A security analyst is investigating an incident that involves multiple alerts from different data sources: a firewall log showing a connection to a known malicious IP, an endpoint alert showing a suspicious file download, and a CASB log showing data upload to a cloud storage service. The analyst wants to determine if these are part of the same attack. What is the most reliable way to establish the correlation?

Look for common entities, such as the same source IP address or user account, across all three alerts.

Verify that all alerts were generated within the same hour.

Ensure that all alerts are from the same data source.

Check if all alerts have the same severity level.

A threat hunter is looking for signs of a new malware family that is not yet in any threat intelligence feeds. The malware is known to communicate with a specific domain pattern and uses unusual process execution. Which approach in Cortex XSIAM would be most effective for this hunt?

Create a BIOC rule that detects any new process execution on endpoints.

Build a query that searches for network connections to domains matching the pattern and correlates with process execution data.

Use the incident correlation features to find similar alerts from the past.

Search for the malware's file hash in the IOC database.

What is a behavioral indicator of compromise (BIOC)?

A list of known malicious IP addresses

A vulnerability score assigned to a system

A type of firewall rule that blocks certain applications

A pattern of behavior that may indicate malicious activity, even if no known IOC is present

A threat hunter at a healthcare organization is using Cortex XSIAM to look for signs of lateral movement. The hunter suspects that an attacker is using PowerShell to execute commands on multiple endpoints. Which query approach would be most effective to identify this activity?

Query the IOC database for known malicious PowerShell scripts.

Use a BIOC rule that detects unusual PowerShell activity on a single endpoint.

Search for PowerShell execution events across all endpoints, then correlate with network connections to other hosts.

Search for any process named 'powershell.exe' in the last 24 hours.

A security analyst notices that a user account is accessing a large number of files in a short period, which is unusual for that user. The analyst wants to determine if this is a potential data exfiltration or just a legitimate activity. Which Cortex XSIAM feature would be most helpful in this investigation?

Threat hunting queries to search for other users with similar activity.

Correlation rules to match the activity to known attack patterns.

IOC matching to see if the files accessed are known malicious.

Behavioral analytics to compare the user's current activity to their historical baseline.
