Question

Which type of control has been established when an organization implements a security information and event management (SIEM) system?

A. Preventive
B. Detective
C. Directive
D. Corrective

Answer

B. Detective

Explanation

A SIEM system’s primary function is to detect and alert on suspicious activity within an organization’s IT infrastructure, making it a detective control.

  • Preventive controls aim to avert security incidents before they occur (e.g., firewalls, access controls).
  • Detective controls identify and alert on security incidents after they have happened (e.g., intrusion detection systems, SIEM).
  • Directive controls guide employees towards secure behaviors (e.g., security policies, awareness training).
  • Corrective controls mitigate the impact of security incidents after they occur (e.g., incident response plans, backups).
