WordPress now powers over 40% of all websites. It’s the platform of choice for small business owners, freelancers and organisations of all sizes.
But with great popularity comes significant vulnerability.
Cyber threats are constantly evolving, and ignoring website security is not an option – it’s an open invitation to hackers.
One of the main prevention methods is to install security plugins that do malware scanning and firewall protection.
By the end of this guide, you’ll have the practical knowledge to harden and secure your WordPress site.
This includes understanding the basic security risks, implementing advanced security like two-factor authentication (2FA), monitoring website logs and not disclosing too much information in error messages to keep your online presence safe.
Let’s secure your WordPress site.
Why WordPress Security?
Whether you’re selling products, sharing content or providing services, your website is at risk.
A security breach can damage your reputation, lose sensitive data, disrupt your business and even cost you thousands of dollars.
In today’s digital world where cyber threats are more advanced than ever, knowing the common vulnerabilities is key to keeping your website secure.
Some of the common security issues include:
Data breaches
Data breaches are where hackers gain unauthorised access to steal sensitive data such as customer information, payment details or intellectual property.
This can lead to loss of trust from your audience, lawsuits and compliance breaches.
Malware injections
Malware injections are where malicious code is injected into your website’s code.
This can compromise your website’s functionality, harm the user experience, expose visitors to malware and negatively impact your search engine rankings.
Google may even blacklist your site.
Brute force attacks
Brute force attacks are where hackers try to guess weak or default passwords to get into your admin page.
Once in, they can take control of your site, damage it or use it as a launch pad to attack users.
Unauthorised access
A single vulnerability – whether it’s outdated software, weak login credentials or no encryption – can compromise your entire website.
The consequences go beyond a temporary downtime, and can impact your business’s bottom line and long term reputation.
Taking proactive measures like keeping your software up to date, using strong passwords and investing in security tools is crucial to protect your site from threats.
WordPress Security
What is WordPress Security?
WordPress security means the strategies, practices and tools used to protect WordPress websites from brute force attacks, malware, malware injections, unauthorised access to admin accounts.
These threats can compromise your website’s data, functionality and user trust.
While WordPress is a secure platform with regular updates to fix vulnerabilities, the real risks are how users configure and manage their WordPress sites.
Weak passwords, outdated plugins or themes and poorly managed hosting environment can be the entry points for attackers.
Strong security measures are crucial to keep your site safe and running.
Common Security Vulnerabilities
1. Outdated Plugins
It’s simple but not doing so is one of the biggest risk to your site’s security.
Hackers target outdated versions of WordPress software and use them as entry points to get unauthorised access.
56% of WordPress vulnerabilities are plugin related.
These vulnerabilities can allow hackers to steal sensitive data, inject malware or even take control of your entire site.
Updates not only fix bugs and improve functionality but also patch security holes, making your site less attackable.
Being proactive with updates is key to protecting your online presence.
2. Weak Login Credentials
Using same or weak passwords too many times is a big vulnerability, giving hackers easy access to your site.
Weak admin passwords are the most vulnerable part of a WordPress site. These passwords are easy to guess or have been already compromised in previous data breaches and your site is exposed.
Add to that brute force attacks where hackers use automated tools to try millions of password combinations and the risk is higher.
Disabling XML-RPC can also help mitigate brute force attacks by limiting access to certain WordPress features.
Without strong, unique passwords and extra security measures your site is an open target to cybercriminals.
3. Code Exploitation
Cross-site scripting (XSS), file inclusion exploits and SQL injections are common vulnerabilities that cybercriminals exploit to compromise systems.
XSS allows hackers to inject malicious scripts into trusted sites and trick users to reveal sensitive information.
File inclusion exploits can allow attackers to execute unauthorised files or access restricted areas of the system.
SQL injections target databases by injecting malicious queries which can lead to data theft, corruption or even giving the attacker admin access.
These threats show why security measures are crucial to protect applications and user data.
Your Responsibility as a Website Owner
Being proactive is key to security.
It’s not a one time effort but an ongoing process that requires regular monitoring, updating and optimising to stay ahead of threats.
Think of your WordPress site’s security as locking all doors and windows in your digital house—except in this case you also need to check for weak spots, fix damages and upgrade your locks as new threats emerge.
By being vigilant and treating security as part of your website maintenance you can protect your data, your users and your online reputation.
SSL is necessary to encrypt data between user’s browser and your web server to secure your site and sensitive information.
Best Practices to Secure Your WordPress Site
Secure Login
1. Strong, Unique Passwords
Your password should be long and complex, mix of uppercase and lowercase letters, numbers and special characters to increase security.
Don’t use easily guessed information like birthdates or common words.
A password manager can help you generate and store strong, unique passwords for all your accounts so you don’t have to remember them.
Strong password habits is a simple but important step to protect your online data.
2. Enable Two-Factor Authentication (2FA)
Adding an extra layer of security with two-factor authentication (2FA) is a must for your admin account.
Even if someone gets your password, they still need a second code—usually sent to your phone or email or generated by an authentication app—to get in.
This extra step reduces the risk of unauthorised access and protect your sensitive data from attacks.
For extra sensitive data protection consider a physical security key like a Yubikey.
3. Limit Login Attempts
Prevent brute force attacks on your site by limiting the number of failed login attempts.
This simple but effective way to stop attackers from guessing passwords.
Security plugins like Wordfence makes it easy to implement this feature and block suspicious activity and improve your site’s overall security.
This can reduce the risk of unauthorised access to your site.
4. Change the Default Admin Username
When you set up a WordPress site using predictable usernames like “admin” or your name it makes it easier for hackers to target your admin account.
Hackers try common usernames when trying to get unauthorised access to sites.
To be more secure you need to choose a unique username that is harder to guess and reduce the risk of brute force attacks and keep your site safe.
Avoid these common and easily guessed usernames:
admin
administrator
root
user
test
manager
admin1
support
webmaster
default
These usernames are targeted in brute force attacks because they are common or part of default configurations.
To secure your site choose a unique and unpredictable username that’s not part of default settings or generic terms.
Pair this with strong passwords and two-factor authentication for extra security.
Update and Maintenance
Update your WordPress core, themes and plugins regularly.
This way you get access to the latest features and improved functionality and also secure your site from security vulnerabilities.
Outdated software can leave your site open to threats so updating is important for performance and security.
Update plugins where possible to ensure you’re running the latest version with the newest features and security fixes.
But be cautious about plugin quality—read the update notes and feedback before updating as not all updates are trouble free.
Use only plugins from trusted developers.
Back up your WordPress site using reliable plugins like UpdraftPlus or Snapshot Pro.
These plugins allow you to schedule backups and store them safely.
This way if your site gets hacked or has technical issues you can restore it to a previous version without losing important data.
Back up your site’s database and files
Back up your site’s database and core files is important to ensure your data is safe in case of security breach or technical issue. In this case backups is your first line of defence against WordPress attacks. Here’s how:

There are many backup plugins for WordPress like UpdraftPlus or Snapshot Pro. These plugins can automate the backup process and ensure your data is safe. They have features like scheduled backups, cloud storage integration and easy restore options making them a good choice to secure your site.
Use FTP or SFTP
For those who prefer a more hands-on approach, using FTP or SFTP to download your site’s files and database is an option. This way you have more control over the backup process and can manually select which files and databases to backup. While it requires a bit more technical knowledge, it ensures you have a full site backup stored safely. Save full site backups to a remote location not just your hosting account.
Use your hosting provider’s backup tool
Many hosting providers have built-in backup tools that can backup your site’s database and files. These tools are user friendly and integrated in your hosting control panel so it’s easy to schedule and manage backups. Check with your hosting provider if they have this service and use it to add another layer of security to your site.
Store Your Backups Safely
Once you have your backups, it’s important to store them safely. Use a WordPress management tool to set automated backups at desired intervals. Most tools and hosting providers will let you schedule and automate backups. Hiring a WordPress maintenance service can monitor website security and backups. This way your data is safe and can be restored quickly in case of security breach or technical issue.

Disable Directory Indexing
Don’t let hackers browse your site’s directories by disabling directory indexing in your htaccess file.
Directory indexing allows visitors to see a list of files in a directory if there’s no index file present, which can expose sensitive information or vulnerabilities.
By disabling it you add another layer of security to your site making it harder for attackers to exploit your system.
It’s a simple but effective security measure every site owner should do.
Disable File Editing in WordPress
Hackers target the wp-config.php file because it contains sensitive information about your WordPress site like database credentials and security keys.
To protect this file from unauthorised access or edit, you can disable file editing in WordPress by adding specific code in the wp-config.php file.
This is also known as “disable file editing wordpress” and prevents administrators from editing theme and plugin files directly from the admin area.
This simple step adds another layer of security to your site.
Secure Sensitive Files
- Restrict access to critical files like wp-config.php and .htaccess, these files control your WordPress settings and site functionality. wp-config.php contains important configuration data, .htaccess manages server settings and can help with security like URL redirection or access control. Protecting these files is crucial to prevent unauthorised changes or security breaches.
- Disable PHP file execution in directories where not needed, like the uploads folder. This adds another layer of security by preventing malicious scripts from being executed in these areas which are often targeted by attackers.
- Never let your root directory be accessible to unauthorised users, this can expose sensitive files and system information. Implement proper permissions and security measures to protect your root directory from threats.
Secure Your Server
Securing your server is key to prevent security breaches and protect your site’s data. Here’s how:
Use a Secure Protocol
Use a secure protocol like HTTPS to encrypt data between your site and visitor’s browser.
An SSL is required for this, it will encrypt all data exchanged.
This will not only protect sensitive information but also boost your site’s credibility and search engine rankings.
SSL is issued by certificate authorities and prices can range from free to hundreds of dollars a year. Many hosting companies offer free SSL for WordPress sites.
Even if your hosting company doesn’t install it, check for Let’s Encrypt.
Let’s Encrypt provides free SSL to website owners, supported by major companies.
Keep Your Server Software Up to Date
Keep your server software up to date to have the latest security patches and features.
Outdated software has vulnerabilities that hackers can exploit so keeping up to date is part of your site’s security.
Use a Web Application Firewall (WAF)
A Web Application Firewall (WAF) is a protective barrier between your site and incoming traffic, filtering and blocking malicious requests before they hit your site.
It protects against threats like SQL injection, cross-site scripting (XSS) and other attacks.
By analysing traffic in real-time a WAF ensures only legitimate users can access your site while keeping malicious actors out.
Services like Cloudflare makes it easy to set up a WAF, offers robust security features to keep your site safe and running smooth.
Monitor Your Server Logs
