Incident Follow-Up

5 minutes 5 Questions

Incident follow-up is a critical, yet often overlooked, part of the incident response process. This step consists of analyzing the root causes and contributing factors of the security incident to identify areas for improvement and prevent future incidents. During follow-up, lessons learned from the incident should be documented and shared with relevant stakeholders, processes and procedures should be revised as needed, and staff should be retrained or re-educated where necessary. A comprehensive follow-up process allows an organization to strengthen its security posture and resilience in the face of future threats.

Concept Guide: Incident Follow-Up in CompTIA Security+ Exam

What is Incident Follow-Up?
Incident Follow-Up is an essential stage in Incident Response and Forensics, which involves evaluating and documenting the incident response process for potential improvements. This process typically includes an incident report, a post-mortem (or lessons learned) meeting, and necessary changes for preventing recurrence. It helps in improving the organization's response to future incidents and mitigating potential risks.

Why is it important?
Incident Follow-Up is crucial as it determines the effectiveness of an organization's incident response strategy. It aims to convert prior incidents to lessons learned, prevents the repetition of the same mistakes, and strengthens defenses against future cybersecurity threats.

How does it work?
The process commences with the documentation of the incident, analysis of the response strategy and its effectiveness, identification of loopholes, and recommended measures for improvement. The outcomes feed into policy updates, process refinement, and staff training - thereby improving the overall security framework.

Question 1

A company has recently experienced a data breach. An investigation concludes that a malicious insider gained unauthorized access to sensitive customer data. Which of the following controls should be put in place to mitigate the risk of similar incidents occurring in the future?

Implement the principle of least privilege Install anti-malware software Disable all external connections Enable honeypots

Correct Answer: Implement the principle of least privilege

Implementing the principle of least privilege ensures that users only have access to the resources required for their job duties, minimizing the risk of insiders misusing or accessing unauthorized data.

Question 2

A security analyst discovered that an attacker accessed an administrator account and remotely modified server configurations. Which of the following actions should the company take in response to this incident?

Upgrade all server hardware Disconnect all user access to servers Reset all administrator account credentials Build a new network infrastructure

Correct Answer: Reset all administrator account credentials

Resetting all administrator account credentials helps to ensure that the attacker no longer possesses valid credentials, preventing further unauthorized access to the servers and systems.

Question 3

A company is conducting security audit after a successful phishing attack. The IT team discovers that multiple employees re-use the same weak passwords on multiple platforms. What should the company do to prevent the future occurrence of such a problem?

Implement password complexity and management guidelines Disconnect employee internet access Limit the number of login attempts Force employees to use biometric authentication

Correct Answer: Implement password complexity and management guidelines

Password complexity and management guidelines will educate employees on the importance of using strong and unique passwords, minimizing the risk of successful cyberattacks in future.
