Understanding Web Application Firewall (WAF) – The Top WAF Services You Can Use

The web application firewall is not the same as the regular firewall that you can install on your device. With the regular firewall, you can protect your device from various attacks that might put it at risk, especially hacker attacks that can cause various problems to your privacy and security. However, WAF or web application firewall deals only with the protection against various threats on a web application. Yes, instead of being installed on a device, WAF is used to protect a web application to ensure that it always runs without any problem.

The web application firewall has been used by most of the companies that run their software or applications fully on the web in order to prevent various possible threats such as data loss, DDoS attacks, hacking, and other types of similar attacks. WAF works by preventing the malicious HTTP or HTTPS requests from entering your web application, which keeps the stability, security, and reliability of your web application for the users. Here are the top WAF services that you can use:

1. Protection Against DDoS And Data Loss Prevention

This is the common service that WAF can provide for you since it is designed to mitigate various possible online attacks that might try to stop your web apps from running properly. The protection against DDoS service will prevent you from having your web application from getting denials of service, and thus, being inaccessible by the users. It works by preventing any HTTP request exploits that can trigger the DDoS in your server. Also, the data loss prevention will prevent any threats from stealing your important user’s data and keep them intact and private for the users.

2. SSL Offloading And Logging

The SSL offloading service is the type of web application firewall service that allows you to offload the workload of your web application to another server. This is usually done to process requests from the SSH and HTTP in a much faster way, providing the users with the ease of use of your web applications. By doing this, you can ensure that the users can access your apps more quickly without lagging. The logging service allows you to provide different types of logging for your web apps and make it easier for the users to access it in various ways.

3. Geo-location Blocking And Server Load Balancing

Another service that is worth mentioning is the Geo-location blocking, which allows you to block certain regions from accessing your web application. With this service activated, you will be able to block the region that might try to attack your server repeatedly. In this way, such an attack cannot be repeated, allowing you to keep your web application safe. Also, the server load balancing service allows you to put less strain on your physical servers by balancing the workload between physical and virtual servers. This can ensure more stability to your apps and provide more ease for you to keep the security protection on the high level.

4. Server Cloaking And Authentication

The web application firewall can also provide the server cloaking service that allows you to hide some unnecessary data from the HTTP headers. It gives more privacy for the users and it allows you to display the data that is important for the server. The authentication service allows you to put less strain on the server by offloading the authentication tasks to another server, allowing you to use the servers fully for data processing. Not only WAF is capable of protecting your web application security, it is also capable of keeping your servers in the stable state.

5. Compliance Check And Sandbox Integration

The compliance check service is the part of the WAF service that allows you to meet all the compliance standards as required by the authorities without having to fulfill such standards manually. The compliance check is already included in the WAF system and you don’t need to set it up for individual web application. The sandbox integration service helps you to create the sandbox environment for the highly suspicious traffic before they are processed in the server. It means that any potential threats will be isolated even before they can be executed on your web application. It is like the quarantine feature that is included in your regular antivirus or firewall software.

Those are the top WAF services that you can use. By understanding more about web application firewall, you can ensure that your web apps are safe from various potential threats and keep it running in a stable and reliable state.
