General Web Security Resources
Our shared servers employ an extensive set of security modules to protect accounts from server-level (and, to a certain extent, known application-level) threats, including, but not limited to, CageFS via CloudLinux, ModSecurity, OSSEC, CSF (ConfigServer Security & Firewall), and several virus scanning modules.
The possibility of any account-level compromise having come from an attack that was preventable at the server-level is extremely low. While many customers who have experienced an account-level compromise question how this could have happened on our servers, the reality of the situation is that an overwhelming majority of compromises stem from outdated or otherwise insecure software in the customer's account.
We put a lot of effort into balancing the security of the servers with enough flexibility to allow customers to install a wide variety of software. Accordingly, it is the responsibility of the customer to maintain the security of the web applications within their account.
In addition to seeking out additional resources from experienced software developers, we highly recommend the following general tips:
- Use secure connections whenever possible, such as connecting to a site with SFTP rather than FTP, or using a secure 'https' link for any login forms that transmit password data.
- Take regular backups and store them off-server (not in the hosting account).
- Never store old, unused content in your hosting account, including things like abandoned development installations and zipped files.
- Be familiar with the documentation for your software, and how to find information on its functionality.
- Always apply software security updates to core software and any modules, themes, plugins, etc. as soon as possible after they're released.
- Keep up to date with information regarding current security best practices for the software you're using. Subscribing to the mailing list for the software or regularly reading web security blogs are a couple ways to stay informed about new developments.
