What is Secret Management?
Securely storing and distributing credentials, API keys, and certificates. Tools like Vault, AWS Secrets Manager, and SOPS prevent secrets from leaking into code or logs.
Secret Management is a intermediate-level concept that sits in the Security Architecture area of system design. Engineers reach for it whenever they need to reason about real-world trade-offs in that space — not just for textbook correctness, but because real production systems at companies like Netflix, Amazon, and Google make these decisions every day.
If you want to go deeper than this definition — with diagrams, code, and a quiz to lock it in — work through the "Secret Management" lesson linked below. It walks through the why, the mechanism, the trade-offs, and how the giants actually use it in production.

Data Encryption
Transforming data into an unreadable format using cryptographic algorithms. Encryption at rest protects stored data; encryption in transit protects data over the network.
API Key
A simple token passed with API requests to identify the calling project or application. Not a substitute for user authentication but useful for rate limiting and usage tracking.
Zero Trust
A security model that never trusts any request by default, even from inside the network. Every request must be authenticated, authorized, and encrypted regardless of origin.
