I need to block file uploads to protect confidential data leaving the company network. I am looking for a filewall solution or some kind of montoring software to do this.
I know with MS Forefront TMG can do a man in the middle attack, this could be use to block https uploads.
I was intrested if there is any emplyee monotring software that could do the job of monotring and blocking https/http file uploads.
Ideally a firewall that would limit the amount of uploaded https traffic (to avoid man in the middle attack). For example to 100Kb a min before droping the connection. This solution should allow enough data for page request but not file uploads (ot at least not large amount of data to be uploaded)?
I would also consider a hardware firewall, intead of a software one.
You can try FortiGate devices which supports https,smtps,pop3s and imaps scanning (Man in the middle). Using DLP and custom IPS signatures you can restrict the traffic.
