What improvements does a VLAN offer for network security?
Logically separates network segments
Physically restricts unauthorized devices from network access
Allows for session dropping in the event of an anomaly detection
Provides layer 4 filtering (TCP/UDP)
A Virtual Local Area Network (VLAN) provides a logical or virtual way to separate areas of a network. This means devices can physically share the same network infrastructure (e.g. using a common switch) but remain separated from each other on the network.
