security-architecture-patterns

Security architecture research repository focused on how modern systems fail at scale and how to design resilient, measurable mitigations.

Start Here

1. Read METHODOLOGY.md for analysis standards.
2. Start with JWT Revocation Failure as the flagship deep-dive.
3. Use PATTERN-INDEX.md to navigate cross-topic patterns.
4. Run companion demonstrations from demo/.

Repository Scope

This repository is an architecture research platform.

It focuses on:

• distributed identity and trust failures
• multi-tenant boundary breakdowns
• control-plane and software supply-chain risk
• agentic and zero-trust implementation failures

Who This Is For

Designed for:

• Security architects
• Staff+ engineers
• Platform security teams
• Cloud-native engineering teams
• Security researchers

Research Principles

• Architecture-first analysis.
• Realistic operational assumptions.
• Distributed-systems perspective.
• Tradeoff-aware security engineering.
• Defensive and educational focus.

What You Will Find

Each case study is built as a repeatable analysis unit with:

• architecture context
• failure mode and abuse path
• operational impact and detection signals
• mitigation patterns and tradeoff analysis
• references for verification
