XSIAM-Analyst Incident Handling And Response — Timed 20 Questions

Question 1

An analyst creates a custom XQL query to investigate unusual PowerShell execution across endpoints. The query needs to filter out known administrative scripts based on a lookup list stored in XSIAM. Which XQL command is best suited to enrich or filter the event stream using a lookup table?

20 minute time limit — choose an answer to begin.

Accepted Answer

lookup. The 'dedup' or 'filter' commands are useful, but enrichment and lookup matching against external lists in XSIAM XQL are performed using the 'lookup' command.

Answer

parse lookup_table

Answer

filter in_list

Answer

join

Question 2

While investigating a potential lateral movement attempt, an analyst wants to review the raw authentication logs associated with the incident in XSIAM. Which XQL dataset should the analyst query to examine Windows logon events?

Accepted Answer

dataset = endpoint_raw. The endpoint_raw dataset in XSIAM contains raw event data collected by Cortex agents, including Windows security event logs for authentication.

Answer

dataset = network_raw

Answer

dataset = cloud_audit_raw

Answer

dataset = xdr_data

Question 3

An analyst is writing an XQL query to search for failed login attempts followed within 5 minutes by a successful login from the same user account. Which XQL function should be used to correlate these sequential events within a timeframe?

Accepted Answer

correlate / seq command. Sequence-based analysis or matching events across time intervals in XQL is efficiently handled using the 'alt' or sequence/stream processing logic or specific commands like 'seq'.

Answer

stream join with time_window parameter

Answer

aggregate windowed_events

Answer

union match operator

Question 4

An analyst wants to investigate network traffic anomalies by reviewing top talkers by data volume across the enterprise. Which XSIAM tool or query approach should be used?

Question 9

When managing the incident lifecycle in XSIAM, an analyst determines that a triggered alert is a false positive and wants to prevent similar alerts from generating incidents in the future. What is the recommended action?

Accepted Answer

Change the incident status to Closed and tune the correlation rule or add an exception.. Analysts can resolve an incident and tune or suppress the underlying alert rule to prevent future occurrences of the same false positive.

Answer

Export the incident to CSV and purge local cache.

Answer

Delete the alert from the backend database using an administrative XQL delete command.

Answer

Disable the Cortex XDR agent on the affected endpoint.

Question 10

An XSIAM Analyst is reviewing the Incident Management dashboard and needs to understand why a specific high-severity incident was automatically merged with an existing one. Which XSIAM feature determines this grouping behavior?

Accepted Answer

Incident Stitching and correlation rules. XSIAM uses Incident Stitching and correlation rules to automatically group related alerts into a single incident based on shared indicators of compromise or entities.

Answer

XQL query aggregation limits

Answer

Manual aggregation policies

Answer

Cortex XDR agent policy versioning

Question 11

When reviewing security events in the XSIAM Incident View, an analyst notices that an event has a 'BIOC' tag. What does BIOC stand for in the context of XSIAM and Cortex XDR?

Accepted Answer

Behavioral Indicator of Compromise. BIOC stands for Behavioral Indicator of Compromise, which detects suspicious sequences of events or behaviors without relying solely on known file hashes.

Answer

Basic Incident Operations Center

Answer

Blocklist Indicator of Cyberattack

Answer

Binary Indicator of Code

Question 12

An incident response team wants to customize the incident severity scoring in XSIAM to better reflect organizational risk. Where are incident risk scoring and severity mapping configurations managed?

Answer

Agent Installation Settings

Answer

Role-Based Access Control (RBAC) definitions

Answer

Question 13

An analyst is investigating an incident where a suspicious file was dropped on a host. To verify if other hosts across the enterprise have seen this exact file hash, which XSIAM search tool should the analyst use?

Accepted Answer

Query Center using XQL to search endpoint datasets for the file hash. Global hash searches across all ingested endpoint telemetry in XSIAM are efficiently executed using Query Center (XQL) searching the endpoint datasets.

Answer
