I look after the computers for my employer. We are a small services company that bases staff at clients sites. As part of this we have a laptop available for our staff's use, mainly for email and a few work related websites. Recently its come to our attention that one of our staff at one site is using the private browsing feature of IE8 and Chrome. While we have a Computer Use Policy without evidence of what sites they are visiting it's limiting what we can do about it. I'd like some suggestions on ways to restrict/monitor the internet use. I do not have access to the router or network equipment and cannot install a firewall/proxy on the network, it is not our network.

One method I am looking at implementing is using OpenDNS on the machine and blocking most categories that are not work related as well as putting in a custom blacklist/whitelist. This would also allow for using OpenDNS's log feature. This is easy to circumvent though and makes life that much more difficult for the site manager who is trusted to use the machine for other uses.

Can anyone suggest a lite application or another method for restricting the use of the internet? I have been looking into disabling the private browsing features, with IE8 this is possible but with Chrome currently it is not. If its a software method I don't want to install an intensive application, I'd rather something simple that uses few resources.

Any ideas would be appreciated. For the time being I'll be implementing OpenDNS until a better option makes its self known :-)

We use Webmarshal across most of our offices, works well - just block HTTP/HTTPS traffic from being allowed through your firewall/router except from the server running Webmarshal, and youre done :) Noone can get out except through WM. But it does cost a bit....

Another solution someone on GZ suggested a few weeks back, was Untangle - Ive been playing with it and seems pretty good for filtering etc, I am using the free version for testing with, not sure what the license says about company use as they do have some other packages with fees...suspect a company use version would require a fee.

Holdenhsv2010: Download a Program called "{spam removed}" it will cost you money but it will allow you to remotely monitor the laptop. it has a feature called view only so you can see what they are doing and if they are doing something they aren't allowed to do you can log them off or pay them a visit. also you can take screen shots for evidence. The program will also run in hidden mode on the laptop so they will have no idear you are playing big brother.

And then you might get a lawsuit for privacy breach...

First you have to put policies for using the Internet in place. Make everyone sign it. Make it clear in the policy what is allowed and not. This way they can't claim they didn't know something they did was wrong.

Next use of the proxy solutions, make sure the only outbound traffic allowed is the one coming from the proxy.

Then use OpenDNS as the DNS provider for that proxy. This will give you an automatic filtering system based on categories that will automatically apply to the proxy.

Cheers everybody, some good suggestions. I'm hesitant to use any sort of hidden remote monitoring software for very much the reason freitasm mentioned, plus I'd rather not have to monitor in realtime. An internet policy is a great idea, I didn't think of that and will work on adding one this week. K9 is a good option to look into, cheers CYaBro. I don't have the means to put anything on the network other than our laptop xpd, its our clients network. Uninstalling Chrome is also not an option as I like it and want to use it :D
