The Secure by Design (SbD) Artefact Library provides a centralised repository of proven solutions to common cyber security problems, supporting the implementation of Secure By Design across UK government.

The Eclipse OpenSmartCLIDE Security Patterns Component

Reference implementations of the QZTMF cryptographic agility engineering patterns: Algorithm Abstraction Layer, Dual-Signature Validation, Key Material Versioning, and Quantum Risk Score.

Security-first ETH settlement implementation. Demonstrates reentrancy-safe native value transfers using low-level calls and strict fallback segregation patterns.

Structured analyses of protocol attack surfaces, incentive failures, and lawful exploit paths using invariant-based methodology.

Production-ready static site architecture on AWS using CloudFront and a private S3 origin, built with Terraform. Focused on security, least privilege, and edge hardening, with enforced TLS versions, security headers, geo restrictions, and an automated GitHub Actions release pipeline for safe deployments.

Reentrancy-hardened vault implementation. Enforces the Checks-Effects-Interactions (CEI) pattern for secure state transitions and utilizes custom errors for gas-efficient validation.

Gas-optimized implementation of immutable ownership patterns. Demonstrates EVM storage bypass techniques using bytecode constants for static identity verification.
