MySQL encryption performance, revisited
+1 Vote Up -0Vote Down

This is part two on a two-part series on the performance implications of in-flight data encryption with MySQL. In the first part, I focused specifically on the impact of using MySQL’s built-in SSL support with some rather surprising results. Certainly it was expected that query throughput would be lower with SSL than without, but I was rather surprised by the magnitude of the performance hit incurred at connection setup time. These results naturally lended themselves to some further investigation; in particular, I wanted to compare …

Send to Kindle

Audit MySQL isn’t an easy task by default, you can use some technics like tcpdump, write a parser for general log, use MySQL proxy, or you can use some of audit plugins available out there(Mcafee MySQL Audit Plugin or MySQL Enterprise Audit Log Plugin for example).

The installation is easy and require just a few steps, I’m using MySQL 5.5 32 bits, so …

Creating custom rules in MySQL Enterprise Monitor
Employee +3 Vote Up -0Vote Down

Quite some time ago, I published scripts to implement password policies for MySQL, and promised to show how to expose violations of that policy via MySQL Enterprise Monitor (MEM).  That stalled somewhat with other objectives, but I want to revisit it now that MEM 3.0 is GA.  If you haven’t tried MEM 3.0 yet, consider doing so – it’s …

Introducing audit_login: simple MySQL login logfile based auditing
+2 Vote Up -0Vote Down

audit_login is a simple MySQL login auditing plugin, logging any login or login attempt to log file in JSON format.

It seems that audit plugins are all the rage lately... We've developed out simple plugin a month ago as part of our database securing efforts; by auditing any login or login attempt we could either intercept or later investigate suspicious logins.

However we quickly realized there is much more to be gathered by this info. …
