CompTIA Cybersecurity Analyst (CySA+) Certification Exam Sample Questions (Q120-Q125):

NEW QUESTION # 120
During a security test, a security analyst found a critical application with a buffer overflow vulnerability. Which of the following would be best to mitigate the vulnerability at the application level?

  • A. Configure address space layout randomization.
  • B. Update third-party dependencies.
  • C. Implement input validation.
  • D. Perform OS hardening.

Answer: C

Explanation:
Implementing input validation is the best way to mitigate the buffer overflow vulnerability at the application level. Input validation is a technique that checks the data entered by users or attackers against a set of rules or constraints, such as data type, length, format, or range. Input validation can prevent common web application attacks such as SQL injection, cross-site scripting (XSS), or command injection, which exploit the lack of input validation to execute malicious code or commands on the server or the client side. By validating the input before allowing submission, the web application can reject or sanitize any malicious or unexpected input, and protect the application from being compromised.


NEW QUESTION # 121
Which of the following risk management decisions should be considered after evaluating all other options?

  • A. Mitigation
  • B. Avoidance
  • C. Acceptance
  • D. Transfer

Answer: C

Explanation:
* Risk Acceptance means acknowledging a risk and choosing not to take further action because the cost of mitigation may outweigh the benefits.
* It is the last resort when:
* The risk is low impact or unlikely to occur.
* Other options (mitigation, transfer, avoidance) are not feasible.
Why Not Other Options?
* A (Transfer) # Moving risk to a third party (e.g., insurance).
* C (Mitigation) # Implementing security controls to reduce risk.
* D (Avoidance) # Eliminating the risk entirely (e.g., discontinuing a service).


NEW QUESTION # 122
An employee received a phishing email that contained malware targeting the company. Which of the following is the best way for a security analyst to get more details about the malware and avoid disclosing information?

  • A. Hire an external consultant to perform the analysis
  • B. Use a local sandbox in a microsegmented environment
  • C. Upload the malware to the VirusTotal website
  • D. Share the malware with the EDR provider

Answer: B

Explanation:
Comprehensive Detailed Explanation:To safely analyze malware while avoiding unintended disclosure of company information, it is best to use a local sandbox in a microsegmented environment. Here's why:
* A. Upload the malware to the VirusTotal website
* Risk: VirusTotal and similar services are public and may share uploaded files with other security vendors, potentially exposing proprietary or sensitive information.
* B. Share the malware with the EDR provider
* Limitation: While EDR providers may offer insight, sharing potentially sensitive malware samples externally still introduces risk of disclosure or data leaks.
* C. Hire an external consultant to perform the analysis
* Cost and Risk: Hiring an external consultant can be costly and may introduce risks related to third-party handling of sensitive data. Although it may provide insights, this is typically not the most efficient initial response.
* D. Use a local sandbox in a microsegmented environment
* Explanation: A local sandbox provides a secure, isolated environment for malware analysis without exposing sensitive data outside the organization. Microsegmentation enhances security by further isolating the sandbox from the network, preventing lateral movement if the malware attempts to communicate externally.

NEW QUESTION # 123
After completing a review of network activity. the threat hunting team discovers a device on the network that sends an outbound email via a mail client to a non-company email address daily at 10:00 p.m. Which of the following is potentially occurring?

  • A. Irregular peer-to-peer communication
  • B. Data exfiltration
  • C. Abnormal OS process behavior
  • D. Rogue device on the network

Answer: B

Explanation:
Explanation
Data exfiltration is the theft or unauthorized transfer or movement of data from a device or network. It can occur as part of an automated attack or manually, on-site or through an internet connection, and involve various methods. It can affect personal or corporate data, such as sensitive or confidential information. Data exfiltration can be prevented or detected by using compression, encryption, authentication, authorization, and other controls1 The network activity shows that a device on the network is sending an outbound email via a mail client to a non-company email address daily at 10:00 p.m. This could indicate that the device is compromised by malware or an insider threat, and that the email is used to exfiltrate data from the network to an external party.
The email could contain attachments, links, or hidden data that contain the stolen information. The timing of the email could be designed to avoid detection by normal network monitoring or security systems.


NEW QUESTION # 124
A security team is concerned about recent Layer 4 DDoS attacks against the company website. Which of the following controls would best mitigate the attacks?

  • A. Deploy an IPS in the perimeter network.
  • B. Block the attacks using firewall rules.
  • C. Implement a load balancer.
  • D. Roll out a CDN.

Answer: D

Explanation:
Rolling out a CDN is the best control to mitigate the Layer 4 DDoS attacks against the company website. A CDN is a Content Delivery Network, which is a system of distributed servers that deliver web content to users based on their geographic location, the origin of the web page, and the content delivery server. A CDN can help protect against Layer 4 DDoS attacks, which are volumetric attacks that aim to exhaust the network bandwidth or resources of the target website by sending a large amount of traffic, such as SYN floods, UDP floods, or ICMP floods. A CDN can mitigate these attacks by distributing the traffic across multiple servers, caching the web content closer to the users, filtering out malicious or unwanted traffic, and providing scalability and redundancy for the website12.
