How to Keep Your WordPress Site Secure
Protect Your WordPress Admin Interface
Your WordPress admin panel is a goldmine for criminals. Therefore, you need to restrict access to it as much as possible: only those who need to access it should be able to. In any case, you should restrict everybody’s ability to make changes to your header.php file.
As we’ve seen with this recent redirect attack, hackers with admin credentials to your site can directly and easily make changes to your theme’s header.php file. You can effortlessly disable a user’s ability to edit PHP files in your admin interface by adjusting your wp-config.php file. Simply copy and paste the following code in your wp-config.php file:
# Disable Theme Editing define( 'DISALLOW_FILE_EDIT', true );
Other tips for keeping your admin interface secure:
- Use strong passwords
- Change all passwords periodically
- Limit the number of login attempts
- Check to make sure that no fake admin accounts have been created
- Do not use “admin” as your admin username
- Enable two-factor authentication
Update WordPress, Themes and Plugins to Latest Versions
It is critical to update WordPress and all of your themes and plugins to their latest versions. In addition to improved functionality, most updates are provided to address security concerns and vulnerabilities, so update to the latest versions as soon as they are available.
Make Sure Your Computer(s) Is Free of Viruses and Malware
Any precautionary measures you take to protect your site from malware would all be null and void if your computer contains any viruses or malware. That’s because a hacker could access your site’s login details from your computer and swiftly proceed to infect the site. Therefore, it’s important to install a good antivirus program on all computers you use to log into your WordPress site.
Most of us love WordPress for its flexibility, among many other reasons. Indeed, it is the most popular open-source Content Management System (CMS) out there. However, the reasons we love it so much are the very reasons that make it vulnerable to cyber-attacks. It’s important to be aware of that and take the necessary steps to protect your site.
