Penetration testing was much like taking a battering ram to the door of the fortress. Keep pounding away and maybe find a secret backdoor to enter through. But what happens if pieces of the network are outside of the fortress? With the flurry of Internet of Things devices, is it harder to conduct a pen test with that many devices and end points?
Claud Xiao, principal security researcher, Unit 42 at Palo Alto Networks, said for just testing some network services on IoT devices in a black box way, the difficulty level and the steps are similar with regular pen testing. But if you’re discovering vulnerabilities via analyzing firmware or via analyzing wireless communications (e.g., Bluetooth or ZigBee), that’s much harder.
