What are the best practices for network segmentation?

Network segmentation involves dividing a network into smaller parts to improve security and performance. Best practices include defining clear segmentation goals, using VLANs, implementing access controls, and regularly reviewing and updating your segmentation strategy.

How do VLANs help in network segmentation?

VLANs, or Virtual Local Area Networks, allow you to create distinct broadcast domains within a single physical network. This helps isolate traffic, enhances security, and improves performance by reducing congestion.

What tools can I use for network segmentation?

Common tools for network segmentation include firewalls, routers with VLAN support, and network monitoring software. Solutions like Cisco ACI and VMware NSX also provide advanced segmentation capabilities.

How often should I review my network segmentation strategy?

It's recommended to review your network segmentation strategy at least annually or whenever there are significant changes in your network infrastructure or security requirements.
