This document is to be used by those merchants and service providers who require an onsite review to validate compliance with the Payment Card Industry (PCI) Data Security Standard and to create the Report on Compliance.
Note that these PCI Data Security Requirements apply to all Members, merchants, and service providers that store, process, or transmit cardholder data. Additionally, these security requirements apply to all “system components” which is defined as any network component, server, or application included in, or connected to, the cardholder data environment. Network components, include, but are not limited to, firewalls, switches, routers, wireless access points, network appliances, and other security appliances. Servers include, but are not limited to, web, database, authentication, DNS, mail, proxy, and NTP. Applications include all purchased and custom applications, including both internal and external (web) applications.
Scope of the Assessment
For service providers required to undergo an annual onsite review, compliance validation must be performed on all system components where cardholder data is processed, stored, or transmitted, unless otherwise specified.
For merchants required to undergo an annual onsite review, the scope of compliance validation is focused on any system(s) or system component(s) related to authorization and settlement where cardholder data is processed, stored, or transmitted, including:
	All external connections into the merchant network (e.g.; employee remote access, payment card company, third party access for processing, and maintenance)
	All connections to and from the authorization and settlement environment (e.g.; connections for employee access or for devices such as firewalls and routers)
	Any data repositories outside of the authorization and settlement environment where more than 500 thousand account numbers are stored.
	POS Terminals may be excluded, however: 
-	If a POS environment is IP-based and there is external access, via Internet, wireless, VPN, dial-in, broadband, or publicly accessible machines (such as kiosks), to the merchant location, the POS environment must be must be included in the scope of the on-site review.
-	If a POS environment is either not IP-based or there is no external access to the merchant location, begin review at the connection into the authorization and settlement environment.
Note: The POS environment is the environment in which a transaction takes place at a merchant location (i.e. retail store, restaurant, hotel property, gas station, supermarket, or other point-of-sale location). An IP-based POS environment is one in which transactions are stored, processed, or transmitted on IP-based systems, or systems communicating via TCP/IP.

Wireless
If wireless technology is used to transmit, process, or store cardholder data (e.g., point-of-sale transactions, “line-busting”, etc.), or if a wireless LAN is connected to or part of the cardholder environment (e.g., not clearly separated by a firewall), the Requirements and Testing Procedures for wireless environments must be performed as well. Wireless security is not mature yet, but these requirements specify that basic wireless security features be implemented to provide minimal protection. Since wireless technologies cannot yet be secured well, we recommend, before wireless technology is put in place, that a company carefully evaluate the need for the technology against the risk. Consider deploying it only for non-sensitive data transmission, or waiting for more secure technology.
Outsourcing
For those entities that outsource processing, transmitting, or storage of cardholder data to third-party service providers, the Report On Compliance must document the role of each service provider; however, these service providers are responsible for validating their own compliance with the PCI Data Security Standard independent of their customers. Additionally, merchants and service providers must contractually require all associated third parties with access to cardholder data to adhere to the PCI Data Security Standard. Refer to Requirement 12.8 in this document for details. 
Sampling
The assessor can select a sample of system components to test. The sample must be a representative selection of all of the types of system components, and include a variety of operating systems, functions, and applications as applicable to the area being reviewed. For example, the reviewer could choose Sun servers running Apache WWW, NT servers running Oracle, mainframe systems running legacy card processing applications, data transfer servers running HP-UX, Linux Servers running MYSQL, etc. If all applications run from a single OS (e.g., NT, Sun, etc.), then the sample should still include a variety of applications (e.g., database servers, web servers, data transfer servers, etc.).
See the first page of this document for the definition of “system components.”
Report On Compliance
This document is to be used as the template to create the Report on Compliance. Acquirers, merchants, and service providers will need to follow each payment card company’s respective reporting requirements to ensure each payment card company acknowledges an entity’s compliance status. Please contact each payment card company to determine to whom the results should be submitted. 
All assessors must apply the following report content and format when completing the Report On Compliance (ROC):
1. 	Contact Information and Report Date
	Include contact information for the merchant or service provider and assessor.
	Date of report.
2. 	Executive Summary
	Include the following:
	Business description.
	List service providers and other entities with which the company shares cardholder data.
	List processor relationships
	Whether entity is directly connected to a payment card company.
	For merchants, POS products used.
	Any wholly-owned entities that require compliance with the PCI Data Security Standard.
	Any international entities that require compliance with the PCI Data Security Standard.
	Any wireless LANs and/or wireless POS terminals connected to the cardholder environment.
3. 	Description of Scope of Work and Approach Taken
	Version of the Security Audit Procedures document used to conduct the assessment.
	Timeframe of assessment.
	Environment on which the assessment was focused (i.e., client’s Internet access points, internal corporate network, processing points for the payment card company, etc.).
	Any areas excluded from the review.
	Brief description or high-level drawing of network topology and controls.
	List of those interviewed.
	List of hardware and critical (e.g., database or encryption) software in use.
	For Managed Service Provider (MSP) reviews, clearly delineate which requirements in this document apply to the MSP (and are included in the review), and which are not included in the review and are the responsibility of the MSPs’ customers to include in their own reviews. Include information about which of the MSP’s IP addresses are scanned as part of the MSP’s quarterly vulnerability scans, and which IP addresses are the responsibility of the MSP’s customers to include in their own quarterly scans.
4. 	Quarterly Scan Results
	Please briefly summarize the 4 most recent quarterly scan results in comments at Requirement 11.2
	The scan should cover all externally accessible (Internet-facing) IP addresses in existence at the entity.
5.	Findings and Observations
	All assessors must utilize the following template to provide detailed report descriptions and findings on each requirement and sub-requirement.
	Where applicable, document any compensating controls considered to conclude that a control is in place. See Definitions on the next page for further discussion of compensating controls.
Revalidation of Open Items 
A “controls in place” report is required for compliance. If an initial report is issued with open items, the entity should correct all open items, and the assessor should revalidate that the remediation occurred and addressed all requirements. After the revalidation, the assessor should reissue a fully compliant ROC, submitted per the above instructions.
Definitions
For the purpose of the Security Audit Procedures, the following definitions will be used:
Requirements	The PCI Data Security Standard requirements by which an assessor validates an entity’s compliance.
Compensating Controls	Controls put in place as alternatives to controls defined in the “Requirements” columns. These controls should also be examined by the assessor, and, in the assessors’ opinion, should meet the intention and rigor of the original requirement. Compensating controls should be “above and beyond” other PCI requirements; it is not a compensating control to simply be in compliance with other requirements in this document.
Testing Procedure	Processes to be followed by the assessor to address individual requirements and testing considerations. These testing procedures list detailed controls that the assessor should find in place to support the requirement. Where these detailed controls are not in place exactly as stated, or cannot be put in place due to technical or other constraints, the assessor should examine compensating controls.
In Place	Please provide a brief description of controls found in place, including those controls found to be in place as a result of compensating controls.
Not In Place	Please provide a brief description controls that are not in place. If a requirement is “Not Applicable” (N/A), please explain.
Target Date/ Comments	For those controls “Not In Place” include a target date that the entity expects to have controls “In Place.” Any additional notes or comments may be included here as well.
Requirement 1: Install and maintain a firewall configuration to protect data. Firewalls are computer devices that control computer traffic allowed into a company’s network from outside, as well as traffic into more  sensitive areas within a company’s internal network. All systems need to be protected from unauthorized access from the Internet, whether for  e-commerce, employees’ Internet-based access via desktop browsers, or employees’ email access. Often, seemingly insignificant paths to and from the Internet can provide unprotected pathways into key systems. Firewalls are a key protection mechanism for any computer network.

Two or three central time servers within the organization receive external time signals (directly from a special radio, GPS satellites, or other external sources-based on International Atomic Time and UTC (formerly GMT)), peer with each other to keep accurate time, and share the time with other internal servers (i.e., internal servers should not be all be receiving time signals from external sources).  	NTP is running the most recent version. 	Specific external hosts are designated from which the time servers will accept NTP time updates (to prevent an attacker from changing the clock). Optionally, those updates can be encrypted with a symmetric key, and access control lists can be created that specify the IP addresses of client machines that will be provided with the NTP service (to prevent unauthorized use of internal time servers).
