What is NetScaler App Firewall?

Citrix NetScaler App Firewall is an application security solution that blocks known and unknown attacks which target web and web service applications. Placed directly in front of web servers, the solution analyses all traffic between the application and user in both directions without requiring any modification to applications including secure connections.

Why use NetScaler App Firewall?

The Application Firewall hybrid security model blocks all known and day-zero application-layer attacks. Any web application behaviour which deviates from normal application use is treated as potentially malicious and blocked. A second level of protection efficiently scans the traffic against thousands of automatically updated signatures.
Below are the key defences employed by a NetScaler Application Firewall.

• Cross-Site Scripting
• Cross-Site Request Forgery
• SQL Injection
• XML Security
• Buffer Overflow
• Data Theft

In addition, Application Firewall ensures Payment Card Industry Data Security Standards (PCI-DSS) compliance through its PCI-DSS support and reporting tool. The compliance reporting tool shows Application Firewall settings relevant to PCI-DSS, how they should be configured and if they are being met. If a setting is found to be non-compliant, Application Firewall provides steps to rectify the situation. At a glance it is easy to determine if credit card blocking has been enabled and whether confidential fields have been configured and activated.
