How to Add Security Headers to Website?

6 mins

Do you know that website headers can be used to improve security? By implementing security headers, you can help protect your website against attacks. But how to add one to a website?

Adding security headers to your website is vital to keeping your site safe from any potential threats. There are a few different types of security headers that you can use, and each one offers its own set of benefits.

The most common security header is the X-Frame-Options header, which helps to prevent clickjacking attacks.

This header tells the browser not to allow your site to be framed within another site, which can help protect your content and prevent malicious actors from being able to trick users into clicking on links that they might not otherwise click on.

What is an HTTP Security Header and How Does It Work?


If you’ve ever wondered what an HTTP security header is or how it works, you’re not alone. Though it may sound complicated, an HTTP security header is actually quite simple.

In short, it’s a piece of code that helps to protect your website from attacks. When a visitor tries to access your site, the security header checks to see if their browser is up to date.

If it isn’t, the visitor will be redirected to a page where they can update their browser. This may sound like a minor inconvenience, but it’s actually a major security measure.

By ensuring that all visitors have an up-to-date browser, you can help to prevent attacks that could potentially compromise your website.

So, the next time you see an HTTP security header, remember that it’s there to help keep your website safe.

The Benefits of Adding Security Headers to Your Website

There are a number of benefits to adding security headers to your website. 

Perhaps the most obvious benefit is that it can help to protect your site from attack. By adding an additional layer of security, you can help to deter hackers and other malicious actors from targeting your site.

In addition, security headers can also help to improve your site’s performance. By caching certain types of data, you can help to reduce the amount of time that it takes for your pages to load.

Finally, security headers can also play a role in improving your site’s usability. By ensuring that certain types of content are not blocked by browsers, you can help to ensure that your users have a better experience when they visit your site. 

Overall, adding security headers to your website can have a number of positive impacts.

The 10 Most Popular Security Headers for Websites

As the internet becomes increasingly complex, so does the task of keeping data safe and secure. Luckily, there are a number of security headers that can be used to help protect websites and the information they contain. Here are 10 of the most popular security headers:

  • Strict-Transport-Security: This header helps to ensure that all communications with a website are encrypted, making it more difficult for hackers to intercept data.
  • Content-Security-Policy: This header specifies which sources of content are allowed to be loaded on a page, helping to prevent malicious content from being injected into a website.
  • X-Content-Type-Options: This header prevents browsers from incorrectly detecting the type of content on a page, which can lead to vulnerabilities being exploited.
  • X-Frame-Options: This header prevents pages from being loaded inside of frames or iframes, which can be used by attackers to launch phishing attacks.
  • X-XSS-Protection: This header enables the browser’s built-in XSS protection, which can help to prevent malicious scripts from being executed.
  • Referrer-Policy: This header controls how much information is included in the referrer header, which can be used by attackers to track users’ browsing habits.
  • Expires: This header specifies how long a page’s contents should be cached by the browser, which can help to reduce load times and improve performance.
  • Cache-Control: This header controls how caching is handled by the browser, which can help to prevent sensitive information from being cached and potentially leaked.
  • Pragma: This header instructs browsers whether or not they should cache a page’s contents, which can help to reduce load times and improve performance.
  • Set-Cookie: This header instructs the browser to only accept cookies that have been set by the website itself, which can help to prevent third-party cookies from being accepted and potentially leaked.

How to Choose the Right Security Headers for Your Website?

As you can see, there are a wide variety of security headers available for websites, and choosing the right ones can be a daunting task.

However, by following a few simple steps, you can ensure that your website is properly protected.

  • First, take inventory of the information that your website contains. This includes sensitive data such as customer information, financial data, and anything else that would be considered confidential.
  • Once you know what type of data your website contains, you can narrow down the list of potential security headers.
  • Next, consider the threats that your website faces. This includes both external threats such as hackers and internal threats such as malicious employees.
  • For each type of threat, there are a number of different security header options available. By carefully evaluating the risks that your website faces, you can choose the headers that offer the best protection.
  • Finally, remember that no single header is perfect for all websites. The best security strategy is to choose a variety of headers that offer complementary protection.

By following these steps, you can choose the right security headers for your website and give yourself peace of mind knowing that your site is properly protected.

How to Add Security Headers to Your Website?

Websites are increasingly under attack from hackers. One way to protect your website is to add security headers. Security headers are special types of HTTP headers that help to secure your website by reducing vulnerabilities.


Here’s a step-by-step guide to adding security headers to your website: 

Step-1: Check to see if your website is already using security headers by running a security scan. 

Step-2: If security headers are not already in use, add them to your website’s code. 

Step-3: Be sure to test your website after adding security headers to ensure that they are working properly. 

Step-4: Keep your security headers up-to-date as new threats emerge.

By following these steps, you can help to keep your website safe from hackers.

Tip to Get the Most out Of Security Headers

Security headers are an important part of website security. They help to protect your website from malicious attacks and can also be used to improve your website’s performance.

However, many website owners are unaware of how to use security headers to their full potential. As a result, they may miss out on important benefits or even leave their website vulnerable to attack.

Here are some tips to help you get the most out of security headers on your website:

  • Use a secure server– A secure server is the first step in ensuring that your website is protected. Security headers can only do so much to protect your website if your server is not secure. Make sure that your server is using a strong encryption method and that it is regularly updated with the latest security patches.
  • Set up multiple layers of protection– Security headers should not be the only line of defense for your website.
    In addition to using security headers, you should also set up multiple layers of protection, such as firewalls and intrusion detection systems. This will help to ensure that your website is protected even if one layer of defense fails.
  • Keep your headers up-to-date– Security headers need to be regularly updated in order to be effective. Attackers are constantly finding new ways to bypass security measures.

So, it is important to keep your headers up-to-date in order to prevent them from being exploited. You can usually find the latest security header updates from your web service provider or through third-party security vendors.

By following these tips, you can help to ensure that your website is properly protected against attack and that you are getting the most out of security headers.
