Scenario: A Citrix Engineer wants to protect a web application using Citrix Web App Firewall. After the Web App Firewall policy is bound to the virtual server, the engineer notices that Citrix Web App Firewall Is NOT blocking bad requests from clients.
Which tool can help the engineer view the traffic that is passing lo and from the client?
nstrace is the correct tool to use for viewing the traffic passing to and from the client when troubleshooting Citrix Web App Firewall. This tool captures network traffic at the packet level, allowing detailed analysis of the data being transmitted. It is particularly useful for identifying issues with traffic flow, which can help determine why the Web App Firewall is not blocking bad requests as expected. Other tools, like syslog, nsconmsg, and aaad.debug, do not provide the same level of detailed traffic capture needed for this type of analysis.
A. nstrace The nstrace tool is used on Citrix ADC to capture network traffic passing through the appliance. This tool can help the engineer analyze the traffic to and from clients, which can be useful in determining why Citrix Web App Firewall is not blocking bad requests as expected. It captures packets at the network level and provides detailed information that can be used to troubleshoot network or application issues, including Web App Firewall behavior.
Configure Syslog policy to segregate Web App Firewall logs The Web App Firewall offers you an option to isolate and redirect the Web App Firewall security log messages to a different log file. This might be desirable if the Web App Firewall is generating many logs, making it difficult to view other NetScaler log messages. You can also use this option when you are interested only in viewing the Web App Firewall log messages and do not want to see the other log messages. To redirect the Web App Firewall logs to a different log file, configure a syslog action to send the Web App Firewall logs to a different log facility. You can use this action when configuring the syslog policy, and bind it globally for use by Web App Firewall.
