Simplify database authentication management with the Amazon Aurora PostgreSQL pg_ad_mapping extension
- Authentication serves as the foundational pillar of security in any enterprise environment, playing a pivotal role in safeguarding sensitive data and resources from unauthorized access.
- This post explores the use of Kerberos authentication for Amazon Aurora PostgreSQL-Compatible Edition using AWS Directory Service for Microsoft Active Directory and particularly the new pg_ad_mapping extension.
- Kerberos authentication offers centralized authentication and single sign-on (SSO) benefits, along with the use of short-lived tickets for enhanced security.
- Aurora PostgreSQL authentication offers password authentication, AWS Identity and Access Management database authentication, and Kerberos authentication. Each method operates independently.
- Kerberos authentication on Amazon RDS and Aurora can be used in conjunction with AWS Managed Microsoft AD.
- Prior to versions 14.10 and 15.5, Amazon Aurora PostgreSQL supported only Kerberos-based authentication with AD for individual users.
- In addition to AD user authentication, AWS provides an enhanced access control mechanism by integrating with AD security groups using the pg_ad_mapping extension.
- The Aurora PostgreSQL pg_ad_mapping extension streamlines access management and mapping of AD security groups to database roles.
- The solution harnesses the capabilities of the pg_ad_mapping extension to empower groups of enterprise users from an AWS Managed Microsoft AD server.
- Security best practices for Aurora PostgreSQL are discussed.
