HashiCorp Vault policies form the backbone of your Vault security model. They grant or restrict access to specific paths and actions, ensuring that users and applications only perform allowed operations. In this section, you’ll learn how to define, structure, and apply Vault policies to meet real-world requirements.
Vault policies can be written in HCL (HashiCorp Configuration Language) or JSON. For complete syntax details, refer to the Vault Policy Documentation.
