How to secure MySQL data and achieve PCI compliance

This week I will be the moderator for a MySQL Webinar How to secure MySQL data and achieve PCI compliance being held Thursday, September 11, 2008, 10:00 am PST, 1:00 pm EST, 18:00 GMT.

Recently I wrote about Do you store credit cards in your MySQL Database? . If you do, then PCI Compliance is not something you can ignore.

This webinar will not only be discussing PCI Compliance, but also MySQL data security. Our panel includes Didier Godart from MasterCard Worldwide, one of three members who drafted the Payment Card Industry Data Security Standard 1.0.

For more information on the various PCI Compliance and Encryption options for MySQL , check out the Packet General website.
