CompTIA CySA+ (CS0-003) — Question 303

A junior security analyst opened ports on the company’s firewall, and the company experienced a data breach. Which of the following most likely caused the data breach?

Answer options

• A. Environmental hacktivist
• B. Accidental insider threat
• C. Nation-state
• D. Organized crime group

Correct answer: B

Explanation

The most likely cause of the data breach is an accidental insider threat, as the junior analyst may not have fully understood the implications of opening the ports. In contrast, environmental hacktivists, nation-states, and organized crime groups typically engage in more targeted or sophisticated attacks that would not result from a simple misconfiguration by an employee.
