Version 1.3
June 2, 2004

Introduction

This is the non-proprietary Cryptographic Module Security Policy for the 2621XM and 2651XM
Modular Access Routers with AIM-VPN/EP. This security policy describes how the 2621XM and
2651XM routers (Hardware Version: 2621XM, 2651XM; AIM-VPN/EP: Hardware Version 1.0, Board
Version B0; Firmwar e Version: IOS 12.3(3d)) meet the security requirements of FIPS 140-2, and ho w t o
operate the 2621XM and 2651XM routers in a secure FIPS 140-2 mode. This policy was prepared as
part of the Level 2 FIPS 140-2 validation of the 2621XM and 2651XM 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

The 2621XM and 2651XM Routers are multiple-chip standalone cryptographic modules. 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 or Network Module; and the inverse of the three-dimensional space within the case that would be
occupied by an installed WIC or Network Modu le. The cryptographic boundary includ es the connection
apparatus between the WIC or Network Module and the motherboard/daughterboard that hosts the WIC
or Network Module, but the boundary does not include the WIC or Network Module itself. In other
words, the cryptographic boundary encompasses all hardware components within the case of the device
except any installed modular WICs or Network Modules. All of the functionality discussed in this
document is provided by components within this cryptographic boundary.

The Cisco 2621XM and 2651XM routers incorporate an AIM-VPN/EP cryptographic accelerator card.
The AIM-VPN/EP is located inside the module chassis, and is installed directly on the motherboard.

Cisco IOS features such as tunneling, data encryption, and termination of Remote Access WANs via
IPSec, Layer 2 Forwarding (L2F) and Layer 2 T unnelin g Protocols (L2TP) make t he Cisco 2600 an ideal
platform for building virtual private networks or outsourced dial solutions. Cisco 2600`s RISC-based
processor provides the power needed for the dynamic requirements of the remote branch office,
achieving wire speed Ethernet to Ethernet routing with up to 30 thousand packets per second (Kpps)
throughput capacity for the 2621XM, an d 40 Kpps for t he 2651XM .

The Cisco 2621XM and 2651XM routers feature a console port, an auxiliary port, dual fixed LAN
interfaces, a Network Module slot, and two WIC slots.

LAN support includes single and dual Ethernet options; 10/100 Mbps auto-sensing Ethernet; mixed
Token-Ring and Ethernet; and single Token Ring chassis versions.

WAN interface cards support a variety of serial, ISDN BRI, and integrated CSU/DSU options for
primary and backup WAN connectivity. Available Network Modules support multi-service
voice/data/fax integration, departmental dial concentration, and high-density serial options

All Cisco 2600 series routers include an auxiliary port supporting 115Kbps Dial-On-Demand Routing,
ideal for back-up WAN connectivity.

When a Network Module is inserted, it fits into an adapter called the Network Module expansion bus.
The expansion bus interacts with the PCI bridge i n the same w ay that the f ixed LAN ports do; therefore,
no critical security parameters pass through the Network Module (just as they don't pass through the
LAN ports). Network modules do not perform any cryptographic functions.

WICs are similar to Network Modules in that they greatly increase the router's flexibility. A WIC is
inserted into one of two slots, which are l ocated abov e the fix ed LAN ports. WICs interface di rectly with
the processor. They do not interface with the cryptographic card; therefore no security parameters will
pass through them. WICs 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
two Fast Ethernet (10/100 RJ-45 ) connectors 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
for remote system access or dial backup using a modem. The 10/100Base-T LAN ports have
Link/Activity, 10/100Mbps, and half/full duplex LEDs. Figure 3 shows the LEDs located on the rear
panel with descriptions de tailed in Table 1:

Roles and Services

Authentication is role-based. There are two main roles in the router that operators may assume: the
Crypto Officer role and the User role. The administrator of the router assumes the Crypto Officer role
in order to configure and maintain the ro uter using Crypto Off icer services, while the Users exercise only
the basic User services. Both roles are authenticated by providing a valid username and password. The
configuration of the encryption and decryption functionality is performed only by the Crypto Officer
after authentication to the Crypto Officer role by providing a valid Crypto Officer username and
password. Once the Crypto Of ficer conf igured the encryption an d decryption functionality, the User can
use this functionality after authentication to the User role by providing a valid User username and
password. The Crypto Officer can also use the encryption and decryption functionality after
authentication to the Crypto Officer role. The module supports RADIUS and TACACS+ for
authentication and they are used in the FIPS mode. A complete description of all the management and
configuration capabilities of the Cisco 2621XM and 2651XM Routers can be found in the Performing
Basic System Management manual and in the online help for the router.

The User and Crypto Officer passwords and the RADIUS/TACACS+ shared secrets must each be at least
8 alphanumeric characters in length. See the “Secure Operation of the Cisco 2621XM/2651XM Router”

section on page 17, for more information. If only integers 0-9 are used without repetition for an 8 digit

PIN, the probability of randomly guessing the correct sequence is 1 in 1,814,400. Including the rest of
the alphanumeric characters drastically decreases the odds of guessing the correct sequence.

Status Output Interface

Crypto Officer Services

During initial configuration of the router, the Cr ypto Officer password (the “enable” password) is
defined. A Crypto Officer may assign permission to access the Crypto Officer role to additional
accounts, thereby creating additional Crypto Officers.

The Crypto Officer role is responsible for the configuration and maintenance of the router. The Crypto
Officer services consist of the following:

• Configure the router—define network interfaces and settings, create command aliases, set the

protocols the router will support, enable interfaces and network services, set system date and time,
and load authentication information.

The 2621XM/2651XM Router

User Services

• Define Rules and Filters—create packet Filters that are applied to User data streams on each

interface. Each Filter consists of a set of Rules, which define a set o f packets to permit or deny based
characteristics such as protocol ID, addresses, ports, TCP connection establishment, or packet
direction.

• Status Functions—view the router configuration, routing tables, active sessions, use Gets to view

SNMP MIB II statistics, health, temperature, memory status, voltage, packet statistics, review
accounting logs, and view physical interface status

• Manage the router—log off users, shutdown or reload the outer, manually back up router

configurations, view complete configurations, manager user rights, and restore router
configurations.

• Set Encryption/Bypass—set up the configuration tables for IP tunneling. Set keys and algorithms

to be used for each IP range or allow plaintext packets to be set from specified IP address.

• Change Network Modules—insert and remove modules in the Network Module slot as described

in the “Initial Setup” section of this document.

• Change WAN Interface Cards—insert and remove WICs in the WAN interface slot as described

in the “Initial Setup” section of this document.

A User enters the system by accessing the console port with a terminal program. The IOS prompts the
User for their password. If the password is correct, the User is allowed entry to the IOS executive
program. The services available to the User role consist of the following:

• Status Functions—view state of interfaces, state of layer 2 protocols, version of IOS currently

• Network Functions—connect to other network devices through outgoing telnet, PPP, etc. and

• Terminal Functions—adjust the terminal session (e.g., lock the terminal, adjust flow control)

• Directory Services—display directory of files kept in flash memory

Physical Security

The router is entirely encased by a thick steel chassis. The rear of the unit provides 1 Network Module
slot, 2 WIC slots, on-board LAN connectors, Console/Aux iliary connectors, the po wer cable connection
and a power switch. The top portion of the chassis may be remov ed (see Figure 5) to allo w access to the
motherboard, memory, and expansion slots.

Any NM or WIC slot, which is not populat ed with a N M or WIC, must be popu lated with an appropriate
slot cover in order to operate in a FIPS compliant mode. The slot covers are included with each router,
and additional covers may be ordered from Ci sco. The same procedure mentioned below to apply tamper
evidence labels for NMs and WICs must also be followed to apply tamper evidence labels for the slot
covers.

Once the router has been configured in to meet FIPS 140-2 Level 2 requirements, the router cannot be
accessed without signs of tampering. To seal the system, apply serialized tamper-evidence labels as
follows:

9497

Step 1 Clean the cover of any grease, dirt, or oil before applying the tamper evidence labels. Alcohol-based

cleaning pads are recommended for this purpose. The temperature of the router should be above 10 C.

Step 2 Place the first label on the router as shown in Figure 6. The tamper evidence label should be placed so

that the one half of the tamper evidence label covers the enclosure and the other half covers the side of
the router. Any attempt to remove the enclosure will leave tamper evidence.

Step 3 Place the second label on the router as shown in Figure 6. The tamper evidence label should be placed

so that the one half of the tamper evidence label covers the enclosure and the other half covers the side
of the router. Any attempt to remove the enclosure will leave tamper evidence.

Step 4 Place the third label on the router as shown in Figure 6. The tamper evidence label should be placed so

that the one half of the label covers the enclosure and the other half covers the Network Module slot.
Any attempt to remove a Network Module will leave tamper evidence.

Step 5 Place the fourth label on the router as shown in Figure 6. The tamper e vidence label should be placed so

that the half of the label covers the enclosure and the other half covers the WAN interface card slot.
Any attempt to remove a WAN interface card will leave tamper evidence.

Step 6 Place the fifth label on the router as shown in Figure 6. The tamper evidence label should be placed so

that one half of the label covers the enclosure and the other half covers the WAN interface card slot.
Any attempt to remove a WAN interface card will leave tamper evidence.

Step 7 The labels completely cure within five minutes.

ACTIVITY

The tamper evidence seals are p roduced from a s pecial thin g auge vin yl with self- adhesi ve backing. An y
attempt to open the router, remove Network Modules or WIC cards, or the front faceplate will damage
the tamper evidence seals or the painted surface and metal of the module cover. Since the tampe r
evidence seals have non-repeated serial numbers, they may be inspected for damage and compared
against the applied serial numbers to verify that the module has not been tampered. Tamper evidence
seals can also be inspected for signs of tampering, which include the follo wing: curled corners, b ubbling,
crinkling, rips, tears, and slices. The word “OPEN” may appear if the label was peeled back.

Cryptographic Key Management

The router securely administers both cryptographic keys and other critical security parameters such as
passwords. The tamper evidence seals provide physical protection for all keys. All keys are also
protected by the password-protection on the Crypto Of ficer ro le login, and can be zeroized b y the Crypto
Officer. Keys are exchanged manually and entered electronically via manual key exchange or Internet
Key Exchange (IKE).

The modules contain a cryptographic accelerator card (the AIM-VPN/EP), which provides DES (56-bit)
(only for legacy systems) and 3DES (168-bit) IPSec encryption at up to 15Mbps, MD5 and SHA-1
hashing, and has hardware support for DH and RSA key generation.

The module supports the following critical security parameters (CSPs):

1 CSP 1 This is the seed key for X9.31 PRN G. This key is stored in DRAM

and updated periodically after the generation of 400 bites; hence,
it is zeroized periodically. Also, the operator can turn off the
router to zeroize this key.

2 CSP 2 The private exponent used in Diffie-Hellman (DH) exchange.

Zeroized after DH shared secret has been generated.

3 CSP 3 The shared secret within IKE exchange. Zeroized when IKE

session is terminated.

key.

10 CSP 10 The key used to generate IKE skeyid during preshared-key

authentication. “no crypto isakmp ke y” command zeroizes it. This
key can have two forms b ased on whether the k e y is related to the
hostname or the IP address.

11 CSP 11 This key generates keys 3, 4, 5 and 6. This key is zeroized after

generating those keys.

12 CSP 12 The RSA public key used to validate signatures within IKE. These

keys are expired either when CRL (certificate revocation list)
expires or 5 secs after if no CRL exists. After a bove expiration
happens and before a new public key structure is created this key
is deleted. This key does not need to be zeroized because it is a
public key; however, it is zeroized as mentioned here.

13 CSP 13 The fixed key used in Cisco vendor ID generation. This key is

embedded in the module binary image and can be deleted by
erasing the Flash.

14 CSP 14 The IPSec encryption key. Zeroiz ed when IPSec sess ion is

terminated.

15 CSP 15 The IPSec authentication key. The zeroization is the same as

16 CSP 16 The RSA public key of the CA. “no crypto ca trust <label>”

command invalidates the key and it frees the public key label
which in essence prevent use of the key. This key does not need to
be zeroized because it is a public key.

17 CSP 17 This key is a public key of the DNS server. Zeroized using the

same mechanism as above. “no crypto ca trust <label>” command
inv al id at e the DNS server’s pub lic key and it frees the public key
label which in essence prevent use of that key. This label is
different from the label in the above key. This key does not need

19 CSP 19 The ARAP key that is hardcoded in the module binary image.

This key can be deleted by erasing the Flash.

20 CSP 20 This is an ARAP user password used as an authentication key. A

function uses this key in a DES algorithm for authentication.

21 CSP 21 The key used to encrypt values of the configuration f ile. This k ey

is zeroized when the “no key config-key” is issued.

22 CSP 22 This key is used by the router to authenticate itself to the peer . The

router itself gets the password (that is used as this key) from the
AAA server and sends it onto the peer. The password retrieved
from the AAA server is zeroized upon completion of the
authentication attempt.

23 CSP 23 The RSA public key used in SSH. Zeroized after the termination

of the SSH session. This key does not need to be zeroized becau se
it is a public key; However, it is zeroized as mentioned here.

24 CSP 24 The authentication key used in PPP. This key is in the DRAM and

not zeroized at runtime. One can turn off the router to zeroize this
key because it is stored in DRAM.

25 CSP 25 This key is used by the router to authenticate itself to the peer . The

key is identical to #22 except that it is retrieved from the local
database (on the router itself). Issuing the “no username
password” zeroizes the password (that is used as this key) from
the local database.

26 CSP 26 This is th e SSH sessio n key. It is zeroized when the SSH sessio n

is terminated.

27 CSP 27 The password of the User role. This password is zeroized by

overwriting it with a new password.

28 CSP 28 The plaintext password of the CO role. This password is zeroized

by overwriting it with a new password.

29 CSP 29 The ciphertext password of the CO role. However, the algorithm

used to encrypt this password is not FIPS approved. Therefore,
this password is considered plaintext for FIPS purposes. This
password is zeroized by overwriting it with a new password.

30 CSP 30 The RADIUS shared secret. This shared secret is zeroized by

executing the “no” form of the RADIUS shared secret set
command.

Key Zeroization:

The module supports three types of key management scheme s:

• Manual key exchange method that is symmetric. DES/3DES/AES key and HMAC-SHA-1 key are

exchanged manually and entered electronically.

• Internet Key Exchan ge meth od wi th supp ort for exchanging pre-shared keys manually and entering

electronically.

–

The pre-shared keys are used with Diffie-Hellman key agreement technique to derive DES,
3DES or AES keys.

–

The pre-shared key is also used to derive HMAC-SHA-1 key.

• Internet Key Exchange with RSA-signature authentication.

All pre-shared keys are associated with the CO role that created the keys, and the CO role is protected
by a password. Therefore, the CO password is associated with all the pre-shared keys. The Crypto
Officer needs to be authenticated to stor e keys. All Dif fie-Hellman (DH) ke ys agreed upon for individual
tunnels are directly associated with that specific tunnel only via the IKE protocol.

All of the keys and CSPs of the module can be zeroized. Please refer to the Description column of

Table 4 for information on methods to zeroize each key and CSP.

Self-Tests

In order to prevent any secure data from being released, it is important to test the cryptographic
components of a security module to insure all components are functioning correctly . The router includes
an array of self-tests that are run during startup and periodically during operations. If an y of the self-tests
fail, the router transitions into an er ror state. Within the error state, all secure data transmission is halted
and the router outputs status information indicating the failure.

Note After the router recovers from failure of a power-up self-test performed by the AIM-VPN/EP, the

router only allows plaintext traffic to pass through and no encrypted traffic is allowed.

Self-tests performed by the IOS image:

• Power-up tests

–

Firmware integrity tes t

–

RSA signature KAT (both signature and verification)

–

DES KAT

–

TDES KAT

–

AES KAT

–

Secure Operation of the Cisco 2621XM/2651XM Router

The Cisco 2621XM and 2651XM Modular Access Routers with AIM-VPN/EP meet all the Level 2
requirements for FIPS 140-2. Follow the setting instructions provided below to place the module in FIPS
mode. Operating this router without maintaining the following settings will remove the module from
the FIPS approved mode of operation.

Initial Setup

• The Crypto Officer must ensure that the AIM-VPN/EP crypt ographic accelerator card is installed in

the module by opening the chassis and visual ly confirming the presence of the AIM-VPN/EP. Please
refer to the Cisco publication Installing Adv an ced Integration Modules in Cisco 2600 Series, Cisco
3600 Series, and Cisco 3700 Series Routers for detailed instructions on chassis disassembly and
reassembly, and AIM-VPN/EP identification. This document may be accessed on the web at:

http://www.cisco.com/univercd/cc/td/doc/product/access/acs_mod/cis2600/hw_inst/aim_inst/aims
_ins.pdf

• The Crypto Officer must apply tamper evidence labels as described in the “Physical Security”

section of this document.

• Only a Crypto Officer may ad d and remov e Network Modules. Wh en removing the tamper e viden ce

label, the Crypto Officer should remove the entire label from the router and clean the cover of any
grease, dirt, or oil with an alcohol-based cleaning pad. The Crypto Officer must re-apply tamper
evidence labels on the router as described in the “Physical Security” section of this document.

• Only a Crypto Officer may add and remove WAN Interface Cards. When removing the tamper

evidence label, the Crypto Off icer should remo ve the entire label from the router and clean the cov er
of any grease, dirt, or oil with an alcohol-based cleaning pad. The Crypto Officer must re-apply
tamper evidence labels on the router as described in the “Physical Security” section of this
document.

Secure Operation of the Cisco 2621XM/2651XM Router

• The Crypto Officer must disable IOS Password Recovery by executing the following commands:

configure terminal
no service password-recovery
end
show version

Note Once Password Recovery is disabled, administrative access to the module without the

password will not be possible.

System Initialization and Configuration

• The Crypto Officer must perform the initial configuration. Cisco IOS version 12.3(3d) is the only

allowable image; no other image may be loaded.

• The value of the boot f ield must be 0x0102. This set ting disables break from the console to the R OM

monitor and automatically boots the Cisco IOS image. From the “configure terminal” command
line, the Crypto Officer enters the following syntax:

config-register 0x0102

• The Crypto Officer must create the “enable” password for the Crypto Officer role. The password

must be at least 8 characters and is entered when the Crypto Officer first engages the “enable”
command. The Crypto Officer enters the following syntax at the “#” prompt:

enable secret <PASSWORD>

• The Crypto Officer must always assign passwords (of at least 8 characters) to users. Identification

and authentication on the console port is required for Users. From the “configure terminal”
command line, the Crypto Officer enters the following syntax:

line con 0
password <PASSWORD>
login local

• The Crypto Officer shall only assign users to a privilege level 1 (the default).

• The Crypto Officer shall not assign a command to any privilege level other than its default.

• The Crypto Officer may configure the module to use RADIUS or TACACS+ for authentication.

Configuring the module to use RADIUS or TACACS+ for authentication is optional. If the module
is configured to use RADIUS or TACACS+, the Crypto-Officer must define RADIUS or TACACS+
shared secret keys that are at least 8 characters long.

• If the Crypto Officer loads any IOS image onto the router, this will put the router into a non-FIPS

mode of operation.

IPSec Requirements and Cryptographic Algorithms

• There are two types of key management method that are allowed in FIPS mode: Internet Key

Exchange (IKE) and IPSec manually entered keys.

• Although the Cisco IOS implementation of IKE allows a number of algorithms, only the following

algorithms are allowed in a FIPS 140-2 configuration:

–

ah-sha-hmac

–

esp-des

OL-6262-01

• The following algorithms are not FIPS approved and should be disabled:

Protocols

All SNMP operations must be performed within a secure IPSec tunnel.

Remote Access

• Telnet access to the module is only allowed via a secure IPSec tunnel between the remote system

• SSH access to the module is only allowed if SSH is configured to use a FIPS-approved algorithm.
