最新的 Security Operations XSIAM-Engineer 免費考試真題 (Q45-Q50):

問題 #45
A security analyst needs to install a Cortex XSIAM agent on a critical Linux server. The server is hardened and has no internet access, but can reach a local HTTP server hosting the agent installer. The analyst wants to ensure the agent is installed with a specific proxy configuration and is immediately assigned to the 'Critical _ Servers' agent group. Which command combination is most appropriate?

答案:B

解題說明:
Option E is the most accurate and complete. Cortex XSIAM agent installers for Linux typically accept parameters like '-proxy-string' (or similar, depending on version) to define proxy settings and 'group-name' to assign the agent to a specific group. A crucial element missing in other options (or incorrectly represented) is the installation token, which is unique to your XSIAM tenant and required for agent registration. While HTTP PROXY environment variable might work for swgetTcurl&, the agent installer itself needs explicit parameters for its own communication. The 'token" parameter is mandatory for the agent to register with your specific XSIAM instance. The exact parameter names might vary slightly with XSIAM versions, but '--proxy-string', '--group-name' , and '--token' are standard concepts.


問題 #46
An internal audit identified a gap in detecting privilege escalation attempts using Windows built-in tools like 'seclogon.exe' (RunAs) or psexec.exe' (Sysinternals) when used by non-administrative users. These tools are legitimate but often abused. The goal is to detect Process.Name' 'seclogon.exe' or 'psexec.exe' being invoked from a standard user context, especially when followed by an attempt to execute a sensitive command on another system or elevate privileges locally. Which XQL query would effectively capture this behavior as a BIOC, minimizing false positives from legitimate IT operations?

答案:D

解題說明:
Option B is the most effective and precise XQL query. Option A is too broad and will generate many false positives from legitimate use of these tools by non-admin users for non-privileged tasks. Option C is too generic for psexec and misses seclogon. Option D is specific but misses other malicious uses. Option E is very broad and will generate many false positives. Option B accurately uses the 'pattern' command to look for the specific sequence: 'seclogon.exe' or 'psexec.exe' being invoked by a non-admin user (stage 1), immediately followed (within 10 seconds, and from the same host/user) by attempts to execute privilege-escalation-related commands (stage 2). The 'where stage_l -Process.Reputation != 'trusted' and stage_2.Process.Reputation != 'trusted'' further refines the detection by excluding known good executables, significantly reducing false positives while catching the intended behavior.


問題 #47
An administrator wants to verify the specific policy rules currently applied to a running process named finance_app.exe on a Windows endpoint.
Which Cytool command should be used?

答案:D

解題說明:
To query policy/security behavior for an executable, use cytool policy query <image_name>. Palo Alto's docs describe cytool policy query notepad.exe for querying policy for an executable.

問題 #48
A Security Operations Center (SOC) is leveraging Palo Alto Networks XSIAM and wants to automate the enrichment of IP addresses found in alerts with threat intelligence from multiple external sources (e.g., AbuselPDB, VirusTotal). The current marketplace content pack for threat intel enrichment only supports a single source. Which of the following approaches is the most efficient and scalable to integrate additional threat intelligence feeds and ensure their consistent application to new alerts?

答案:D

解題說明:
Option E is the most efficient and scalable. Developing a custom integration (or extending an existing one) that can act as a multi- source orchestrator centralizes the logic for querying multiple threat intelligence sources. This approach allows for easy addition or removal of sources by simply updating configuration parameters within the integration, rather than requiring new playbooks or separate integrations for each source. This maintains a clean and maintainable content pack structure. Options A and C are less scalable and maintainable. Option B is a valid approach but less efficient than extending an existing pack. Option D describes data ingestion, not necessarily enrichment within the existing marketplace content pack structure.


問題 #49
An XSIAM engineer is managing a rule that detects 'Suspicious PowerShell Execution'. This rule is generating an unusually high number of false positives on developer machines due to legitimate administrative scripts. The requirement is to maintain detection for malicious PowerShell but ignore benign developer activity. The challenge is that developers use a wide variety of script names and parameters, making simple exclusion lists impractical. Which content optimization strategy, incorporating a dynamic approach, would be most suitable?

答案:A

解題說明:
Option C offers the most robust and dynamic solution. A 'Profile-based' detection within XSIAM (often leveraging IJEBA or baselining capabilities) allows for understanding the normal behavior of specific entities (like developer workstations). By baselining legitimate PowerShell usage on these machines, the system can more accurately identify true anomalies or malicious activity without requiring constant manual updates of exclusion lists. It also allows for correlation with other indicators like access to sensitive data, which further refines the detection. Option A is impractical due to the dynamic nature of developer scripts. Option B is prone to evasion. Options D and E are obviously unacceptable for security.
