What Is and How Does a Web Application Firewall Operate?
A firewall that is specifically made to safeguard web applications and web-based services is known as a web application firewall. In order for it to function, communication between the user’s browser and the web application must be inspected and filtered.
Attacks such as denial of service, SQL injection, and cross-site scripting can all be thwarted with the use of a web application firewall. Additionally, it can aid in botnet and virus protection.
The majority of web application firewalls are either hardware appliances or software modules that operate on web servers.
What Are a Web Application Firewall’s Fundamental Purposes?
A security device known as a web application firewall is positioned in front of web servers to shield them from intrusions and harmful traffic. All incoming and outgoing communication is examined by the firewall, which stops any that is thought to be unlawful or malicious. Moreover, the firewall keeps an eye on everything that happens on the web server and records any questionable or harmful activities.
In contrast to a regular firewall, a web application firewall is made expressly to safeguard web servers. It has the ability to recognize and stop attempts to take advantage of holes in the web server.
In order to defend against assaults, the web application firewall can employ a number of techniques, including attack monitoring, honeypot deployment, botnet identification, and more.
