Guide: Incident Response and Forensics

What is Incident Response and Forensics?
Incident response and forensics are critical components of cybersecurity that involve detecting, managing and resolving security threats or breaches, and analyzing them to prevent recurrence. This process follows specific phases: preparation, identification, containment, eradication, recovery, and lessons learned.

Why is Incident Response and Forensics Important?
IR and forensics are key to ensuring that breaches are handled effectively and efficiently, minimizing damage to the organization and identifying how the breach occurred so similar incidents can be prevented in future.

How Does It Work?
It follows a sequence of phases: The preparation phase involves setting up an incident response team and plans. The identification phase is about detecting the breach. The containment phase focuses on limiting the damage. The eradication phase involves removing the threat from the system. The recovery phase ensures system restoration while the lessons learned phase reviews the incident to learn how to prevent future occurrences.

Exam Tips: Answering Questions on Incident Response and Forensics
Understanding the terminology and concepts is key. Be familiar with the phases of an incident response process. Understand the role of forensics in the incident response process – how evidence is gathered, preserved, analyzed and presented. Mastery of mitigation strategies, and knowing different types of cybersecurity incidents can also help you answer questions related to this topic more effectively.

For instance, questions may ask about the correct order of the phases, types of incidents, or the best containment strategies for different incidents. They may also ask about the methods and purposes of forensics in an incident response plan.

To summarize, good preparation, thorough understanding of the concepts, knowledge of key phases and forensics can assist you greatly in handling questions on incident response and forensics on the CISSP exam.

Question 1

An employee in your organization has reported receiving a suspicious email with a potentially malicious attachment. What is the most appropriate initial action to take?

Delete the email and ignore the situation Report the email to the security team and do not open the attachment Open the attachment to verify if it is malicious Forward the email to a trusted colleague for their opinion

Correct Answer: Report the email to the security team and do not open the attachment

The most appropriate initial action is to report the suspicious email to the security team and avoid opening the attachment to prevent potential harm.

Question 2

A data breach has just been detected in your organization. What is the immediate next step that should be taken in the Incident Response process?

Recovery Lessons learned Containment Eradiation

Correct Answer: Containment

In the incident response process, once a data breach has been detected (which corresponds to the Identification phase), the immediate next step is Containment. This step aims to limit the damage and prevent further unauthorized access or data loss. Containment involves isolating affected systems, blocking malicious IP addresses, disconnecting compromised devices from the network, or changing credentials. It's crucial to act swiftly to minimize the impact of the breach and prevent its spread to other parts of the organization's infrastructure.

Question 3

During the containment phase of Incident Response, what is the primary objective?

Prevent the incident from causing further damage Document the incident response process Restore affected systems back to normal operations Analyze the cause of the incident

Correct Answer: Prevent the incident from causing further damage

The primary objective of the containment phase is to prevent the incident from causing further damage, stopping it from spreading, and securing affected systems.
