Re: Web Content Filtering

[Brian Helman <bhelman () SALEMSTATE EDU>]

We have implemented a middle ground on filtering web content – filtering, but not blocking.  Specifically, we take 
advantage of our Palo Alto URL-filtering to notify the surfer that the site they are about to visit may be 
questionable.  They have the option to acknowledge and continue or close that session.  This has cut down on the 
complaints regarding inappropriate/offensive content being displayed in public areas (labs, cafeterias, etc).

My guess is the first thing you will hear is "Academic Freedom" on why no filtering should be allowed.

Filter only known bad traffic such as malware distribution sites and put a web cache in.

Colleagues,
I'm the new CISO for the University of Michigan.  I look forward to meeting you and working with you.  One of my first 
issues is web content filtering.

I've been asked whether any other higher education institutions implement web content filtering and if so what groups 
to you filter for and what kinds of content.  If you wish, I'd also welcome your opinion on how well it works.

This has started with our health system and my guess is that would be our focus if we went forward.  However, one of 
our Trustees has been questioning why we don't filter across the University.  I have to go to an initial meeting Friday 
afternoon, so any info you can give me before then would be much appreciated.

Sincerely,
Don
