Question 1

Which of the following responsibilities does the legal team have during an incident management event? (Select two).

ACoordinate additional or temporary staffing for recovery efforts.

BReview and approve new contracts acquired as a result of an event.

CAdvise the incident response team on matters related to regulatory reporting.

DEnsure all system security devices and procedures are in place.

EConduct computer and network damage assessments for insurance.

FVerify that all security personnel have the appropriate clearances.

Answer : B, C

The legal team plays a crucial role in managing the legal and compliance aspects of incident response. They review and approve contracts (B) for emergency services, like incident response firms, and provide guidance on regulatory reporting (C), ensuring the organization meets compliance requirements. According to CompTIA Security+ guidelines, legal teams focus on regulatory and contractual matters rather than operational aspects like staffing (A) or security procedures (D).

Question 2

An organization identifies a method to detect unexpected behavior, crashes, or resource leaks in a system by feeding invalid, unexpected, or random data to stress the application. Which of the following best describes this testing methodology?

AReverse engineering

BStatic

CFuzzing

DDebugging

Answer : C

Fuzzing is a testing technique where invalid or random data is inputted into a system to find vulnerabilities, crashes, or unexpected behaviors. It's commonly used in software security to identify flaws that could lead to security breaches. According to CompTIA's CySA+ curriculum, fuzzing is a dynamic testing method for exposing application weaknesses. Options like static testing (B) involve analyzing code without execution, while reverse engineering (A) and debugging (D) involve different methodologies for understanding or fixing code, not intentionally stressing it.

Question 3

A SOC team lead occasionally collects some DNS information for investigations. The team lead assigns this task to a new junior analyst. Which of the following is the best way to relay the process information to the junior analyst?

AAsk another team member to demonstrate their process.

BEmail a link to a website that shows someone demonstrating a similar process.

CLet the junior analyst research and develop a process.

DWrite a step-by-step document on the team wiki outlining the process.

Answer : D

Documenting the process in a step-by-step format on the team wiki ensures the junior analyst has a clear, repeatable reference. This approach also supports consistency and accuracy, and the documentation can be updated or referenced by other team members as needed. CompTIA emphasizes the importance of procedural documentation in both CySA+ and Security+ for ensuring team members have reliable resources for task execution, which aids in knowledge retention and standardized practices across the team.

Question 4

Which of the following in the digital forensics process is considered a critical activity that often includes a graphical representation of process and operating system events?

ARegistry editing

BNetwork mapping

CTimeline analysis

DWrite blocking

Answer : C

Timeline analysis in digital forensics involves creating a chronological sequence of events based on system logs, file changes, and other forensic data. This process often uses graphical representations to illustrate and analyze how an incident unfolded over time, making it easier to identify key events and potential indicators of compromise. This approach is highlighted in CompTIA Cybersecurity Analyst (CySA+) practices as crucial for understanding the scope and sequence of a security incident. The other options do not involve chronological or graphical analysis to the extent that timeline analysis does.

Question 5

A company patches its servers using automation software. Remote SSH or RDP connections are allowed to the servers only from the service account used by the automation software. All servers are in an internal subnet without direct access to or from the internet. An analyst reviews the following vulnerability summary:

Which of the following vulnerability IDs should the analyst address first?

Answer : B

The vulnerability with the highest CVSS score and an active exploit is Microsoft CVE-2021-34527 (PrintNightmare). Although only present on two instances, its high severity (8.4) and exploitable nature make it a priority. PrintNightmare is a well-known remote code execution vulnerability, which can be a critical risk. According to CompTIA CySA+ and vulnerability management practices, prioritizing based on severity and exploitability is essential, even over the number of instances. Other vulnerabilities listed are less severe or lack active exploitation.

Question 6

Which of the following responsibilities does the legal team have during an incident management event? (Select two).

ACoordinate additional or temporary staffing for recovery efforts.

BReview and approve new contracts acquired as a result of an event.

CAdvise the Incident response team on matters related to regulatory reporting.

DEnsure all system security devices and procedures are in place.

EConduct computer and network damage assessments for insurance.

FVerify that all security personnel have the appropriate clearances.

Answer : B, C

During an incident, the legal team plays a crucial role in handling regulatory compliance and reviewing legal implications, such as contractual obligations and reporting requirements. Advising on regulatory reporting (Option C) ensures the organization meets legal mandates, while reviewing contracts (Option B) can address new or emergency services needed during the incident. According to CompTIA CySA+ and Security+ guidelines, these legal responsibilities are vital for compliance and risk management. Options related to staffing, damage assessments, and clearances typically fall under operational or HR responsibilities rather than legal purview.

Question 7

Which of the following best explains the importance of the implementation of a secure software development life cycle in a company with an internal development team?

AIncreases the product price by using the implementation as a piece of marketing

BDecreases the risks of the software usage and complies with regulatory requirements

CImproves the agile process and decreases the amount of tests before the final deployment

DTransfers the responsibility for security flaws to the vulnerability management team

Answer : B

A Secure Software Development Life Cycle (SDLC) integrates security measures at each stage of development to reduce vulnerabilities and improve the overall security of the software. This is essential for minimizing risks related to software usage and ensuring compliance with regulatory requirements, which is particularly important for organizations handling sensitive data. As per CompTIA standards, a Secure SDLC helps prevent security breaches and protects both the organization and its users from potential harm. Options A, C, and D do not accurately describe the primary goals of a Secure SDLC, which primarily centers on risk reduction and regulatory compliance.
