Just regular local profiles. Each time they log in they get their own local profile which is a copy of the Default User profile.
Not that I have found, tried a few "tricks" but the results we're always strictly safe.
Generally, it is impossible (or very very difficult) to bypass these safesearch checks. I can think of a few ways you might trick the way we do it by obfuscating your URL so it doesn't get rewritten, but most of these tricks would get you blocked for being a tit in any case.
Some search engines (bing) I can give you more assurance - their images are all served from explicit.bing.com if thay are not safe, so that's nailed on. Some (eg youtube) are less difficult to bypass because of limitations at their end.
In general though it is not something I would worry about too much - hard to bypass, and the profit is generally low :)
So is there a way to enforce strict search with Websense then?
Can you get websense to do arbitrary URL manipulations? If so, you could do it that way.
Moderate *may* be enough for you, I am having difficulty remembering, given that it's sunday morning, and I have reluctantly crawled from my pit after a mate's 30th birthday, and reaffirmed that i can't do hangovers any more.... but i think the difference between strict and moderate isnt all that big. I'll ask around when I get into the office Tuesday, see if i can rustle up some more coherent advice ;)
I am pretty sure it enforces strict, I will check next time I am at work.
Our previous content filter enforced moderate and this was fine, blocking anything dodgy.
Thanks for checking on it, everyone.
Our network administrator says that it only enforces Moderate and that things still show up that the students shouldn't see. If strict could be enforced that'd be great, as the cookie method isn't very foolproof and what is preventing a student from searching on Bing or Yahoo?
Sorry, got hauled off to a meeting in sunny scunny - moderate and strict can both be enforced with the same method.. why is websense playing silly devils?
I have just checked at work, Websense forces the user to use strict for Google Images.
I'm using the Barracuda Web Filter 310 here at the high school I'm at. Works great, has strict safe search as an on/off option out of the box and has always worked. I'd be surprised if Websense of all companies didn't have that built in. Is it something you can ask a Websense support representative about?
@link - yeah, it would seem pretty basic, as functionality goes, but websense is very "corporate" and may not be so geared to education. Sure they must have it though.
