Protection against Website Firewalls
You need a website firewall regardless of what type of website you have, no matter if it’s static or dynamic, e-commerce or blog. This article will show you why.
What is a website firewall?
Let’s begin with the basics. What is a website firewall? It’s a firewall that protects your website from the internet. It monitors both outgoing and inbound HTTP traffic and attempts to block any that it deems unsafe.
A website firewall, also known as a web application firewall or WAF, is a similar idea to proxy servers. Website firewalls are similar to proxy servers, which act as intermediaries between clients and malicious servers.
What protection does a firewall provide?
The website firewall does not provide a complete website security solution. However, it protects against many threats to web apps (layer 7 of the OSI 7 layer model). These vulnerabilities include SQL injection, cross-site scripting (XSS), and cross-site forgery. A website firewall should be used in conjunction with other security tools. This will protect all layers of the network, as is common with security tools for websites.
What is the actual function of a firewall on a website?
A website firewall is a rules-based defense. It will tell you what to block and/or allow through, and it will do the rest. Website firewalls targeted at the SMB market are generally pre-configured, but you can customize the configuration if necessary.
If your website was the victim of a distributed denial-of-service (DDoS), and you identify a common factor, such as IPs from certain countries where you have few or no customers, you may choose to temporarily block that country (or permanently)
SMBs will be able to easily and quickly modify their policies using the best web firewalls so they can respond to evolving attack vectors.
Whitelists versus Blacklists
The website firewall checks HTTP traffic against specified criteria to determine if it is safe. If it passes, it’s allowed to continue, otherwise, it is blocked. Only traffic that has been explicitly identified as safe will be allowed to pass under the whitelisting policy model.
Each approach has its advantages and disadvantages. The good news is that you don’t need to choose between the two. Modern website firewalls allow you to do both. This allows you to retain the broad protection of blacklisting, while also allowing faster data transfer between your site and sites you know are safe. It gives you the best of both.
Different types of website firewalls
Website firewalls generally fall under one of three main categories.
The same server hosts the host-based website firewall. This allows for tight integration and high levels of customization. However, it can drain server resources. Companies are faced with the dilemma of choosing between a faster server or slower page load times that could lead to customers leaving and a decrease in search ranking.
A network-based site firewall is typically implemented as a piece of hardware. This reduces server load and reduces latency. However, it is the most costly option. You also have to deal with physical equipment and must have a Plan A in the event of a hardware failure. You could be completely exposed and suffer potentially devastating consequences.
A cloud-based site firewall is often the best choice for SMBs, and sometimes for enterprises. It is easy to set up a cloud-based website firewall.
After your account is activated, the standard level protection will be available. This is assuming that you have chosen a reliable provider. This can be customized to your specific needs and wants. Cloud-based services will place the load on back-end servers, rather than your local hardware.
Website vulnerability scanners and firewalls
Although you can purchase a website firewall by itself, it is more practical and economical to buy an all-in-one website scanner. Each company will have its version of the theme, however, any good website vulnerability scanner will include both a firewall and anti-malware software.
