A web firewall is a service to prevent security incidents such as web hacking caused by a security vulnerability in a web source, unlike a firewall or IDS/IPS service.
In order to fundamentally address security incidents such as web hacking caused by web source vulnerabilities, it is difficult to do so, but it can be quite daunting for small and medium-sized businesses. Web firewall services are services that, based on application layer (Layer 7) analytics and normalization techniques, monitor traffic to the HTTP/HTTPS protocol to detect illegal attacks and block them before they reach a customer’s Web server.
The Web site is a key point connecting businesses and customers, open to all users 365″24 hours a day. However, this means that all sites are exposed to all external attacks. In particular, as the web becomes more common, the target of hacking incidents is also focused on websites.
