2 2  
3 -
4 -This document outlines the process of **encrypting SQL Server databases** using **Transparent Data Encryption (TDE)** and backing them up to **Azure Storage**. TDE ensures data at rest is encrypted, leveraging a **Master Key (MK)**, **TDE Certificate**, and **Database Encryption Key (DEK)** for encryption.
5 -
6 -The process also includes creating a **credential** for secure backup to **Azure Blob Storage**, providing a scalable and secure solution for storing encrypted databases in the cloud.

11 -
12 -**~1. Create a Master Key in the master Database**
13 -The first step is to create a **Master Key** in the master database. This key will be used to encrypt other cryptographic objects, such as certificates and symmetric keys, within SQL Server.
14 -
15 -
16 -**2. Create a TDE Certificate (Encrypted by the Master Key)**
17 -Next, generate a **TDE certificate** that will be used to encrypt the **Database Encryption Key (DEK)**. This certificate is encrypted by the **Master Key** created in step 1, providing an additional layer of security.
18 -
19 -
20 -**3. Choose the Database to Create the Database Encryption Key (DEK)**
21 -For the selected database, create the **Database Encryption Key (DEK)**. The DEK will be encrypted by the **TDE certificate** and will use the **AES-256 encryption algorithm** to ensure data is securely encrypted at rest.
22 -
23 -
24 -**4. Enable Encryption for the Database**
25 -Once the **DEK** has been created, enable **TDE** for the database. This ensures that all data written to the database is automatically encrypted at rest, providing full protection for sensitive information.
26 -
27 -
28 -**5. Create a Credential with a SAS Token**
29 -Finally, create a **credential** that allows SQL Server to access Azure Blob Storage. This credential is created using a **Shared Access Signature (SAS) token**, which ensures secure and authenticated access to the storage account for backup purposes.

53 -=== ===
54 -
55 -=== Conclusion: Backup to Azure Storage Account with TDE Encrypted Databases ===
56 -
57 -The attempt to back up an **encrypted database** (with Transparent Data Encryption - TDE) from **SQL Server Management Studio (SSMS)** to an Azure Storage Account was unsuccessful. This issue arises because **Azure does not permit TDE-encrypted databases to be backed up directly to Azure Storage using SSMS**.
58 -
59 -However, after decrypting the database, we were able to successfully back it up to the Azure Storage Account via SSMS. This confirms that **backups can be performed on an unencrypted database**, but **not on an encrypted database**.
60 -
61 -

65 -= **2. Enabling Transparent Data Encryption (TDE) Using Azure Key Vault** =
66 -
67 -
68 -**Introduction:** This document outlines the process of enabling **Transparent Data Encryption (TDE)** on an **Azure SQL Managed Instance (SQL MI)** using a **Customer-Managed Key (CMK)** stored in **Azure Key Vault**. The encryption is managed using an asymmetric key from **Azure Key Vault**, ensuring that all data within the SQL Managed Instance is encrypted using a strong encryption algorithm.
69 -
70 -
71 -===== **1. Generate a Key in Azure Key Vault** =====
72 -
73 -
74 -**- Navigate to Azure Key Vault:**
75 -
76 -* Go to the **Azure Portal** and select **Key Vault** (DemoRudiTest).
77 -
78 -**- Generate a New Key:**
79 -
80 -* Go to the **Keys** section and click **Generate** to create a new key.
81 -
82 -**- Configure Key Settings:**
83 -
84 -* **Name the Key**: Choose a name for your key, e.g., mysqlmikey.
85 -* **Key Type**: Select **RSA** as the key type.
86 -* **RSA Key Size**: Choose an **RSA key size** of **2048-bit**. (optional)
87 -
88 - Note:
89 -
90 -* switching from 2048-bit RSA to 4096-bit RSA for TDE will affect performance, but the actual impact might be minor, especially on modern hardware and typical workloads.
91 -* **It will likely affect CPU usage** more than disk I/O, and the impact might be more noticeable during key management operations (key generation, encryption, etc.).
92 -* If your database is not under heavy load and your hardware can handle the extra processing, the trade-off for better security may be worth it.
93 -
94 -**- Create the Key:**
95 -
96 -* Click **Create** to generate the key.
97 -
98 -
99 -===== **2. Enable TDE on the SQL Managed Instance** =====
100 -
101 -===== =====
102 -
103 -**- Navigate to Your Managed Instance:**
104 -
105 -* Go to your **SQL Managed Instance** (sqlmi-ebs-lab).
106 -
107 -**- Enable Transparent Data Encryption (TDE):**
108 -
109 -* Under **Security**, select **Transparent Data Encryption**.
110 -
111 -**- Configure TDE with a Customer-Managed Key (CMK):**
112 -
113 -* Select **Customer-managed key** as the encryption type.
114 -* Choose the key you created earlier from **Azure Key Vault** (mysqlmikey).
115 -
116 -**- Set the Key as Default TDE Protector:**
117 -
118 -* Make the key the **default TDE protector** for your instance.
119 -
120 -**- Save Configuration:**
121 -
122 -* Click **Save** to apply the changes.
123 -
124 -=== **Conclusion** ===
125 -
126 -After following these steps, **TDE** has been successfully enabled on your **SQL Managed Instance** using an **asymmetric key** stored in **Azure Key Vault**. All databases within the instance are now encrypted using the same encryption key (identified by the same encryption thumbprint). You can now securely back up these encrypted databases from **SSMS** to **Azure Storage**.
127 -
128 -This process ensures that your data is protected both at rest and during backup, offering enhanced security for your managed databases in the cloud.

132 -=== **1. Backup Specific Databases Using SQL Server Agent Jobs** ===
133 -
134 -This document describes the process of creating an automated **SQL Server Agent Job** to back up only the **DBA databases** in a SQL Server instance. The backups will occur **daily at 3:00 AM** and will be stored in an **Azure Storage Account** for secure and reliable cloud storage.
