Where is an XML firewall most commonly deployed in the environment?
XML firewalls are most commonly placed between the firewall and the application server. This placement allows the XML firewall to inspect and validate XML traffic before it reaches the application server, protecting against various XML-based threats such as XML injection and denial-of-service attacks targeting XML messaging. By filtering and controlling XML content at this point, it ensures secure and reliable communication between the external network and the application server.
You can't put a solution like XML firewall in the theoretical space between layer 6 & 7 of OSI model, it doesn't make sense
For reference, an XML firewall is a specialized device used to protect applications exposed through XML based interfaces like REST and scan XML traffic coming into and going out from an organization. Typically deployed in a DMZ environment an XML Firewall is often used to validate XML traffic, control access to XML based resources, filter XML content and rate limit requests to back-end applications exposed through XML based interfaces.
A web application firewall (WAF - protected behind XML and SQL injection) is typically placed between the application and the presentation layers of the OSI (Open Systems Interconnection) model. The OSI model is a framework that is used to describe how data is transmitted over a network. It is divided into seven layers, each of which performs a specific set of functions to enable communication between devices.
XML Firewall is an appliance so A and C are eliminated. XML is an application of interest. D places the appliance in the most applicable location in the topology.
C. Between the presentation and application layers
REMOVE.
why not C
An XML firewall is designed to manage and secure XML traffic, which is commonly associated with web services and API interactions. The most appropriate deployment for an XML firewall is C
