Configuring the Web App Firewall (WAF) and Firewall History

Overview

A Web Application Firewall (WAF)‘s role is to filter incoming requests to a HTTP server. This module analyzes the requests received by using a database of request rules considered as unwanted.

You can enable or disable the web application firewall and customize its rules. It is also possible to view the firewall history of each domain.

Note : The Glossary of N0C contains explanations on multiple topics and can be consulted to clarify certain terms.
