A firewall is a set of rules that controls incoming and outgoing traffic on a network or device. Firewalls can be hardware-based, software-based, or both. They are used to protect networks from unauthorized access and malicious activity.
WordPress is a content management system (CMS) that powers millions of websites worldwide. WordPress is open-source software that is free to use and easy to customize.
Most WordPress hosting providers include a basic firewall configuration as part of their service. However, you may need to configure additional firewall rules to protect your WordPress site from specific threats.
This article will show you how to set up a firewall for your WordPress site.
Step by Step Process to Install a Firewall on WordPress
Setting a firewall on WordPress is a great way to secure your site and prevent attacks. Many plugins and services can help you do this, but we recommend using a plugin called Wordfence.
1. Install & activate the wordfence WordPress plugin.
2. Go to the wordfence option. You will find that your wordfence plugin installation is incomplete.
3. Click on resume installation
4. You will see a popup like this. Put your email and click on continue. You need to put a valid email address because if any security issues occur, then wordfence will send you the alert notifications on this email.
5. If you have the license key, then put your key. If you don’t, then simply click on “No thanks.”
6. Now go to the firewall option
7. Click on click here to configure
8. A popup will appear & download the.htaccess file and click on continue.
9. Now, the firewall installation is complete.
10. Now scroll down and click on “Advanced Firewall Protection.”
11. Now, here are 3 options. Let’s discuss it step by step
Allow listed IP addresses that bypass all rules:
Allow listed IP addresses that bypass all rules is a feature in some firewalls that allows certain IP addresses to bypass all filtering rules. This can be useful if you want to allow access to a specific IP address or range of IP addresses while still blocking all other traffic.
However, it is important to be aware that malicious users can also abuse this feature. If you are not careful, you could end up allowing access to anyone who knows the right IP address.
For this reason, it is essential only to use this feature if you are sure that the IP addresses you are allowing are safe. Otherwise, you could be opening up your network to attack.
For example:
If you have a static IP address, you can allow that IP address to bypass all filtering rules.
This feature is often misunderstood. Sometimes some user put their broadband IP address. A Broadband IP address is not a static IP address, as it is subject to change after several weeks or months or even over a shorter period. Only use these features if you are sure that you have a permanent IP address.
Immediately block IPs that access these URLs
Immediately blocking IPs that access these URLs on a Firewall is a website security measure that can help to prevent attacks. When an attacker tries to access a protected website, the Firewall automatically blocks their IP address. This makes it difficult for them to access the site and its data. It can also help thwart attempts to DDOS the site by making it more difficult for attackers to target the site’s IP address. As a result, immediately blocking IPs that access these URLs on the Firewall is an important security measure that can help protect your website from attack.
This feature is useful for people trying to stop a specific hacker or trying to capture a hacker attempting to exploit a web-based vulnerability on a certain website or page. Note that you should not deliberately visit the banned URL when attempting to use the feature. As you will be blocked from your website instantly.
For example:
/example-vampire
If someone trying to access this URL then they will be blocked immediately. As URLs are case-sensitive, so a relative URL that begins with a forward slash must be specified. Wildcards (*) can be utilized if numerous malicious URLs are visited.
For example, if there are visits to:
/example-rock
/example-crow-draculla
Entering the wildcard below will prevent both of the URLs above:
/example-*
When using WordPress Multisite, wildcards (*) can be appended to the beginning of a URL to match requests on all associated domains. For example:
*/example-vampire
It will match links to the following URLs if they are all sites in the same Multisite where Wordfence is installed:
example.com/example-vampire
example.org/example-vampire
Ignored IP Address:
An ignored IP address is an address that has been specifically excluded from the firewall rules. This means that any traffic coming from or going to that address will not be inspected or blocked by the Firewall. Ignored IP addresses can be extremely useful when you need to allow traffic from a specific source but do not want to create a general rule that would allow all traffic from that source.
For example:
If you regularly run a scanning, uptime, or similar service against your site, then you do not want to receive an alert or increase your attack rate, then you can enter their IP address to get ignored by Wordfence. Ensure you trust the service as you are not going to get any alerts if your IP address is attacked.
Does WordPress have a firewall by default?
Yes. WordPress has a firewall system by default.
While WordPress is known for its ease of use and flexibility, it is also an incredibly secure platform. One of the ways WordPress protects itself from malicious attacks is by using a web application firewall (WAF).
A WAF is a software program that filters traffic to a website, looking for suspicious activity. If WP detects unusual or potentially harmful traffic, it will block the traffic from reaching the site. WordPress also regularly updates its core code and plugins, which helps to close any security holes that hackers might exploit. As a result, WordPress is a very secure platform, and it includes a firewall by default.
But in modern times, you should not only rely on WordPress’ security, you should also take your own measures to protect your website. For example, using a security plugin like Wordfence can help to secure your site further.
FAQs
Yes, it is.
Any website is susceptible to attack, no matter what content it holds. One of the most common ways hackers gain access to a website is through exposed vulnerabilities in the WordPress code. This is why it’s important to have a firewall installed on your WordPress website.
A firewall works by blocking malicious traffic before it ever reaches your website. This can help to prevent hackers from gaining access to your site and wreaking havoc. In addition, a firewall can also help to block automated attacks, such as denial-of-service attacks.
While no security measure is perfect, a firewall can be a valuable tool in protecting your WordPress website.
