nätsegments

nätsegments is a Swedish term that translates to "network segment" in English. It refers to a smaller, distinct portion of a larger computer network. Network segmentation is a common practice in network design and administration. By dividing a network into smaller segments, administrators can improve performance, security, and manageability. Each segment can be configured with specific policies and access controls, isolating traffic and preventing issues in one segment from impacting others. Common methods for creating network segments include the use of routers, switches, and firewalls. For example, a switch can be configured to create virtual local area networks (VLANs), which effectively divide a physical network into multiple logical segments. This allows for better organization of devices and traffic, such as separating departments or different types of traffic like voice and data. The primary goals of implementing network segmentation are to limit the spread of malware, reduce the attack surface for security threats, and improve overall network efficiency by reducing broadcast domain sizes. It is a fundamental concept in modern network infrastructure.
