An Incident Response Team (IRT) is a group of skilled professionals responsible for the identification, management, and resolution of cybersecurity incidents. The IRT is an essential component of an organization's incident response strategy and plays a critical role in handling incidents effectively and minimizing impacts. The IRT is typically composed of professionals from various disciplines, such as network security, system administration, legal counsel, and public relations, to ensure all aspects of an incident are addressed. A functional IRT will conduct regular exercises to refine skills, review response procedures, and ensure preparedness for future incidents.

Question 1

A member of the Incident Response Team, you received a report of suspicious activity on a server hosting sensitive data. What should be your first step to investigate?

Notify all employees about the suspicious activity Review logs and access control lists of the affected server Disconnect the server from the network before investigation Wipe the server to remove any potential threat

Correct Answer: Review logs and access control lists of the affected server

The correct answer is 'Review logs and access control lists of the affected server' to gather information and assess the situation. Other options, such as notifying all employees, disconnecting the server, wiping it, upgrading hardware, or contacting law enforcement, can disrupt operations, create panic, or prematurely involve authorities without understanding the scope of the issue.

Perform a full-scale forensic analysis Contact the press and provide details of the breach Contain the breach and minimize damage Notify law enforcement

Correct Answer: Contain the breach and minimize damage

When responding to a security breach, the first priority is to contain the breach and minimize the damage, followed by investigation, eradication, recovery, and incident documentation. Other answers are not prioritized as the first step.

Question 3

Send an email to all employees requesting they click a link to confirm their credentials Ensure compromised systems are isolated and secured Hold a company-wide meeting to discuss the event Implement password complexity requirements

Correct Answer: Ensure compromised systems are isolated and secured

Before notifying employees, the team should ensure that compromised systems are isolated and secured to minimize potential damage. Other actions listed may be taken later in the response process and/or may not be directly related to addressing the phishing attack.
