Encrypt sensitive information at rest |
Customer |
Use encryption at rest on all Azure resources. Microsoft recommends allowing Azure to manage your encryption keys, however there is the option for you to manage your own keys in some instances.

Encrypt sensitive data at rest |
Shared |
To complement access controls, data at rest should be protected against ‘out of band’ attacks (such as accessing underlying storage) using encryption. This helps ensure that attackers cannot easily read or modify the data.
Azure provides encryption for data at rest by default. For highly sensitive data, you have options to implement additional encryption at rest on all Azure resources where available. Azure manages your encryption keys by default, but Azure provides options to manage your own keys (customer managed keys) for certain Azure services.

Use customer-managed key option in data at rest encryption when required |
Shared |
**Security Principle:**
If required for regulatory compliance, define the use case and service scope where customer-managed key option is needed. Enable and implement data at rest encryption using customer-managed key in services.
**Azure Guidance:**
Azure also provides encryption option using keys managed by yourself (customer-managed keys) for certain services. However, using customer-managed key option requires additional operational efforts to manage the key lifecycle. This may include encryption key generation, rotation, revoke and access control, etc.

Ensure SQL server's TDE protector is encrypted with BYOK (Use your own key) |
Shared |
The customer is responsible for implementing this recommendation. |
TDE with BYOK support provides increased transparency and control over the TDE Protector, increased security with an HSM-backed external service, and promotion of separation of duties.
With TDE, data is encrypted at rest with a symmetric key (called the database encryption key) stored in the database or data warehouse distribution. To protect this data encryption key (DEK) in the past, only a certificate that the Azure SQL Service managed could be used. Now, with BYOK support for TDE, the DEK can be protected with an asymmetric key that is stored in the Key Vault. Key Vault is a highly available and scalable cloud-based key store which offers central key management, leverages FIPS 140-2 Level 2 validated hardware security modules (HSMs), and allows separation of management of keys and data, for additional security.
Based on business needs or criticality of data/databases hosted a SQL server, it is recommended that the TDE protector is encrypted by a key that is managed by the data owner (BYOK). |

Cryptography can be employed to support many security solutions including the protection of controlled unclassified information, the provision of digital signatures, and the enforcement of information separation when authorized individuals have the necessary clearances for such information but lack the necessary formal access approvals. Cryptography can also be used to support random number generation and hash generation. Cryptographic standards include FIPSvalidated cryptography and/or NSA-approved cryptography. |

When encryption is applied to media or media residing within IT equipment it provides an additional layer of defence. Whilst such measures do not reduce or alter the classification of the information itself, physical storage, handling and transfer requirements may be reduced to those of a lesser classification for the media or equipment (but not the data itself). |

If an agency wishes to use encryption to reduce the storage or physical transfer requirements for IT equipment or media that contains classified information, they SHOULD use:
full disk encryption; or
partial disk encryption where the access control will only allow writing to the encrypted partition holding the classified information. |

A financial institution must ensure cryptographic controls are based on the effective implementation of suitable cryptographic protocols. The protocols shall include secret and public cryptographic key protocols, both of which shall reflect a high degree of protection to the applicable secret or private cryptographic keys. The selection of such protocols must be based on recognised international standards and tested accordingly. Commensurate with the level of risk, secret cryptographic key and private-cryptographic key storage and encryption/decryption computation must be undertaken in a protected environment, supported by a hardware security module (HSM) or trusted execution environment (TEE). |

inventories, classifies, and manages information assets.
• Restricts Logical Access — Logical access to information assets, including hardware, data (at-rest, during processing, or in transmission), software, administrative
authorities, mobile devices, output, and offline system components is restricted
through the use of access control software and rule sets.
• Identifies and Authenticates Users — Persons, infrastructure, and software are
identified and authenticated prior to accessing information assets, whether locally
or remotely.
• Considers Network Segmentation — Network segmentation permits unrelated portions of the entity's information system to be isolated from each other.
• Manages Points of Access — Points of access by outside entities and the types of
data that flow through the points of access are identified, inventoried, and managed. The types of individuals and systems using each point of access are identified,
documented, and managed.
• Restricts Access to Information Assets — Combinations of data classification, separate data structures, port restrictions, access protocol restrictions, user identification, and digital certificates are used to establish access-control rules for information assets.
• Manages Identification and Authentication — Identification and authentication requirements are established, documented, and managed for individuals and systems
accessing entity information, infrastructure, and software.
• Manages Credentials for Infrastructure and Software — New internal and external
infrastructure and software are registered, authorized, and documented prior to being granted access credentials and implemented on the network or access point.
Credentials are removed and access is disabled when access is no longer required
or the infrastructure and software are no longer in use.
• Uses Encryption to Protect Data — The entity uses encryption to supplement other
measures used to protect data at rest, when such protections are deemed appropriate based on assessed risk.
• Protects Encryption Keys — Processes are in place to protect encryption keys during generation, storage, use, and destruction |
