Where is an XML firewall most commonly and effectively deployed in the environment?
An XML firewall is most commonly deployed between the firewall and the application server to validate XML messages and guard against various XML-based threats before they reach the application server. This placement ensures that the XML content is checked for security issues after passing through the general network security perimeter but before it can impact the application, making it the most effective deployment location.
B. Between the presentation and application layers
D. Between the firewall and application server
D: Between FW and application server
The correct Answer is A ( between the application and data layer ). Please Google it.
An XML firewall is designed to filter, validate, and secure XML-based communications (e.g., SOAP, RESTful APIs) before they reach the application. The best placement for an XML firewall is between the traditional firewall and the application server so that it can inspect and filter malicious or malformed XML traffic before it reaches the backend systems. Why Not the Others? A. Between the application and data layers: The XML firewall is meant to protect applications before they interact with the database, not after. B. Between the presentation and application layers: XML firewalls operate at the network/API level, not within the user interface or presentation layers. C. Between the IPS and firewall: An Intrusion Prevention System (IPS) operates at a broader security level, while an XML firewall specifically targets XML and web service attacks. Placing it before a general firewall wouldn’t be effective.
