I am attempting the Splunk collection under Upskill. In the final lab i.e. Demonstrate your skill lab, I am getting stuck at a particular task. This is the prompt that I need to solve. The problem is there is no field for Destination IP in the log. Whenever I search according to the prompt, no results are returned and the question won't take 0 as an answer. Please help me move forward.92Views0likes2CommentsMicrosoft Sentinel Deployment & Log Ingestion: Ingesting Platform Logs via Diagnostic Settings
Hello Immersive Labs community, I’ve been working through the lab tasks and successfully completed tasks 1 through 6. However, I’m stuck on task 7, which asks: "A storage account has been deleted. What would be the data type of the generated log?" The task seems oddly described, and I can’t find any clear hints in the lab briefing or online resources. I’ve tried querying various data types like AzureActivity, AuditLogs, StorageBlobLogs, StorageFileLogs, and others, but none seem to fit correctly. Could anyone provide guidance or confirm which data type is actually relevant for this scenario? Are there any specific tips or resources I might be missing? Thanks in advance for your help!2KViews0likes1CommentNetwork Hardening Lab Recommendations
I've been looking for some good training resources for network hardening. I've been working through the Windows Hardening collection and found it really useful. Are there any other lab recommendations similar to this? In particular hardening things such as PfSense firewalls, Vyos routers, Linux endpoints etc.Solved103Views0likes3CommentsFIN7 Threat Hunting with Splunk: Ep.2 – Initial Access
