To implement TDE in Azure SQL Database, you need to follow these steps:
-
Create a server-level firewall rule to allow traffic from Azure services. This is necessary because the encryption process is performed by an Azure service.
-
Create a server certificate or use an existing one.
-
Create a database encryption key (DEK) in the master database.
-
Encrypt the DEK with the server certificate.
-
Enable TDE for the database.
Once TDE is enabled, the database files are encrypted at rest. When a user or application connects to the database, the data is automatically decrypted, so there is no impact on the application.
It's important to note that TDE only encrypts the database files at rest. If you need to encrypt data in transit, you will need to use other encryption methods, such as SSL or TLS.
Azure SQL Database Always Encrypted should be used when there is a requirement to protect sensitive data such as personally identifiable information (PII) or financial information from unauthorized access or data breaches. With Always Encrypted, sensitive data is encrypted at rest, in transit, and in use, providing end-to-end encryption and minimizing the risk of data breaches. The encryption keys are managed outside of the database, and only authorized parties have access to the keys, making it more difficult for attackers to gain access to the sensitive data. Always Encrypted is particularly useful for scenarios where third-party applications or services need to access the database, but the database owner wants to ensure that sensitive data is protected even if the third-party system is compromised.
• Azure Policy is a service in Azure that allows you to create, assign, and manage policies that enforce rules and effects over resources in Azure.

• Access to Azure Key Vault resources can be controlled using two main methods: Azure RBAC and Vault Access Policies.
• Azure RBAC is used to grant permissions at the subscription, resource group, or resource level. You can assign roles to users, groups, or applications to control what they can do within Azure Key Vault. For example, you can grant a user the "Key Vault Contributor" role to allow them to manage keys and secrets in a specific key vault.
• Vault Access Policies are used to control access to individual keys, secrets, and certificates within a key vault. You can create access policies to grant permissions to specific users, groups, or applications for specific keys, secrets, or certificates. For example, you can create an access policy to grant a specific application the ability to read a secret value from a key vault.
• When creating a new access policy, you can specify the permissions (such as get, list, set, delete) that are granted to the principal (user, group, or application). You can also specify whether the principal can manage the key vault itself, or just the specific resource within the key vault.
• Azure Key Vault also supports Azure AD authentication, which allows users to authenticate using their Azure AD credentials instead of using a key or certificate. You can configure Azure AD authentication when creating the key vault or by updating the key vault settings later.
• Azure Key Vault also supports firewall rules, which allow you to control which IP addresses or ranges can access the key vault over the internet. You can create firewall rules when creating the key vault or by updating the key vault settings later.
• When configuring access to Azure Key Vault, it's important to follow the principle of least privilege, which means granting only the necessary permissions to users, groups, or applications to perform their intended tasks. This helps minimize the risk of unauthorized access to sensitive data or resources.
• Azure Key Vault can be used to manage and store certificates, secrets, and keys. These can include SSL/TLS certificates, API keys, passwords, and cryptographic keys for data encryption and decryption.
• To manage certificates, you can import certificates into Azure Key Vault or generate a new certificate using a certificate signing request (CSR). You can also configure certificate renewal settings to ensure that certificates are automatically renewed before they expire.
• To manage secrets, you can store sensitive data such as connection strings, passwords, and API keys in Azure Key Vault. Secrets can be created and updated programmatically using Azure Key Vault APIs or through the Azure portal.
• To manage keys, you can create and store cryptographic keys in Azure Key Vault. Keys can be generated using various algorithms such as RSA, AES, and elliptic curve cryptography (ECC). You can also import existing keys into Azure Key Vault or use Azure Key Vault to generate new keys.
• Azure Key Vault supports various cryptographic operations such as encrypting and decrypting data using keys, signing and verifying data using keys, and wrapping and unwrapping keys. These operations can be performed programmatically using Azure Key Vault APIs or through the Azure portal.
• Azure Key Vault also provides features for key rotation, versioning, and backup and restore. Key rotation allows you to periodically change cryptographic keys to help mitigate the risk of key compromise. Versioning allows you to create multiple versions of a key or certificate to support rolling upgrades and compatibility with legacy applications. Backup and restore allows you to create backups of your keys and certificates to protect against data loss.
• When managing certificates, secrets, and keys in Azure Key Vault, it's important to follow best practices for security and compliance, such as using strong encryption algorithms, enforcing access controls, and monitoring key usage and access.
• Key rotation is the process of regularly changing cryptographic keys to help mitigate the risk of key compromise. It is an important security practice for managing cryptographic keys.
• Azure Key Vault supports key rotation for managing keys, certificates, and secrets. You can configure key rotation for a key vault, a specific key or certificate, or a specific secret.
• To configure key rotation for a key vault, you can enable the key vault's "Soft Delete" feature, which allows you to recover deleted keys and enables key versioning. You can also configure a retention period for deleted keys to help prevent accidental deletion.
• To configure key rotation for a specific key or certificate, you can set a rotation policy that specifies the interval at which the key or certificate should be rotated. The rotation policy can be set to a specific number of days or a specific date and time.
• When a key or certificate is rotated, a new version of the key or certificate is generated and the old version is marked as inactive. The new version can then be used for encrypting or decrypting data or for signing and verifying data.
• When rotating keys or certificates, it's important to consider the impact on applications that use the keys or certificates. You may need to update applications to use the new keys or certificates and ensure that old keys or certificates are no longer used.
• Key rotation should be performed on a regular basis, such as every 90 days, to help mitigate the risk of key compromise. This interval can be adjusted based on the level of risk and the sensitivity of the data being protected.
• When configuring key rotation, it's important to follow best practices for security and compliance, such as using strong encryption algorithms, enforcing access controls, and monitoring key usage and access.
• Azure Key Vault provides features for backing up and restoring certificates, secrets, and keys to protect against data loss.
• Backing up certificates, secrets, and keys allows you to create a secure copy of the data that can be used to recover the data in case of accidental deletion, corruption, or other types of data loss.
• To backup a certificate, secret, or key in Azure Key Vault, you can use the Azure portal, Azure CLI, Azure PowerShell, or Azure Key Vault APIs. The backup can be stored in a secure location such as an Azure Storage account or on-premises storage.
• To restore a backed-up certificate, secret, or key, you can use the Azure portal, Azure CLI, Azure PowerShell, or Azure Key Vault APIs. The restored data is returned to the same key vault or to a different key vault.
• When restoring a certificate, secret, or key, a new version of the data is created with a new identifier. This allows you to recover the data without overwriting existing data.
• It's important to secure the backups of certificates, secrets, and keys to prevent unauthorized access. Backups should be encrypted using strong encryption algorithms and stored in a secure location.
• It's also important to regularly test the backup and recovery process to ensure that backups are being created correctly and can be restored in case of a data loss event.
• When configuring backup and recovery of certificates, secrets, and keys, it's important to follow best practices for security and compliance, such as using strong encryption algorithms, enforcing access controls, and monitoring backup and recovery activities.

Source Article by Microsoft https://learn.microsoft.com/en-us/sql/relational-databases/security/encryption/always-encrypted-database-engine?view=sql-server-ver16
This section provides an overview of setting up Always Encrypted. For details and to get started, see Tutorial: Getting started with Always Encrypted.
To set up Always Encrypted in your database, you need to:
Provision cryptographic keys to protect your data. Always Encrypted uses two types of keys:
Column encryption keys.
Column master keys.
A column encryption key is used to encrypt data in an encrypted column. A column master key is a key-protecting key that encrypts one or more column encryption keys.
You need to store column master keys in a trusted key store outside of the database system, such as Azure Key Vault, Windows certificate store, or a hardware security module.
Then, you need provision column encryption keys and encrypt each of them with a column master key.
Finally, you need to store the metadata about the keys in your database.
The column master key metadata captures the location of the column master key. The column encryption key metadata contains the encrypted value of the column encryption key. The Database Engine never stores or uses the keys of either type in plaintext.
For more information about managing Always Encrypted keys, see Overview of key management for Always Encrypted
Configure encryption for selected database columns that contain sensitive data to be protected. This can involve creating new tables with encrypted columns or encrypting existing database columns and existing data. When setting up encryption for a column, you specify the information about an encryption algorithm, a column encryption key to protect the data in the column, and an encryption type. Always Encrypted supports two encryption types:
Deterministic encryption always generates the same encrypted value for a given plaintext value. Using deterministic encryption allows point lookups, equality joins, grouping and indexing on encrypted columns. However, it may also allow unauthorized users to guess information about encrypted values by examining patterns in the encrypted column, especially if there's a small set of possible encrypted values, such as True/False, or North/South/East/West region.
Randomized encryption uses a method that encrypts data in a less predictable manner. Randomized encryption is more secure, but prevents searching, grouping, indexing, and joining on encrypted columns.
Use deterministic encryption for columns that will be used as search or grouping parameters. For example, a government ID number. Use randomized encryption for data such as confidential investigation comments, which aren't grouped with other records and aren't used to join tables.
For details on Always Encrypted cryptographic algorithms, see Always Encrypted cryptography.
You can perform the above steps using SQL tools:
SQL Server Management Studio (SSMS)
sqlpackage - which automate the setup process
To ensure Always Encrypted keys and protected sensitive data are never revealed in plaintext to the database environment, the Database Engine can't be involved in key provisioning and data encryption, or decryption operations. Therefore, Transact-SQL (T-SQL) doesn't support key provisioning or cryptographic operations. For the same reason, encrypting existing data or re-encrypting it (with a different encryption type or a column encryption key) needs to be performed outside of the database (SQL tools can automate that).

Review scope of roles and actions. Understand when things like dataactions [] and actions [] apply and what those differences are. The diagrams are useful as a reference to understand things.
Azure Service Principal and Managed Identity are both identity options in Azure that provide authentication and authorization capabilities. Here's a brief explanation of the differences between them:
- Azure Service Principal:
• Azure Service Principal is an identity created for use by an application or a service.
• It is typically used when you need to grant permissions to an application to access Azure resources.
• Service Principals are commonly used in scenarios where you need non-interactive access, such as automation or deployment scripts.
• Service Principals are created and managed separately from the Azure resources they access.
• They can be assigned roles and permissions to control access to Azure resources.
• Service Principals require a client ID and client secret or a certificate for authentication.
- Managed Identity:
• Managed Identity is a feature of Azure Active Directory (Azure AD) that provides automatic management of the identity lifecycle.
• It eliminates the need to manage credentials manually.
• When you enable a Managed Identity on an Azure resource (e.g., virtual machine, Azure Function), a service principal is created automatically and associated with that resource.
• Managed Identities can be used to authenticate and authorize requests to Azure services, eliminating the need for explicit credentials.
• The lifecycle management, including rotation and renewal of credentials, is handled automatically by Azure AD.
• Managed Identities can be used in scenarios where an application needs to access Azure services securely without managing secrets.
In summary, Service Principals are typically used for non-interactive access and require explicit management, while Managed Identities are automatically managed by Azure AD and provide a more streamlined approach to authentication and authorization for Azure resources.
OAuth 2.0, SAML, and Kerberos are all authentication and authorization protocols used in different contexts and scenarios. Here's a comparison of these protocols:
OAuth 2.0:
Purpose: OAuth 2.0 is primarily designed for delegated authorization, allowing users to grant access to their resources without sharing their credentials directly.
Use cases: OAuth 2.0 is commonly used in scenarios involving third-party applications and APIs, such as social media login, mobile app authentication, and API access.
Token-based: OAuth 2.0 relies on access tokens, which are issued by an authorization server after the user's approval. These tokens are then used by the client to access protected resources.
Authorization: OAuth 2.0 provides a framework for authorization, but it does not define how user identity is verified or authenticated.
Standards: OAuth 2.0 is an industry-standard protocol and has wide support across various platforms and services.
SAML (Security Assertion Markup Language):
Purpose: SAML is an XML-based standard for exchanging authentication and authorization data between an identity provider (IdP) and a service provider (SP).
Use cases: SAML is commonly used in single sign-on (SSO) scenarios, where a user logs in once and gains access to multiple applications or services without re-authentication.
XML-based: SAML messages are based on XML and typically exchanged over HTTP or HTTPS. They contain assertions that provide information about the user's identity and attributes.
Centralized identity management: SAML relies on a centralized identity provider that authenticates the user and generates SAML assertions, which are then consumed by service providers to grant access.
Standards: SAML is an industry-standard protocol widely adopted in enterprise environments, particularly for federated identity management.
Kerberos:
Purpose: Kerberos is a network authentication protocol designed to provide secure authentication over an insecure network. It verifies the identities of clients and servers communicating over an open network.
Use cases: Kerberos is commonly used in enterprise environments, where it provides single sign-on capabilities and secures network communications.
Ticket-based: Kerberos uses tickets to authenticate users and services. A ticket-granting ticket (TGT) is obtained by the client after authentication, which is then used to obtain service tickets for accessing specific services.
Symmetric key cryptography: Kerberos uses symmetric key cryptography to secure the authentication process. It relies on a trusted third-party Key Distribution Center (KDC) that issues and manages the necessary cryptographic keys.
Standards: Kerberos is an industry-standard protocol and is integrated into various operating systems and network services.
In summary, OAuth 2.0 is primarily used for delegated authorization in third-party application scenarios, SAML is commonly used for SSO and federated identity management, and Kerberos provides secure network authentication in enterprise environments. The choice of protocol depends on the specific use case and requirements of the system or application being developed.

Microsoft Azure Active Directory uses various terms to show the status of multi-factor authentication (MFA) for each user. These user states are shown in the Azure portal and all start out as disabled.
Enabled: The user has been enrolled in MFA but has not completed the registration process. They will be prompted to complete the registration process the next time they sign in.
Enforced: The user has been enrolled and has completed the MFA registration process. Users are automatically switched from enabled to enforced when they register for Azure AD MFA.
**Disabled: ** This is the default state for a new user that has not been enrolled in MFA.
Keep in mind, regarding the enforced MFA user status, some older non-browser apps, like Office 2010 or earlier, modern authentication protocols won’t work. In order to enable MFA for user accounts in these apps, with Azure AD multi-factor authentication still enabled, app passwords can be used instead of the user’s regular username and password.
Within Azure security, the terms "Actions," "dataActions," "notActions," and "notDataActions" are related to role-based access control (RBAC) and are used to define the permissions and access rights for various Azure resources. Let's break down each term:
-
Actions[]: This refers to the list of actions or operations that a user or identity is allowed to perform on a specific Azure resource. These actions can include read, write, delete, execute, or other specific operations associated with that resource. For example, if you have an Azure virtual machine, the actions might include starting, stopping, restarting, or resizing the VM.
-
dataActions[]: This is similar to "Actions[]," but it specifically focuses on data-related operations or actions that a user or identity can perform on a particular Azure resource. Data actions are typically associated with data-centric services like Azure Storage, Azure SQL Database, Azure Cosmos DB, or Azure Data Lake Storage. These actions might include read, write, delete, or modify operations on the data stored within those services.
-
notActions[]: The "notActions[]" property is used to explicitly deny certain actions or operations on an Azure resource. It allows you to restrict specific actions that might be allowed by default for a particular role. By specifying "notActions[]", you can define a list of actions that should be denied to the user or identity associated with that role.
-
notDataActions[]: Similar to "notActions[]," "notDataActions[]" is used to explicitly deny specific data-related actions or operations on an Azure resource. It allows you to further restrict the data-related actions that might be allowed by default. By specifying "notDataActions[]", you can define a list of data actions that should be denied to the user or identity associated with that role.
In summary, "Actions[]" and "dataActions[]" define the allowed actions or operations that can be performed, while "notActions[]" and "notDataActions[]" define the denied actions or operations on Azure resources. These properties are used in RBAC to fine-tune access permissions for users, groups, or service principals within Azure.
