Could Snort or any NIDS for that matter, tapped in at the last cable between the users and firewall be substituted for a proxy? I too am having this problem. All of our users are allowed to use our training room PCs to surf the web while on lunch or break. However they are all configured with roaming profiles which makes it near impossible to determine weather or not the cookies/history were created while the user was on a training PC or their production machine.

The best best answer is a proxy server that logs all access and an email server that keeps a record of all mail.

If any of you have defined (or mostly defined) procedures for investigation WFA, please send them my way. So far, we do the normal: 1. extract browser history 2. extract browser cache 3. extract all known information formats (pictures, word processing files, mp3s, wavs, etc) 4. extract cookies 5. extract activity as captured by NIDS Anything I need to add here? Anyone got any good (sanitized) final WFA reports? I'd also like to see if our format needs updating. I understand that a lot of this is based on company HR policy, but I'd like to see industry best practices, if I could. Thanks, JJ --------------------- J. J.
