#RADIUS NETWORK MAC ADDRESS SOFTWARE#

Many are speculating that in the near future, Open Directory will not receive regular updates, which can lead to severe security vulnerabilities and an inability to support new macOS versions as well. The drawback here is that it appears Apple is no longer focusing on keeping up Open Directory, choosing instead to hone in on the consumer market they have come to dominate. Admins can integrate their choice of RADIUS server, such as FreeRADIUS, with Open Directory and, after some legwork, integrate RADIUS authentication into their environment.

RADIUS Authentication by Organization Type Mac-Centric Organizationsįor organizations that solely use macOS systems, the average IdP of choice for many years has been Open Directory - a sub-component of macOS Server. With that in mind, let’s examine how RADIUS authentication for Macs works in a handful of hypothetical scenarios.

Regardless, the major issue with RADIUS authentication that admins face is the implementation itself.

Although early Macs required additional supplicant software, most modern Mac systems have native supplicant software baked in that uses the PEAP protocol (which uses a similar process to EAP, detailed above). The supplicant in this case would be on the macOS system. The supplicant is the user/system requesting access to the network via the RADIUS server, and, subsequently, the identity provider. The following graphic details the process for RADIUS authentication on port 802.1x:Ī key aspect to focus on in this scenario, however, is the supplicant and its relationship to the identity provider (not shown in the diagram above). Let’s take a look at the nuts and bolts of RADIUS authentication generally so that we can understand it and apply it for Macs. This process makes it easy to combine multi-factor authentication (MFA) and RADIUS for VPN security as well. Specifically with wireless networks, one of the more popular ways that RADIUS is used is to require users to input their unique set of credentials instead of a shared WPA key, making said authentication tighter than standard WiFi security. The IdP then takes the credentials shared through RADIUS to ensure that a user accessing the network is who they say they are and can be trusted. A RADIUS server works on behalf of a client to authenticate user network access via their credentials stored in an identity provider (IdP). RADIUS stands for the Remote Access Dial In User Service. What is RADIUS?īefore we dive into Mac specifics, let’s look at the RADIUS protocol overall. We will discuss what RADIUS is and how it is used for authentication, as well as how RADIUS is used to authenticate Mac network access. As such, these sysadmins and network engineers are looking for ways to optimize RADIUS authentication for Macs in order to securely connect to WiFi and VPN. Implementing the proper measures can be harder for certain organizations than others, especially those experiencing firsthand the rise of macOS usage in the modern enterprise. Network security is of the utmost importance as the number of reported data breaches continues to rise.
