Guide: Incident Management and Response

Importance of Incident Management and Response:
Incident Management and Response is one of the core domains of CISSP and a critical component for any organization's cybersecurity program. Its importance lies in its ability to react promptly and manage unexpected or unanticipated security incidents in order to minimize damage, reduce recovery time and costs. It helps organizations to maintain their reputations by demonstrating an ability to deal with security threats effectively.

What is Incident Management and Response:
Incident Management and Response is a process that helps in identification, management, and analysis of security events or incidents within an organization. This includes the creation of an incident response team, development of incident response plans, identification and classification of incidents, and execution of appropriate responses to handle and recover from incidents.

How Incident Management and Response Works:
An effective incident management and response process consist of several stages:
1. Preparation: This step involves planning and preparing for potential incidents2. Identification: Recognizing an event as a security incident3. Containment: Limiting the immediate damage of the incident and stopping its propagation4. Eradication: Removing the cause of the incident and mitigating the vulnerabilities5. Recovery: Ensuring system and operation restoration to normal levels6. Lessons Learned: Debriefing the incident and analyzing for process improvements.

Exam Tips: Answering Questions on Incident Management and Response:
Understanding the concepts and being able to apply them to various scenarios is crucial for exam success. Here are some tips:
- Understand the incident response lifecycle thoroughly, as many exam questions will test this in different scenario contexts- Know the key activities that should be performed at each stage of the response- Ensure knowledge of roles and responsibilities of the incident response team- Be able to identify actions that could possibly escalate the situation vs those that would aid in incident resolution.

Question 1

You are responsible for creating an incident response plan. Recently, a team member left the company and accidentally deleted a critical file before leaving. The file was recovered but took significant time and effort. To avoid similar situations, which type of incident should be added to the plan?

Ransomware Attack Data Leakage Insider Threat Malware Infection

Correct Answer: Insider Threat

Insider Threat incidents cover the potential detection and mitigation of actions performed by a staff member working against the interests of the organization. Other answer choices involve external threats or different types of cybersecurity incidents.

Question 2

You are a security analyst tasked with investigating a spear-phishing incident. Which technique should be used to determine the extent of the breach?

Static code analysis Penetration testing Vulnerability scanning Network traffic analysis

Correct Answer: Network traffic analysis

Network traffic analysis can reveal the flow of data between the affected system and the likely command and control (C&C) infrastructure used by the attacker. Other options listed involve different security methodologies and may not directly help to assess the extent of the breach.

Question 3

Your organization's email gateway detected a suspicious attachment in an employee's email. Your incident response team believes the attachment contained malware. What would be the best way to analyze the attachment?

Attach to an email and send to the security team Open the attachment on the incident response team's workstation for analysis Use a sandbox or isolated system Forward the email to an external email address for analysis

Correct Answer: Use a sandbox or isolated system

Using a sandbox or isolated system minimizes the risk of infecting other systems and allows the incident response team to safely analyze the malware. Other answer choices could potentially put additional systems at risk.
