The 3 Tier Security Approach
- First is the hosting layer: Must be properly configured (LAMP) and secured by the hoster. If a hoster server is compromized, your website can be compromized.
- Second is the website layer: The website layer sits on top of the hosting layer. If your website is not up to date and configured correctly, (CMS, SSL), then your site can be compromized.
- Third is the security layer: The security layer protects your website from the outside world. If you dont have a wall to block the malware and intrusions, your website will be compromized.
