Run the following commands to enable the AppFlow feature, configure an AppFlow collector, action, and policy, and bind the policy globally or to the load balancing virtual server: Select the virtual servers that you want to enable security insight and click. The reason cross-site scripting is a security issue is that a web server that allows cross-site scripting can be attacked with a script that is not on that web server, but on a different web server, such as one owned and controlled by the attacker. Then, deploy the Web Application Firewall. Here we detail how to configure the Citrix ADC Web Application Firewall (WAF) to mitigate these flaws. The full OWASP Top 10 document is available at OWASP Top Ten. The HTML Cross-Site Scripting (cross-site scripting) check examines both the headers and the POST bodies of user requests for possible cross-site scripting attacks. The detection message for the violation, indicating the total requests received and % of excessive requests received than the expected requests, The accepted range of expected request rate range from the application. This protection applies to both HTML and XML profiles. The maximum length the Web Application Firewall allows in a requested URL. Also included are options to enforce authentication, strong SSL/TLS ciphers, TLS 1.3, rate limiting and rewrite policies. Based on the configured category, users can drop or redirect the bot traffic. Vulnerability scan reports that are converted to ADC Signatures can be used to virtually patch these components. If you never heard of VPC this stands for "Virtual Private Cloud" and it is a logical isolated section where you can run your virtual machines. The following figure shows the objects created in each server: Web and web service applications that are exposed to the Internet have become increasingly vulnerable to attacks. The application summary includes a map that identifies the geographic location of the server. In a Microsoft Azure deployment, a high-availability configuration of two Citrix ADC VPX instances is achieved by using the Azure Load Balancer (ALB). The Web Application Firewall examines the traffic to user protected websites and web services to detect traffic that matches a signature. While the external traffic connects to the PIP, the internal IP address or the NSIP is non-routable. The following steps assume that the WAF is already enabled and functioning correctly. If a Citrix ADC VPX instance with a model number higher than VPX 3000 is used, the network throughput might not be the same as specified by the instances license.
