What it means
A managed secrets system can encrypt values, control access, audit retrieval, rotate credentials, and deliver them at runtime without placing them in source code or images.
Why it matters
Secrets often unlock other systems, so poor storage or excessive lifetime can turn one code leak into broad cloud compromise.
Practical focus
- Remove secrets from code, templates, images, and logs
- Use workload identity to retrieve secrets at runtime
- Rotate values and test dependent applications
- Monitor unusual retrieval and administrative changes
Common mistakes
- Storing encrypted secrets beside the decryption key
- Rotating credentials without application testing
- Giving every workload access to one shared secret store
