So, how does a WAF function differently from a standard network firewall? An attacker could present legitimate HTTP requests to the web application, which successfully go through the standard Network firewall and reach your applications. Threats related to routing and the transmission of network communications (Internet Protocol, TCP & UDP) can quickly be averted using rules set up, such as IP origins, ports, and access control lists.Ī Web application firewall operates at layer 7 (application) of the OSI model and ensures the security of web applications from well-known threats. In the world of network security, we have standard network firewalls and Web Application Firewalls.Ī standard network firewall protects your entire network infrastructure and operates at layer 3 to 4 of the OSI/TCPIP model (network and transport). Web Application Firewalls Introductionįirewalls ensure the security of the network and its applications from well-known threats. For demonstration purpose, we focus here on the setup of a WAF on the platfrom Xelon HQ. This article introduces you to the World of Web Application Firewall and especially shows you how to setup a WAF on a Cloud Platform.
