Securing and Rotating WordPress Database Credentials with AWS Secrets Manager

AWS Secrets Manager is a simple and powerful way to handle secrets (such as database username/password credentials). It provides support for storing, retrieving, managing, and rotating credentials at an affordable cost (currently $0.40 per secret per month). However, it’s not terribly easy to use with WordPress. I have not been able to find any documentation … Continue reading Securing and Rotating WordPress Database Credentials with AWS Secrets Manager →

AWS Secrets Manager Rotation in CloudFormation

I found AWS’s documentation for how to setup Secrets Manager secret rotation in CloudFormation to be severely lacking as no AWS documentation explains how to use the secret rotation templates provided by AWS within CloudFormation. Automating Secret Creation in AWS CloudFormation gives an example of how to setup the CloudFormation resources for the secret and … Continue reading AWS Secrets Manager Rotation in CloudFormation →

Using Dynamic References to AWS Systems Manager Parameter Store Secure Strings with Elastic Beanstalk

Dynamic references in CloudFormation to secure strings are very handy, providing a simple way to keep secrets (such as passwords) secure. However, SSM Secure String Parameters are only supported in a limited set of places and Elastic Beanstalk environment variables are not one of them (feature request for adding support). Therefore, if you want to … Continue reading Using Dynamic References to AWS Systems Manager Parameter Store Secure Strings with Elastic Beanstalk →

HTTP/3 Support Added to cURL in Gentoo

HTTP/3 may still be in the draft state but that isn’t stopping software from adding support for it. As a Gentoo developer, I decided to maintain Gentoo’s reputation for not being one to shy away from the bleeding edge by adding (optional) support for HTTP/3 to cURL. I believe that this makes Gentoo the first … Continue reading HTTP/3 Support Added to cURL in Gentoo →

Trusting AWS RDS Certificates in Docker and Beanstalk

To connect to AWS RDS databases using TLS/SSL, the client must trust the certificate provided by RDS; RDS doesn’t use certificates trusted by the CAs (Certificate Authorities) included by operating systems. Without TLS/SSL, the connection to the database isn’t secure, meaning an attacker on the network between the client (running in EC2) and the database … Continue reading Trusting AWS RDS Certificates in Docker and Beanstalk →

End to End Encryption with Beanstalk

Beanstalk is often configured to terminate SSL at the load balancer then make the connection to the web server/application instances using unencrypted HTTP. That’s usually okay as the AWS network is designed to keep such traffic private, but under certain conditions, such as those requiring PCI compliance, DoD/government rules, or simply out of an abundance … Continue reading End to End Encryption with Beanstalk →

This approach provides significant advantages such as automatic horizontal scaling, seamless failover, and no need for session affinity. By using JDBC, the database the application … Continue reading Change the Spring Session JDBC Serialization Method to Improve Performance →

Performance Testing WebDAV Clients

Part of migrating applications from on-premises hosting to cloud hosting (AWS, Azure, etc) involves re-evaluating how users access their data. A recent migration involved users running Windows 10 accessing a Windows file share using the SMB protocol. Since SMB isn’t safe to run directly over the Internet (it’s usually not encrypted and it has a … Continue reading Performance Testing WebDAV Clients →
