Tutorial / Cram Notes
Livestream allows analysts to create and run live hunting queries that continuously monitor data as it’s ingested. This real-time analysis helps in quickly identifying unusual activities or anomalies that could indicate a security threat.
Setting Up Livestream for Hunting Queries
To set up a Livestream session, follow these steps:
- Navigate to the Hunting blade in Microsoft Sentinel.
- Click on the “+ Add new hunting query” to create a custom query or select an existing one.
- Once your query is ready, select “Livestream” to run it continuously.
Best Practices for Livestream Hunting Queries
When using Livestream, consider the following best practices:
- Scope: Limit the query to a specific time frame or dataset to avoid being overwhelmed by data.
- Relevancy: Ensure the query is tailored to target the most relevant data sources and entities.
- Efficiency: Optimize queries for performance to prevent overuse of resources.
Here’s a basic example of a Livestream hunting query that looks for failed login attempts:
SigninLogs
| where ResultType != “0” // non-zero is typically a failure
| project TimeGenerated, Identity, Location, ResultDescription
Running this query on Livestream will display real-time failed login attempts, helping analysts spot potential brute force attacks.
Using Livestream in Threat Detection
Example Scenario: Detecting Anomalous Behavior
Consider a scenario where an organization wants to monitor for multiple failed logins followed by a successful login, which could indicate credential stuffing or brute force attacks. The Livestream query could look something like this:
SigninLogs
| where TimeGenerated >= ago(1h)
| summarize CountFailedLogins=countif(ResultType != “0”), CountSuccessLogins=countif(ResultType == “0”) by UserId
| where CountFailedLogins > 5 and CountSuccessLogins > 0
| project TimeGenerated, UserId, CountFailedLogins, CountSuccessLogins
By running this query in Livestream, the security team can observe this anomalous behavior as it occurs and immediately investigate.
Comparing Livestream to Traditional Hunting
| Traditional Hunting | Livestream Hunting |
|---|---|
| Analyzes historical data | Analyzes real-time streaming data |
| Runs queries on a schedule | Continuously runs queries |
| Requires manual intervention to execute query again | Automatic real-time data monitoring |
| Limited immediate threat response | Immediate detection enables quick threat response |
Conclusion
Livestream enhances the ability of security operations analysts to detect and respond to threats in real time. For those preparing for the SC-200 Microsoft Security Operations Analyst exam, understanding how to effectively implement and utilize Livestream in Microsoft Sentinel is essential. It empowers security teams with immediate insights into potential threats, enabling a more proactive and dynamic security posture.

Explanation: The main purpose of using Livestream is to enable real-time monitoring of potential threats so that security operations teams can identify and react to incidents as they occur.
3) True or False: You need to save a hunting query first to use it with Livestream.
- True
Correct Answer: True
Explanation: Before you can use a hunting query with Livestream, you need to save the query. This allows Livestream to execute the saved query against live data.
4) When using Livestream, how long can you monitor the live data stream for each query session?
- A) 1 hour
- B) 3 hours
- C) 24 hours
- D) Indefinitely, until manually stopped
Correct Answer: B) 3 hours
Explanation: Each Livestream query session allows you to monitor the live data stream for up to 3 hours, after which the session ends.
5) True or False: Livestream is capable of integrating with third-party threat intelligence feeds directly.
- False
Correct Answer: False
Explanation: Livestream is designed to monitor live data streams from sources within the Microsoft ecosystem. Integration with third-party threat intelligence feeds requires additional setup and is not a direct feature of Livestream.
6) Which role must your Azure AD account possess to use the Livestream feature in Microsoft 365 Defender?
- A) Global Administrator
- B) Security Reader
