This article provides various tips on how to improve your website security for performance improvements. Many people often neglect the subject, assuming that their website is small and not worth the effort. However, regardless of the size of your website, attackers will still try to exploit it. As a result, it is essential to adopt these security measures to safeguard your website and protect both your business and customers.

Many malicious activities can cause a website's performance to deteriorate. A site that has been hacked or infected by malware can slow down or even crash, negatively affecting the user experience. Customers are less likely to visit a website that is slow or crashing frequently. Moreover, search engines prioritize user experience, and a lagging website can negatively affect your search rankings, reducing your online presence.

In this article, we will cover various security measures that can enhance the performance of your website, boost your website's search rankings, and protect it from malicious activities. By adopting these measures, you can also increase your users' trust, contributing to repeat visits and more online conversions.

We will start with firewalls and how to implement them on your website to protect your website against malicious users. We will then delve into setting up SSL certificates, strong passwords, user access controls, integrations of CAPTCHA and phishing protections, conducting security audits, vulnerability scans, and more.

Implementing Website Firewalls

A firewall is a crucial security component of any website. A website firewall filters incoming and outgoing traffic and blocks unauthorized access to your site. Firewalls can be categorized into two types: a network firewall and a web application firewall (WAF).

Network Firewall

A network firewall enforces security policies at the network level. It examines traffic packets traveling between different machines or networks and blocks threats based on predefined rulesets. Network firewalls can be hardware or software-based and are usually deployed at the website's perimeter.

Web Application Firewall

A web application firewall (WAF) focuses on protecting the web application itself. It filters traffic based on the content of HTTP requests and responses and blocks attacks like SQL injection, cross-site scripting (XSS), and other application layer attacks. WAFs are software-based and can be deployed on the website server or as a cloud-based solution.

Benefits of a Website Firewall

Implementing a website firewall provides the following benefits:

  • Enhanced security: A firewall blocks malicious traffic before it reaches the server. This reduces the risk of cyber attacks and data breaches.
  • Streamlined compliance: A firewall provides an additional layer of security, which can be useful for regulatory compliance. Many regulations, such as the PCI DSS, require implementing a firewall for web applications.
  • Reduced server load: By blocking malicious traffic before it reaches the server, a firewall reduces the server load. This improves website performance and reduces hosting costs.

How to Implement a Website Firewall

There are several ways to deploy a website firewall:

  • Hardware firewall: A hardware firewall is a device that sits between the internet and the website server. It filters traffic and enforces security policies. Examples include Cisco ASA and Fortinet FortiGate.
  • Software firewall: A software firewall is installed directly on the server. It provides the same functionality as a hardware firewall but is typically less expensive. Examples include iptables and Windows Firewall.
  • Cloud-based firewall: A cloud-based firewall is a virtual firewall that resides in the cloud. It is managed by a third-party provider, who filters traffic before it reaches the website server. Examples include Cloudflare and Akamai.


Implementing a website firewall is an effective way to enhance website security and reduce the risk of cyber attacks. Website owners should review their website security regularly and ensure they have a firewall in place. By doing this, website owners can provide a safe and secure online experience for their users.

Setting up SSL certificates

One of the first steps to securing a website is setting up SSL (Secure Sockets Layer) certificates. SSL certificates authenticate your website's identity to ensure that all data transmitted between the website and its visitors is encrypted and secure. Here are some benefits of SSL certificates:

  • Security: SSL certificates ensure that your website is secure for users to visit and interact with. It encrypts all data exchanged between the website's server and the user's browser, making it difficult for anyone to steal data.

  • Trust: SSL certificates help to establish trust between the website and its visitors. When users see the green padlock icon and "https" in the address bar, they know that the website is secure, and they are more likely to trust it.

  • SEO ranking: Google has confirmed that SSL certificates are a ranking factor, meaning that websites with SSL certificates are more likely to rank higher in search engine results pages (SERPs).

Now that you know why SSL certificates are important, here's how to set them up:

  1. Purchase a certificate: You can purchase an SSL certificate from a Certificate Authority (CA) or from your web hosting provider. You can choose a certificate based on your website's size and needs.

  2. Install the certificate: The process of installing an SSL certificate will vary based on your web hosting platform. Your web hosting provider should offer instructions for installing a certificate, or you can hire an expert to do it for you.

  3. Configure your website: Once the certificate is installed, you need to configure your website to use it properly. Update your website's URLs to use HTTPS instead of HTTP, and ensure all links and resources are loaded over HTTPS.

  4. Validate your certificate: You may need to take additional steps to validate your SSL certificate to ensure it is trusted by web browsers. This usually involves verifying domain ownership or completing other validation procedures.

By following these steps, you can set up SSL certificates for your website and ensure that your visitors' data is safe and secure. Remember to renew your certificate periodically to ensure that it remains valid and trusted by web browsers.

Keeping WordPress and Plugins Updated

One of the most basic but crucial steps in maintaining website security is keeping WordPress and plugins updated. According to a study by Sucuri, outdated WordPress installations and plugins were the top cause of hacked websites in 2018, accounting for 36.7% of all incidents. This highlights the importance of staying up-to-date with software updates and patches.

WordPress and plugin updates often include security fixes for vulnerabilities that could be exploited by attackers. By keeping your website’s software updated, you reduce the risk of security breaches and ensure your website remains secure and functional.

To update WordPress and its plugins, simply log in to your WordPress dashboard and check for available updates in the Updates section. You can update individual plugins or select all available updates at once. Before updating, make sure to back up your website to avoid any loss of data.

It’s also essential to regularly review and uninstall any unused plugins, as they can become security risks if left unattended. In some cases, outdated plugins may need to be replaced with newer alternatives that provide similar functionality.

While updating WordPress and plugins may seem like a simple task, its importance cannot be overstated. Neglecting software updates can leave your website vulnerable to hacking attempts and expose sensitive data to cybercriminals. Make sure to keep your website’s software updated and stay proactive in maintaining website security.

Useful resources:

Enforcing strong passwords and user access controls

One of the easiest ways to protect your website is to enforce strong passwords and user access controls. A weak password is like leaving your front door unlocked, inviting unauthorized access to your site. In fact, according to a study by Verizon, stolen passwords are the leading cause behind 81% of hacking-related security breaches.

But what makes a password "strong" enough? It should be at least 12 characters long, contain a mix of uppercase and lowercase letters, numbers, and symbols. Avoid using commonly used words and phrases, either alone or in combination with other characters. Instead, use a passphrase - a sequence of words that you'll find easy to remember, but hard to crack.

User access controls are equally important. Limiting access to your website's back end to only those who need it will minimize the risk of unauthorized access. Create backup user accounts for emergency situations, and delete unused accounts that are no longer necessary.

Additionally, the use of multi-factor authentication (MFA), where users must enter a second form of identification in addition to a password, can greatly increase the security of your website. This could be through the use of a code sent via SMS, an authentication app such as Google Authenticator, or a physical security key.

It may seem like a hassle to enforce strong passwords and user access controls, but it's worth it. A little extra effort upfront can save you from a lot of trouble later on.

Some useful resources for enforcing strong passwords and user access controls:

Regularly backing up website content and databases

Backing up website content and databases is an essential part of website maintenance. Without backups, a website owner risks losing important data due to hacking incidents, server crashes, or accidental file deletions. Regular backups not only provide a sense of security but also allow website owners to restore their website and all of its content up to the most recent version.

According to a survey conducted by CodeGuard, a website backup and monitoring service, 60% of websites that lose data never recover. Another study by ITIC reveals that over 80% of companies suffering a major data loss shut down within three years.

Making backups is a straightforward process. The frequency of backups will depend on the amount of content and updates that are made to the website. A website that changes its content daily from a blog or has regular updates will need more frequent backups, whereas a brochure-style site with static content might only require monthly backups. Backup frequency is ultimately up to the website owner, so they need to find a balance and decide how much data loss they can afford.

Websites can be backed up through several ways, including manual backups, web hosting backups, and third-party backup plugins. Manually backing up a website, while it affords better control, can be time-consuming and vulnerable to errors. Web hosting backups can be convenient but are often limited on backup frequency and data restoration options. Third-party backup plugins, like UpdraftPlus or VaultPress, offer automatic backups with more robust features and easy data restoration options.

One vital aspect of creating backups is storing the data in a secure location. Backups can be stored locally, on a separate external drive, or in the cloud. It is essential to store backups in multiple locations to ensure their availability should one location become unavailable.

In conclusion, regularly backing up website content and databases is non-negotiable for website owners looking to safeguard their website. With proper backup schedules and dependable backup options, website owners can restore their website with ease, not having to worry about lost data and website downtime.

Using Secure Hosting Providers

Choosing a secure hosting provider is one of the most important steps in website security. It's essential to find a hosting provider that is reliable and has a strong reputation for security.

A secure hosting provider will have a range of features in place to protect their customers' websites, including:

  • Regular security updates and patches: Keeping servers and software up to date is critical for website security. Hosting providers should update their servers and software regularly to patch any vulnerabilities that could be exploited to gain unauthorized access to websites.

  • Firewalls and intrusion prevention: Firewalls can help block unauthorized access to servers and websites, while intrusion prevention can detect and stop attempts to exploit security vulnerabilities.

  • Malware and virus scanning: Hosting providers should also scan for malware and viruses to detect and remove any threats that could compromise website security.

It's important to note that not all hosting providers are created equal when it comes to security. A recent study found that 41% of websites that were hacked were on shared hosting, compared to just 6% on dedicated hosting. This highlights the importance of choosing a hosting provider that prioritizes security.

When choosing a hosting provider, it's important to consider factors such as:

  • Reputation: Look for hosting providers with a strong reputation for security and reliability. Research online reviews and check for any security breaches or issues in the provider's history.

Website security is crucial, but it's not a one-and-done deal. Once you've taken steps to secure your website, you need to continuously monitor it for malicious activity. According to a recent study, 43% of cyber attacks target small businesses, and that number is only expected to grow. Here are some ways to keep an eye on your website and stay ahead of cyber criminals.

Use a Security Plugin or Service

One of the simplest ways to monitor your website for malicious activity is by using a security plugin or service. There are many options available, ranging from free plugins like WordFence to paid services like Sucuri. These services can scan your website for known vulnerabilities, monitor for suspicious activity, and alert you if anything seems out of the ordinary.

Stay on Top of Notifications

If you're using a security plugin or service, be sure to stay on top of notifications. Take the time to review any alerts you receive and take action if necessary. It's also a good idea to review your server logs regularly. This can help you spot any suspicious activity before it becomes a problem.

Conduct Regular Security Audits

Conducting regular security audits is another important way to monitor your website for malicious activity. This involves reviewing your website's code, files, and server settings to ensure that everything is up-to-date and secure. If you're not comfortable doing this yourself, consider hiring a security expert to conduct the audit for you.

Set up Automated Backups

Having automated backups of your website content and databases is important for many reasons, including as a way to monitor for malicious activity. If you notice that something on your website has been compromised, you can always restore a backup to undo any damage. Just be sure to back up your website regularly to ensure that you have a recent backup to restore from.

Final Thoughts

Keeping your website secure is an ongoing process. By using security plugins or services, staying on top of notifications, conducting regular security audits, and setting up automated backups, you can monitor your website for malicious activity and keep your website and visitors safe.

Securing File and Directory Permissions

When it comes to website security, it is crucial to ensure that only authorized users have access to the files and directories on the server. This can be achieved through securing file and directory permissions.

File permissions determine who can read, write, or execute a file, while directory permissions determine who can access or modify a directory. It is important to note that improper file and directory permissions can lead to unauthorized access, modification, or deletion of files.

To secure file and directory permissions, here are some best practices to follow:

1. Set appropriate permissions

One of the most important steps in securing file and directory permissions is setting appropriate permissions. Generally, files should have a permission of 644 (read and write permission for the owner and read permission for others), while directories should have a permission of 755 (read, write, and execute permission for the owner and read and execute permission for others).

However, it is important to note that different files and directories may require different permissions based on their purpose. For example, executable files may require more restrictive permissions to prevent unauthorized modification.

2. Limit access to sensitive directories

Sensitive directories such as configuration files and user data should only be accessible to authorized users. This can be achieved by setting more restrictive permissions or using a .htaccess file to limit access.

3. Avoid using a root account

Using a root account to access files and directories can be dangerous as it provides unrestricted access to the server. Instead, create a separate user account with limited privileges to access files and directories.

4. Regularly audit and update permissions

Regularly auditing and updating file and directory permissions is crucial to ensure that only authorized users have access. This can be done through tools such as FileZilla or using command line tools such as chmod and chown.

By implementing these best practices, you can secure file and directory permissions and prevent unauthorized access to your website content.

Integrating CAPTCHA and Phishing Protection

CAPTCHA, an acronym for "Completely Automated Public Turing Test To Tell Computers and Humans Apart," is a valuable security feature that offers users robust protection against automated bots and phishing attacks.

Phishing attacks are one of the most common types of cyberattacks. According to a recent report from Symantec, more than 1.5 million new phishing websites are created each month, many of which are designed to steal sensitive personal and financial information.

Integrating CAPTCHA protection can provide an additional layer of security to your website, making it much more difficult for hackers to infiltrate your site and steal sensitive data.

CAPTCHA comes in a variety of different formats, including the classic "I'm not a robot" click box, math problems, and image recognition puzzles, to name a few. In general, the more challenging the CAPTCHA, the better protection it provides.

Many major companies, including Google, have also begun adopting advanced CAPTCHA algorithms that use machine learning to dynamically protect against evolving cyber threats.

If you're using a popular platform like WordPress, there are many great plugins available that can help you integrate CAPTCHA protection into your site. For example, the "Advanced noCaptcha & invisible Captcha" plugin by KeyCaptcha is a popular choice for WordPress users.

One important thing to keep in mind when integrating CAPTCHA protection is to make sure you're not making it too difficult for legitimate users to access your site. It's generally a good idea to limit the use of CAPTCHA to high-risk areas, such as login pages and contact forms.

In addition to using CAPTCHA, it's always a good idea to implement other phishing protection measures, such as email filtering and educating users about what to look for in phishing emails.

By integrating CAPTCHA and other security measures into your website, you can significantly reduce your risk of falling victim to phishing attacks and other types of cyber threats.
