WordPress is one of the most popular content management systems for publishing information online. Over 20% of sites use WordPress so it is a popular target for attacks.
WordPress.tv has some videos on WordPress security to help people improve the security of their sites.
Notice the kid in the front row. You can never start too early to learn about this important topic.
I like the videos which provide concrete steps for improving security. A lot can be done by doing updates to fix small details that are a source for attacks.
