Description

When SSL enforcement is disabled on Azure MySQL Database Servers, connections to the database are vulnerable to man-in-the-middle attacks and data interception. This security vulnerability allows attackers to potentially capture sensitive data transmitted between client applications and the database server, including credentials, personally identifiable information, and business-critical data. To secure your MySQL server, you must explicitly set ssl_enforcement_enabled to ENABLED, as shown below:

resource "azurerm_mysql_server" "good_example" {
  name                = "good-mysql-server"
  location            = "East US"
  resource_group_name = "example-rg"

  ssl_enforcement_enabled = ["ENABLED"]
}

Compliant Code Examples

resource "azurerm_mysql_server" "good_example" {
  name                = "good-mysql-server"
  location            = "East US"
  resource_group_name = "example-rg"

  ssl_enforcement_enabled = ["ENABLED"] # ✅ Correct setting
}

Non-Compliant Code Examples

resource "azurerm_mysql_server" "bad_example" {
  name                = "bad-mysql-server"
  location            = "East US"
  resource_group_name = "example-rg"

  ssl_enforcement_enabled = ["DISABLED"] # ❌ SSL enforcement is not enabled
}
