How does network segmentation enhance cybersecurity?

1. By restricting all incoming traffic

2. By creating isolated areas to limit lateral movement of attackers

3. By ensuring all data is encrypted

4. By implementing strong password policies

The correct answer is: By creating isolated areas to limit lateral movement of attackers

Network segmentation enhances cybersecurity by creating isolated areas within a network, which limits the lateral movement of attackers. When a network is segmented, an organization divides its IT environment into distinct zones, each with its own security controls and policies. This structure means that if an attacker gains access to one segment of the network, they face obstacles when attempting to move to other segments. For example, sensitive data or critical systems can be placed in separate segments with stricter access controls, minimizing potential exposure. Network segmentation can also help contain threats and reduce the risk of widespread damage by confining them to a single segment, making it easier to identify and remediate breaches. In contrast to the other choices, which have merits in different aspects of cybersecurity, they don't specifically address the unique benefits of segmentation in controlling access and movement within a network. Restricting all incoming traffic might be too broad and could hinder legitimate activities, ensuring all data is encrypted is crucial but not the same as isolating network areas, and strong password policies focus on user access rather than network design. Therefore, creating isolated areas directly correlates with minimizing risk from potential threats.
