SIMULATION 3
A company hosts various containerized applications for business uses. A client reports that one of its routine business applications fails to load the web-based login prompt hosted in the company cloud.
INSTRUCTIONS
Click on each device and resource. Review the configurations, logs, and characteristics of each node in the architecture to diagnose the issue. Then, make the necessary changes to the WAF configuration to remediate the issue.

The issue is with Web app 1 (Finance application).
From the WAF logs, we can see that requests to https://webapp1.comptia.org/FIN/login.html are being blocked (Rule ID 1006). The rule is configured to block access to the finance application's login page. This corresponds to the reported issue of the web-based login prompt not loading. To remediate the issue, the WAF configuration for Rule ID 1006 should be changed from "Block" to
"Allow". This will enable the web-based login prompt to load for the client. Additionally, the client app configuration indicates that the client laptop (IP 192.168.10.142) is trying to access the service, and the WAF logs show that requests from this IP are being blocked due to the current rule set. Changing the action for Rule ID 1006 will also ensure that legitimate attempts to access the login page from this IP are not blocked.
Steps for remediation:
Go to the WAF configuration.
Find Rule ID 1006 for the Finance application 1.
Change the action from "Block" to "Allow".
Save the changes.
