Azure Cloud integration with SIEM Tools
Hi Everyone,
I am currently researching on SIEM tools that could be integrated with Azure cloud. Are there any SIEM tools that could be integrated with Azure cloud in providing monitoring solution? If yes could anyone elaborate on how it is done and what are all the costs to be considered when setting up the solution using the SIEM tool. (VMs, Configuration, Storage and data, Hosting, Installation, Maintenance and upgrades)
Thank you 🙂
Akshaya_Kumar In order for you to evaluate 3rd party SIEM tools (like Splunk etc) to ingest data from Azure, you need to think what all you will ingest. You can categorize data sources into 3 buckets:
1.) Azure platform data: logs from O365, AAD, Activity logs etc fall into this bucket
2.) Azure reource data: this is where you diagnostic data from VMs etc will come from
3.) Finally you need to think of guest OS data like security logs, syslog etc
All this data need to be quantified as Splunk or any tool for that matter will charge you on data ingested per day. This is needed for not only licensing for SIEM tools but for Azure Event Hub where the data will hit before getting forwarded to SIEM tool. If you want to use Splunk, there is a Azure monitor addon for Splunk that can gather data from Azure event hub. Check Azure price calculator for Event hub costing. If you are hosting SIEM on azure, there will be IaaS, disk cost etc.
Hope this helps
Hello, Akshaya_Kumar
Is there any specific requirement to look for a SIEM tool that integrates with Azure cloud rather using the monitoring services provided by Azure? like Azure monitor and sentinel ?
- Yes. I know Azure sentinel can provide such service. I wanna know if there is any way we can use ArcSight or Splunk for that and integrate with Azure Cloud to do so. Any other SIEM tool other than the above 2 would also help. Earlier Arcsight could be integrated with Azure using Skyformation but its support will end soon and I wanna know if there is any other way to do so.
Hi, actually there are many tools that can integrates with Azure monitor, among arcsight, splunk, dynatrace.
check the information in the following article to get more details about each integration status.
