ISACA Certified Cybersecurity Operations Analyst Sample Questions (Q26-Q31):

NEW QUESTION # 26
Which of the following is the MOST effective way to prevent man-in-the-middle attacks?

  • A. Enabling two-factor authentication
  • B. Implementing firewalls on the network
  • C. Changing passwords regularly
  • D. Implementing end-to-end encryption

Answer: D

Explanation:
The most effective way to preventman-in-the-middle (MitM) attacksis by implementingend-to-end encryption:
* Encryption Mechanism:Ensures that data is encrypted on the sender's side and decrypted only by the intended recipient.
* Protection Against Interception:Even if attackers intercept the data, it remains unreadable without the decryption key.
* TLS/SSL Usage:Commonly used in HTTPS to secure data during transmission.
* Mitigation:Prevents attackers from viewing or altering data even if they can intercept network traffic.
Incorrect Options:
* A. Changing passwords regularly:Important for account security but not directly preventing MitM.
* B. Implementing firewalls:Protects against unauthorized access but not interception of data in transit.
* D. Enabling two-factor authentication:Enhances account security but does not secure data during transmission.
Exact Extract from CCOA Official Review Manual, 1st Edition:
Refer to Chapter 5, Section "Network Security Measures," Subsection "Mitigating Man-in-the-Middle Attacks" - End-to-end encryption is the primary method to secure communication against interception.


NEW QUESTION # 27
Following a ransomware incident, the network teamprovided a PCAP file, titled ransom.pcap, located in theInvestigations folder on the Desktop.
What is the name of the file containing the ransomwaredemand? Your response must include the fileextension.

Answer:

Explanation:
See the solution in Explanation.
Explanation:
To identify thefilename containing the ransomware demandfrom theransom.pcapfile, follow these detailed steps:
Step 1: Access the PCAP File
* Log into the Analyst Desktop.
* Navigate to theInvestigationsfolder located on the desktop.
* Locate the file:
ransom.pcap
Step 2: Open the PCAP File in Wireshark
* LaunchWireshark.
* Open the PCAP file:
mathematica
File > Open > Desktop > Investigations > ransom.pcap
* ClickOpento load the file.
Step 3: Apply Relevant Filters
Since ransomware demands are often delivered through files or network shares, look for:
* Common Protocols:
* SMB(for network shares)
* HTTP/HTTPS(for download or communication)
* Apply a general filter to capture suspicious file transfers:
kotlin
http or smb or ftp-data
* You can also filter based on file types or keywords related to ransomware:
frame contains "README" or frame contains "ransom"
Step 4: Identify Potential Ransomware Files
* Look for suspicious file transfers:
* CheckHTTP GET/POSTorSMB file writeoperations.
* Analyze File Names:
* Ransom notes commonly use filenames such as:
* README.txt
* DECRYPT_INSTRUCTIONS.html
* HELP_DECRYPT.txt
* Right-click on any suspicious packet and select:
arduino
Follow > TCP Stream
* Inspect the content to see if it contains a ransom note or instructions.
Step 5: Extract the File
* If you find a packet with afile transfer, extract it:
mathematica
File > Export Objects > HTTP or SMB
* Save the suspicious file to analyze its contents.
Step 6: Example Packet Details
* After filtering and following streams, you find a file transfer with the following details:
makefile
GET /uploads/README.txt HTTP/1.1
Host: 10.10.44.200
User-Agent: Mozilla/5.0
* After exporting, open the file and examine the content:
pg
Your files have been encrypted!
To recover them, you must pay in Bitcoin.
Read this file carefully for payment instructions.
README.txt
Step 7: Confirm and Document
* File Name:README.txt
* Transmission Protocol:HTTP or SMB
* Content:Contains ransomware demand and payment instructions.
Step 8: Immediate Actions
* Isolate Infected Systems:
* Disconnect compromised hosts from the network.
* Preserve the PCAP and Extracted File:
* Store them securely for forensic analysis.
* Analyze the Ransomware Note:
* Look for:
* Bitcoin addresses
* Contact instructions
* Identifiers for ransomware family
Step 9: Report the Incident
* Include the following details:
* Filename:README.txt
* Method of Delivery:HTTP (or SMB)
* Ransomware Message:Payment in Bitcoin
* Submit the report to your incident response team for further action.


NEW QUESTION # 28
An insecure continuous integration and continuous delivery (CI/CD) pipeline would MOST likely lead to:

  • A. security monitoring failures.
  • B. software Integrity failures.
  • C. browser compatibility Issues.
  • D. broken access control.

Answer: B

Explanation:
An insecure CI/CD pipeline can lead to software integrity failures primarily due to the risk of:
* Code Injection:Unauthenticated or poorly controlled access to the CI/CD pipeline can allow attackers to inject malicious code during build or deployment.
* Compromised Dependencies:Automated builds may incorporate malicious third-party libraries or components, compromising the final product.
* Insufficient Access Control:Without proper authentication and authorization mechanisms, unauthorized users might modify build configurations or artifacts.
* Pipeline Poisoning:Attackers can alter the pipeline to include vulnerabilities or backdoors.
Due to the above risks, software integrity can be compromised, resulting in the distribution of tampered or malicious software.
Incorrect Options:
* B. Broken access control:This is a more general web application security issue, not specific to CI/CD pipelines.
* C. Security monitoring failures:While possible, this is not the most direct consequence of CI/CD pipeline insecurities.
* D. Browser compatibility Issues:This is unrelated to CI/CD security concerns.
Exact Extract from CCOA Official Review Manual, 1st Edition:
Refer to Chapter 6, Section "DevSecOps and CI/CD Security", Subsection "Risks and Vulnerabilities in CI
/CD Pipelines" - Insecure CI/CD pipelines can compromise software integrity due to code injection and dependency attacks.


NEW QUESTION # 29
Which of the following processes is MOST effective for reducing application risk?

  • A. Regular code reviews throughout development
  • B. Regular monitoring of application use
  • C. Regular vulnerability scans after deployment
  • D. Regular third-party risk assessments

Answer: A

Explanation:
Performingregular code reviews throughout developmentis the most effective method for reducing application risk:
* Early Detection:Identifies security vulnerabilities before deployment.
* Code Quality:Improves security practices and coding standards among developers.
* Static Analysis:Ensures compliance with secure coding practices, reducing common vulnerabilities (like injection or XSS).
* Continuous Improvement:Incorporates feedback into future development cycles.
Incorrect Options:
* A. Regular third-party risk assessments:Important but does not directly address code-level risks.
* C. Regular vulnerability scans after deployment:Identifies issues post-deployment, which is less efficient.
* D. Regular monitoring of application use:Helps detect anomalies but not inherent vulnerabilities.
Exact Extract from CCOA Official Review Manual, 1st Edition:
Refer to Chapter 6, Section "Secure Software Development," Subsection "Code Review Practices" - Code reviews are critical for proactively identifying security flaws during development.


NEW QUESTION # 30
Robust background checks provide protection against:

  • A. distributed dental of service (DDoS) attacks.
  • B. phishing.
  • C. insider threats.
  • D. ransomware.

Answer: C

Explanation:
Robust background checks help mitigateinsider threatsby ensuring that individuals withaccess to sensitive data or critical systemsdo not have a history of risky or malicious behavior.
* Screening:Identifies red flags like past criminal activity or suspicious financial behavior.
* Trustworthiness Assessment:Ensures that employees handling sensitive information have a proven history of integrity.
* Insider Threat Mitigation:Helps reduce the risk of data theft, sabotage, or unauthorized access.
* Periodic Rechecks:Maintain ongoing security by regularly updating background checks.
Incorrect Options:
* A. DDoS attacks:Typically external; background checks do not mitigate these.
* C. Phishing:An external social engineering attack, unrelated to employee background.
* D. Ransomware:Generally spread via malicious emails or compromised systems, not insider actions.
Exact Extract from CCOA Official Review Manual, 1st Edition:
Refer to Chapter 4, Section "Insider Threat Management," Subsection "Pre-Employment Screening" - Background checks are vital in identifying potential insider threats before hiring.
