I need to follow up on a case where a user has been suspected of storing 'inappropriate' images on his/her personal folder on our network. I've done a search on image files and have found no evidence to support the allegation.
WIth this in mind, and with our organisation's policies being tightened in the IT area, I'd like to know if there are utilities that can scan the actual image on the network/mailboxes, rather than looking for filenames called 'smut', etc. If I need to audit or investigate accounts, I'd like to be in a position where 'some' automation is possible.
I've come across www.pixalert.com
but the pricing seems to be a little high. However, I don't know if this is the 'price' to pay for that level of auditing.
Can anyone offer help on this?
