Bug in stand-alone MS Sentinel MITRE tactics
I setup a new Analytic rule where I had selected multiple tactics/techniques combinations. When I create an incident from that rule, only one of the tactics/techniques actually show up in the stand-alone MS Sentinel UI as well as in the SecurityIncident table. It isn't even the first one I selected; it is the last one. I did double check the Analytic rule and all the tactics/techniques are selected. If I look at the incident using the MS Sentinel REST API, it does show that all the tactics/techniques are there as well as if I look in the M365 portal (I have my MS Sentinel instance linked). Heck, even the Graph Query will show them all (after expanding the incident to show the alerts as well). Has anyone noticed this recently? Is it a bug or another new "feature"?
Parsing syslog
1. i am ingesting firewall logs as syslog and trying to parse out the fields accordingly using the split command, i have a problem that the beginig of the logs is not piped and i have made the split in 2 occasions. as you can see in the attached pic theFWD|UDP|p4| fields are nit parsed out. this is the _raw syslog message: Security F180 Block: FWD|UDP|p4|192.168.x,x|67|00:15:5d:0f:c4:01|255.255.255.255|68|bootpc||LAN-2-INTERNET|4017|0.0.0.0|0.0.0.0|0|1| 2. can you show me the same using normal regex i cant see in MSFT doc how to do it the old way 🙂 3. should i do the parsing on search time of the query? doesnt it increase the search time?Having issues with Run-MDEAntiVirus Playbook
Hi, I'm having issues getting the Run-MDEAntiVirus playbook working. I have created it using the Github template, assigned the managed instance rights to Sentinel and the Defender ATP. When it is triggered I get the following error message. From what I can see the post command is not sending over the MDATPDeviceId. The information from the entries Get-Hosts does provide the host and the MDATPDeviceId information so I'm a little lost on what is going on. Could anyone help me please? Regards MikeThe issue with displaying the original query in the newly created scheduled query rule
Hello everyone. I recently started learning Azure Sentinel, and I wanted to create my first custom rule. The rule works as I wanted, but I encountered an issue with displaying the original query. When an incident is created and I go to the "Incident Timeline" and click "Link to LA," my query is shown in an obfuscated form, as shown in the screenshot. Could you please help me figure out how to make the original query visible? Thank you!AWS WAF logs to Sentinel and the S3 Data Connector
Looking to get our AWF WAF logs into Sentinel but not really sure which route to take. Looking at the S3 data connector, there's only 4 data tables (VPCFlow, Guardduty, Cloudtrails, Cloudwatch) which makes me think I can't send these logs to an S3 bucket and have Sentinel ingest them as the logs won't be supported. What are my options here as far as getting these logs into the SIEM? Custom connectors? Thanks.
