Access Control lists (ACLs), Firewalls, and Intrusion Prevention Systems are examples of

 Definition and Role

Network-based security preventative controls are measures designed to prevent unauthorized

access, attacks, or breaches. Examples include:

Access Control Lists (ACLs): Define rules for network traffic.

Firewalls: Block unauthorized traffic based on predefined rules.

Intrusion Prevention Systems (IPS): Actively block identified threats.

 Comparison of Options

B . Software segmentation controls: Related to application security, not network-level security.

C . Network-based security detective controls: These include tools like IDS, which detect but do not

prevent attacks.

D . User segmentation controls: Focus on user-based access restrictions, not network controls.

 EC-Council Reference

Highlighted in network security strategies as critical tools for perimeter defense and attack

prevention.
