Azure KeyVault Secrets: Manage and Protect Your Data

Azure KeyVault Secrets is a robust and secure way to store and manage sensitive data. It provides a centralized repository for storing secrets, such as API keys, connection strings, and certificates.

You can store up to 4 KB of data in a single secret. This is sufficient for most use cases, but you can always use Azure Blob Storage if you need to store larger amounts of data.

Azure KeyVault Secrets integrates seamlessly with Azure services, such as Azure App Service and Azure Functions. This makes it easy to use secrets in your applications without having to worry about security.

To get started with Azure KeyVault Secrets, you'll need to create a KeyVault instance and then create a secret within it. This can be done through the Azure portal or using the Azure CLI.

You can add a secret to Key Vault by navigating to your key vault in the Azure portal, selecting Secrets, and then clicking + Generate/Import.

To create a new secret, choose the following values on the Create a secret screen: name, value, and tags. Once you receive the message that the secret has been successfully created, you may select it on the list.

To retrieve a secret from Key Vault, you can use Azure CLI, Azure PowerShell, or the get_secret command. This retrieves a secret previously stored in the Key Vault.

Secrets can be retrieved asynchronously using the list_properties_of_secrets command, which lists the properties of all the secrets in the client's vault without including the secret values.

Here are the steps to configure KSSCD to make key vault secrets available locally:

1. Create a Kubernetes SecretProviderClass resource.

2. Customize the YAML file to query the Azure Key Vault objects and make their values available inside the namespace in a new Kubernetes secret.

Note that it is possible to create multiple Kubernetes secrets under secretObjects, and populate them with different keys and values.

Tags are a crucial part of working with secrets in Azure Key Vault, allowing you to store application-specific metadata.

You can specify up to 15 tags, each with a 512 character name and a 512 character value.

Tags are best used for storing information required for management, such as rotation configuration.

For example, you can store credential information in secret values and use tags to store related information.

The Kubernetes Secrets Store CSI Driver, or KSSCD, is a tool that connects to a vault, pulls one or multiple secrets from it, and makes them available inside the Kubernetes cluster.

KSSCD is able to query secrets from many different types of vaults, including Azure Key Vault.

To use KSSCD, you'll need to create an identity for granting KSSCD access to the vault.

KSSCD must be installed in the cluster and configured to know which vault secrets to query and which Kubernetes secret(s) to create from them.

Here are the steps to follow:

Retrieving secrets from a vault is a crucial step in working with secrets. You can use Azure CLI or Azure PowerShell to retrieve previously created secrets.

To get started, you'll need to know how to use the Azure CLI or Azure PowerShell commands. For example, you can use the `get_secret` command to retrieve a secret previously stored in the Key Vault.

There are several ways to retrieve secrets from a vault, including using the Azure CLI or Azure PowerShell. You can also use the `list_properties_of_secrets` command to list the properties of all the secrets in your vault.

Here are some common ways to retrieve secrets from a vault:

Once you've retrieved your secret, you can use it in your application or service. Remember to store your secrets securely and never hardcode them into your code.

Updating metadata is a crucial step in managing secrets. This process is handled by the update_secret_properties function.

This function updates a secret's metadata, but it's essential to note that it can't change the secret's value. That's what the set_secret function is for.

You can use update_secret_properties to modify the secret's metadata as needed. For example, you can update the secret's name or description.

It's worth mentioning that update_secret_properties can't change the secret's value, so be sure to use set_secret if you need to update the secret's actual content.

Security and Access is a top priority when it comes to Azure Key Vault secrets. You can control access to your secrets by creating a Key Vault access policy, which is distinct from the access policy for keys in the same Key Vault.

To control access, you can use permissions such as secret management operations and privileged operations, on a per-principal basis, in the secrets access control entry on a vault.

You can also use Azure role-based access control to provide access to Key Vault keys, certificates, and secrets. This can be done by assigning a Key Vault access policy using the Azure portal, PowerShell, or CLI.

Here are some ways to control access in Key Vault:

Encryption is a top priority for Azure Key Vault, and it's handled transparently behind the scenes. All secrets in your Key Vault are stored encrypted, with a hierarchy of encryption keys that are protected by modules that are FIPS 140-2 compliant.

The encryption leaf key of the key hierarchy is unique to each key vault, while the encryption root key is unique to the security world and its protection level varies between regions.

In China, the root key is protected by a module that is validated for FIPS 140-2 Level 1, while in other regions, it's protected by a module that is validated for FIPS 140-2 Level 2 or higher.

Azure Key Vault encrypts your secrets when you add them, and decrypts them automatically when you read them, making it a seamless and secure process.

Access Control is a crucial aspect of Key Vault security. It's essential to understand how to manage access to your secrets and keys to prevent unauthorized access.

You can create separate vaults to hold secrets and maintain scenario-appropriate segmentation and management of secrets. This is a good practice to follow.

To control access to secrets, you can use permissions such as secret management operations and privileged operations. These permissions can be used on a per-principal basis in the secrets access control entry on a vault.

Here are some key facts to keep in mind when it comes to access control:

To assign access policies, you can use the Azure CLI, PowerShell, or the Azure portal. You can also use Azure role-based access control to provide access to Key Vault keys, certificates, and secrets.

It's essential to follow least privileged access by only having access to read secrets. Access to secrets can be controlled either with access policies or with Azure role-based access control.

To reduce exposure, you can specify which IP addresses have access to your vaults and configure your firewall to only allow applications and related services to access secrets in the vault.

File hashes are a crucial aspect of ensuring the integrity and authenticity of files. They provide a unique digital fingerprint of a file, allowing you to verify its contents and ensure it hasn't been tampered with.

The hashes for the azure_keyvault_secrets-4.9.0.tar.gz file are provided, including SHA256, MD5, and BLAKE2b-256 algorithms. These hashes are 2a03bb2ffd9a0d6c8ad1c330d9d0310113985a9de06607ece378fd72a5889fe1, 137e3d137cbf93642a253caf03329b05, and 5153188681c8b7ec49b6945605efdb91ec9a86ebfa77f8eab8b9a50f458c504a, respectively.

The SHA256 hash for the azure_keyvault_secrets-4.9.0-py3-none-any.whl file is 33c7e2aca2cc2092cebc8c6e96eca36a5cc30c767e16ea429c5fa21270e9fba6. This hash can be used to verify the file's contents and ensure it hasn't been altered.

Here are the hash algorithms and their corresponding digests for both files:

By using these hashes, you can ensure the integrity and authenticity of the azure_keyvault_secrets-4.9.0.tar.gz and azure_keyvault_secrets-4.9.0-py3-none-any.whl files.

Monitoring is crucial to ensure the security and access of your secrets. You can turn on Key Vault logging to keep track of access to your secrets and their lifecycle.

Azure Monitor is a powerful tool that allows you to monitor all secrets activities in all your vaults in one place. This can help you stay on top of any potential security issues.

You can also use Azure Event Grid to monitor the lifecycle of secrets, which has easy integration with Azure Logic Apps and Azure Functions. This can help you automate tasks and notifications related to secret management.

Azure Key Vault can be set up as an Event Grid source, allowing you to receive notifications and trigger actions based on secret-related events.
