Azure Key Vault is a centralized service that allows users to manage their encryption keys, secrets, and certificates. To enable key rotation for keys stored in Azure Key Vault:
For Azure Storage Accounts, rotating keys involves periodically changing the storage account keys:
Azure SQL Database, Cosmos DB, and many other services that use encryption also support key rotation. The general principles for key rotation with these services are similar:
When planning for key rotation, consider the following best practices:
Remember that while Azure provides tools and features to support key rotation, following these practices will enhance your overall security posture and will demonstrate a thorough understanding of configuring key rotation, which is essential for candidates preparing for the AZ-500 Microsoft Azure Security Technologies exam.
Automatic key rotation is not supported for all types of cryptographic keys in Azure. Azure Key Vault allows you to manually rotate keys by creating a new version of the key, but the process is not automatic for all key types.
Azure Key Vault supports manual key rotation. Users can create a new version of a key to effectively rotate it, thus changing the material of the key while keeping the same key identifier.
Answer: A, B, C
Key rotation is recommended after a key compromise, as part of regular security hygiene/practices in line with organizational policy, and after an employee who had access to the key leaves the company. While transitioning from test to production might involve many security practices, key rotation isn’t specifically a requirement unless the keys from the test environment were compromised or shouldn’t be used in production for security reasons.
Azure does not automatically rotate storage account keys by default. Users can manually rotate these keys or automate the rotation themselves using Azure Automation, Azure Functions, or other automation solutions.
Answer: A, B, D
Key type and usage, regulatory compliance requirements, and lifecycle management policy should all be considered when configuring key rotation. The physical storage location of the key (coordinates) is not directly relevant to the rotation process itself.
Azure Policy can be used to enforce certain governance conditions, including the rotation of keys within a set period, by applying specific policy definitions that audit or enforce these practices.
Answer: A
Azure Automation is a service that can be used to automate repetitive and complex tasks, such as the rotation of keys and secrets within Azure Key Vault.
Key rotation in Azure does not require downtime or service interruption. Key Vault enables you to create new versions of a key, and applications can be designed to use the latest version without interruption.
Answer: C
Azure Key Vault is the tool that helps with managing the lifecycle of keys, secrets, and certificates, including their rotation.
It is a best practice to have uniform access policies for all versions of a key in Azure Key Vault so that applications using the key do not encounter unexpected access issues when a new key version is introduced.
Answer: A
Azure Monitor can be used to track and monitor operations, including key rotation events within the Azure Key Vault.
Azure Key Vault allows for the rotation of keys by creating new key versions without changing the key identifier. This helps simplify key management for applications that reference these keys for encryption and decryption operations.
Keys in Azure Key Vault are cryptographic keys used to encrypt and decrypt data, as well as to digitally sign and verify data.
Keys should be rotated periodically according to your organization’s security policies, typically every 6-12 months.
Key rotation is the process of replacing existing keys with new ones to enhance the security of your data.
You can enable key rotation for keys in Azure Key Vault by setting the “EnableSoftDelete” and “EnablePurgeProtection” properties to true.
Secrets rotation is the process of periodically changing the values of secrets stored in Azure Key Vault to enhance their security.
You can rotate a secret in Azure Key Vault by creating a new version of the secret with the updated value, and then updating the application to use the new version.
Certificate rotation is the process of periodically renewing or replacing digital certificates to ensure the continued security of your applications.
You can enable certificate rotation in Azure Key Vault by configuring a certificate policy that specifies the desired settings for certificate expiration, renewal, and replacement.
Key-rotation log monitoring in Azure Key Vault provides visibility into key rotation events, including the creation, rotation, and deletion of keys, and can help identify and troubleshoot issues related to key rotation.
Secrets rotation in Azure Key Vault helps prevent unauthorized access to sensitive data by periodically changing the values of secrets used by your applications.
