ISACA Certified Cybersecurity Operations Analyst Sample Questions (Q127-Q132):

NEW QUESTION # 127
An organization has received complaints from a number of its customers that their data has been breached.
However, after an investigation, the organization cannot detect any indicators of compromise. The breach was MOST likely due to which type of attack?

A. Zero-day attack
B. Supply chain attack
C. injection attack
D. Man-in the-middle attack

Answer: B

Explanation:
Asupply chain attackoccurs when a threat actor compromises athird-party vendoror partner that an organization relies on. The attack is then propagated to the organization through trusted connections or software updates.
* Reason for Lack of Indicators of Compromise (IoCs):
* The attack often occursupstream(at a vendor), so the compromised organization may not detect any direct signs of breach.
* Trusted Components:Malicious code or backdoors may be embedded intrusted software updatesor services.
* Real-World Example:TheSolarWinds breach, where attackers compromised the software build pipeline, affecting numerous organizations without direct IoCs on their systems.
* Why Not the Other Options:
* B. Zero-day attack:Typically leaves some traces or unusual behavior.
* C. injection attack:Usually detectable through web application monitoring.
* D. Man-in-the-middle attack:Often leaves traces in network logs.
CCOA Official Review Manual, 1st Edition References:
* Chapter 6: Advanced Threats and Attack Techniques:Discusses the impact of supply chain attacks.
* Chapter 9: Incident Response Planning:Covers the challenges of detecting supply chain compromises.

NEW QUESTION # 128
Which ofthe following is .1 PRIMARY output from the development of a cyber risk management strategy?

A. Mitigation activities are defined.
B. Business goals are communicated.
C. Accepted processes are Identified.
D. Compliance implementation is optimized.

Answer: A

Explanation:
Theprimary output from the development of a cyber risk management strategyis thedefinition of mitigation activitiesbecause:

* Actionable Plans:Clearly defineshow to reduce risk exposure, including implementing controls, patching vulnerabilities, or conducting training.
* Strategic Guidance:Aligns mitigation efforts with organizational goals and risk tolerance.
* Continuous Improvement:Provides a structured approach to regularly update and enhance mitigation practices.
Other options analysis:
* A. Accepted processes are identified:Important, but the primary focus is on defining how to mitigate risks.
* B. Business goals are communicated:The strategy should align with goals, but the key output is actionable mitigation.
* C. Compliance implementation is optimized:Compliance is a factor but not the main result of risk management strategy.
CCOA Official Review Manual, 1st Edition References:
* Chapter 5: Risk Management and Mitigation:Highlights the importance of defining mitigation measures.
* Chapter 9: Strategic Cyber Risk Planning:Discusses creating a roadmap for mitigation.

NEW QUESTION # 129

Explanation:
Regularly reviewing firewall rules ensures that outdated, redundant, or overly permissive rules are identified and removed.
* Reduced Attack Surface:Unnecessary or outdated rules may open attack vectors.
* Compliance and Policy Adherence:Ensures that only authorized communication paths are maintained.
* Performance Optimization:Reducing rule clutter improves processing efficiency.
* Minimizing Misconfigurations:Prevents rule conflicts or overlaps that could compromise security.
Incorrect Options:

NEW QUESTION # 130
The network team has provided a PCAP file withsuspicious activity located in the Investigations folderon the Desktop titled, investigation22.pcap.
What is the filename of the webshell used to control thehost 10.10.44.200? Your response must include the fileextension.

Answer:

Explanation:
See the solution in Explanation.
Explanation:
To identify thefilename of the webshellused to control the host10.10.44.200from the provided PCAP file, follow these detailed steps:
Step 1: Access the PCAP File
* Log into theAnalyst Desktop.
* Navigate to theInvestigationsfolder located on the desktop.
* Locate the file:
investigation22.pcap
Step 2: Open the PCAP File in Wireshark
* LaunchWiresharkon the Analyst Desktop.
* Open the PCAP file:
mathematica
File > Open > Desktop > Investigations > investigation22.pcap
* ClickOpento load the file.
Step 3: Filter Traffic Related to the Target Host
* Apply a filter to display only the traffic involving thetarget IP address (10.10.44.200):
ini
ip.addr == 10.10.44.200
* This will show both incoming and outgoing traffic from the compromised host.
Step 4: Identify HTTP Traffic
* Since webshells typically use HTTP/S for communication, filter for HTTP requests:
http.request and ip.addr == 10.10.44.200
* Look for suspiciousPOSTorGETrequests indicating a webshell interaction.
Common Indicators:
* Unusual URLs:Containing scripts like cmd.php, shell.jsp, upload.asp, etc.
* POST Data:Indicating command execution.
* Response Status:HTTP 200 (Success) after sending commands.
Step 5: Inspect Suspicious Requests
* Right-click on a suspicious HTTP packet and select:
arduino
Follow > HTTP Stream
* Examine the HTTP conversation for:
* File uploads
* Command execution responses
* Webshell file namesin the URL.
Example:
makefile
POST /uploads/shell.jsp HTTP/1.1
Host: 10.10.44.200
User-Agent: Mozilla/5.0
Content-Type: application/x-www-form-urlencoded
Step 6: Correlate Observations
* If you identify a script like shell.jsp, verify it by checking multiple HTTP streams.
* Look for:
* Commands sent via the script.
* Response indicating successful execution or error.
Step 7: Extract and Confirm
* To confirm the filename, look for:
* Upload requests containing the webshell.
* Subsequent requests calling the same filename for command execution.
* Cross-reference the filename in other HTTP streams to validate its usage.
Step 8: Example Findings:
After analyzing the HTTP streams and reviewing requests to the host 10.10.44.200, you observe that the webshell file being used is:
shell.jsp
Final Answer:
shell.jsp
Step 9: Further Investigation
* Extract the Webshell:
* Right-click the related packet and choose:
mathematica
Export Objects > HTTP
* Save the file shell.jsp for further analysis.
* Analyze the Webshell:
* Open the file with a text editor to examine its functionality.
* Check for hardcoded credentials, IP addresses, or additional payloads.
Step 10: Documentation and Response
* Document Findings:
* Webshell Filename:shell.jsp
* Host Compromised:10.10.44.200
* Indicators:HTTP POST requests, suspicious file upload.
* Immediate Actions:
* Isolate the host10.10.44.200.
* Remove the webshell from the web server.
* Conduct aroot cause analysisto determine how it was uploaded.

NEW QUESTION # 131
Which of the following is the MOST effective way to prevent man-in-the-middle attacks?

A. Changing passwords regularly
B. Implementing firewalls on the network
C. Enabling two-factor authentication
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.
