The Result and Impact
9
• The Industry Experts’ Analysis– They passed its PCI Compliance audit in September
– They may have not done enough to wall off its payment systems from the rest of its vast network
people who work with large corporate networks said.
– The company has since moved to isolate its different platforms and networks to make it harder for a
hacker to move between them
an executive said.
– So-called segmentation issues, where computer systems that shouldn't be connected for security reasons
are in fact linked, are a problem at a number of retailers
a person familiar with retail breaches said.
– There shouldn't have been a route between a network for an outside contractor and the one for
payment data
people familiar with large corporate networks said.

Solution Overview Cloud-managed IoT/M2M routers dedicated to a single use
Typically used by 3rd-parties for BYON (Bring Your Own Network)
Creates physically separate networks for increased security
Benefits
Increases PCI Compliance by reducing scope of network– PCI Auditors must evaluate everything in the Cardholder Data Environment (CDI)
– Removing usage from the CDI such as customer WiFi, digital signage, 3rd=parties, etc reduces scope, increases PCI compliance, and reduces security risk.
– Dedicated networks for POS devices (checkout, kiosk, etc) have fewer security risks
Eliminates 3rd-party dependencies on branch/store network– 3rd-parties include kiosks, store-within-a-store, digital signage, security, HVAC, energy mgmt– 4G-LTE enables network connectivity with no wires to install or manage– 3rd-parties prefer to homogeneous networks for control, consistency and manageability
Security through Separation– Eliminates the opportunity for thieves to hack into the network and launch a “pivot attack”
– Network segmentation that is “logical” rather than “physical” is prone to misconfiguration
– The Target breach highlights the susceptibility of monolithic networks to a pivot attack.
Enables Offload of Non-Core Traffic from the Private Network– Eliminates the opportunity for thieves to hack into the network and launch a “pivot attack”
– Network segmentation that is “logical” rather than “physical” is prone to misconfiguration
