(SDN may be good for businesses and the people implementing them, but if you are the user, its hard to regain control.) Seems like SDN has been implemented on my own home network. We have Cisco E2000, an ISP Provider set up. Now it seems, Either intruders or practicing IT family members have taken over network and security without warning. Over time, Clues have led me to believe that cell phones have been used as modems, the hard drive on laptops are locked or disappear. In addition; computers and cell phones have been remotely set and locked, to reboot with preinstalled windows packages , with different settings than originally purchased.
Software/Hardware used: Cisco, smartphone, cellphones! Preinstalled windows packages
