ISACA Certified Cybersecurity Operations Analyst Sample Questions (Q35-Q40):NEW QUESTION # 35
Which of the following should be considered FIRST when determining how to protect an organization's information assets?
  • A. The organization's business model
  • B. Results of vulnerability assessments
  • C. The organization's risk reporting
  • D. A prioritized Inventory of IT assets
Answer: A
Explanation:
When determining how to protect an organization's information assets, thefirst considerationshould be the organization's business modelbecause:
* Contextual Risk Management:The business model dictates thetypes of datathe organization processes, stores, and transmits.
* Critical Asset Identification:Understanding how the business operates helps prioritizemission-critical systemsand data.
* Security Strategy Alignment:Ensures that security measures align with business objectives and requirements.
* Regulatory Complianceifferent industries have unique compliance needs (e.g., healthcare vs.
finance).
Other options analysis:
* A. Prioritized inventory:Important but less foundational than understanding the business context.
* C. Vulnerability assessments:Relevant later, after identifying critical business functions.
* D. Risk reporting:Informs decisions but doesn't form the primary basis for protection strategies.
CCOA Official Review Manual, 1st Edition References:
* Chapter 2: Risk Management and Business Impact:Emphasizes considering business objectives before implementing security controls.
* Chapter 5: Strategic Security Planningiscusses aligning security practices with business models.

NEW QUESTION # 36
Which of the following is the BEST method for hardening an operating system?
  • A. Removing unnecessary services and applications
  • B. Manually signing all drivers and applications
  • C. Applying only critical updates
  • D. Implementing a host Intrusion detection system (HIOS)
Answer: A
Explanation:
Thebest method for hardening an operating systemis toremove unnecessary services and applications because:
* Minimizes Attack Surface:Reduces the number of potential entry points for attackers.
* Eliminates Vulnerabilities:Unused or outdated services may contain unpatched vulnerabilities.
* Performance Optimization:Fewer active services mean reduced resource consumption.
* Best Practice:Follow the principle ofminimal functionalityto secure operating systems.
* Security Baseline:After cleanup, the system is easier to manage and monitor.
Other options analysis:
* A. Implementing a HIDS:Helps detect intrusions but does not inherently harden the OS.
* B. Manually signing drivers:Ensures authenticity but doesn't reduce the attack surface.
* D. Applying only critical updates:Important but insufficient on its own. All relevant updates should be applied.
CCOA Official Review Manual, 1st Edition References:
* Chapter 9: Secure System Configuration:Emphasizes the removal of non-essential components for system hardening.
* Chapter 7: Endpoint Security Best Practicesiscusses minimizing services to reduce risk.

NEW QUESTION # 37
Your enterprise has received an alert bulletin fromnational authorities that the network has beencompromised at approximately 11:00 PM (Absolute) onAugust 19, 2024. The alert is located in the alerts folderwith filename, alert_33.pdf.
Use the IOCs to find the compromised host. Enter thehost name identified in the keyword agent.name fieldbelow.
Answer:
Explanation:
See the solution in Explanation.
Explanation:
To identify the compromised host using thekeyword agent.name, follow these steps:
Step 1: Access the Alert Bulletin
* Navigate to thealerts folderon your system.
* Locate the alert file:
alert_33.pdf
* Open the file with a PDF reader and review its contents.
Key Information to Extract:
* Indicators of Compromise (IOCs) provided in the bulletin:
* File hashes
* IP addresses
* Hostnames
* Keywords related to the compromise
Step 2: Log into SIEM or Log Management System
* Access your organization'sSIEMor centralized log system.
* Make sure you have the appropriate permissions to view log data.
Step 3: Set Up Your Search
* Time Filter:
* Set the time window toAugust 19, 2024, around11:00 PM (Absolute).
* Keyword Filter:
* Use the keywordagent.nameto search for host information.
* IOC Correlation:
* Incorporate IOCs from thealert_33.pdffile (e.g., IP addresses, hash values).
Example SIEM Query:
index=host_logs
| search "agent.name" AND (IOC_from_alert OR "2024-08-19T23:00:00")
| table _time, agent.name, host.name, ip_address, alert_id
Step 4: Analyze the Results
* Review the output for any host names that appear unusual or match the IOCs from the alert bulletin.
* Focus on:
* Hostnames that appeared at 11:00 PM
* Correlation with IOC data(hash, IP, filename)
Example Output:
_time agent.name host.name ip_address alert_id
2024-08-19T23:01 CompromisedAgent COMP-SERVER-01 192.168.1.101 alert_33 Step 5: Verify the Host
* Cross-check the host name identified in the logs with the information fromalert_33.pdf.
* Ensure the host name corresponds to the malicious activity noted.
The host name identified in the keyword agent.name field is: COMP-SERVER-01 Step 6: Mitigation and Response
* Isolate the Compromised Host:
* Remove the affected system from the network to prevent lateral movement.
* Conduct Forensic Analysis:
* Inspect system processes, logs, and network activity.
* Patch and Update:
* Apply security updates and patches.
* Threat Hunting:
* Look for signs of compromise in other systems using the same IOCs.
Step 7: Document and Report
* Create a detailed incident report:
* Date and Time:August 19, 2024, at 11:00 PM
* Compromised Host Name:COMP-SERVER-01
* Associated IOCsas per alert_33.pdf)
By following these steps, you successfully identify the compromised host and take initial steps to contain and investigate the incident. Let me know if you need further assistance!

NEW QUESTION # 38
Which of the following is theMOSTimportant component oftheasset decommissioning process from a data risk perspective?
  • A. Removing the monitoring of the assets
  • B. Informing the data owner when decommissioning is complete
  • C. Updating the asset status in the configuration management database (CMD8)
  • D. Destruction of data on the assets
Answer: D
Explanation:
Themost important component of asset decommissioningfrom adata risk perspectiveis thesecure destruction of dataon the asset.
* Data Sanitization:Ensures that all sensitive information is irretrievably erased before disposal or repurposing.
* Techniqueshysical destruction, secure wiping, or degaussing depending on the storage medium.
* Risk Mitigationrevents data leakage if the asset falls into unauthorized hands.
Incorrect Options:
* A. Informing the data owner:Important but secondary to data destruction.
* C. Updating the CMDB:Administrative task, not directly related to data risk.
* D. Removing monitoring:Important for system management but not the primary risk factor.
Exact Extract from CCOA Official Review Manual, 1st Edition:
Refer to Chapter 9, Section "Asset Decommissioning," Subsection "Data Sanitization Best Practices" - Data destruction is the most critical step to mitigate risks.

NEW QUESTION # 39
Which of the following services would pose the GREATEST risk when used to permit access to and from the Internet?
  • A. Server Message Block (5MB) on TCP 445
  • B. File Transfer Protocol(FTP) on TCP 21
  • C. Domain Name Service (DNS) on UOP 53
  • D. Remote Desktop Protocol (RDP) on TCP 3389
Answer: D
Explanation:
Remote Desktop Protocol (RDP)poses the greatest risk when exposed to the internet because:
* Common Attack Vector:Frequently targeted in brute-force attacks and ransomware campaigns.
* Privilege Escalation:If compromised, attackers can gain full control of the target system.
* Vulnerability History:RDP services have been exploited in numerous attacks (e.g., BlueKeep).
* Exploitation Riskirectly exposing RDP to the internet without proper safeguards (like VPNs or MFA) is extremely risky.
Incorrect Options:
* A. SMB on TCP 445:Risky, but usually confined to internal networks.
* B. FTP on TCP 21:Unencrypted but less risky compared to RDP for remote control.
* C. DNS on UDP 53:Used for name resolution; rarely exploited for direct system access.
Exact Extract from CCOA Official Review Manual, 1st Edition:
Refer to Chapter 5, Section "Remote Access Security," Subsection "RDP Risks" - Exposing RDP to the internet presents a critical security risk due to its susceptibility to brute-force and exploitation attacks.
