最新的 Security Operations XSIAM-Engineer 免費考試真題 (Q92-Q97):

問題 #92
A financial institution is implementing XSIAM and requires robust threat intelligence feed integration. They subscribe to several commercial and open-source threat intelligence platforms (TIPS) that provide indicators of compromise (IOCs) in various formats, including STIX/TAXII, CSV, and JSON via REST APIs. The goal is to enrich security alerts, proactively identify threats, and automate blocking actions. Which XSIAM integration strategy offers the most comprehensive and scalable solution for consuming these diverse threat intelligence feeds and enabling automated response?

A. Subscribe XSIAM directly to all STIX/TAXII servers. For CSV/JSON feeds, create custom XSIAM Correlation Rules to parse and extract IOCs from other ingested logs.
B. Utilize XSIAM's built-in threat intelligence connectors for common TIPs. For custom or proprietary feeds, develop custom XSIAM content packs that use XSIAM's Data Ingest APIs or pull via Python scripts within playbooks for parsing and populating XSIAM's Indicator objects and internal block lists.
C. Configure XSIAM to regularly pull CSV and JSON feeds via SFTP, then manually upload STIX/TAXII files. Use XSIAM's 'Indicator' object for storage, and playbooks for enrichment.
D. Forward all threat intelligence data to an intermediate SIEM, then configure the SIEM to send filtered IOCs to XSIAM via syslog for indicator creation.
E. Implement a custom external script to consolidate all threat intelligence feeds into a single CSV file, then import this file daily into XSIAM's Data Lake for analysis.

答案：B

解題說明：
XSIAM offers built-in connectors for many popular TIPS, simplifying integration. For feeds without native connectors, developing custom XSIAM content packs or leveraging playbooks with Python scripts calling REST APIs is the most robust and scalable approach. This allows for proper parsing, normalization, and population of XSIAM's native Indicator objects, which are crucial for automated enrichment, correlation, and response actions (e.g., pushing to firewalls or EDR for blocking). Manual uploads and reliance on intermediate SIEMs add unnecessary complexity and latency.

問題 #93
A company is integrating Cortex XSIAM with their existing security infrastructure, which includes a SIEM, a SOAR platform, and multiple Active Directory domains. The XSIAM Engine needs to collect identity data, network flow data, and endpoint telemetry. Which of the following data collection methods and configurations are most appropriate for ensuring comprehensive and efficient data ingestion by the XSIAM Engine?

A. Deploying a single Engine and configuring all data sources to send logs via unsecured Syslog over UDP to simplify initial setup.
B. Relying solely on existing SIEM forwarders to send all data to the XSIAM Engine, eliminating the need for direct integrations.
C. Configuring the XSIAM Engine to pull data directly from all devices via SNMP for all telemetry types.
D. Manually uploading CSV files of security logs to the XSIAM Engine's data ingestion API on a daily basis.
E. Utilizing Cortex XDR agents for endpoint telemetry, configuring network devices to forward NetFlow/lPFlX to the Engine, and deploying dedicated Identity Connectors for Active Directory integration.

答案：E

解題說明：
Option B describes the most effective and recommended approach for comprehensive data ingestion with Cortex XSIAM. Cortex XDR agents are the primary method for endpoint telemetry, providing rich context. Network devices forwarding NetFlow/IPFIX directly to the Engine is efficient for network visibility. Dedicated Identity Connectors (e.g., for Active Directory) are designed for secure and real-time identity data synchronization. Option A uses insecure Syslog and lacks depth. Option C is inefficient and often leads to data loss or delayed ingestion as the SIEM might not forward all necessary fields or in the optimal format. Option D is manual and not scalable for continuous ingestion. Option E is highly inefficient for large-scale data collection and is not suitable for all telemetry types.

問題 #94
A global enterprise uses XSIAM and has different security policies for its various business units (BUS). A new XSIAM detection rule, Malware_Execution_Attempt', is critical for all BUS. However, BU 'FinTech' uses a highly specialized financial application that, due to its sandboxed environment, generates benign process anomalies that are falsely triggering this rule. The SOC team wants to implement an exclusion that is: 1) specific to BU 'FinTech', 2) applies only to alerts, and 3) dynamically excludes specific 'process.hash' values that are known to be benign but vary slightly with each application update. Which combination of XSIAM features would best achieve this, and how would it be architected?

A. Architect the solution by: 1. Creating a new XSIAM 'Suppression Rule' that matches 'alert_name = AND 'source_ip IN 2. This rule's action would be 'Drop Alert'. 3. The rule would require manual updates for new benign hashes.
B. Architect the solution by: 1. Modifying the rule's KQL query to include a 'NOT' clause for 'source_bu = 'FinTech" and 'process.hash IN ('hashl', 'hash2', ...y.
C. Architect the solution by: 1. Creating a custom 'Asset Tag' for all FinTech assets. 2. Maintaining an external script that computes and updates an XSIAM 'External Dynamic List (EDL)' with benign process hashes from the FinTech application. 3. Creating an 'Exclusion' for the rule that uses an 'AND condition to match 'asset.tags CONTAINS 'FinTech" AND 'process.hash IN EDL('FinTech_Benign_Hashes')'.
D. Architect the solution by: 1. Lowering the severity of all alerts to 'Informational' for FinTech-specific assets.
E. Architect the solution by: 1. Developing a Cortex XSOAR playbook that, upon receiving a alert, checks if the alert originated from a FinTech asset. 2. If so, the playbook queries an external database of known benign FinTech hashes and, if a match is found, automatically closes the incident.

答案：C

解題說明：
Option A is the most comprehensive and resilient solution. It combines several key XSIAM features: 1. Asset Tagging : Allows for logical grouping of assets by BIJ, making the exclusion specific to FinTech without relying on volatile IP ranges. 2. External Dynamic List (EDL) : Solves the problem of dynamically changing benign process hashes. An external script automates the update of this list, ensuring the exclusion remains current without manual intervention. 3. Targeted Exclusion : Applying the exclusion directly to the rule with 'AND' conditions ensures that the exclusion is only triggered when both the asset belongs to FinTech and the process hash is on the dynamic benign list. This prevents broad exclusions and maintains detection fidelity for other malicious activities. Option B is less maintainable due to manual hash updates and rule modification. Option C is reactive and consumes XSOAR resources for every alert. Option D is too broad as it doesn't filter by process hash and requires manual updates. Option E only changes severity, not preventing alert generation, which is undesirable for false positives.

問題 #95
An XSIAM engineer is observing that a specific custom log source, which frequently contains corrupted or malformed log entries (e.g., incomplete JSON, truncated strings), is causing downstream XQL queries to fail or return inconsistent results, even though the Data Flow parser is designed to handle common cases. This impacts the reliability of security analytics. Which combination of Data Flow practices would best mitigate the impact of these malformed entries on data quality and query reliability, while ensuring valid data is still processed?

A. Option C
B. Option D
C. Option B
D. Option A
E. Option E

答案：C,E

解題說明：

問題 #96
An XSIAM administrator is reviewing the audit logs for user activity and notices suspicious API calls originating from a compromised service account. The API key associated with this service account has 'Security Operations Center - Admin' permissions. The immediate action is to revoke the compromised API key. Which of the following XSIAM commands or API operations would be used to revoke a specific API key, assuming you have the necessary administrative privileges?

A. Option E
B. Option D
C. Option B
D. Option A
E. Option C

答案：C,E

解題說明：
Both the XSIAM UI and the XSIAM API provide mechanisms to revoke API keys. Option B describes the direct IJI approach, which is straightforward for administrators. Option C describes the typical REST API approach for deleting a resource, where DELETE requests are used to revoke or remove API keys. Option A is a pseudocode function call that might be part of an SDK, but not a direct API endpoint. Option D is an extreme measure that would disrupt all API integrations and is not the targeted way to revoke a single key. Option E is an unsupported and dangerous method of configuration management.
