Why You Must Secure WordPress

Before you disavow WordPress forever, there are a few things you need to consider. First, WordPress is the most popular CMS, powering 810 million websites. In other words, over 43.6% of ALL websites use WordPress, which makes it a big target for hackers.

Second, WordPress is an easy target for hackers because of weak passwords, plugins, and other vulnerabilities. These vulnerabilities are because many website owners don’t know how to protect their websites. Most of them don’t even think about securing their WordPress websites.

If you are one of them, you are in danger. Not only do you risk a security breach, but restoring your WordPress website after it gets hacked can be a time-consuming and expensive process.

In addition, the consequences of getting hacked are far from pleasant. A breached website may experience significant data, assets, and credibility losses. Furthermore, if your website manages customer information, the incident can jeopardize their personal data and billing information.

It’s predicted that by 2025, the cost of cybercrime damages will reach up to $10.5 trillion annually. It is said that 80% of reported cyber crimes are generally attributed to phishing attacks. At 16%, phishing was the second most common reason for data breaches and the costliest, averaging $4.91 million in breach costs.

Surely, you don’t want to be part of that statistic. So, let’s help you do better and protect your online presence from the bad guys out there. This post will go over WordPress security and share nineteen ways to protect your WordPress site from hackers, comment spammers, and malware.

These WordPress security tips are for people who have never had a website before and more experienced website owners and WordPress users. In addition, we’ve noted the skill level required to execute each tip.

But first, let’s examine common WordPress security threats and vulnerabilities and how they affect your WordPress website.

Understanding WordPress Security Threats

While managing your WordPress website, you must grasp that security threats are constantly evolving. According to recent data, over 4.7 million WordPress sites face hacking attempts annually. You should stay informed about the latest security measures to protect your digital assets better.

Impact on Website Performance

The consequences of security breaches can severely affect your website’s performance. When your site faces security issues, you might experience slower loading times, unexpected downtime, and compromised user data. These problems can lead to lost revenue and damaged reputation.

Another critical aspect is how security measures influence your site’s functionality. While implementing robust security protocols, you need to balance protection with performance. Excessive security measures can increase server load by up to 15%, potentially affecting your site’s speed and user experience.

What Are Common WordPress Security Vulnerabilities?

For your WordPress site, the most significant vulnerabilities include outdated plugins, weak passwords, and SQL injections. According to recent statistics, 53.3% of all new vulnerabilities are XSS attacks, while broken access control accounts for 12.9% of security issues. Your site’s security depends on understanding and addressing these common entry points for attackers.

Based on the WPScan Vulnerability Database, here are some of the most common types of WordPress security vulnerabilities:

• Cross-site request forgery (CSRF) – forces the user to execute unwanted actions in a trusted web application.
• A distributed denial-of-service (DDoS) attack incapacitates online services by flooding them with unwanted connections, rendering a site inaccessible.
• Authentication bypass – allows hackers to access your website’s resources without verifying their authenticity.
• SQL injection (SQLi) – forces the system to execute malicious SQL queries and manipulate data within the database.
• Cross-site scripting (XSS) – injects malicious code that turns the site into a transporter of malware.
• Local file inclusion (LFI) – forces the site into processing malicious files placed on the server.

What Is A “Hack?”

A “hacked” website has been compromised by an unauthorized user (a hacker) in some way. WordPress sites can be hacked in many different ways. Still, the most common type of compromise is when an unauthorized user gains access to your WordPress control panel and installs malware or spammy links on your pages.

When this happens, removing these bad things from your website is almost impossible unless you have experience with WordPress development.

What Is Comment Spam?

Comment spam is an unsolicited message sent to WordPress websites. Spammers often comment on WordPress blogs and articles linking back to their websites. They hope to drive traffic, earn money from pay-per-click ads, or build cheap link popularity.

Comment spam is dangerous because it can clog up your website’s comment threads, making it difficult for people to have genuine discussions on your blog. Clicking on a spammy link by accident can also lead to malware infections.

Perhaps more worrisome, comment spam can lower your website’s authority ranking. As a result, search engines like Google will demote blog posts containing spammy comments.

What Is Malware?

• Malware (short for malicious software) refers to any malware you don’t want on your computer, such as viruses, key-loggers, trojan horses, and the list goes on and on. WordPress sites can get infected by malware almost exactly like a personal computer, usually through an unpatched security vulnerability.
• Viruses are a form of malware that can spread to other WordPress sites, much like how the flu virus spreads from one person to another.
• Key-loggers are malware that records the keys you press on your keyboard, allowing someone to steal your usernames and passwords.
• Trojan horses are a type of malware that disguises itself as something else (usually a useful program) to trick you into installing them on your computer.

How To Know If Your WordPress Website Is Infected With Malware

If you’re unsure whether your WordPress website has been infected with malware, there are a few telltale signs to look for. One of the most common is if your site is suddenly slow or unresponsive. A sluggish website could be caused by malware using all your server’s resources, preventing your pages from loading correctly.

Curious? You can check your website for malware using a variety of free tools. Just enter your web address (domain name), and you’ll receive a report.

Another sign of infection is if you see strange ads or links on your website that you didn’t put there yourself. Finally, if you receive emails from WordPress about failed login attempts but haven’t tried logging in, someone else is likely trying to hack into your site.

If you believe your WordPress website may be infected with malware or have any other WordPress security questions or concerns, we are here to help!

Essential WordPress Security Measures

Implementing a comprehensive security strategy is not optional if you want to protect your WordPress website effectively. With over 4.7 million WordPress sites getting hacked annually, your website needs multiple layers of protection working together to create a robust security shield.

After implementing basic WordPress security measures, server-level protection becomes your next defense line. Your hosting environment is vital in maintaining website security through firewall configurations, malware scanning, and access control protocols.

How to Secure WordPress Login

Despite WordPress’s robust security features, your login page remains a primary target for attackers. Statistics show that over 30,000 WordPress sites face brute-force attacks daily. You must implement multiple security layers to protect your login page from unauthorized access attempts and potential breaches.

Password Best Practices

Secure passwords form your first line of defense against unauthorized access. You should use passwords that are at least 12 characters long, combining uppercase and lowercase letters, numbers, and special characters. Your password should be unique for each account and changed every 90 days. Avoid using common words or personal information that could be easily guessed.

Two-Factor Authentication Setup

With two-factor authentication, you add an extra security layer to your login process. Studies show that 2FA can prevent 99.9% of automated attacks. You can choose from various authentication methods, including SMS codes, authenticator apps, or biometric verification.

Understanding the implementation process is vital for optimal security. When you enable 2FA, you’ll receive a unique code on your chosen device after entering your password. This additional step ensures that attackers can’t access your site without the second authentication factor, even if your password is compromised. You can set up 2FA for all user roles or limit it to administrator accounts for enhanced security.

Plugin and Theme Security Tips

Managing your WordPress plugins and themes requires careful attention to security details. You must implement robust security measures to protect your website from potential vulnerabilities and malicious attacks.

19 WordPress Security Tips You Should Follow Immediately:

Tip #1: Select Your Hosting Partner Carefully (Beginner Skill)

Security starts with choosing a reliable hosting provider that offers advanced protection features. You should look for providers offering regular server monitoring, automated backups, and DDoS protection. Your hosting environment should include real-time threat detection and isolated hosting environments to prevent cross-site contamination.

The Internet is full of cheap and “affordable” hosting providers. These providers are hell-bent on offering you some of the most amazing hosting plans in the market. But before you choose one, pause and think it over for a moment.

Your website hosting is the most crucial part of your website. But can you seriously risk your website security to save a few bucks? Instead, you should carefully evaluate different WordPress hosting options and select a trusted WordPress hosting service provider.

Tip #2: Eliminate the “Admin” Username (Beginner Skill)

WordPress sets the default username as admin, and many website owners never bother to change it. As a result, admin is the first username hackers will try when they launch an attack against your site. If that name is present, they only need to guess the password.

As such, you should never use that particular username for your WordPress website.

Tip #3: Use Strong Passwords (Beginner Skill)

The most common reason for compromised WordPress website security is hacked passwords. So, it’s critical to create strong and complex passwords and alter them at regular intervals. Creating strong passwords means using a combination of letters, numbers, and symbols that are hard to guess.

Some of your most critical security measures should focus on access management. You must implement strong password policies, enable two-factor authentication (2FA), and carefully manage user roles. According to recent studies, 41% of WordPress users don’t use 2FA, leaving their sites vulnerable to unauthorized access.

WordPress has a built-in way to help generate secure passwords, so make sure you take advantage of it! People often avoid strong passwords as they are difficult to remember. But this is a mistake. Instead, try using some of the best Password Managers to do the job.

When you set your passwords, don’t stop at the WordPress admin area; repeat the process for your WordPress hosting accounts, email addresses, and FTP accounts.

Tip# 4: Set Minimal User Permissions (Beginner Skill)

However, it’s not just about your passwords but those of other people on your site. First, ensure everyone only has permission to do what they need to minimize their risk. It makes sense to get familiar with WordPress user roles to understand what they do and what each user role is allowed to do.

For example, you don’t want to give a one-time guest blogger admin access. A Contributor role is likely much more appropriate. To be on the safe side, you may want to set your default user role to Subscriber (under Settings > General > New User Default Role).

Tip #5: Install WordPress Security Plugins (Beginner Skill)

WordPress websites are highly vulnerable to malware attacks. If you do not keep a manual watch on the source code of your website, you might not even know that your code is infected.

Unfortunately, you need to know coding to determine this. But there is a better and easier option. WordPress security plugins are specifically designed to identify and eliminate malicious codes and malware from your website.

The best part is that they work around the clock, and you won’t have to do anything. Some of the best examples of WordPress security plugins are Succuri and Wordfence.

Tip #6: Avoid Nulled Themes (Beginner Skill)

Nulled WordPress themes are unauthorized versions of the original premium themes. Usually, they are sold at a lower price to attract users. However, they typically have many security flaws.

Often, nulled theme providers are hackers who hacked the original premium theme and inserted malicious code, including malware and spam links. Moreover, these themes can be backdoors to other exploits that endanger your WordPress site.

Using nulled themes is both morally unethical & illegal. Furthermore, since nulled themes are distributed illegally, their users cannot receive any support from the developers. This lack of support means that if they cause any issues to the site, you’ll have to figure out how to fix them and secure your WordPress site by yourself.

To avoid this, we recommend picking a WordPress theme from its official repository or trusted developers. To purchase a premium theme, look for options in official theme marketplaces such as ThemeForest.

Tip# 7: Remove Unused Themes and Plugins (Beginner Skill)

Keeping unused plugins and themes on the site can be potentially harmful, especially if the plugins and themes haven’t been updated. Outdated plugins and themes can increase the risk of cyberattacks as hackers can use them to access your site.

To delete unused themes, open your WordPress admin dashboard and navigate to Appearance -> Themes. Next, click on the theme you want to delete, and a pop-up window will appear showing the theme details. Next, click the Delete button in the bottom-right corner.

Tip #8: Perform Regular Security Scans (Intermediate Skill)

Usually, malware and malicious code can go unnoticed for a long time unless you regularly scan your website. Scanning your site can ensure you stay safe and always protect your website.

Most new WordPress website owners neglect to install a security scanner immediately. Unfortunately, this means that malware or a malicious code injection can go unnoticed.

The best time to scan your website for malicious code and malware is now. Unfortunately, many users won’t notice anything wrong with their website until it is too late. Even if your site is not hacked or affected, you should still learn to scan your WordPress site for malicious code. It will help you protect your website against future attacks.

Tip #9: Keep WordPress And Plugins Up To Date (Intermediate Skill)

Some of the most common security breaches occur through outdated software. Regularly update your WordPress core, themes, and plugins to patch known vulnerabilities. In 2023, 53.3% of all new vulnerabilities in the WordPress ecosystem were related to outdated components. With automated update systems, you can ensure your website stays current with the latest security patches.

While choosing plugins and themes, you should prioritize reputable developers and official marketplaces. Your selection process must include checking reviews, update frequency, and compatibility with your WordPress version. According to recent studies, 52% of WordPress vulnerabilities come from poorly vetted third-party components.

There’s no compromise when it comes to maintaining your plugins and themes. You must keep all components updated to their latest versions, as outdated software accounts for 86% of successful WordPress attacks. Regular security patches help protect your site from known vulnerabilities.

You should conduct monthly audits of your plugins and themes. Your audit process should include removing inactive plugins, verifying the necessity of active ones, and checking for any security warnings or reported vulnerabilities. Automated security scanning tools can help you identify potential threats before they become problems.

• Verify plugin authenticity
• Monitor security updates
• Remove unused plugins
• Check compatibility regularly

Tip #10: Use Two-Factor Authentication (Intermediate Skill)

Two-factor authentication adds an extra layer of security to your WordPress website. When you log in, not only will WordPress ask for your password, but they’ll also require something else before logging in.

For example, after typing in your username and password, you must enter a code sent to your phone via SMS or email. Setting up two-factor authentication on WordPress sites is straightforward today, so don’t hesitate!

Tip #11: Back Up Your WordPress Site Regularly (Intermediate Skill)

Last but not least, back up your WordPress site regularly! Making regular backups is the most important tip on this list. When disaster strikes your WordPress site, restoring if you have a backup is straightforward.

Setting up regular backup schedules and implementing malware scanning routines will help you maintain a secure environment and quickly recover from any potential security incidents.

The easiest way is to back up your database and files separately. Then, in the event of a malicious attack on your site, you only need to restore one or the other, depending on what went wrong. Several WordPress backup plugins will automatically back up your site at regular intervals.

Tip #12: Limit Login Attempts (Intermediate Skill)

WordPress allows its users to make unlimited login attempts on the site. However, this is a perfect opportunity for hackers to brute force their way using various password combinations until they find the right one.

That’s why limiting failed login attempts is essential to prevent such attacks on the website. Limiting failed attempts can also help monitor suspicious activities on your site.

Most users only need a single try or a few failed attempts, so you should be suspicious of any questionable IP addresses that reach the attempt limit.

A plugin is one way to limit login attempts and increase WordPress security.

Tip# 13: Use the Latest Version of PHP (Advanced Skill)

PHP is what WordPress runs on. It’s present on the server of every website built with the CMS. Just like WordPress, the programming language is constantly under development. New versions come with performance enhancements and vulnerability fixes.

You must run the latest version for that alone. In addition, each new PHP version receives support and updates for only two years. The currently supported versions are 8.1 (support ends December 2025), 8.2, 8.3, and 8.4, so we recommend using one. Unfortunately, only a little more than half of WordPress sites follow that advice.

Tip #14: Change the Default WordPress Database Prefix (Advanced Skill)

The database holds and stores all crucial information required for your site to function. For this reason, hackers often target databases with SQL injection attacks. This technique injects malicious code into the database and can bypass WordPress security measures and retrieve the database content.

SQL injections comprise 80% of cyber-attacks executed on WordPress websites, making it one of the biggest threats. Hackers execute this attack because many users forget to change the default database prefix wp_. Fortunately, most WordPress security plugins allow you to change your database prefix without coding skills.

Tip #15: Enable the Lockdown Feature (Advanced Skill)

Enabling URL lockdown protects your login page from being accessed by unauthorized IP addresses and brute force attacks. You need a web application firewall (WAF) service such as Cloudflare or Sucuri to do that.

Using Cloudflare, you can configure a zone lockdown rule. This rule specifies the URLs you want to lock down and the IP range allowed to access them. Anyone outside the specified IP range cannot access them.

Sucuri has a similar feature called URL path blocklist. Essentially, you add the login page URL to the blocklist so no one can access it, and then you allow authorized IP addresses to access the login page.

Tip #16: Disable XML-RPC (Advanced Skill)

XML-RPC is a WordPress feature that allows users to access and publish content via mobile devices, enable trackbacks and pingbacks, and use the Jetpack plugin on their WordPress website.

However, XML-RPC has some weaknesses that hackers can exploit. One feature lets them make multiple login attempts without being detected by security software, making your site prone to brute-force attacks.

Hackers can also use the XML-RPC pingback function to perform DDoS attacks. It allows attackers to simultaneously send pingbacks to thousands of websites, crashing the targeted sites.

To determine whether XML-RPC is enabled, run your site through the XML-RPC validation service and see whether you receive an error or a success message. If you get a success message, the XML-RPC function is running.

Tip #17: Secure Your Wp-Config File (Advanced Skill)

The wp-config.php file contains essential information about your WordPress site, including your database name, username, and password. By default, this file is located in the root folder of your WordPress installation. However, you can move it to a different location and protect it with a .htaccess file. Moving this file makes it harder for hackers to access it. You should consider it if you’re running a WordPress site.

Tip #18: Use SSL/HTTPS (Advanced Skill)

SSL (Secure Socket Layer) or TLS (Transport Layer Security) is a protocol that helps secure web server and browser communications. When enabled, it will encrypt all data sent between the two parties so that no one can eavesdrop on the conversation.

With SSL certificates, you can encrypt data transmission between your server and visitors’ browsers. You must ensure your website uses HTTPS protocol to protect sensitive information, including login credentials and payment details. This security measure is crucial for e-commerce sites handling customer data.

Certificate validation shows visitors that your site is trustworthy and secure. Modern SSL certificates provide up to 256-bit encryption and can handle multiple domains under a single certificate. Your SSL implementation should include proper redirect rules and regular certificate renewal to maintain continuous protection.

Tip #19: Use A Firewall (Advanced Skill)

A firewall helps protect your WordPress site from unwanted traffic and attacks. It acts as a shield between your website and the Internet, blocking any malicious packets before they can reach your server. There are many different firewalls available, both free and paid. If you’re running a WordPress site, I recommend using one!

Securing Your WordPress Site from Hackers

Every WordPress security attack is different. Hackers can access your sites using various ways like password guessing, inserting malicious codes into your files, brute force attacks, etc. You must always be ready for any attack to secure your WordPress sites from hackers or intruders. You never know who is going to hack or crack your website files.

Taking backups, keeping your websites safe from malicious codes, and installing essential security tools can save you a lot of time, money, and effort. However, NEVER take your WordPress security lightly, as prevention is always better than the cure.

Be sure to implement the WordPress security tips mentioned in this guide to harden the security of your WordPress sites. We are here to help!

Backup and Recovery Strategies

You should maintain multiple backup copies stored in different locations, including cloud storage and local drives. According to recent statistics, 40% of WordPress sites that experience data loss without proper backups never fully recover their content.

Automated Backup Solutions

Even with manual backups, automated solutions provide superior protection by ensuring regular, scheduled backups of your entire WordPress installation. You can configure these tools to perform daily, weekly, or monthly backups of your database, files, and media content. Your backup solution should include real-time monitoring and instant notifications if any backup process fails.

Recovery Process Guidelines

If your WordPress site experiences issues, having a well-documented recovery process is vital. You should maintain a clear checklist that includes steps for identifying the problem, selecting the appropriate backup version, and implementing the restoration process. Your recovery plan should ensure minimal downtime during the restoration process.

For instance, you should regularly test your backup restoration process by performing mock recoveries in a staging environment. This practice helps you identify potential issues before an actual emergency occurs. Consider maintaining separate backups for your database and files, as this approach offers more flexibility during recovery and can reduce restoration time by up to 60%.

Summing up

With WordPress powering over 43% of all websites globally, it remains a prime target for cybercriminals. A single breach can have devastating consequences for your business, underscoring the necessity of a robust security strategy for 2025. Adopting a comprehensive and proactive approach, implementing multiple layers of protection—from basic password security to advanced firewall solutions—is essential.
