📚 Welcome to Day 31 – PART 1!
In this session, we build the foundations for understanding secure communication—both inside and outside Kubernetes. We’ll start with the basics: client-server architecture, mutual authentication in SSH, and how TLS enables secure web access. Then we demystify Certificate Authorities, including the difference between trusted public CAs, private CAs, and self-signed certificates.
📝 What We’ll Cover:
✅ What are client and server in networking
✅ SSH: Mutual authentication using public key cryptography
✅ 1-Way TLS explained with TLS 1.3
✅ Certificate Authorities: Public vs Private vs Self-Signed
💡 By the end of this part:
You’ll clearly understand how identity and trust are established in secure protocols like SSH and TLS, and how different types of CAs fit into real-world infrastructure and Kubernetes setups.
