Workers on computers and laptops make files of different size and extension. They can send them by mail. I can set up a rule blocking if the file is marked with a particular tag or contains a word from the dictionary. What should I do if an employee will keep a text file into an image, such as bmp or jpeg? Then search the dictionary will not work. If I block all extensions except the doc, then the employee can change the extension of any file in the doc and send it.
Does anyone know the answer to my question?
Is it possible to configure dlpe or NWFP, so I can at least monitor such files?
