Which type of devices can be utilized to provide network segmentation controls?

Network segmentation is a crucial security measure that helps isolate groups of devices, limiting the potential impact of a security breach and improving overall network performance. The implementation of segmentation can be effectively achieved through specific types of devices known for their capabilities in managing and controlling network traffic.

Switches, routers, and firewalls are integral components in this respect. Switches can create virtual LANs (VLANs) which segment traffic at the data link layer, allowing different segments of a network to communicate only as necessary. Routers can enforce segmentation by controlling traffic between different network segments at the network layer, effectively managing how information flows based on defined rules. Firewalls add an additional layer of security by providing inspection and control points that can restrict or permit traffic based on security policies, further enhancing the segmentation efforts.

Other device categories, such as modems, access points, hubs, printers, scanners, servers, computers, laptops, and tablets do not inherently provide the same level of network traffic management or segmentation capabilities. While they play vital roles in network connectivity and operations, they do not possess the functionality required to enforce the robust segmentation controls that are essential for securing network environments against threats.
