6.10 Ensure server parameter 'require_secure_transport' is set to 'ON' for PostgreSQL server (Automated)

Profile Applicability

  • Level 1

Description

Enable require_secure_transport on PostgreSQL flexible servers.

Rationale

SSL connectivity helps to provide a new layer of security by connecting database server to client applications using Secure Sockets Layer (SSL). Enforcing SSL connections between database server and client applications helps protect against "man in the middle" attacks by encrypting the data stream between the server and application.

Impact

None documented.

Audit Procedure

Audit from Azure Portal

  1. Login to Azure Portal using https://portal.azure.com.
  2. Go to Azure Database for PostgreSQL servers.
  3. For each server, under Settings, click Server parameters.
  4. In the filter bar, type require_secure_transport.
  5. Ensure that the VALUE for require_secure_transport is set to ON.

Audit from Azure CLI

Ensure the below command returns a value of on:

az postgres flexible-server parameter show --resource-group <resourceGroup> --server-name <serverName> --name require_secure_transport

Audit from PowerShell

Ensure the below command returns a Value of on:

Get-AzPostgreSqlFlexibleServerConfiguration -ResourceGroupName <resourceGroup> -ServerName <serverName> -Name require_secure_transport

Audit from Azure Policy

Policy ID: c29c38cb-74a7-4505-9a06-e588ab86620a Name: 'Enforce SSL connection should be enabled for PostgreSQL flexible servers'

Expected Result

The require_secure_transport server parameter should be set to ON.

Remediation

Remediate from Azure Portal

  1. Login to Azure Portal using https://portal.azure.com.
  2. Go to Azure Database for PostgreSQL servers.
  3. For each server, under Settings, click Server parameters.
  4. In the filter bar, type require_secure_transport.
  5. Set VALUE for require_secure_transport to ON.
  6. Click Save.

Remediate from Azure CLI

Use the below command to enable require_secure_transport:

az postgres flexible-server parameter set --resource-group <resourceGroup> --server-name <serverName> --name require_secure_transport --value on

Remediate from PowerShell

Update-AzPostgreSqlFlexibleServerConfiguration -ResourceGroupName <resourceGroup> -ServerName <serverName> -Name require_secure_transport -Value on

Default Value

By default, secure connectivity is enforced, but some application frameworks may not enable it during deployment.
