1 4 CHAPTER Solution Implementation Overview Cisco customers have asked Cisco to provide insight into how Cisco products can be used to address PCI DSS 2.0 requirements. To fully accomplish this goal, Cisco hired an auditor and went through the same process as organizations. To audit Cisco products for the capability to address compliance, they had to be installed and configured within a representative design. This chapter demonstrates how the Cisco PCI solution was installed and configured to address the specifications of PCI 2.0. Cisco partnered with RSA, HyTrust, EMC, VCE, and Verizon Business to create a comprehensive design that reflected the framework and architectural principles discussed in earlier chapters. The Cisco PCI solution was validated in the Cisco Lab in San Jose, California. The branches, data center, WAN, and Internet edge network infrastructures were built using Cisco best practice design guides, as represented by the Cisco enterprise architecture ( The individual components were installed and configured to adhere to PCI 2.0 specifications. Verizon Business then conducted an assessment of the design and advised on remediation for specific configurations of individual components. After the remediation was complete, Verizon Business provided a detailed reference architecture report (see Appendix C, Verizon Business Reference Architecture Report Cisco PCI Solution. ) Tip An architecture is a strategic structure for the consistent design, construction, and operation of systems to achieve a desired set of outcomes. A design is a tactical implementation of an architectural strategy, using specific configurations of products to satisfy business requirements. Chapter 3, Solution Architecture, describes the enterprise architecture with regards to compliance. This chapter demonstrates a design or, in other words, a specific implementation of components to achieve these principles. Various designs can result from the solution architecture. The design that was implemented is not intended to represent the only way that Cisco and partner products can be installed to address PCI. It is intended to provide an example showing how and what was used to achieve the principles described in Chapter 3, Solution Architecture. 4-1

2 Although every company has specific considerations that vary from this implementation, these designs and the configurations of the components in Appendix E, Detailed Full Running Configurations, provide an instructive example of what is needed to secure credit card data. Each component selected was audited for its capabilities, and that assessment is covered in the next chapter. In each section, the reference architecture is shown with the corresponding design that was implemented and validated within the Cisco PCI laboratories. The full configurations of each individual component are available in Appendix E, Detailed Full Running Configurations. The infrastructure layer of the solution framework addresses the components such as routers, switches, firewalls, and security components, as shown in Figure 4-1.

The data center consists of a single aggregation block based on the Data Center 3.0 architecture. The Internet edge is representative of both the e-commerce and partner edge for the purposes of validation. The following sections describe this enterprise-wide design in more detail, and demonstrate what was implemented within the lab. Large Branch Branches Multiple branch footprints were implemented that address a variety of business objectives. Each branch footprint section contains designs that were extracted from the reference architecture. Each design contains the following: Reference architecture Branch design Logical topology Addressing plan Components selected 4-4

Note Each of these branch designs includes a variety of components that can be interchangeably used between them, depending on business requirements. For validation purposes, it was not necessary to implement all possible components in each design. Small Branch Architecture The small branch network scenario, shown in Figure 4-4, meets the following design requirements: Branch size averages between square feet Fewer than 25 devices requiring network connectivity Single router with firewall/ips, integrated Ethernet switch, compact switch, and power-over-ethernet (PoE) Preference for integrated services within fewer network components because of physical space requirements Wireless connectivity Figure 4-4 Small Branch Architecture PoS VLAN/ WLAN Mobile PoS PoS Cash Register PoS Server Data VLAN/WLAN Branch Worker PC Inventory Management Cisco Integrated Services Router (IOS Security and Ethernet Switch) Cisco AG WLAN Access Point Primary WAN Connection Alternate WAN Connection Centralized Management Servers

6 Small Branch Small Design The small branch reference architecture is a powerful platform for running an enterprise that requires simplicity and a compact form factor. This combination appeals to many formats that can include the following: Small branch Specialty shops, discount businesses Mini branches Fuel stations, mall outlet Convenience branches Pop-up stores, health centers, mall kiosks Managed service provider branch WAN access controlled by service provider This network architecture is widely used and consolidates many services into fewer infrastructure components. The small branch also supports a variety of business application models because an integrated Ethernet switch supports high-speed LAN services. In addition, an integrated content engine supports centralized application optimization requirements such as Web Cache Communications Protocol (WCCP)-based caching, pre-positioning of data, local media streaming, and other application velocity services. Advantages include the following: Lower cost per branch Fewer parts to spare Fewer software images to maintain Lower equipment maintenance costs Limitations include the following: Decreased levels of network resilience Greater potential downtime because of single points of failure Figure 4-5 shows the small branch network design. 4-6

11 Chapter 4 Solution Implementation Medium Branch Architecture The medium branch network scenario, shown in Figure 4-9, meets the following design requirements: Branch size averages between 6,000 18,000 square feet The physical size of the branch is smaller than a large branch, so a distribution layer of network switches is not required Number of devices connecting to the network averages devices Redundant LAN and WAN infrastructures with firewall/ips Wireless connectivity Figure 4-9 Medium Branch Architecture PoS VLAN/ WLAN Mobile PoS PoS Cash Register PoS Server Data VLAN/WLAN Branch Worker PC Inventory Management Personal Shopper/ PDA for Enhanced Customer Service Vendor/Guest WVLAN Partner Device for Inventory Management Management VLAN Cisco ISR (WLC and WAAS) Catalyst Switches (Power over Ethernet and Security) Cisco ISR IOS (VSOM/VSMS and UCS-X) Cisco a/b/g WLAN Access Points Primary WAN Connection Alternate WAN Connection Centralized Management Servers The medium branch reference architecture is designed for enterprise businesses that require network resilience and increased levels of application availability over the small branch architecture and its single-threaded, simple approach. As more mission-critical applications and services converge onto the IP infrastructure, network uptime and application availability are more important. The dual-router and dual-lan switch design of the medium branch supports these requirements. Each of the Cisco ISR routers can run Cisco IOS Software security services and other branch communication services 4-11

12 simultaneously. Each of the Cisco ISR routers is connected to a dedicated WAN connection. Hot Standby Routing Protocol (HSRP) is used to ensure network resilience in the event that the network connection fails. The access layer of the network offers enhanced levels of flexibility and more access ports compared to the small branch. Up to 12 wireless access points can be installed in the branch, supported by the Cisco Wireless Control System (WCS) controller as tested and without adding more controllers. The distributed Cisco Catalyst switches can support a combination of larger physical buildings or a larger number of endpoints than the small branch. Advantages include the following: More adaptive access layer with support for a greater number of endpoints and more diverse building requirements (multiple floors, sub-areas, and so on) Improved network resilience through parallel device design Improved network and application availability through parallel paths Limitations include the following: No distribution layer between core layer (the ISR) and the access layer switches Single WCS Controller decreases in-branch resilience of the wireless network; the recommendation is to have branch APs fallback to the central WCS controller if the local WCS controller fails, or to install dual-local WCS controllers. 4-12

14 Large Branch Architecture The large branch network scenario, shown in Figure 4-11, meets the following design requirements: Branch size averages between 15, ,000 square feet More than 100 devices per branch requiring network connectivity Multiple routers with firewall/ips for primary and backup network requirements Preference for a combination of network services distributed within the branch to meet resilience and application availability requirements Tiered network architecture within the branch; distribution layer switches are employed between the central network services core and the access layer connecting to the network endpoints (POS, wireless APs, servers) Figure 4-11 Large Branch Architecture PoS VLAN/ WLAN PoS PoS Server Personal Shopper/ PDA Customer Service Vendor Device for Inventory Management Vendor/Guest WVLAN Mobile PoS Branch Worker PC Inventory Management Data VLAN/ WVLAN Cisco a/b/g WLAN Access Points Management VLAN Catalyst Switches (Distribution and Access) Wireless Controllers Cisco ISRs (IOS Security) Primary WAN Connection Alternate WAN Connection Centralized Management Servers

15 Chapter 4 Solution Implementation The large branch reference architecture takes some of the elements of Cisco campus network architecture recommendations and adapts them to a large branch environment. Network traffic can be better segmented (logically and physically) to meet business requirements. The distribution layer of the large branch architecture can greatly improve LAN performance while offering enhanced physical media connections (that is, fiber and copper for connection to remote access layer switches and wireless access points). A larger number of endpoints can be added to the network to meet business requirements. This type of architecture is widely used by large format organizations globally. Dual routers and distribution layer media flexibility greatly improve network serviceability because the network is highly available and scales to support the large branch requirements. Routine maintenance and upgrades can be scheduled and performed more frequently or during normal business hours because of parallel path design. Advantages include the following: Highest network resilience based on highly available design Port density and fiber density for large locations Increase segmentation of traffic Scalable to accommodate shifting requirements in large branches Limitations include the following: Higher cost because of network resilience based on highly available design These branch network designs are capable of helping an organization achieve PCI compliance, and also serve as the scalable platform for new services and applications 4-15

17 Chapter 4 Solution Implementation Data Center The data center is where centralized data processing, data storage, and data communications take place (see Figure 4-13). The data center is also the place where management systems are deployed. The data center provides centralized control from an administrative perspective because it is typically where the tools that are used to monitor and enforce compliance are deployed.

Standardized equipment and software images, deployed in a modular, layered approach, simplify configuration management and increase the systems availability. The highly available data center design permits highly resilient access from branches to core data and storage services. WAN aggregation alternatives allow flexible selection of service provider network offerings. The service aggregation design allows for a modular approach to adding new access layers and managing shared network services (for example, firewall, IPS, application networking, wireless management) 4-17

18 Firewall, IPS, and application networking services are available at the service and aggregation layers of the data center. Scalability to accommodate shifting requirements in data center compute and storage requirements. WAN access speeds are typically the limiting factor between the branch network systems and the WAN aggregation layer. It is typical for organizations to over-subscribe the WAN circuits between the branches and the WAN edge aggregation router. Over-subscription can cause inconsistent results and packet loss of payment card information in the event that more traffic enters the WAN circuit simultaneously. Backup network connections from branch networks to the data center are recommended when payment card information is transported via the WAN. Figure 4-14 shows the data center design. Figure 4-14 Data Center Design Internet Edge Management Servers Application Servers Data Center DMZ Servers MSE DMZ IronPort IronPort Access www www Service Aggregation Core WAN Aggregation Data centers can house many types of functions and the term itself can encompass narrow and broad aspects. For the purposes of this guide, data centers include the following functions: WAN aggregation layer Aggregates the branch and backstage WAN connections to the core Core layer Highly available, high-speed area that is the central point of connectivity to all data center areas Aggregation block Aggregates the services of one area and connects that area to the core, including Vblock1 design Internet edge Secure connectivity to the Internet 4-18

24 Addressing and Routing Disclosure PCI requirement states that merchants must not disclose private addressing and routing information. An enterprise contains two segments: Public Where Internet services are hosted Private Where internal systems reside that are not directly accessible from outside the company Both may be deployed internally within an enterprise data center or other PIN. The private information must be protected and not propagated out to untrusted parties. In 2013, it is common for enterprises to deploy an IPv6 Internet presence by using the Server Load Balancing (SLB) to do protocol family translation; that is, when the SLB receives an IPv6 inbound connection from the Internet, the SLB translates this connection on the fly into an IPv4 connection to the real servers. In this solution, PCI was met because all the security pieces for IPv4 are also used for IPv6 connections. Moreover, the servers where the information resides have no IPv6 addresses and cannot be reached over IPv6. The attack surface of the servers is strictly the IPv4 attack surface. Note For more information on the Cisco ACE Application Control Engine Module, see the following URL: A best practice when implementing IPv6 is a phased approach. Figure 4-20 illustrates the scenario described above as the first phase of an IPv6 deployment. 4-24
