Network Segmentation Guide: Using VLANs and ACLs for Zero Trust Enterprise Security
By
HackMoN Ai
Summary
This article provides a comprehensive technical guide on network segmentation using VLANs and ACLs as foundational elements of a Zero Trust security architecture. It covers the evolution from perimeter-based security to micro-segmentation, explains how VLANs create logical network boundaries, and details how ACLs enforce traffic filtering between segments. The piece includes practical configuration examples, best practices for implementation, and a video walkthrough, targeting network engineers looking to bulletproof enterprise networks against lateral movement by attackers.

· 3 pulledIn today's hyper-connected enterprise environment, the perimeter has essentially dissolved.
A single compromised endpoint can provide an attacker with unfettered lateral movement across the entire internal network if segmentation is not properly implemented.
Mastering the synergy between Virtual Local Area Networks (VLANs) and Access Control Lists (ACLs) is no longer just about routing efficiency—it is a foundational pillar of a Zero Trust security architecture.
