Protecting MySQL passwords with sha256_password plugin

Over the years, MySQL has used three different mechanisms for securing passwords both for storage and for transmission across networks.  This blog post aims to provide a brief history of the various mechanisms and highlight reasons to migrate accounts to use the sha256_password mechanism introduced in MySQL Server 5.6.

Emulating roles with expanded proxy user support in 5.7.7

MySQL Connect HOL content posted

Just a quick post to note that the content from my hands-on lab at MySQL Connect (“MySQL Enterprise Features in Practice”) has been uploaded to the content catalog, and can be found here.  This includes the 36-page lab manual and example commands and programs (mostly in Java; the package includes both compiled and source code).  For those who attended the lab, this is an opportunity to complete the exercises we didn’t get to in the 2.5 hours, and for those who missed it, an opportunity to learn more about the features and capabilities of key MySQL Enterprise products and features such as MySQL Enterprise Audit plugin, MySQL Enterprise Monitor and MySQL Enterprise Security (PAM plugin).  I hope to expand on the lab content to demonstrate other features such as MySQL Enterprise Backup,  MySQL Enterprise High Availability and MySQL Enterprise Scalability, and will post updates via my blog.
