Windows Firewall logs are enabled, but they do not show up in Sentinel

[SalmanKhan]

Hello,

We have MMA agent installed on 26 windows server, but we are not getting into Sentinel.

I can not see any table named "WindowsFirewall" either.

Do the tables appear when data starts pouring in, or it is now depreciated in Sentinel?

Have you told the MMA to start collecting data, the 2 ways of doing that are:

1. Look under Advanced settings, in your screen shot and add the Event Logs items you need

2. Enable a Azure Sentinel connector

Do you have any data from the Agents, if you do it should be in the Heartbeat table:

Heartbeat
| summarize count(), arg_max(TimeGenerated,*) by Computer

@CliveWatson Thanks for the prompt response.

Yes, I have configured Event logs and I can see output when I run the heartbeat query that you have mentioned. Following is the configuration for event logs - I have added everything that says "Firewall" to be safe, but it still does not help. 

 If you see below, this is how the front page of Sentinel looks like:

 

Is it possible that I need to tune it on the windows firewall (on the servers) as well, so that they are sent over to Sentinel?

Logs configured as you have done, go into the Events Table

Event
| summarize count() by EventLog

,
Have you looked here, this is how we ask you to configure this in Sentinel? https://docs.microsoft.com/en-us/azure/sentinel/connect-windows-firewall

@CliveWatson Thanks a lot.

I have now removed the collection via event-logs and have now configured Data Connector for Windows Defender Firewall with Advanced Security. Should it take some time before I see logs  coming in?

Would it also help in getting the map "Potential malicious events" to get live?

Thanks for your help Clive :) Much appreciated.

That map shows up when you have data in at least one of these Tables:

W3CIISLog

DnsEvents

WireData

WindowsFirewall

VMConnection

CommonSecurityLog

to check:

union isfuzzy=true  
W3CIISLog,
DnsEvents,
WireData,
WindowsFirewall,
VMConnection,
CommonSecurityLog
