anyone here have opinion about Android security for common-off-the-shelf "COTS" tablets (like Samsung or other)? as example, what security concerns should i have using a Android based COTS tablet for accessing a web based PCI POS application over wifi (Meraki is the wifi). in my case the device will be under a MDM layer and is not BYOD, but i have reservations about using COTS Android tablet for such. i could build my own Android from the distro source, but in this case the security question is around COTS Android, etc.
