How can segmentation improve security architecture?

Segmentation improves security architecture primarily by limiting access and reducing the attack surface within a network. This is achieved by dividing a network into smaller, manageable segments that can each have different security controls and policies applied to them.

When segmentation is properly implemented, it creates barriers between different portions of a network, making it more difficult for an attacker to move laterally once they gain access to one segment. For example, if a vulnerability exists in one segment, segmentation helps to contain the potential damage, preventing it from impacting other segments. This approach allows for more stringent security measures to be applied to more sensitive areas of the network, enhancing overall security.

Additionally, segmentation can simplify compliance with security regulations, as it allows organizations to isolate sensitive data and apply controls specific to that data. It can also help organizations enforce the principle of least privilege, ensuring users only have access to the data and systems necessary for their roles.

The other choices do not align with how segmentation functions in improving security. For example, increasing the number of access points can introduce additional vulnerabilities rather than enhance security. Likewise, ensuring every user has the same level of access contradicts the fundamental principles of access control, as it can expose sensitive resources to unauthorized users.
