9.5.1
Defined Approach Requirements: 
POI devices that capture payment card data via direct physical interaction with the payment card form factor are protected from tampering and unauthorized substitution, including the following:

Customized Approach Objective:
The entity has defined procedures to protect and manage point of interaction devices. Expectations, controls, and oversight for the management and protection of POI devices are defined and adhered to by affected personnel. 

Applicability Notes:
These requirements apply to deployed POI devices used in card-present transactions (that is, a payment card form factor such as a card that is swiped, tapped, or dipped). These requirements do not apply to:

Defined Approach Testing Procedures:

Purpose:
Criminals attempt to steal payment card data by stealing and/or manipulating card-reading devices and terminals. Criminals will try to steal devices so they can learn how to break into them, and they often try to replace legitimate devices with fraudulent devices that send them payment card data every time a card is entered. 
They will also try to add “skimming” components to the outside of devices, which are designed to capture payment card data before it enters the device—for example, by attaching an additional card reader on top of the legitimate card reader so that the payment card data is captured twice: once by the criminal’s component and then by the device’s legitimate component. In this way, transactions may still be completed without interruption while the criminal is “skimming” the payment card data during the process. 

Good Practice:
Entities may consider implementing protection from tampering and unauthorized substitution for:

Additional best practices on skimming prevention are available on the PCI SSC website. 

9.5.1.3
Defined Approach Requirements: 
Training is provided for personnel in POI environments to be aware of attempted tampering or replacement of POI devices, and includes:

Customized Approach Objective:
Personnel are knowledgeable about the types of attacks against POI devices, the entity’s technical and procedural countermeasures, and can access assistance and guidance when required. 

Defined Approach Testing Procedures:

Purpose:
Criminals will often pose as authorized maintenance personnel to gain access to POI devices. 

Good Practice:
Personnel training should include being alert to and questioning anyone who shows up to do POI maintenance to ensure they are authorized and have a valid work order, including any agents, maintenance or repair personnel, technicians, service providers, or other third parties. All third parties requesting access to devices should always be verified before being provided access—for example, by checking with management or phoning the POI maintenance company, such as the vendor or acquirer, for verification. Many criminals will try to fool personnel by dressing for the part (for example, carrying toolboxes and dressed in work apparel), and could also be knowledgeable about locations of devices, so personnel should be trained to always follow procedures. 
Another trick that criminals use is to send a “new” POI device with instructions for swapping it with a legitimate device and “returning” the legitimate device. The criminals may even provide return postage to their specified address. Therefore, personnel should always verify with their manager or supplier that the device is legitimate and came from a trusted source before installing it or using it for business. 

Examples:
Suspicious behavior that personnel should be aware of includes attempts by unknown persons to unplug or open devices. 
Ensuring personnel are aware of mechanisms for reporting suspicious behavior and who to report such behavior to—for example, a manager or security officer—will help reduce the likelihood and potential impact of a device being tampered with or substituted.
