When it comes to the modern enterprise, few things are more important than network and identity security. With bad actors lurking around every corner (even inside of an organization itself), maintaining a strong, secure network along with keeping credentials safe is of utmost importance to the IT admin. Several network securing tools and techniques are being employed by IT admins today, especially during the global pandemic, but one that has been a foundational approach for many years is dynamic VLAN assignment. Since IT admins are dramatically stepping up the security of their IT environments, some are asking: what is dynamic VLAN assignment and how can it help secure the network?<\/p>\n\n\n\n

Network Security with Dynamic VLAN Assignment<\/h2>\n\n\n\n

The simple answer is that dynamic VLAN assignment (or VLAN steering<\/a> as it is sometimes called) is an excellent technique used to build on the underlying core strategy to control network access. VLAN assignments build on the use of RADIUS to control access to the network. <\/p>\n\n\n\n

Via RADIUS integration, a WiFi access point (WAP) requires not only an SSID and passphrase, but a user\u2019s unique set of credentials to access the network. Once a user has passed credentials through to the WAP to the RADIUS server and directory service, the RADIUS server will reply to the WAP that the user has been authenticated and inform what VLAN they are assigned to.<\/p>\n\n\n\n

IT admins configure the system to identify which users and\/or groups are assigned to which VLAN. Those VLANs can be set up on the WiFi network for any number of reasons including security and compliance. By segmenting users and authenticating them with their unique credentials, IT admins can increase security significantly. This approach helps separate out critical areas of the network, and can be especially helpful in compliance situations where, for example, the cardholder data environment (CDE) can be separated from the rest of the network making PCI Compliance far easier.<\/p>\n\n\n\n

Challenges with Dynamic VLAN Assignments<\/h2>\n\n\n\n

The challenge with this approach is the overhead for IT admins. Traditionally, to implement dynamic VLAN assignments would require a great deal of infrastructure, configuration, and administration. For starters, IT organizations would need to set up their own FreeRADIUS server and connect that instance to the wireless access points and the identity provider (IdP), often, Microsoft\u00ae<\/sup> Active Directory\u00ae<\/sup><\/a>.<\/p>\n\n\n\n

In many networks, the IT group would also need to configure endpoints with supplicants so that they could talk to the RADIUS server over the proper protocols. All of this ended up being a significant disincentive for IT admins, and that is why many WiFi networks are secured simply with an SSID and passphrase.<\/p>\n\n\n\n

With the introduction of modern cloud RADIUS solutions, however, IT admins can virtually outsource the entire process for RADIUS authentication to WiFi and dynamic VLAN assignments. This Cloud RADIUS<\/a> offering doesn\u2019t focus on RADIUS only, but also acts as the identity management source of truth that can replace an on-prem Active Directory instance. It is available from the JumpCloud Directory Platform<\/a>.<\/p>\n\n\n\n

Cloud RADIUS and More<\/h2>\n\n\n\n

JumpCloud Directory Platform is everything a directory service was, and reimagines it for the cloud era. This includes endpoint management<\/a>, identity and access management, single sign-on, multi-factor authentication, and network authentication tools such as Cloud RADIUS. Relatively new to the JumpCloud Suite is dynamic VLAN assignment<\/a> functionality, so network administrators can better authorize their users\u2019 access to crucial network resources. This feature just adds one more log to the bright flame of this cloud directory.<\/p>\n\n\n\n
