1. Don’t use pirated themes and plugins
Sometimes it can be easy to get paid plugins or themes for free, but those pirated plugins and themes come with huge risks. Nothing in this world is for free. Whoever giving you the opportunity to download paid plugin or theme for free from their website, they might provide plugin or theme with backdoor or ads script. These themes and plugins can easily compromise your WordPress website and also steal sensitive information. That’s why you should always download these plugins and themes from reliable sources or directly from the developers’ official website and official WordPress repositories.
2. Keep everything up to date
Staying up to date with the latest version of WordPress and plugins, there is a decent practice to keeping your WordPress website secure. Every update version may contain bugs and security fixes. By staying with an updated version helps to protect against being a target for pre-identified signs that exploit hackers can use to gain access to your site.
3. Use strong passwords
This is the first thing and the mandatory thing you should follow. If you are using a simple password like ‘098765, 123abc, password’, you need to change this password immediately. While this password may be accessible to remember, it’s also extremely easy to guess and break with brute force. That’s why it’s important to use a complex password like a variety of numbers, nonsensical letter combinations, and special characters like % or ^.
4. Keep daily automatic backups
Regular backup is a good practice to reduce damage in case something bad happens. Your website can be hacked anytime, so if you have a backup, you can restore your WordPress website to a working state at any time. To keep backup your website, you can use backup plugins. There are many paid and free backup plugins.
5. Don’t keep “admin” as username
Some one-click tools install a WordPress website with an administrator account with username as “admin”. Usernames make up half of the login credentials that easier for hackers to do brute-force attacks. To reduce the chance of being hacked by cracked administrator password with brute force, change the username from “admin” to something else immediately.
6. Add two-factor authentication
The two-factor authentication technique on the login page is another security part to keep secure your website. This method requires when a user login by using a two-step authentication system. The first step to authenticate requires the username and password, and the second step requires the user to authenticate via a one time generated PIN code sent via SMS or RSA token generated in the authenticator app. This will reduce all login credential related hack risk.
7. Don’t use default database prefix
By default, WordPress makes use of wp_ as a prefix for all tables in your WordPress database. If you do not change the default table prefix of the WordPress database then it makes it easier for hackers to run automated tools to inject your database when the website is vulnerable. By changing the default database table prefix, you may reduce damage even when your website is vulnerable to SQL injection!
8. Disable file editing
WordPress website has a built-in code editor in the dashboard that allows you to edit your theme and plugin files. To access it go to Appearance Editor and Plugins Editor. We recommend to disabled this feature. Because when hackers gain access to your WordPress dashboard, they can inject malicious code.
To disable file editing you need to edit wp-config.php file and add the following line of code:
9. Use SSL certificate
Secure Sockets Layer (SSL) is mandatory for every website to transfer information securely. SSL is a protocol that encrypts all data when transferring from browser to server, making it more difficult to read by a third party. Without an SSL certificate, all of the data between the user’s web browser and web server are delivered in plain text.
10. Use a security plugin
You should use a security plugin to keep your WordPress website secure. Because security plugins take care of basic website security and cover best practices. WordPress security plugins offer file integrity monitoring, remote malware scanning, security activity auditing, blacklist monitoring, effective security hardening, post-hack security actions, security notifications, and even website firewall.
