What primary benefit does micro-segmentation provide?

1. Enhanced physical security

2. Reduced dependency on firewalls

3. Improved network visibility

4. Increased control over east-west traffic

The correct answer is: Increased control over east-west traffic

Micro-segmentation primarily enhances security by providing increased control over east-west traffic within a network. In traditional network architectures, security measures are often focused on perimeter defenses, which can leave internal communications vulnerable to threats. By employing micro-segmentation, organizations can create distinct security zones within their network, allowing for more granular control over how data flows between different segments. This means that even if a malicious actor gains access to one segment of the network, they face significant challenges to move laterally or access other segments. By limiting communication paths and enforcing strict access policies between these segments, organizations can better protect sensitive data and critical systems, ultimately reducing the attack surface. This approach contrasts with the other choices. Enhanced physical security pertains to securing physical assets rather than managing network traffic. Reduced dependency on firewalls overlooks the importance of layered security measures—firewalls still play a crucial role even in micro-segmented environments. Improved network visibility is a beneficial outcome but is a broader concept that doesn't specifically illustrate the core advantage of micro-segmentation. Thus, the primary benefit of micro-segmentation is its capability to provide fine-tuned control over east-west traffic, strengthening overall network security.
