Question 1

An organization suspects that an advanced persistent threat (APT) has infiltrated their network. What should the Incident Response Team prioritize in their initial response?

Immediately disconnect all systems from the internet. Launch a company-wide phishing awareness campaign. Start the process of recovering lost data. Identify the scope and extent of the compromise.

Correct Answer: Identify the scope and extent of the compromise.

When dealing with an APT, the first priority should be to identify the scope and extent of the compromise to determine the best containment and remediation strategy. Disconnecting systems, increasing awareness, and upgrading security tools should be performed after the initial assessment.

Question 2

A company contracts a security testing firm to assess its client-server application. The firm is asked to simulate an attacker's perspective and identify vulnerabilities from the outside. Which testing methodology is most suitable?

White-box testing Stress testing Gray-box testing Black-box testing

Correct Answer: Black-box testing

Black-box testing simulates the perspective of an external attacker with no prior knowledge of the internal architecture of the application. Therefore, it's the most suitable method to assess client-server applications from the outside.

Question 3

An organization's website was defaced by hackers. Which incident response step should be taken after the containment strategy has been implemented?

Detection Notification Analysis Eradication

Correct Answer: Eradication

Eradication involves determining the root cause of the incident and removing malware or other threats. Detection and Analysis occur before containment, while Notification would depend on the circumstances. Planning and Restoration are later stages of the incident response process.
