Re: Blocked URL Categories

We block CnC, phishing and malware as well.  We also block P2P but that is
in our AUP policy and has been for 13 years now.

On the occasion we get a complaint we run it by our ISO and get the okay to
whitelist the URL and that is maybe twice per month.

hacking TTP.



You get into 1st amendment arena if you decide to block others. If any
illegal activity is happening, it’s likely occurring over encrypted channel
or TOR. Everything else can be justified for research or educational
purposes. If you blocked those other categories, it would be a burden to
manage and process exception requests.



Unless there’s a plausible cause, how do you show they’re using it for
illegal activity? You’d have to set up some kind of behavioral based
monitoring.



Occasionally, sites get miscatorgorized as malware. Then I’ll have to look
into it. Reputation databases are pretty helpful with that.

Good afternoon,



We are a public institution in Maryland. We are being questioned by our
state auditors as to why we permit access to the URL categories
abused-drugs, extremism, hacking, and gambling when our AUP states IT
resources are not to be used for illegal activities or "for commercial,
religious, political (including activities supporting the nomination of any
person for political office or attempting to influence the vote in any
election or referendum), solicitation, or profit-making purposes."



Along with academic freedom, the perspective I have been arguing is one to
permit access to the sites. The argument is, just because a student
accesses a gambling website does not mean they are gambling.



So, my questions to the group are:

   - Do you block these URL categories by default?
   - If so, how do you address the request to research in areas that
   might require access to these URLs?
   - How did you convince the auditors it was necessary to allow access
   to these categories?

As always, responses can be addressed directly to me or via the listserv.



Thank you for your input!
