Guide: Network Segmentation & Microsegmentation

What is Network Segmentation and Microsegmentation?
Network segmentation is the practice of dividing a computer network into subnetworks, each being a network segment or network layer. Microsegmentation, on the other hand, is the process of breaking down a network into smaller parts - a more granular approach than network segmentation. This enables better control and security within a network.

Why are they important?
They are important because they enhance network performance, improve network security, prevent network congestion and reduce the impact of network failures. Network segmentation and microsegmentation partition the network to confine network traffic to its own segment, which enhances control over the commitments of each segment of the network.

How does it work?
Network segmentation works by segregating data packets through the use of different physical or logical connectors such as switches, routers or bridges while microsegmentation involves deep packet inspection and can be done via software or firewall configurations.

Exam Tips: Answering Questions on Network Segmentation and Microsegmentation
There are two keys to answering these questions correctly: understanding the concepts and applying the principles. Make sure you understand the definitions of both techniques, their advantages and characteristics, and real-life application scenarios. By being proficient in these areas, you're likely to answer exam questions on network segmentation and microsegmentation successfully.

Remember to highlight the importance of improving network security and performance as one of the main benefits. Additionally, illustrating your understanding of how network segmentation works physically and logically can be a winning strategy in an exam.
