Last week Mijingo released a new ebook by Mark Huot: Securing ExpressionEngine 2.
The 30-page “ebooklet” covers how to secure your EE 2 install so your application files and passwords are safe from the public, a streamlined EE installation structure that will make it easier to manage the EE files and site, how to safely use custom queries and how to expertly set up your EE security settings.
The ebooklet is available in PDF and epub formats. Learn more about it from Mijingo: http://mijingo.com/ebooklets/securing-expressionengine-2
