A. Increases overall network speed
B. Prevents all cyberattacks
C. Reduces the impact of security breaches by limiting lateral movement
D. Eliminates the need for antivirus software
E. Makes all network traffic invisible to attackers
Answer
C. Reduces the impact of security breaches by limiting lateral movement
Explanation
Network segmentation isolates critical systems to prevent attackers from easily moving through the network after breaching one part.
The primary benefit of network segmentation is that it reduces the impact of security breaches by limiting lateral movement within the network.
Network segmentation divides a larger network into smaller, isolated segments or zones, each with its own access controls and security policies.
If an attacker breaches one segment, segmentation prevents them from easily moving (lateral movement) to other parts of the network, containing the threat and minimizing potential damage.
This containment, often called limiting the “blast radius,” ensures that critical assets and sensitive data in other segments remain protected, even if one area is compromised.
Segmentation also enables more granular access control, supports regulatory compliance, and can improve network performance, but its most significant security advantage is restricting attacker movement after an initial breach.
This approach aligns with modern security strategies, such as Zero Trust, which assume breaches are inevitable and focus on minimizing their impact through isolation and strict access controls.
Network segmentation isolates critical systems, preventing attackers from easily moving through the network after breaching one part, and is a foundational strategy for modern cybersecurity defense.
