NSE Incident Response & Recovery Procedures

Question 1

What is the first step in the incident response process?

Accepted Answer

Identification

Answer

The incident response process typically begins with identification, where an organization detects and confirms a security incident. This initial phase involves monitoring systems, analyzing alerts, and determining if an actual breach or security event has occurred. Accurate identification is crucial for initiating the subsequent response steps.

Question 2

Which team handles security incidents in an organization?

Accepted Answer

Incident Response Team

Answer

An Incident Response Team (IRT) is a dedicated group within an organization specifically responsible for handling security incidents. Their duties include preparing for, detecting, analyzing, containing, eradicating, and recovering from cybersecurity incidents. The IRT plays a critical role in minimizing the impact of security breaches.

Question 3

What is the purpose of containment in incident response?

Accepted Answer

To limit the impact of the incident

Answer

Containment is a critical phase in incident response where actions are taken to stop the spread of an incident and prevent further damage. This might involve isolating affected systems, disconnecting networks, or blocking malicious activity. The primary goal is to limit the scope and impact of the breach, preventing it from escalating.

Question 4

Which phase involves removing the root cause of an incident?

Accepted Answer

Eradication

Answer

Eradication is the phase in incident response where the root cause of the incident is completely removed from the affected systems and environment. This includes deleting malware, patching vulnerabilities, and removing any unauthorized access points. The goal is to ensure the threat is fully eliminated and cannot re-emerge.

Question 5

What happens during the recovery phase?

Accepted Answer

Restoring affected systems to normal

Answer

The recovery phase focuses on bringing affected systems and services back to full operational status after an incident. This typically involves restoring data from backups, rebuilding compromised systems, and verifying that all vulnerabilities have been addressed. The aim is to ensure business continuity and restore normal operations securely.
