Amazon RDS for PostgreSQL now supports configurable cipher suites

[Amazon Relational Database Service (RDS)](https://aws.amazon.com/rds/postgresql/) for PostgreSQL now supports modifying the ssl\_ciphers parameter. SSL Ciphers (or cipher suites) are combinations of algorithms used to secure network connections between a client and server. They handle key exchange, authentication, encryption, and message integrity verification to ensure secure and confidential communication. Amazon RDS for PostgreSQL 16.1 and later will support modification of the ssl\_ciphers parameter. You can select cipher suites from the Amazon RDS for PostgreSQL [allow list](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/PostgreSQL.Concepts.General.SSL.html#PostgreSQL.Concepts.General.SSL.Ciphers) to align with your organization's security standards and maintain consistent security configurations across database deployments. Amazon RDS for PostgreSQL makes it simple to set up, operate, and scale PostgreSQL deployments in the cloud. See [Amazon RDS for PostgreSQL Pricing](https://aws.amazon.com/rds/postgresql/pricing/) for pricing details and regional availability. Create or update a fully managed Amazon RDS database in the [Amazon RDS Management Console](https://console.aws.amazon.com/rds/home).
