Incident Response Management

5 minutes 5 Questions

Incident response management is the process of planning for, detecting, analyzing, containing, eradicating, and recovering from security incidents, as well as the subsequent actions to prevent recurrence. A well-defined incident response plan (IRP) should include roles and responsibilities for incident response team members, communication protocols, escalation procedures, and checklists for handling various types of incidents. Timely and effective incident response is crucial to mitigating the potential damage from security incidents, preserving evidence for investigations, and ensuring business continuity. Regularly testing and updating the IRP, conducting lessons-learned exercises, and sharing information about incidents with stakeholders helps organizations continually improve their incident response capabilities and build resilience against future attacks.

Guide: Incident Response Management

Incident Response Management is a strategic approach to handle and manage the aftermath of a security breach or attack, also referred to as an incident. The goal is to efficiently manage the situation in a way that limits damage and reduces recovery time and costs.

Why is it Important?
Incident Response Management is crucial in managing the effectiveness of security controls. It plays a significant role in mitigating risks and preventing further escalation of security incidents. A well-planned incident response can significantly reduce any business impact of security incidents.

How does it Work?
Incident Response Management usually involves 5 stages: preparation, identification, containment, eradication, and recovery. In each phase, appropriate measures are taken to handle the situation effectively.

Question 1

While conducting an incident response process, you discover evidence of violation of company security policies. Which of these actions would help maintain the chain of custody of this evidence?

Destroy the evidence to prevent further data breaches Document all handling, storage, and transfers of the evidence Send a copy of the evidence to the affected employee's manager Publicize the evidence to the entire organization

Correct Answer: Document all handling, storage, and transfers of the evidence

Maintaining a chain of custody requires documenting all evidence handling, including storage and transfer. This preserves its integrity and ensures legal admissibility. The other responses may compromise the evidence or violate privacy or legal obligations.

Question 2

You have discovered suspicious network traffic originating from a single user. The user's credentials have been compromised. What is the most appropriate step in the incident response?

Monitor the activity without intervention Disable the compromised account and assess the extent of the breach Immediately terminate the user's employment Notify all employees of the breach via a company-wide email

Correct Answer: Disable the compromised account and assess the extent of the breach

Disabling the compromised account and conducting a thorough assessment of the breach is the most appropriate response. Monitoring the activity can lead to further damage and termination of employment is drastic. The other options do not directly address the situation.

Question 3

A security analyst receives a report of a data breach from an external source. What should be their first action?

Notify the Incident Response Team to validate the report Conduct a pen-test on the system Ignore the report Notify the media

Correct Answer: Notify the Incident Response Team to validate the report

When receiving a data breach report, the security analyst should notify the Incident Response Team first. The team will then validate the report and determine the necessary actions. Ignoring the report or making premature notifications to media or employees can cause panic or misinformation. Conducting a pen-test or revoking access may not directly address the issue.
