WordPress Protection: 4 Golden Tips to Keep in Mind
So far, WordPress is popular now more than ever. Blogs, mini-websites, and even web portals are powered by a website builder WordPress. However, WP security issues lie behind its convenience and ease of learning. The wide use of WordPress CMS makes it among top targets for cybercriminals.
The most efficient tricks are highlighted in this article. Besides, be sure that you
always maintain your WP website via encrypted VPN connections (here’s the best VPN rating to have at hand).
Protection Against XSS-Injections
What’s the matter?
Programmers tend to protect GET- and POST- queries, however, that doesn’t go far enough. It’s necessary to protect a site against XSS-injections and modification attempts of GLOBALS and _REQUEST variables.
What should a man do?
This problem can be vanished by means of a code. The code blocks the attempts to change GLOBALS and _REQUEST variables as well as XSS-injections. A user is to enter the code into a .htaccess file placed in the root directory.
Here is the code:
That’s how it works:
The code serves to check all queries. In case a query makes attempts to change GLOBALS and _REQUEST variables’ values, the code blocks them and shows a 403 error.
Information Hiding
What’s the matter?
When a user logs in a WordPress site and enters a wrong username or a password, the system informs him/ her about it with a special message. But what if a hacker will be informed as well? Let’s hide this readout.
What should a man do?
To cope with this task, a man is to open a functions.php file located in a theme folder:
wp-content → themes → your theme.
When the file is found, it’s time to enter a code:
Save the changes and presto – notifications are hidden.
That’s how it works:
Thanks to this trick, it’s possible to rewrite a login_errors() function. As a consequence of this, a potential hacker will not see a message about incorrect login details. It’s a good step to make your site safe.
SSL Protocol
What’s the matter?
To make your data-in-motion protected against prying eyes, it’s required to use an SSL protocol. This protocol provides data continuity and confidentiality.
What should a man do?
When your provider allows using SSL, a person is to open a wp-config.php file (you’ll find it in the root directory) and add the line with the code:
That’s how it works:
It’s easy. WordPress relies on many constants and FORCE_SSL_ADMIN is one of them. It is responsible for the compulsory working of SSL protocol when using an admin panel.
Hide WordPress Version
What’s the matter?
Every page of a WordPress website contains information on the version of the CMS. It might become a big problem as when a cracker possesses such information, he /she knows about the vulnerabilities of the WP version. It may bring harm to your site.
What should a man do?
Thus, it’s advisable to hide this data. Open a functions.php file (it has already been described above) and add code:
Also, a man is to delete a readme.html file, as it also contains information on the CMS version. The file is located in the root directory.
That’s how it works:
When a hacker doesn’t know what version of WordPress is used, it’ll be rather problematic to identify possible vulnerabilities and make use of them.
Today everything needs protection whether it is an IoT device or a news portal. Adversaries become too savvy and manage to hack the things like aquariums, coffee machines and whatnot.
However, smart development work on the project, preventive measures, data flow analysis, and observance of safety precautions will help to reduce the risk of your WordPress site to be cracked.
