lgkm.org field notes: Architecture and strategy The state of modern IT and security https://lgkm.org/topics/architecture/ 2026-10-26T00:00:00Z Simon Bennett Post-quantum migration starts with a cryptography inventory https://lgkm.org/notes/post-quantum-starts-with-inventory/ 2026-10-26T00:00:00Z The new quantum-safe algorithms are standard and the deadlines are set: 2028 to know what you have, 2035 to finish. The hard part is not the maths. It is finding every place an organisation uses cryptography, and most cannot list them yet. Security runs on pub-sub: the mesh, the logs and the monitoring https://lgkm.org/notes/security-runs-on-pub-sub/ 2026-10-18T00:00:00Z Most of what makes a security architecture work is one pattern in disguise, publish and subscribe. Seeing it explains why logging, monitoring and the mesh succeed or fail together. Where security architecture stands, and why most organisations run several at once https://lgkm.org/notes/where-security-architecture-stands/ 2026-10-18T00:00:00Z Security architecture has moved through seven stages, from ad hoc to AI-native. Most organisations live in several at once, and that mix is the real starting point.
