Hi all.  I am new to the list and from checking out the archives I see that this can be a great resource.   I am currently on staff at Wilfrid Laurier University in Waterloo Ontario in the IT Operations group.
 
 We have network that has fairly good identity awareness in that the network access tables does retrieve information such as mac addresses, ip numbers etc and these can be extracted by router/switch to identify which building and even which floor devices reside.  We also utilize Zenworks 10.3.3 Configuration Manager to deploy software packages, policies and so on.  We are currently building a new IDM system for account creation, user profiles and maintenance.  My question is this.  Is there a way for all these technologies to work together?  For example,  if a user's computer is spewing out a broadcast storm and we know it's mac address or ip address, currently we have a fairly good idea on which building and possibly which floor it resides in but after that its a matter of finding the computer.  It would be nice if there was a way to identify the computer and it's owner's profile (name and room number) via the mac or ip address.  I'm sure that something exists.  Can someone point me in the right direction.
 
Thank you.

Hi Rene,

There are several potential approaches to associate userId with IP address and MAC address. The most complete, and probably the hardest, is to implement 802.1x across both wireless and wireline network access, ie, require login to gain access to the network itself. Perhaps start with wireless since 802.1x secures the radio link and prepares your institution to participate in eduRoam, great capabilities to have in any case.

Short of that, comprehensive use of DHCP for user access workstations can be leveraged to know which MAC address is using which IP address at what times. Depending on the DHCP server implementation you operate, it may also be possible for that service to correlate userId and MAC address, ie, as a consequence of running an application to register end nodes for DHCP service. Putting those two correlations together gives you (userId, IP, MAC, time).

Other approaches I'm aware of rely on an agent running on users' computers, as is typically done in a "Network Access Control" implementation, eg, Cisco NAC, Juniper UAC, or Bradford Campus Manager (or ZenWorks, I believe). Those agents scan the user's computer to ensure that security requirements are met and can also report userId, IP, and MAC to a server, among other functions.

Finally, a more patchwork and home-grown approach can be undertaken by automated analysis of authentication logs for popular services and correlating with information gathered from network gear or DHCP service.

I haven't operated a Zen environment for many years, but if that is already deployed, I'd look into whether or not those agents can supply the info you seek. That might be the smallest step to get what you want from where you already are.

You may wish to look into this.


Basically for a computer to get on our network, faculty, staff, and students launch a web browser, and if their computer is not registered they are directed to a registration page.  They login with their credentials, their IP address is shown and they click register my device.

Our IT professionals across campus use open ipam to register and manage large groups of computers.  Computers are registered for 365 days, at which point they get an email telling them they need to renew their registration.  This has kept our IP name space managed.
