4 -1 Create master key in master database (set master key)
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 5  
6 -2 Create TDE certificate (encrypted by MK)
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.
7 7  
8 -3 Backup the Certificate and private key, By encryption with a password ( did not do it in this case due to storage blog problems)
9 9  
10 -4 Choose DB to create the DEK ,Create database encryption key (DEK) with algorithm ( AES= 256) and encryption by certificate

18 -Go--
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.
19 19  
20 ---7 Perform the database backup with the provided parameters
21 -EXECUTE dba.dbo.DatabaseBackup
22 - @Databases = 'dba',                          -- Replace with your database name
23 - @URL = '[[https:~~/~~/zagpebslab.blob.core.windows.net/sql-backups'>>https://zagpebslab.blob.core.windows.net/sql-backups']], -- Azure Blob Storage URL
24 - @BackupType = 'Full',                        -- Full backup
25 - @CopyOnly = 'Y', -- Copy-only backup to avoid breaking backup chain
26 - @Compress = 'Y',                             -- Compress the backup
27 - @Verify = 'N'; -- No verification of backup
28 -GO--
29 29  
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.
30 30  
31 -The backup was unable to be done from smss to azure ( the MI does not support encrypted DBs to be backed up from smss to azure)
32 32  
33 -We have unencrypted a database and backed it up from ssms to azure blob successfully
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.
34 34  
35 35  
36 -Conclusion: Can be done with and unencrypted DB but not with an Encrypted one>
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.
37 37  
38 38  
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.

55 +=== Conclusion: Backup to Azure Storage Account with TDE Encrypted Databases ===
45 45  
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**.
46 46  
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**.

65 += **2. Enabling Transparent Data Encryption (TDE) Using Azure Key Vault** =
52 52  
53 53  
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.
54 54  
55 55  
71 +===== **1. Generate a Key in Azure Key Vault** =====
56 56  
57 57  
74 +**- Navigate to Azure Key Vault:**
58 58  
76 +* Go to the **Azure Portal** and select **Key Vault** (DemoRudiTest).
59 59  
78 +**- Generate a New Key:**
60 60  
80 +* Go to the **Keys** section and click **Generate** to create a new key.
61 61  
82 +**- Configure Key Settings:**
62 62  
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)
63 63  
64 -1 CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'YourStrongPasswordHere!';
65 -GO
88 + Note:
66 66  
67 -CREATE CERTIFICATE TDE_Certificate
68 -WITH SUBJECT = 'TDE Certificate';
69 -GO
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.
70 70  
71 -2 USE master;
72 -GO
94 +**- Create the Key:**
73 73  
74 -SELECT
75 - cert.name AS Certificate_Name,
76 - cert.subject AS Certificate_Subject,
77 - cert.issuer_name AS Issuer_Name,
78 - cert.pvt_key_encryption_type AS Private_Key_Encryption_Type
79 -FROM
80 - sys.certificates cert
81 -WHERE
82 - cert.name LIKE 'TDE%';
96 +* Click **Create** to generate the key.

92 92  
102 +**- Navigate to Your Managed Instance:**
93 93  
94 -USE Normal;
95 -GO
104 +* Go to your **SQL Managed Instance** (sqlmi-ebs-lab).
96 96  
97 --- 6. Create a Database Encryption Key (DEK) and encrypt it with the TDE certificate
98 -CREATE DATABASE ENCRYPTION KEY
99 -WITH ALGORITHM = AES_256
100 -ENCRYPTION BY SERVER CERTIFICATE TDE_Certificate;
101 -GO--
106 +**- Enable Transparent Data Encryption (TDE):**
102 102  
103 -USE [dba]
104 -GO
108 +* Under **Security**, select **Transparent Data Encryption**.
105 105  
106 -CREATE DATABASE ENCRYPTION KEY
107 -WITH ALGORITHM = AES_256
108 -ENCRYPTION BY SERVER CERTIFICATE TDE_Certificate;
109 -GO
110 +**- Configure TDE with a Customer-Managed Key (CMK):**
110 110  
112 +* Select **Customer-managed key** as the encryption type.
113 +* Choose the key you created earlier from **Azure Key Vault** (mysqlmikey).
111 111  
112 -USE [dba1]
113 -GO
115 +**- Set the Key as Default TDE Protector:**
114 114  
115 -CREATE DATABASE ENCRYPTION KEY
116 -WITH ALGORITHM = AES_256
117 -ENCRYPTION BY SERVER CERTIFICATE TDE_Certificate;
118 -GO
117 +* Make the key the **default TDE protector** for your instance.
119 119  
119 +**- Save Configuration:**
120 120  
121 -USE [dba2]
122 -GO
121 +* Click **Save** to apply the changes.
123 123  
124 -CREATE DATABASE ENCRYPTION KEY
125 -WITH ALGORITHM = AES_256
126 -ENCRYPTION BY SERVER CERTIFICATE TDE_Certificate;
127 -GO
123 +=== **Conclusion** ===
128 128  
125 +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**.
129 129  
130 -USE [dba3]
131 -GO
127 +This process ensures that your data is protected both at rest and during backup, offering enhanced security for your managed databases in the cloud.
