Every new web application involving the exchange of data between servers increases your exposure to cybersecurity threats. A web application firewall (WAF) can help.
What does a web application firewall do? It protects you against potential security hazards. Unlike a classic firewall working at the network level, a WAF protects you at the application level.
Cybersecurity threats WAFs protect against include:
More on what does a web application firewall do:
WAFs also protect your technology against unwanted SQL injections, cross-site scripting, and the Open Web Application Security Project (OWASP) top 10.
How does a web application firewall work?
WAFs come in several formats: hardware, software, cloud-based, or any combination thereof. How a web application firewall works is by operating a set of policies—instructions, essentially—that analyze inbound traffic and determine whether it’s legitimate or should be blocked.
WAFs recognize suspicious data sent via HTTP/HTTPS—and blocks that data. These policies are typically set up in one of three different models exemplifying how does a web application firewall work:
The WAF scans your web applicants to filter out any potential threats or attacks—blocking access to the vulnerability. From there, the vulnerability still needs to be addressed directly. In a nutshell, this is how a web application firewall works.
