Steps for Databases (25) requiring certificate update to "rds-ca-rsa2048-g1"

0

Hi re:Post, We have a set of PostgreSQL instances that require their certificates to be updated. In looking at the update via the console process, it seems pretty straight forward but I wanted to contact re:Post and double-check/verify. Enter image description here Enter image description here q1) We need to / is recommended that we switch from using "rds-ca-2019" to "rds-ca-rsa2048-g1".
[ ] Is "rds-ca-rsa2048-g1" recommended for the Ohio region / us-east-2? In selecting the "Schedule Update" we see the following screen which recommends "rds-ca-rsa2048-g1" and that the db does not require a restart. Enter image description here q2) So if we click "Schedule" and the update for the certificate runs during the scheduled maintenance window on June 30th, is there anything else we need to do in order to have our CA SSL accept new connections via the update to "rds-ca-rsa2048-g1" ?
Or are we done? Thank you for your time and help! Best Regards, Donald

Hello,

Yes, Before applying the new certificate to your DB instances, update the trust store of any clients and applications that use SSL/TLS and the server certificate for connections.

To check if the application using SSL connection, please check this documentation https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/ssl-certificate-rotation-postgresql.html#ssl-certificate-rotation-postgresql.determining-server

You can download the TLS/SSL certificates from the following link: https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/UsingWithRDS.SSL.html#UsingWithRDS.SSL.CertificatesAllRegions

  • Hi Sivaraman, thank you for your quick reply and help. Regarding, "update the trust store of any clients and applications that use SSL/TLS and the server certificate for connections." beside the RDS instances, we have our application running on hundreds of apple I-phones. How would we get the downloaded "global-bundle.pem" to those devices? Thank you for your time and help! Best Regards, Donald

  • Are you sure your iPhones have DIRECT access to the database? That would be very unsual for an application. Plus rds-ca-2019 is unlikely to be on your iphones anyway..

  • Right, of course Gary. Yeah the iPhones would not direct access to the dbs. I'm new to the dev shop in my company and glad I asked here vs in a meeting! Thanks! Donald
