Network Segmentation
Definition
Network segmentation is a network architecture technique where a larger computer network is divided into smaller,
distinct subnetworks or segments. This division is typically done for several reasons, including improving
performance, security, and manageability.
How it works
Network segmentation divides a computer network into smaller, isolated segments to enhance security and performance.
It restricts communication between segments, limiting the impact of a security breach. Firewalls, VLANs, and routers
enforce segmentation by controlling traffic flow and access. Critical resources, such as servers, are isolated,
reducing the attack surface. Segmentation also optimizes network performance by minimizing broadcast domains and
improving traffic management. This practice improves overall network resilience, protects sensitive data, and
hinders lateral movement for potential attackers.
In robotics
Network segmentation in robotics involves dividing the network infrastructure that supports robotic systems into
separate, smaller subnetworks. This approach is particularly important in robotics due to the critical nature of the
tasks they perform and the potential risks associated with network-based threats.
Considerations
- Strict access control policies are enforced between segments to ensure only authorized devices and personnel
can access certain robotic functions.
- Network segments may have their own intrusion detection systems to identify and mitigate threats within that
segment.
- Continuous monitoring of network traffic within and between segments is crucial to detect any unusual
activities or potential breaches.
