Cyber security is a process, not a destination to arrive at. Designing a cyber security architecture for your use case is the process of choosing between “less safe” and “more safe” and continuing this process until you reach “safe enough” for the information you want to protect.

1 If you’re not using SSH certificates you’re doing SSH wrong

SSH is great and a must use for unix system administration. But using SSH is as with any tool no guaranty for ultimate security. Reading this blog made me think: Should I write better SSH tutorial? Maybe in future, but know that the best guide for doing SSH correct is still using the great ssh man pages!

2 Implementing a toy version of TLS 1.3

Anyone who claims to fully understand TLS 1.3 and PKI should not be trusted. Real experts know that the complexity of programming, cryptography, PKI and tcp requires multiple subject matter experts that can really cooperate. TLS 1.3 is constantly evolving. This blog touches some aspects when playing with TLS 1.3.

4 Germany’s Cybersecurity Architecture

This is a must read if you want detailed and complete information on Germans Security. The overview page is nice and clickable. The report (I read the English version) is great with many nice resources included. A country’s cybersecurity architecture includes all actors, government agencies, platforms, organizations, that are part of the ecosystem.
