  • Why to secure the blog ??
    • The hacker can
      • Insert his advertisements in our blog
      • Insert malicious codes in our blog, this may remove our blog from Search engine listings
      • Bring down our site, by deleting all the content !!
  • Keep everything up to date. Keep your WordPress installation and plugins up to date, Whenever there is update make sure you have the latest version. Whenever Wordpress or any software developer releases the update for there software they usually release the notes with the reason of update. Now if its security patch then they also release the vulnerabilities that the older version have in it. (else hide the WordPress version) So It is always good to keep your softwares updated else the hackers can easily misuse the loopholes in the softwares you are using. This also applies to the Operating system and application softwares that you are using in your computer. Keep your anti-virus updated with latest virus definition, because hackers can use your computer to hack your blog.
  • Change the Login ID By Default WordPress uses the Login ID as Admin, Change it. Now hackers have to guess the Login ID and Password both. i.e. Double security. To change the Login ID of Wordpress you can direct fire the SQL queries on your database, or there is one plugin to change the Login ID directly via simple interface. [Plugin URI : http://tr.im/NUd5] Or you can create a new administrator user and delete the original Admin user from your WordPress admin panel.
  • Use strong password Strong password means ?? Use plugin : “Login LockDown” - http://wordpress.org/extend/plugins/login-lockdown/ Login LockDown records the IP address and timestamp of every failed login attempt. If more than a certain number of attempts are detected within a short period of time from the same IP range, then the login function is disabled for all requests from that range. This helps to prevent brute force password discovery.
  • Use SSL for Login Use Encryption technique while login using “Secure Sockets Layer” this can be implemented using a plugin : “ Admin SSL ” http://wordpress.org/extend/plugins/admin-ssl-secure-admin/ Or follow the directions given by Wordpress Codex site to use the SSL in your own way. : http://codex.wordpress.org/Administration_Over_SSL
  • Change the Login URL The default login URL for WordPress is /wp-login/ which is known to everyone, hackers can give try of guessing attack on that URL, so best way is to change the login URL. Plugin called “Stealth Login” will help you do do so. http://wordpress.org/extend/plugins/stealth-login/ This plugin allows you to create custom URLs for logging in, logging out, administration and registering for your WordPress blog. Instead of advertising your login URL on your homepage, you can create a URL of your choice that can be easier to remember than wp-login.php
  • Use robots.txt file Use robots.txt file to restrict the bots access to private files like admin pages, etc People can use Google search tricks to hack into your site. So why allow Google to crawl your private pages ? Use Disallow : /wp-admin/ Disallow: /wp-include/ Disallow: /wp-content/plugins Disallow: /wp-content/themes This will restrict all search engine bots from accessing your those folders.
  • Simple things that you should follow
    • Install popular plugins and from WordPress repository only.
    • Insert empty index.php file in wp-content/plugin/
    • Use anti-comment spam plugins like Akismet.
    • Switch off the new user registration if your site don’t requite new registrations.
