How can VLANs Provide Network Security?

A computer network is used by almost all businesses, large and small. By using this network, most of our conversations, reports, and tasks are completed. Although a network is already given, many firms do not fully utilize the most current technological capabilities available. There are various advantages to using a virtual local area network (VLAN). With a VLAN, you may save IT expenditures while improving network security, performance, and administration.

What is VLAN?

If you want to know about a virtual private network (VLAN), it is beneficial first to comprehend a local area network (LAN). It is a set of computers linked together in a specific location (like an office). However, the two may share many of the same features as a LAN; VLANs enable computers and other devices to connect as if they were all part of the same broadcast domain. 

Essentially, a VLAN serves as a mini network in a LAN. Managed LAN Services allow you to divide a massive network into smaller ones, which is quite helpful in an office network.

How Can VLANS Provide Network Security?

It does not mean that all VLAN-capable managed switches perform equally well in this respect. A switch in a VLAN-enabled network must do much more than just transfer packets across ports. Maintaining proper VLAN operation relies on the core backbone switches. Other than switching packets between VLANs and checking for network loops, one of these switches’ key roles is providing network security depending on the settings they are configured to do. Packets are prioritized by these switches depending on their origin and destination.

Most IT managers prefer to connect servers directly to the core-backbone switches rather than using access switches on their edge devices, such as personal computers, network peripherals, and even servers, on occasion. You cannot avoid complications if the core backbone switches and the edge switches are incompatible, and that’s how VLANs can provide network security

Controllers with VLAN Connectivity

Access and trunk connections are two of the most prevalent types of connectivity in a VLAN. Very often, you’ll notice Access Links on a VLAN-capable switch. Network hosts utilize the switch’s Access Links to connect to the network. Standard connectors on each button may be used for these connections. A trunk link connects two VLAN-capable switches. 

A Trunk Link, on the one hand, is permanently set to carry data from all available VLANs. On the other hand, an Access Link can only access a single VLAN at a time.

VLAN Strategic Approaches

While many administrators and IT managers are well-versed in VLAN technology and principles, this does not necessarily hold for the security of VLAN systems. The basic rule of VLAN security is to keep the network physically secure. 

Any business concerned about the safety of its equipment must have stringent access controls. Data centers with limited access often house core switches, although edge switches are frequently found in open areas.


Multitasking without compromising quality, speed, or network availability is now possible – thanks to virtual local area networks (VLANs). 

A VLAN may significantly minimize administrative burden if fundamental security standards are considered during initial setup and maintenance. It’s easy to overlook the relevance of the data link layer and Wired/Wireless LAN infrastructure consulting.
