In the last couple of years, there has been a tremendous rise in the number of Internet users and bloggers.
Wordpress has become one of the most popular and widely used application for blogger as it is easy to setup and configure. Since the popularity of wordpress is growing, now hackers are trying to hack or inject wordpress based websites which causes many problems for the bloggers to maintain their blogs and such events cause unnecessary downtime, loss of visitors, affects Search Engine Optimization etc.
Following is the list of some of the security features and tips which can be used to secure the wordpress based blogs:-
1. Securing wp-config.php
wp-config.php file contains the database information like database name, database username, password. By default
wp-config.php has 644 permission which means a normal user can easily read your
wp-config.php. So, set the permissions of the file to 750 which will disable other users from reading it.
2. Vulnerabilities in the WordPress
Vulnerabilities of Wordpress could be defined as a program or script that allows an attacker to bypass normal wordpress settings. To avoid such problems, keep your blog updated to latest versions. Older version of Wordpress contains old functions and scripts which can be easily hacked.
Also keep all of your plugins and themes updated and if you are not using any specific plug-in, delete it from the system.
3. Hiding WordPress version
If you are running a wordpress version which has known vulnerabilities, then its not a good option to keep your wordpress version open to public. There are many plugins which hide the wordpress version from public OR you can simply add
<?php remove_action('wp_head', 'wp_generator'.; ?> in
function.php of your theme.
4. Renaming the administrative account
By default the Wordpress sets administrator username as "
admin" for the Blog.For better security it's not suggested to use "admin". After installation you can create a new user with administrator rights and delete "admin".
5. Protect WP-* Folders
Block
wp-* folders from being crawled and indexed by search engines. This can be done by blocking access to wp-* from robot.txt. Add following line in your robot.txt
6. Firewall Plugins
There are a few plugins that scans suspicious requests based on rule databases and/or white-lists.

PHPIDS", a generic security layer for PHP applications, while
