Introduction
This is the non-proprietary Cryptographic Module Security Policy for the Cisco 1721, 1760, 2621XM,
2651XM, 2691, 3725, 3745, and 7206 VXR NPE-400 routers. This security policy describes how the
routers meet the security requirements of FIPS 140-2, and how to operate the routers in a secure FIPS
140-2 mode. This policy was prepared as part of the Level 2 FIPS 140-2 certification of the routers.
FIPS 140-2 (Federal Information Processing Standards Publication 140-2—Security Requirements for
Cryptographic Modules) details the U.S. Government requirements for cryptographic modules. More
information about the FIPS 140-2 standard and validation program is available on the NIST website at
http://csrc.nist.gov/cryptval/.

VXR NPE-400 Routers
Branch office networking requirements are dramatically evolving, driven by web and e-commerce
applications to enhance productivity and merging the voice and data infrastructure to reduce costs. The
Cisco 1721, 1760, 2621XM, 2651XM, 2691, 3725, 3745, and 7206 VXR NPE-400 modular
multi-service routers offer versatility, integration, and security to branch offices. With numerous WAN
Interface Cards (WICs) and Network Modules (NMs) available, the modular architecture of the Cisco
router easily allows interfaces to be upgraded to accommodate network expansion. The Cisco 1721,
1760, 2621XM, 2651XM, 2691, 3725, 3745, and 7206 VXR NPE-400 provide a scalable, secure,
manageable remote access server that meets FIPS 140-2 Level 2 requirements as a multiple-chip
embedded module. This section describes the general features and functionality provided by the Cisco
1721, 1760, 2621XM, 2651XM, 2691, 3725, 3745, and 7206 VXR NPE-400 routers. Additional
adapters (e.g. WICs and other modules) are excluded from the validation.

The cryptographic boundary is defined as encompassing the "top," "front," "left," "right," and "bottom"
surfaces of the case; all portions of the "backplane" of the case which are not designed to accommodate
a WIC; and the inverse of the three-dimensional space within the case that would be occupied by an
installed WIC. The cryptographic boundary includes the connection apparatus between the WIC and the
motherboard/daughterboard that hosts the WIC, but the boundary does not include the WIC itself. In
other words, the cryptographic boundary encompasses all hardware components within the case of the
device except any installed modular WICs. All of the functionality discussed in this document is
provided by components within this cryptographic boundary.
The 1760 requires that a special opacity shield be installed over the right-hand side air vents in order to
operate in FIPS-approved mode. The shield decreases the effective size of the vent holes, reducing
visibility within the cryptographic boundary to FIPS-approved specifications. The shield is
self-adhering to the side of the chassis. To install the shield, remove it from its paper backing and apply
the shield to the chassis, aligning the holes on the shield with the vent-holes on the side of the chassis.
Figure 2 demonstrates the proper application of the shield.

Cisco IOS features such as tunneling, data encryption, and termination of Remote Access WANs via
IPSec, Layer 2 Forwarding (L2F) and Layer 2 Tunneling Protocols (L2TP) make the Cisco 1700 an ideal

Cisco 1721 and 1760 Module Interfaces
The interfaces for the router are located on the rear panel of the Cisco 1721 and the front panel of the
Cisco 1760 as shown in Figure 3.
Figure 3 Cisco 1721 and Cisco 1760 Physical Interfaces
The Cisco 1721 and 1760 routers feature console and auxiliary ports, single fixed LAN interfaces, two
Cisco WAN interface card (WIC) slots on the 1721, and two WIC slots and two Voice interface card
(VIC) slots on the 1760. WAN interface cards support a variety of serial, ISDN BRI, and integrated
CSU/DSU options for primary and backup WAN connectivity. All Cisco 1700 series routers include an
auxiliary port supporting 115Kbps Dial-On-Demand Routing, ideal for back-up WAN connectivity.
A WIC is inserted into one of the WIC slots, which are located on the back panel of the 1721 and the
front panel of the 1760. WICs interface directly with the processor, and cannot perform cryptographic
functions; they only serve as a data input and data output physical interface.
The physical interfaces include a power plug for the power supply and a power switch. The router has
one Fast Ethernet (10/100 RJ-45) connector for data transfers in and out. The module also has two other
RJ-45 connectors on the back panel for a console terminal for local system access and an auxiliary port
