence, yielding a durable and non-repudiable audit trail.
