3. Vault Fundamentals

The Vault Fundamentals section is at the core of the HashiCorp Vault Associate Certification exam. This section will test your understanding of the foundational concepts of Vault, such as its architecture, secret management, and encryption handling. A strong grasp of these topics is essential for effectively using Vault to manage secrets securely. Below are some critical topics that you should be prepared to discuss and understand:

1. How Vault is Sealed and Unsealed Using Shamir’s Secret Sharing Algorithm

Vault’s sealing and unsealing process is an important security feature, designed to protect sensitive data. Vault uses Shamir’s Secret Sharing Algorithm to ensure that no single individual or entity has complete access to the vault’s contents. Here’s how this process works:

• Sealed State: When Vault is sealed, it is in a read-only state, and no operations can be performed on it. Sealing is necessary to ensure that Vault cannot perform any operations (e.g., serving secrets or accepting changes) until it is unsealed.
• Unsealing Vault: To unseal Vault, a certain number of unseal keys (as determined by the Shamir algorithm) are required. Vault’s unseal process involves a threshold number of key shares being combined, but no single key holder can unseal the Vault alone. This mechanism helps enhance security by ensuring that access to the Vault is only possible when multiple trusted parties are involved.
  • Shamir’s Secret Sharing: This cryptographic algorithm splits a secret (the unseal key) into multiple shares. A minimum number of shares (the threshold) must be combined to reconstruct the secret and unseal Vault. For example, if you have 5 shares and a threshold of 3, any 3 shares are needed to unseal the Vault.

This design ensures that the process of unsealing Vault is secure and controlled, especially in high-stakes environments where secret access must be tightly controlled.

2. Understanding Auto Unseal Functionality

Vault provides the Auto Unseal functionality, which simplifies the unsealing process by automatically unsealing the Vault when it starts. This feature can be particularly useful in automated environments where manual intervention is not feasible, such as when deploying Vault in a Kubernetes cluster or a cloud-based environment.

• How Auto Unseal Works: When Vault is configured with Auto Unseal, Vault can automatically unseal itself using an external key management system (KMS). These KMS systems include cloud services like AWS KMS, Azure Key Vault, or Google Cloud KMS. When Vault starts, it communicates with the KMS to retrieve the unseal key, eliminating the need for manual unsealing.

• Benefits of Auto Unseal:
  • It reduces operational overhead and eliminates human intervention during the unsealing process.
  • It ensures that Vault can be automatically unsealed and made operational as soon as it starts, even in environments with dynamic workloads.
  • It simplifies the recovery process in the event of Vault failure or restarts, which is particularly useful in high-availability or disaster recovery scenarios.

However, this convenience comes at a cost. It requires additional configuration and trust in the KMS, which will hold the unseal key material. This makes Auto Unseal suitable primarily for cloud or high-availability deployments where security is managed by trusted third-party KMS providers.

3. The Difference Between the Vault Storage Backend and Cryptographic Components

Vault relies on two essential components for operation: the storage backend and the cryptographic components. While they both contribute to Vault’s ability to secure and manage secrets, they serve distinct functions:

Vault Storage Backend

• The storage backend is responsible for persisting data, such as secrets, policies, leases, and other metadata. It ensures that data is stored securely and can be retrieved when needed.
• Types of Storage Backends: Vault supports various storage backends, such as Consul, Amazon S3, Google Cloud Storage, Cassandra, and more. Each backend has its own strengths and is chosen based on the operational requirements (e.g., scalability, reliability, or speed).
• Purpose: The storage backend’s primary purpose is to persist Vault’s state, including the secrets and their associated metadata. It does not hold the sensitive data itself in an unencrypted form but stores encrypted data that can only be decrypted by Vault’s cryptographic components.
• Configuration: The storage backend can be configured during Vault’s installation and initialization phase. You will need to select a backend that suits your architecture, such as choosing Consul for highly available deployments or S3 for cloud environments.

Cryptographic Components

• The cryptographic components of Vault are responsible for securing secrets and performing operations like encryption and decryption. Vault uses strong encryption algorithms to ensure that data stored in its system is protected and remains confidential.
• Encryption at Rest: All secrets stored in Vault are encrypted at rest. Vault’s AES-256 encryption ensures that even if someone gains unauthorized access to the storage backend, they will not be able to read or manipulate the secrets because the data is stored in an encrypted format.
• Encryption in Transit: Vault also uses TLS (Transport Layer Security) to ensure that data is encrypted in transit when being sent to and from Vault’s services. This prevents any data from being intercepted during communication.
• Sealing and Unsealing: The cryptographic components also play a role in sealing and unsealing Vault. When Vault is sealed, the cryptographic keys are removed from memory, and when it is unsealed, the keys are restored for encryption and decryption operations.
• Encryption-as-a-Service: Vault’s cryptographic functionality extends beyond secret management to provide services like encryption and decryption without storing the data. This is particularly useful for applications that require encryption but don’t want to manage their own encryption keys.

4. Authentication Methods

Vault offers multiple authentication methods for access control, and you’ll need to know how to configure and use them both via the CLI and the UI. Focus on:

• Enabling and managing authentication methods.
• Understanding and customizing the mount points for these methods.
• Practical experience configuring Auth methods and understanding their lifecycle.

5. Vault Tokens and Access Control

The certification will test your knowledge of Vault tokens, including how to manage them, renew, and revoke them. It’s also important to understand token accessors, policies, and associated security principles like TTL (Time To Live).

Key topics include:

• How to generate, renew, and revoke tokens.
• The role of tokens in managing secret access and Vault sessions.
• How to configure policies to define token capabilities.

6. Encryption Services

Vault provides Encryption as a Service (EaaS), which will likely be featured in the exam. You’ll need to understand:

• How Vault encrypts and decrypts data in transit.
