Answer :

Here are 10 multiple-choice questions (MCQs) focusing on the topic of software requirements for engineering secure software, along with their solutions:

  1. What is the primary goal of security requirements in software engineering?
    A) To ensure functionality
    B) To prevent unauthorized access
    C) To enhance user experience
    D) To reduce the cost of development

    Solution: B) To prevent unauthorized access

    • Security requirements focus on safeguarding software from malicious activities and ensuring that only authorized users have access to certain functionalities or data.
  2. Which of the following is a common tool used for identifying security requirements?
    A) Gantt Chart
    B) Threat Modeling
    C) Fishbone Diagram
    D) SWOT Analysis

    Solution: B) Threat Modeling

    • Threat modeling is a technique used to identify, communicate, and understand threats and mitigations within the context of protecting something of value.
  3. What does the acronym CIA stand for in terms of security in software requirements?
    A) Confidentiality, Integrity, Availability
    B) Confidentiality, Integrity, Adaptability
    C) Control, Integrity, Availability
    D) Compliance, Integrity, Assurance

    Solution: A) Confidentiality, Integrity, Availability

    • These are the three pillars of security in information systems, ensuring that data is protected, maintains accuracy, and is accessible to authorized users when needed.
  4. Why is it important to consider security during the requirements engineering phase?
    A) It reduces overall development time
    B) It makes testing easier
    C) Security built in from the beginning is more effective
    D) It allows for easier user training

    Solution: C) Security built in from the beginning is more effective

    • Integrating security from the start helps to prevent potential breaches and vulnerabilities throughout the software's lifecycle.
  5. Which of the following is NOT a type of security requirement?
    A) Encryption requirement
    B) Privacy requirement
    C) Usability requirement
    D) Authentication requirement

    Solution: C) Usability requirement

    • While usability is an important aspect of software design, it is not specifically considered a security requirement.
  6. What is meant by 'security by design' in software engineering?
    A) Designing security features after deployment
    B) Incorporating security into the design process from the start
    C) Ignoring security in early stages
    D) Focusing only on user interface design

    Solution: B) Incorporating security into the design process from the start

    • Security by design involves embedding security measures during the design phase of software development to prevent vulnerabilities.
  7. Which role is primarily responsible for determining security requirements in a software project?
    A) Graphic Designer
    B) Software Developer
    C) Business Analyst
    D) Security Engineer

    Solution: D) Security Engineer

    • Security engineers play a crucial role in defining and implementing security measures in software projects.
  8. In what document are security requirements typically recorded during software development?
    A) Gantt Chart
    B) Data Flow Diagram
    C) Software Requirements Specification
    D) Use Case Diagram

    Solution: C) Software Requirements Specification

    • This document formally outlines the functions, behaviors, and attributes a system should possess, including security requirements.
  9. What is a common consequence of inadequate security requirements?
    A) Increased user satisfaction
    B) Higher development costs
    C) More efficient code
    D) Software vulnerabilities

    Solution: D) Software vulnerabilities

    • Poorly defined security requirements can lead to vulnerabilities, which can be exploited by attackers.
  10. Which of the following methods helps verify that security requirements have been met?
    A) Unit Testing
    B) Security Testing
    C) Beta Testing
    D) Load Testing

    Solution: B) Security Testing

    • Security testing involves evaluating the security measures and vulnerabilities of a software system to ensure requirements are met.

By answering these questions, students will gain a better understanding of the importance and implementation of security in software engineering.
