• It also keeps a record of who accessed what information for auditing purposes. Additionally, Vault can store encryption keys or certificates securely. Using Vault can help keep your organization’s sensitive data safe and organized.

Why use HashiCorp Vault?

Why use it over Azure Key Vault or AWS KMS?

Platform Agnostic:

• One key advantage of using HashiCorp Vault for secrets management is that it is not tied to any particular cloud platform. You can host Vault wherever you want, including on your own data center or laptop.
• This flexibility is particularly useful for developers who may need to work offline or in disconnected environments. With Vault, you don’t need an internet connection, account, or cloud subscription to get started.

Extensible Architecture:

• Vault uses the concept of “secrets engines” to interface directly with physical systems like databases, HSMs, and other security devices.
• This allows Vault to support a wide range of use cases, including dynamic SQL user creation, AWS IAM, and more. And because all of these systems are accessed through the same read/write interface, Vault makes it easy to manage secrets consistently across your entire organization.

Comprehensive Security:

• Finally, Vault offers comprehensive security features that make it a strong choice for organizations with demanding security requirements. Vault supports multiple authentication methods, including tokens, usernames and passwords, and external providers like Azure AD.
• It also provides a detailed audit trail of all secret access and usage, so you can track who is accessing your sensitive data and when. Additionally, Vault can store encryption keys and certificates securely, adding another layer of protection for your secrets.

Authentication and Access Management

Vault can process client requests only after the Unseal operation is completed. When the client connects to Vault for the first time, it needs to complete authentication first. The authentication methods of the client are:

• Suitable for users: username/password, LDAP authentication, etc., and users need to be granted appropriate permissions to access Vault
• Suitable for application: Public/Private keys, Tokens or JWT Token, etc.

The general process is as follows:

1. The client initiates an authentication request, which flows through the Core module and in Auth methods, it determines if the request is valid and returns a list of associated policies. After the authentication is completed and the checked association policy is confirmed, a new Token will be generated and managed, and this Token will be returned to the client for subsequent requests. It should be noted that this token also has a lease period (validity period), and the token is associated with related policies, Policies, which will be used to verify the requested permissions.
2. After the request is authenticated, it will be routed to the Secret engine module . If a Secret is Secret engine returned (the one auto-generated by Vault), it will be registered with it Expiration manager, and one will be attached to it lease ID. lease ID is used by the client to update (Renew) or revoke (Revoke) the Secret it got. If the client allows the lease (Lease) to expire, the Secret will be automatically revoked by the Expiration manager .

Secret Engine

Secret Engine is a component of the Vault system that saves, generates, or encrypts data. Similar to a virtual file system, all write/delete/list/read operations are performed under it, and then you can decide how to respond to requests.

Commonly used Engines are as follows:

• kv: key-value store. It can be think as an encrypted Redis, which simply stores/reads some static configuration data
• Transit Secrets Engine: Provides the function of encryption as a service, and is only responsible for encryption and decryption, not storage
• Certificate management: The most common scenario is to store the root certificate (root) in the Vault, and the business certificate is issued through this Engine
