6.2 Ensure Azure Database for PostgreSQL uses only Microsoft Entra Authentication (Manual)

Profile Applicability

  • Level 1

Description

Ensuring that Microsoft Entra Authentication is the only authentication method prevents the local PostgreSQL authentication from being used.

Rationale

The use of a centralized Identity and Access Management (IAM) solution such as Microsoft Entra ID is highly recommended for all activity related to Identity, Authentication, Authorization, and Accountability.

Decentralized IAM -- such as local authentication methods -- may present additional vulnerability and introduce avoidable administrative complexity.

Impact

None documented.

Audit Procedure

Audit from Azure Portal

  1. From Azure Database for PostgreSQL select a server to audit.
  2. Under the Security section, click Authentication.
  3. In the main window, under the Authentication header, ensure that "Authentication method:" reflects the selection of Microsoft Entra authentication only.

Expected Result

The "Authentication method" should be set to Microsoft Entra authentication only.

Remediation

Remediate from Azure Portal

  1. From Azure Database for PostgreSQL select a server to remediate.
  2. Under the Security section, click Authentication.
  3. In the main window, under the Authentication header where "Authentication method:" provides three options, select Microsoft Entra authentication only.

Default Value

By default, Azure Database for PostgreSQL uses PostgreSQL authentication only.
