![]() What is the easiest way for an attacker to perform VLAN hopping? The most important risk to consider is VLAN hopping. Nevertheless, VLANs do come with some unique security risks that MSPs must keep in mind. When devices are separated into multiple VLANs-often by department-it’s easier to prevent a compromised computer from infecting the entire network. Moreover, a VLAN can also bring added security. Compared to LANs, VLANs have the advantage of reducing network traffic and collisions, as well as being more cost effective. Computers in the VLAN may be separated by bridges, routers, or switches and may be housed in different locations. In contrast, a VLAN is a group of devices on multiple LAN sections that behave as if they are on a single LAN. A Local Area Network (LAN) connects a group of computers in a single physical location to a server using Ethernet cables or wireless internet.
