External factors for WordPress Security
The external factors regarding WordPress Security are :
- Your own computer, especially Windows PC should be free from malware and virus. We recommend to use UNIX or UNIX like operating system to access WordPress (S)FTP , run commands through CLI , working on PHPMyAdmin etc. It is not that, using a Mac or Linux PC will make you 100% safe, you must check your computer with an / multiple up to date security softwares.
- Never use weak or easy to guess username and password
- Avoid using Shared Hosting. It is better to use VPS with root access from very well known web hosts like The Rackspace Cloud, Media Template or Amazon. Obviously a managed Hosting is superior.
- Never use Free CDN. Use a paid Content Delivery Network.
- Never use a Theme, Plugin from questionable source. Questionable source includes craked or nulled Themes and Plugins. The reason is, these can have embedded scripts itself enough to breech WordPress Security, additionally the reverse engineering process can itself render it a dangerous plugin.
- It is better to rename the original theme’s name – both of folder and stylesheet. This gives an extra edge for WordPress Security, as hacker will take time to understand the theme’s structure.
- Remove unnecessary HTML comments from your WordPress Source code – again its an extra edge for WordPress Security as Hacker will have less knowledge about the plugins to attack.
- More the uptime of a Server, more enhanced is the WordPress Security. The reason is – if PHP does not run, Apache modules are off – the php files can be opened on browser like plain text files !
- It is obvious that uptime and non-failure of server plays a big role on WordPress Security. Load Balancers with Cloud Hosting enhances WordPress Security.
- Use a reliable backup service for nightly backup.

Via .htaccess enhance WordPress Security
For those who are using Apache server, .htaccess is the most powerful tool to prevent access. Apart from root, all subfolders (wp-admin, wp-content and custom folders) must have own .htaccess. This is an example .htaccess (for root) to enhance Wordpress Security :
# This will prevent browsing of readme file as it gives links
deny from all
# This will prevent editing htacess itself
deny from all
# This is very important for WordPress Security to prevent viewing of install file
deny from all
# This is most important for WordPress Security as wp-config.php will open like a text file if Apache, PHP are not running
deny from all
