Maggie aims to incorporate segmentation into her mitigation strategies. What is the most appropriate explanation of a segmentation approach to network security among the following options?

Segmentation divides networks or systems into smaller units that correspond to specific requirements. Segmentation can be functional, security-focused, or fulfill other objectives. Isolation, which involves removing potentially contaminated systems, is an instance of quarantining. Containment entails employing firewalls and other tools to prevent the infection from spreading while adding security systems to avoid data leakage is an example of implementing a security tool or feature.
