We have been having some issues come up recently with clients not fully understanding or knowing exactly how to secure their WordPress site from being hacked. Here's a quick tutorial on how to do exactly that. Credits go to David from Hostwinds for writing this! Step 1 Create a backup of your site. If you have cPanel you can do this with the backup manager. If not I would recommend "backup buddy", a WordPress plugin you can find with a google search. Step 2 Update WordPress Version This is critical because WordPress issues updates that close security vulnerabilities; it's things like this that could keep your site healthy! Step 3 Change Your Login/Password The default WP username is "admin" and hackers know this. So you should change it to something more personal EG "RocketRanger416" or "James86". Best thing to do is to add that new user and make it a admin the delete the original login of "admin" I would suggest really strong passwords (These should incluse UPPER and lowercase letters, numbers, and symbols) Like "Rocket!2@" or "jessieNOMAD12#4" Most hackers try to brute-force your passwords so if it is really strong you should be fine in that regard. Step 4 Change your Wordpress Keys! Many people overlook this step but it is an important one as these keys work as salts for cookies and ensure better encryption of data. Use the Wordpress Key Generator to generate mentioned keys. Now edit your wp-config.php file and fine the lines that look like: and replace them with the ones from the Key Generator. Save and you're good to go. Step 5 Install WP Security Scan This plugin is great and makes securing your site simple. It scans for security vulnerabilities and informs you of any malicious code. If the plugin shows your text as green you should be good. However, if they are not green you will have to fix the problem to make them green. Step 6 Change Table Prefix -- Warning! Make a backup of your database before continuing. -- The default prefix for a WP bsite is "wp_" This makes it so sql injection hacks are easy for the hacker because it is easy to guess. A good prefix would be "march26_" or "magnol1a_" this is a highly recommended change and you can do this with the WP Security Scan Plug-in. WP Security Scan has a tab called "Database". Once you open that tab you have the option to rename your entire prefix to something secure. Step 7 Prevent WordPress hacks by blocking search engine spiders from indexing the admin area. Spiders crawl all over your site structure unless they are told not to, and we don't want that. The easiest way to prevent spiders from indexing the admin area is to create a robots.txt file in your public_html folder with the following lines of code. # User-agent: * Disallow: /cgi-bin Disallow: /wp-admin Disallow: /wp-includes Disallow: /wp-content/plugins/ Disallow: /wp-content/cache/ Disallow: /wp-content/themes/ Disallow: */trackback/ Disallow: */feed/ Disallow: /*/feed/rss/$ Disallow: /category/* Step 8 Prevent .htaccess Hacks .htaccess (hypertext access) is the default name of directory-level configuration file that provides decentralized management of configuration while inside your web tree. .htaccess files are often used for security restrictions on a particular directory. So let's secure your .htaccess! First we want to protect the .htaccess file itself so add the following (Do this for all .htaccess files you have in root and or create) # STRONG HTACCESS PROTECTION order allow,deny deny from all satisfy all Public_html .htaccess below Now lets secure your config.php by adding: # protect wp-config.php Order deny,allow Deny from all Now lets prevent the hacker from browsing your directory tree by adding # disable directory browsing Options All -Indexes Lets prevent some script injections now: # protect from sql injection Options +FollowSymLinks RewriteEngine On RewriteCond %{QUERY_STRING} (\<|%3C).*script.*(\>|%3E) [NC,OR] RewriteCond %{QUERY_STRING} GLOBALS(=|\[|\%[0-9A-Z]{0,2}) [OR] RewriteCond %{QUERY_STRING} _REQUEST(=|\[|\%[0-9A-Z]{0,2}) RewriteRule ^(.*)$ index.php [F,L] Go to your /wp-content folder. Lets limit access to the wp-content directory by creating a .htaccess in the wp-content folder and adding: Order deny,allow Deny from all Allow from all Go to your /wp-admin/ folder. Now if you have a static IP I would recommend creating a .htaccess in your wp-admin folder with the following (replace x's with your STATIC IP) # deny access to wp admin order deny,allow allow from xx.xx.xx.xx deny from all Replace the X's with your IP. Step 9 Last but not least! You can install Wordpress Firewall 2 - this actually prevents most hacking attempts. Use with care, however, because you can lock yourself out of your site! Hope this helps anyone having WordPress security issues, or people who DON'T want to have them.
Really well written. These would be the exact same steps I would suggest. Something thats always good to do not just for wordpress blogs but any site is to talk with your hosting provider. Make sure their kernal versions are up to date and the same with what ever software they use (FTP, SSH, WHMCS, etc). Alot of the time if people really want to hack your site/blog they will attack the server if attacks direclty against your website are unsuccessful.
Have to say thank you so much for this. I recently started my own blog on Wordpress and thought if I installed only a couple of plugins like Askimet and a SEO plugin I would be fine. Some of the things like changing the Wordpress keys wouldn't even have occurred to me.
thx for your infos. im done with the most of this job but I have a question about the keys in wp-config. I use the plugin Infinitewp to manage all my blogs from one point. Therefor I have to enter my ftp data in wp-config.php (otherwise I cant install plugins) Can someone read this if my .htaccess is configured correct?
install Better Wp Security plugin Remove the meta "Generator" tag Change the urls for WordPress dashboard including login, admin, and more Completely turn off the ability to login for a given time period (away mode) Remove theme, plugin, and core update notifications from users who do not have permission to update them Remove Windows Live Write header information Remove RSD header information Rename "admin" account Change the ID on the user with ID 1 Change the WordPress database table prefix Change wp-content path Removes login error messages Display a random version number to non administrative users anywhere version is used
I am not using wordpress due to security purpose. Blogger is better than wordpress, only few people knows this. Again global attack on wordpress in last 7 days.
Good advice! Thank you for the useful information. But remember to set the CHMOD settings correctly (most ignore that). Also these settings do not secure your website from corrupt plugins, they can easily be exploited.
