ISACA Certified Cybersecurity Operations Analyst Sample Questions (Q128-Q133):

NEW QUESTION # 128
Which of the following should be completedFIRSTin a data loss prevention (OLP) system implementation project?

A. Data analysis
B. Deployment scheduling
C. Resource allocation
D. Data Inventory

Answer: D

Explanation:
Thefirst stepin aData Loss Prevention (DLP) implementationis to perform adata inventorybecause:
* Identification of Sensitive Data:Knowing what data needs protection is crucial before deploying DLP solutions.
* Classification and Prioritization:Helps in categorizing data based on sensitivity and criticality.
* Mapping Data Flows:Identifies where sensitive data resides and how it moves within the organization.
* Foundation for Policy Definition:Enables the creation of effective DLP policies tailored to the organization's needs.
Other options analysis:
* A. Deployment scheduling:Occurs after data inventory and planning.
* B. Data analysis:Follows the inventory to understand data use and flow.
* D. Resource allocation:Important but secondary to identifying what needs protection.
CCOA Official Review Manual, 1st Edition References:
* Chapter 6: Data Loss Prevention Strategies:Highlights data inventory as a foundational step.
* Chapter 7: Information Asset Management:Discusses how proper inventory supports DLP.

NEW QUESTION # 129
Which of the following BEST describes privilege escalation in the context of kernel security?

A. A technique used by attackers to bypass kernel-level security controls
B. A type of code to inject malware into the kernel
C. A process by which an attacker gains unauthorized access to user data
D. A security vulnerability in the operating system that triggers buffer overflows

Answer: A

Explanation:
Privilege escalationin the context of kernel security refers to:
* Kernel Exploits:Attackers exploit vulnerabilities in the kernel to gainelevated privileges.
* Root Access:A successful attack often results in root or system-level access.
* Bypassing Security:Kernel-level exploitation bypasses user-mode security controls, leading to complete system compromise.
* Common Methods:Exploiting buffer overflows, kernel vulnerabilities, or using rootkits.
Incorrect Options:
* A. Unauthorized access to user data:More related to data leakage, not privilege escalation.
* B. Buffer overflow vulnerabilities:A method of exploitation, not the result itself.
* C. Injecting malware:An attack vector, but not specifically privilege escalation.
Exact Extract from CCOA Official Review Manual, 1st Edition:
Refer to Chapter 4, Section "Kernel Security," Subsection "Privilege Escalation Techniques" - Attackers exploit kernel vulnerabilities to gain unauthorized elevated access.

NEW QUESTION # 130
In which cloud service model are clients responsible for regularly updating the operating system?

A. Database as a Service (OBaaS)
B. Platform as a Service (PaaS)
C. Software as a Service (SaaS)
D. Infrastructure as a Service (laaS)

Answer: D

Explanation:
In theIaaS (Infrastructure as a Service)model, clients are responsible formanaging and updating the operating systembecause:
* Client Responsibility:The provider supplies virtualized computing resources (e.g., VMs), but OS maintenance remains with the client.
* Flexibility:Users can install, configure, and update OSs according to their needs.
* Examples:AWS EC2, Microsoft Azure VMs.
* Compared to Other Models:
* SaaS:The provider manages the entire stack, including the OS.
* DBaaS:Manages databases without requiring OS maintenance.
* PaaS:The platform is managed, leaving no need for direct OS updates.
CCOA Official Review Manual, 1st Edition References:
* Chapter 10: Cloud Security and IaaS Management:Discusses client responsibilities in IaaS environments.
* Chapter 9: Cloud Deployment Models:Explains how IaaS differs from SaaS and PaaS.

NEW QUESTION # 131
Robust background checks provide protection against:

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

Answer: D

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.

NEW QUESTION # 132
The network team has provided a PCAP file withsuspicious activity located in the Investigations folderon the Desktop titled, investigation22.pcap.
What date was the webshell accessed? Enter the formatas YYYY-MM-DD.

Answer:

Explanation:
See the solution in Explanation.
Explanation:
To determine thedate the webshell was accessedfrom theinvestigation22.pcapfile, follow these detailed steps:
Step 1: Access the PCAP File
* Log into the Analyst Desktop.
* Navigate to theInvestigationsfolder on the desktop.
* Locate the file:
investigation22.pcap
Step 2: Open the PCAP File in Wireshark
* LaunchWireshark.
* Open the PCAP file:
mathematica
File > Open > Desktop > Investigations > investigation22.pcap
* ClickOpento load the file.
Step 3: Filter for Webshell Traffic
* Since webshells typically useHTTP/Sto communicate, apply a filter:
http.request or http.response
* Alternatively, if you know the IP of the compromised host (e.g.,10.10.44.200), use:
nginx
http and ip.addr == 10.10.44.200
* PressEnterto apply the filter.
Step 4: Identify Webshell Activity
* Look for HTTP requests that include:
* Common Webshell Filenames:shell.jsp, cmd.php, backdoor.aspx, etc.
* Suspicious HTTP Methods:MainlyPOSTorGET.
* Right-click a suspicious packet and choose:
arduino
Follow > HTTP Stream
* Inspect the HTTP headers and content to confirm the presence of a webshell.
Step 5: Extract the Access Date
* Look at theHTTP request/response header.
* Find theDatefield orTimestampof the packet:
* Wireshark displays timestamps on the left by default.
* Confirm theHTTP streamincludes commands or uploads to the webshell.
Example HTTP Stream:
POST /uploads/shell.jsp HTTP/1.1
Host: 10.10.44.200
User-Agent: Mozilla/5.0
Date: Mon, 2024-03-18 14:35:22 GMT
Step 6: Verify the Correct Date
* Double-check other HTTP requests or responses related to the webshell.
* Make sure thedate fieldis consistent across multiple requests to the same file.
2024-03-18
Step 7: Document the Finding
* Date of Access:2024-03-18
* Filename:shell.jsp (as identified earlier)
* Compromised Host:10.10.44.200
* Method of Access:HTTP POST
Step 8: Next Steps
* Isolate the Affected Host:
* Remove the compromised server from the network.
* Remove the Webshell:
rm /path/to/webshell/shell.jsp
* Analyze Web Server Logs:
* Correlate timestamps with access logs to identify the initial compromise.
* Implement WAF Rules:
* Block suspicious patterns related to file uploads and webshell execution.
