ISC2 CC Incident Response 1 — Questions and Answers
Question 1: What is the PRIMARY purpose of an incident response plan?
- To prevent all security incidents from occurring
- To provide a structured approach for managing security incidents (Correct answer)
- To replace the need for security monitoring tools
- To document all system vulnerabilities
Correct answer: To provide a structured approach for managing security incidents
An incident response plan provides a structured, predefined approach to detecting, containing, and recovering from security incidents.
Question 2: Which phase of the NIST incident response lifecycle involves identifying whether a security incident has actually occurred?
- Containment
- Eradication
- Detection and Analysis (Correct answer)
- Recovery
Correct answer: Detection and Analysis
The Detection and Analysis phase involves evaluating events to determine whether an actual security incident has occurred and understanding its scope.
Question 3: What does CSIRT stand for in cybersecurity?
- Cyber Security Incident Response Team
- Computer Security Incident Response Team (Correct answer)
- Critical Security Incident Reporting Tool
- Centralized Security Incident Review Team
Correct answer: Computer Security Incident Response Team
CSIRT stands for Computer Security Incident Response Team, the group responsible for coordinating an organization's response to security incidents.
Question 4: Which of the following BEST describes an Indicator of Compromise (IoC)?
- A software patch that fixes a known vulnerability
- A policy defining acceptable use of resources
- A forensic artifact suggesting a system has been breached (Correct answer)
- A tool used to scan networks for open ports
Correct answer: A forensic artifact suggesting a system has been breached
An Indicator of Compromise (IoC) is a forensic artifact or observable evidence that indicates a potential intrusion or security breach has occurred.
Question 5: During which incident response phase would you isolate an affected system from the network?
- Preparation
- Detection and Analysis
- Containment (Correct answer)
- Post-Incident Activity
Correct answer: Containment
Containment is the phase where affected systems are isolated to limit the spread and impact of the incident.
Question 6: What is the FIRST phase of the NIST SP 800-61 incident response lifecycle?
- Detection and Analysis
- Containment, Eradication, and Recovery
- Preparation (Correct answer)
- Post-Incident Activity
Correct answer: Preparation
Preparation is the first phase of the NIST incident response lifecycle, establishing the capability and resources needed before incidents occur.
Question 7: Which document outlines the specific roles, responsibilities, and procedures for responding to security incidents?
- Security Policy
- Business Impact Analysis
- Incident Response Plan (Correct answer)
- Risk Assessment Report
Correct answer: Incident Response Plan
An Incident Response Plan documents the specific procedures, roles, and responsibilities that guide an organization's response to security incidents.
