As IT admins work to increase the overall security stance of their network, one feature gaining popularity is dynamic VLAN (virtual local area network) assignment. Traditionally done with wired networks through switches, IT organizations are leveraging this capability for their WiFi networks and access points through a cloud RADIUS implementation. Let鈥檚 explore dynamic VLAN assignment with cloud RADIUS.
What is Dynamic VLAN Assignment?
The concept of dynamic VLAN assignment (aka VLAN steering or tagging) is quite simple. A VLAN is a segment of the whole of the network, which only provides access to a selection of network resources. Based on a user鈥檚 identity, the WiFi access point (WAP) is told which VLAN the user should be placed in. This process can step up security, help with compliance, and potentially balance load and quality of service. Regardless of the reason or requirement, the process is the same.
A user or group of users are assigned to a specific VLAN through . These attributes are placed into the . When a user attempts to authenticate to the network, there are multiple levels of assessment. The first is whether the user鈥檚 credentials are correct鈥攖his assessment is done via the on-board directory service in the case of RADIUS-as-a-Service. Then, assuming a successful authentication, the user鈥檚 identity and group information is used to lookup which VLAN assignment they have. As part of the RADIUS server鈥檚 reply to the wireless access point, the VLAN assignment is passed along. The WAP uses that information to then assign the user to the specific VLAN.
The Value of VLAN Assignment
The process of implementing VLAN assignment is tedious but straightforward, although the value it brings significantly outweighs the undertaking. IT organizations can leverage dynamic VLAN steering to help support compliance activities and security programs. By excluding users from sensitive resources they do not need to access, the attack vectors sourced from compromised credentials are cut down severely.
Of course, many organizations don鈥檛 take advantage of VLAN assignment due to the process of implementing it network-wide. While it isn鈥檛 necessarily difficult, not every organization has the proper network and identity management tools to implement VLAN assignments effectively. After all, in order to control which resources are tied to which VLANs, each user鈥檚 core identity in the directory service needs to be linked directly to the WAP. This can be simply done through leveraging 黑料海角91入口庐 Directory-as-a-Service庐.
VLAN Assignment with 黑料海角91入口庐
With 黑料海角91入口鈥檚 Directory-as-a-Service platform, the entire process of implementing VLAN assignment is made easier. 黑料海角91入口鈥檚 RADIUS-as-a-Service includes the ability to assign reply attributes, has an onboard directory service, and doesn鈥檛 require IT admins to configure endpoints with the correct supplicants. Simply point the WAP to the virtual RADIUS server, and your end users鈥� core credentials are leveraged for their access to the network.
