Defend Your Website: 8 Online Security Threats You Can’t Ignore

how to improve wordpress security

Websites can face several types of threats and create problems for the owners. 


Malware is software that is designed to cause harm to a website or its users. This can include viruses, worms, Trojans, and other malicious programs that can infect your site and compromise security.


Hacking refers to unauthorized access to a website or its data. This can be done by exploiting the website’s code vulnerabilities or using stolen credentials to log in.

DDoS Attacks

DDoS (Distributed Denial of Service) attacks are a type of cyber attack in which multiple computers or devices are used to overwhelm a website with traffic, causing it to become unavailable to users.


Phishing is a social engineering attack in which attackers trick users into divulging sensitive information, such as login credentials or financial data.

Cross-Site Request Forgery (CSRF)

CSRF, or Cross-Site Request Forgery, is a cybersecurity vulnerability where an attacker manipulates a user’s web browser to perform unauthorized actions on a trusted website. By exploiting the user’s trust, the attacker can make fraudulent transactions or access sensitive data. To prevent CSRF attacks, developers use techniques like CSRF tokens and secure coding practices to validate and ensure the integrity of requests.

Brute Force Attacks

Brute force attacks are hacking attacks in which attackers use automated software to try and guess login credentials, usually by repeatedly attempting to log in with different usernames and passwords.

SQL Injection

SQL injection is a type of attack that targets the database behind a website. Attackers can inject malicious code into the database through input fields on the website, allowing them to steal data or take control of the site.

Cross-Site Scripting (XSS) 

Cross-Site Scripting is an attack in which an attacker injects malicious code into a web page that other users view. This can be done by exploiting the website’s code vulnerabilities or tricking users into clicking on a malicious link.

Man-in-the-Middle (MITM) Attacks 

A Man-in-the-Middle attack occurs when an attacker intercepts communication between a website and its users. The attacker can then eavesdrop on the communication or modify it by changing the information sent or stealing user credentials.

9 Updated Security Practices of WordPress 

WordPress Security Best Practices

We created this list by combining some old security practices with new ones that will help you to boost your website defense significantly. 

a) Keep Your WordPress Software and Plugins Up To Date

Regularly updating your WordPress software and plugins is one of the easiest and most effective ways to improve your website’s security. Updates often include security patches that address known vulnerabilities and weaknesses in the software.

Moreover, promptly installing updates significantly reduces the risk of attackers exploiting known vulnerabilities to gain unauthorized access to your website or compromise sensitive data. 

Some updates often introduce new features and performance enhancements, enhancing your website’s functionality and user experience.

Keep in mind that there is a slight possibility of compatibility issues or unexpected problems arising. Creating a backup of your website before installing any updates is wise to mitigate such risks. 

b)Use Strong, Unique Passwords

Using strong, unique passwords can help prevent brute-force attacks and unauthorized access to your website. Consider using a password manager to generate and store strong passwords for your WordPress site and other online accounts.

Regarding passwords, strength and uniqueness are key factors in preventing unauthorized access to your WordPress site. Weak passwords can be easily guessed or cracked, leaving your site vulnerable to brute-force attacks.

On the other hand, reusing passwords across multiple sites can amplify the impact of a security breach if one of those sites is compromised.

c) Have Two-Factor Authentication for Logins 

Two-factor authentication adds an extra layer of security to your WordPress login process, requiring a second form of verification in addition to your password. This can include a text message, an authentication app, or a physical security key.

You can enable 2FA using a plugin like Google Authenticator, Authy, or Duo Two-Factor Authentication. Install the plugin from the WordPress plugin repository, enable the by linking your WordPress account to a 2FA application on your mobile device or generating backup codes.

Finally, when you or another user attempts to log in to your WordPress site, you’ll be prompted to provide a second verification form. This typically involves entering a time-sensitive, one-time code generated by the 2FA application installed on your mobile device.

d) Limit Login Attempts

Limiting the number of failed login attempts can help prevent brute-force attacks. You can use plugins or modify your WordPress site’s code to limit the number of login attempts allowed. 

Plugins Wordfence Security, Limit Login Attempts Reloaded, and Login LockDown can help you enable this function on your WordPress site. 

e) Use HTTPS Encryption

HTTPS encryptions can help protect your website and user data from interception by malicious actors. You can use a free SSL certificate or purchase one from a trusted certificate authority to enable HTTPS encryption on your WordPress site.

You will need an SSL certificate to get HTTP Encryption for your website. You can either get a paid SSL certificate or a free SSL certificate. Paid certificates are usually obtained from trusted certificate authorities, while free certificates are available from not-so-trustworthy groups. It would be best for you to select a perfect SEO service and invest some on SSL certificate. 

After managing an SSL certificate, generate a CSR from your web hosting control panel or server software. The CSR contains your website’s information and is used to verify your ownership during the certificate issuance process.

f) Get a Web Application Firewall (WAF)

A WAF can help detect and block malicious traffic before it reaches your website. Consider using a reputable WAF service or installing a WAF plugin on your WordPress site. Getting a WAF service is pretty easy. 

#1 Choose a WAF Solution 

Research and select a WAF solution that fits your requirements. Some popular WAF providers include Cloudflare, Sucuri, and Akamai.

#2 Sign up for the WAF Service 

Create an account with your chosen WAF provider and choose a suitable plan or subscription that aligns with your needs.

#3 Configure DNS Settings

Follow the instructions provided by the WAF provider to configure your DNS settings. This typically involves pointing your website’s DNS records to the WAF service. You may need to update your domain’s DNS records at your domain registrar or within your web hosting control panel.

#4 Set up Website Routing

Configure your WAF service to route incoming traffic to your website. This ensures all traffic passes through the WAF’s security checks before reaching your server.

#5 Customize WAF Rules and Settings

Depending on the WAF service, you can customize rules and settings according to your website’s specific needs. This may involve selecting predefined security rulesets, setting up custom rules, or adjusting security levels.

#6 Test and Monitor

After enabling the WAF, thoroughly test your website to ensure proper functionality. Keep a close eye on the WAF’s logs and monitoring tools provided by the service to identify and address any false positives or potential security threats.

#7 Regularly Update and Review Settings

Stay informed about emerging threats and best practices for WAF configurations. Regularly review and update your WAF settings to ensure optimal security coverage.

It’s important to note that the specific steps may vary depending on the WAF provider and the service you choose. DEPENDING ON YOUR WEBSITE’S ARCHITECTURE AND SETUP, some WAF solutions may require additional configuration or integration steps.

g) Use a Secure Hosting Service 

Choosing a reputable and secure web hosting provider is important to WordPress security. Look for a provider that offers security features such as regular backups, firewall protection, and malware scanning.

h) Utilize Security Headers

Security headers are HTTP response headers that provide additional security to your website. When a user visits a website, these headers are sent from the server to the client’s browser as part of the HTTP response.

There are many popular security headers that you can use.

#1 X-Content-Type-Options

Header: X-Content-Type-Options: nosniff

Purpose: Instructs the browser to prevent content type sniffing, ensuring that the content type provided by the server is strictly followed. This helps prevent MIME-based attacks and protects against certain types of XSS attacks.

#2 X-XSS-Protection

Header: X-XSS-Protection: 1; mode=block

Purpose: Enables the built-in XSS protection feature of modern browsers. It detects and blocks potential cross-site scripting attacks, protecting your website and users from malicious scripts.

#3 Content-Security-Policy

Header: Content-Security-Policy: default-src ‘self’; script-src ‘self’ cdn.example.com; style-src ‘self’ ‘unsafe-inline’;

Purpose: Defines a content security policy restricting the allowed sources of scripts, stylesheets, and other resources. In this example, scripts can only be loaded from the same origin or from the CDN at cdn.example.com, while inline stylesheets are allowed but limited to the same origin.

i) Monitor Your Website’s Activity

Regularly monitoring your website’s activity can help you promptly detect and respond to security threats. Consider using security plugins or services to provide real-time alerts and monitor your website’s activity.
