ExeFileBlock

Hi

We have SEP 12.1.4 and we want users should be block copy *.exe files from portabale devices to computer except MS office files (doc, xls, pptp) so we have created SEP application rule to block any file with extension *.exe to copy from portable devices to computer, it is working OK. But what happen users rename the *.exe file to *.doc or anything else then they are able to copy to computer and rename again to *.exe. Why SEP does not detect this rename of *.exe file

Thanks
