Hi Dan,
You are correct we are not able to enforce client policies without an agent=
, as student machines are not university owned.
I'll start with guest access. I am building into the system a mechanism to=
'mint' guest accounts which can be used to register devices on the network=
. As a guest you are segregated into a private VLAN which allows internet =
access, but no on-campus resources. There are a few unanswered questions a=
t this point, of which I suspect that printing will be the most important. =
We have a web-print capability here, so I do not expect that to be an issu=
e. As a guest, I don't expect you to need access to my file shares, so I a=
m perfectly fine with providing you with Internet access and nothing more.
Next, remediation. In the NAC/Bradford model, the remediation network has =
access to anti-virus updates, windows updates, etc. In my model, this netw=
ork does not exist in the same sense because I do not enforce client polici=
es. No antivirus policies to enforce =3D no remediation necessary.
So, when you ask about remediation, you are really asking about AUP violati=
ons and "strange network traffic", i.e. malware. This is where the traditi=
onal remediation network would be helpful, and the latest software on our P=
acketLogic may be able to help me there. I haven't done any proof-of-conce=
pts on this yet, but I am relatively unconcerned with this. Let me explain=
why.
In the event of a AUP violation, such as a complaint of copyright infringem=
ent, we can "jail" a machine in a blackhole VLAN, assuming that is what you=
desire to do. My last school had an automated graduated response system w=
here you were cut off of the network for 1 or 2 weeks, followed by a meetin=
g with student affairs. SMU does not currently have such a policy in place=
(working on it). We don't get many copyright complaints.
In the event of virus infection, if we detect strange traffic we can also "=
jail" the user. We can present a helpful message to them and instruct them=
to approach our helpdesk for assistance resolving the issue, if necessary.=
This is the most difficult thing to be comfortable with, but it isn't as =
scary in practice as it sounds on paper. If a student called and told us t=
hat they had cleaned the infection (we provided local caches of several cur=
rent antivirus products, and an 'automated cleaning script' which would all=
ow them to run with zero user interaction), we would release them. Occasio=
nally, they would still be infected, so we would require their computer to =
be brought to us, or we would schedule a housecall and clean it up on-site.
This sounds like a heavy support load, but it really wasn't too bad. At my=
last school, I was responsible for the end-user support for the ResNet sys=
tem of approximately 2000 students. I was half-time, and we had a full-tim=
e administrator. There was one other student who would help with the suppo=
rt when necessary, as well as another member of the professional staff who =
again would help as time was available. So our support load was approximat=
ely 2.25 FTE. Then take into account that our netadmin had other duties, a=
nd wasn't available for virus cleaning, so our user-facing support was real=
ly closer to 1.25 FTE. At SMU, we are a much smaller school, and while we h=
ave a smaller IT shop, we also do not have the distinction of "self-funded"=
IT (like I was) vs. "state-funded" IT, so we can pool our work-study stude=
nts and other desktop support staff. Our campus is also much, much smaller=
, so I am not concerned about the support load, and if you have a handful o=
f talented student workers, I suspect that you need not be concerned about =
it either.
Of course, for this to work, you have to be able to identify "strange traff=
ic" and take action. I haven't gotten that far in my implementation yet, b=
ut there are numerous ways to go about generating data for analysis. I sus=
pect that Perl will be the key to making this part of the system work.

Subject: Re: NAC solution removal
While I do not disagree that the whole NAC solution can degrade the Interne=
t experience and does add some administrative overhead, what are you doing =
for remediation in regards to your clients? In our network we can enforce s=
ystem patches, anti-virus is updated since these systems are university own=
ed.
However when it comes to our students we do not have that ability as we do =
not have ownership. Instead we require installation of an agent that ensure=
s the students are complying to the AUP and keeping their own systems up to=
date. Should a system fall out of compliance after a set period of time th=
e user loses Internet access.
Similarly how to do you protect against guest access, especially if a guest=
is bringing a worm, virus, malware, etc?
In today's budget conscience world I can certainly see removal of money guz=
zling equipment if you have a cheaper means to maintain the same or close t=
o the same level of protection for your network and I too would love to sav=
e money where possible!
Thanks!

Subject: Re: NAC solution removal
My last institution didn't employ a NAC, but instead used a homebrew client=
registration system to help keep order. MAC addresses were registered int=
o a database, and VMPS was used to assign machines to the correct VLAN when=
they connected. Machines showing 'interesting' behavior or subject to a p=
olicy sanction were either assigned to a jail VLAN or ignored completely (s=
witchport can be disabled remotely via VMPS as well).
At SMU, we are in the process of removing our Bradford NAC and replacing it=
with a system similar to the one described above. Because we are not a ci=
sco shop (and VMPS is deprecated) we are employing 802.1x MAC address authe=
ntication and dynamic VLAN assignment via RADIUS. The system is designed t=
o be a full-campus solution, but could be deployed to ResNet only if desire=
d.
At this time, all proof-of-concept and integration tests have been complete=
d, and I am in the process of finishing the management scripts and registra=
tion user interface. Notes and code can be made available to any intereste=
d parties.
As far as why we are doing this, I find the cost of implementing the NAC is=
too much considering what we get out of it. While the 802.1X/RADIUS/DVA s=
olution does not provide me with the same level of control that the NAC doe=
s, it also doesn't require the client software that seems to degrade our us=
er experience so much. I want to be able to identify a machine on a networ=
k as belonging to a particular student, and take enforcement measures if ne=
cessary. Since this provides me with a big "Internet kill switch" on each =
machine, it works well enough for my purposes.

libri","sans-serif";color:#1F497D">My last institution didn&=
#8217;t employ a NAC, but instead used a homebrew client registration syste=
m to help keep order. MAC addresses were registered into a database,
and VMPS was used to assign machines to the correct VLAN when they connect=
ed. Machines showing ‘interesting’ behavior or subject to=
a policy sanction were either assigned to a jail VLAN or ignored completel=
y (switchport can be disabled remotely via VMPS as
well).<o:p></o:p></span></p>

<p class=3D"MsoNormal"><span style=3D"font-size:11.0pt;font-family:"Ca=
libri","sans-serif";color:#1F497D">At SMU, we are in the pro=
cess of removing our Bradford NAC and replacing it with a system similar to=
the one described above. Because we are not a cisco shop
(and VMPS is deprecated) we are employing 802.1x MAC address authenticatio=
n and dynamic VLAN assignment via RADIUS. The system is designed to b=
e a full-campus solution, but could be deployed to ResNet only if desired.<=

<p class=3D"MsoNormal"><span style=3D"font-size:11.0pt;font-family:"Ca=
libri","sans-serif";color:#1F497D">At this time, all proof-o=
f-concept and integration tests have been completed, and I am in the proces=

interface. Notes and code can be made available to any interested pa=

<p class=3D"MsoNormal"><span style=3D"font-size:11.0pt;font-family:"Ca=
libri","sans-serif";color:#1F497D">As far as why we are doin=
g this, I find the cost of implementing the NAC is too much considering wha=
t we get out of it. While the 802.1X/RADIUS/DVA solution
does not provide me with the same level of control that the NAC does, it a=
lso doesn’t require the client software that seems to degrade our use=
r experience so much. I want to be able to identify a machine on a ne=
twork as belonging to a particular student,
and take enforcement measures if necessary. Since this provides me w=
ith a big “Internet kill switch” on each machine, it works well=
enough for my purposes.<o:p></o:p></span></p>
