Another Flash 0-day in the wild. Anyone blocking Flash yet? Web Ads? Strategies?
I have 3 questions for you fellow in-the-trenches proxy admins. I'd be delighted with any input on any or all of them that you can share from your experience.
Has anyone successfully transitioned to a url or site whitelist approach for allowing Flash? I know some folks do this with Java with sleep-assuring success.
On a semi-related note, how many of ya are able to block Web Ads category and avoid the pitchforks and user screaming?
On a wing and a prayer note, is there a single administrator who has successfully blocked Uncategorized and not been neutered by the users before noon on Monday? The best I've achieved in an environment is uncategorized executables from med/high risk ip's or known unfriendly TLD's. (This "block all uncategorized" advice strongly advocated by a couple of incident responders from a rather well known vulnerability scanning vendor giving a talk at a local security conference last week ... which smacked of "I've never actually attempted any of the advice I'm espousing," but I'd like to verify that with you fellow proxy admins)

dcaffrey, Boy I'd love to do that too. How's that been going?
I've long assumed that it'd make my life an impenetrable hell given the rather large universe of uncategorized that seems to be relatively important to a lot of increasingly complex sites. Has the trustedsource universe of Uncategorized actually gotten manageably small? How many users are you supporting? How many sites are you having to submit daily?
