[Preview]: Azure Key Vault Managed HSM should disable public network access Disable public network access for your Azure Key Vault Managed HSM so that it's not accessible over the public internet. This can reduce data leakage risks. Learn more at: https://docs.microsoft.com/azure/key-vault/managed-hsm/private-link#allow-trusted-services-to-access-managed-hsm. Audit, Deny, Disabled 1.0.0-preview
[Preview]: Azure Key Vault Managed HSM should use private link Private link provides a way to connect Azure Key Vault Managed HSM to your Azure resources without sending traffic over the public internet. Private link provides defense in depth protection against data exfiltration. Learn more at: https://docs.microsoft.com/azure/key-vault/managed-hsm/private-link Audit, Disabled 1.0.0-preview

Key Vault keys should have an expiration date Cryptographic keys should have a defined expiration date and not be permanent. Keys that are valid forever provide a potential attacker with more time to compromise the key. It is a recommended security practice to set expiration dates on cryptographic keys. Audit, Deny, Disabled 1.0.2
Key Vault secrets should have an expiration date Secrets should have a defined expiration date and not be permanent. Secrets that are valid forever provide a potential attacker with more time to compromise them. It is a recommended security practice to set expiration dates on secrets. Audit, Deny, Disabled 1.0.2
Key Vault should use a virtual network service endpoint This policy audits any Key Vault not configured to use a virtual network service endpoint. Audit, Disabled 1.0.0
Key vaults should have deletion protection enabled Malicious deletion of a key vault can lead to permanent data loss. You can prevent permanent data loss by enabling purge protection and soft delete. Purge protection protects you from insider attacks by enforcing a mandatory retention period for soft deleted key vaults. No one inside your organization or Microsoft will be able to purge your key vaults during the soft delete retention period. Keep in mind that key vaults created after September 1st 2019 have soft-delete enabled by default. Audit, Deny, Disabled 2.1.0
Key vaults should have soft delete enabled Deleting a key vault without soft delete enabled permanently deletes all secrets, keys, and certificates stored in the key vault. Accidental deletion of a key vault can lead to permanent data loss. Soft delete allows you to recover an accidentally deleted key vault for a configurable retention period. Audit, Deny, Disabled 3.0.0
Keys should be backed by a hardware security module (HSM) An HSM is a hardware security module that stores keys. An HSM provides a physical layer of protection for cryptographic keys. The cryptographic key cannot leave a physical HSM which provides a greater level of security than a software key. Audit, Deny, Disabled 1.0.1
Keys should be the specified cryptographic type RSA or EC Some applications require the use of keys backed by a specific cryptographic type. Enforce a particular cryptographic key type, RSA or EC, in your environment. Audit, Deny, Disabled 1.0.1
Keys should have a rotation policy ensuring that their rotation is scheduled within the specified number of days after creation. Manage your organizational compliance requirements by specifying the maximum number of days after key creation until it must be rotated. Audit, Disabled 1.0.0
Keys should have more than the specified number of days before expiration If a key is too close to expiration, an organizational delay to rotate the key may result in an outage. Keys should be rotated at a specified number of days prior to expiration to provide sufficient time to react to a failure. Audit, Deny, Disabled 1.0.1
Keys should have the specified maximum validity period Manage your organizational compliance requirements by specifying the maximum amount of time in days that a key can be valid within your key vault. Audit, Deny, Disabled 1.0.1
Keys should not be active for longer than the specified number of days Specify the number of days that a key should be active. Keys that are used for an extended period of time increase the probability that an attacker could compromise the key. As a good security practice, make sure that your keys have not been active longer than two years. Audit, Deny, Disabled 1.0.1
Keys using elliptic curve cryptography should have the specified curve names Keys backed by elliptic curve cryptography can have different curve names. Some applications are only compatible with specific elliptic curve keys. Enforce the types of elliptic curve keys that are allowed to be created in your environment. Audit, Deny, Disabled 1.0.1
Keys using RSA cryptography should have a specified minimum key size Set the minimum allowed key size for use with your key vaults. Use of RSA keys with small key sizes is not a secure practice and doesn't meet many industry certification requirements. Audit, Deny, Disabled 1.0.1
Resource logs in Azure Key Vault Managed HSM should be enabled To recreate activity trails for investigation purposes when a security incident occurs or when your network is compromised, you may want to audit by enabling resource logs on Managed HSMs. Please follow the instructions here: https://docs.microsoft.com/azure/key-vault/managed-hsm/logging. AuditIfNotExists, Disabled 1.1.0
Resource logs in Key Vault should be enabled Audit enabling of resource logs. This enables you to recreate activity trails to use for investigation purposes when a security incident occurs or when your network is compromised AuditIfNotExists, Disabled 5.0.0

Secrets should have more than the specified number of days before expiration If a secret is too close to expiration, an organizational delay to rotate the secret may result in an outage. Secrets should be rotated at a specified number of days prior to expiration to provide sufficient time to react to a failure. Audit, Deny, Disabled 1.0.1
Secrets should have the specified maximum validity period Manage your organizational compliance requirements by specifying the maximum amount of time in days that a secret can be valid within your key vault. Audit, Deny, Disabled 1.0.1
Secrets should not be active for longer than the specified number of days If your secrets were created with an activation date set in the future, you must ensure that your secrets have not been active for longer than the specified duration. Audit, Deny, Disabled 1.0.1
