3 Architectural Information
Note: The following architectural description is based on the description presented in the
Security Target.
The Target of Evaluation (TOE) is the Brocade FastIron SX, ICX, and FCX Series
Switch/Router 08.0.10 family of products.
The TOE is composed of a hardware appliance with embedded software installed on a
management processor. Optionally, a number of co-located appliances can be connected in
order to work as a unit with a common security policy. The embedded software is a version
of Brocades' proprietary Multiservice IronWare software. The software controls the
switching and routing network frames and packets among the connections available on the
hardware appliances.
All TOE appliances are configured at the factory with default parameters to allow
immediate use of the system’s basic features through its Command Line Interface (CLI).
However, the product should be configured in accordance with the evaluated configuration
prior to being placed into operation. The CLI is a text based interface which is accessible
from a directly connected terminal or via a remote terminal using SSH.
The hardware platforms that support the TOE have a number of common hardware
characteristics:
• Central processor that supports all system operations, i.e. PowerPC etc.
• Dynamic memory, used by the central processor for all system operations
• Flash memory, used to store the operating system image
• Non-volatile memory, which stores configuration parameters used to initialize the
system at system startup
• Multiple physical network interfaces either fixed in configuration or removable as
in a chassis based product.
3.1 TOE Evaluated Platforms
The Target of Evaluation (TOE) is the Brocade FastIron SX, ICX, and FCX Series
Switch/Router 08.0.10 including the following series and models:
• SX Series Hardware Platforms (FI-SX-800 and FI-SX-1600),
• ICX Series Hardware Platforms (
o ICX 6610-24, 6610-24F, 6610-24P, 6610-48, 6610-48P,
o ICX 6450-24, 6450-24P, 6450-48, 6450-48P, 6450-C12-PD
o ICX 6650,
Brocade FastIron 08.0.10 Validation Report, Version 1.0

o ICX 7750), and
• FCX Series Hardware Platforms (FCX 624S, FCX 624S-HPOE-ADV, FCX 624-F-
ADV, FCX 648S, and FCX 648S-HPOE-ADV).
3.2 TOE Architecture
The basic architecture of each TOE appliance begins with a hardware appliance with
physical network connections. Within the hardware appliance the Brocade IOS is designed
to control and enable access to the available hardware functions (e.g., program execution,
device access, facilitate basic routing and switching functions). IOS enforces applicable
security policies on network information flowing through the hardware appliance.
The basic start-up operation of the TOE is as follows:
1. At system startup the operating system is transferred from flash memory to dynamic
memory using a built-in hardware bootstrap.
2. The operating system reads the configuration parameters from the configuration file
in non-volatile memory and then builds the necessary data structures in dynamic
memory and begins operation.
During normal operation, IP packets are sent to the management IP address or through the
appliance over one or more of its physical network interfaces, which processes them
according to the system’s configuration and state information dynamically maintained by
the appliance. This processing typically results in the frames or packets being forwarded
out of the device over another interface, or dropped in accordance with a configured policy.
3.3 Physical Boundaries
Each TOE appliance runs a version of the Brocades software and has physical network
connections to its environment to facilitate routing and switching of network traffic. The
TOE appliance can also be the destination of network traffic, where it provides interfaces
for its own management.
The TOE may be accessed and managed through a PC or terminal in the environment
which can be remote from or directly connected to the TOE.
The TOE can be configured to forward its audit records to an external syslog server in the
network environment. This is generally advisable given the limited audit log storage space
on the evaluated appliances.
The TOE can be configured to synchronize its internal clock using an NTP server in the
operational environment.

The use of external authentication services such as RADIUS or TACACS/TACACS+ is
excluded from the evaluated configuration as the FastIron family devices provide no SSL
encryption for external authentication servers
4 Security Policy
This section summaries the security functionality of the TOE:
1. Security audit
2. Cryptographic support
3. User data protection
4. Identification and authentication
5. Security Management
6. Protection of the TSF
7. TOE access
8. Trusted path/channels
4.1 Security audit
The TOE is designed to be able to generate logs for a wide range of security relevant
events. The TOE can be configured to store the logs locally so they can be accessed by an
administrator and also to send the logs to a designated log server using TLS to protect the
logs while in transit on the network.
4.2 Cryptographic support
The TOE includes a FIPS-certified cryptographic module that provides key management,
random bit generation, encryption/decryption, digital signature and secure hashing and key-
hashing features in support of higher level cryptographic protocols including SSH and TLS.
4.3 User data protection
The TOE performs a wide variety of network switching and routing functions, passing
network traffic among its various network connections. While implementing applicable
network protocols associated with network traffic routing, the TOE is carefully designed to
ensure that it doesn’t inadvertently reuse data found in network traffic. This is
accomplished primarily by controlling the size of all buffers, fully overwriting buffer
contents, and zero-padding of memory structures and buffers when necessary.
4.4 Identification and authentication
The TOE requires users to be identified and authenticated before they can use functions
mediated by the TOE, with the exception of passing network traffic in accordance with its
configured switching/routing rules. It provides the ability to both assign attributes (user
names, passwords and privilege levels) and to authenticate users against these attributes.
Brocade FastIron 08.0.10 Validation Report, Version 1.0
May 29, 2014
6
The TOE also provides the authorized administrators with the ability to configure
Authentication Method lists. These lists are used to specify the order in which the
authentication methods are employed whenever there are one or more authentication
methods available.
4.5 Security management
The TOE provides Command Line Interface (CLI) commands to access the wide range of
security management functions to manage its security policies. All administrative activity
and functions including security management commands are limited to authorized users
(i.e., administrators) only after they have provided acceptable user identification and
authentication data to the TOE. The security management functions are controlled through
the use of privileges associated with roles that can be assigned to TOE users. Among the
available privileges, only the Super User can actually manage the security policies provided
by the TOE and the TOE offers a complete set of functions to facilitate effective
management since the Super User allows for complete read-and-write access to the system.
4.6 Protection of the TSF
The TOE implements a number of features design to protect itself to ensure the reliability
and integrity of its security features.
It protects particularly sensitive data such as stored passwords and cryptographic keys so
that they are not accessible even by an administrator. It also provides its own timing
mechanism to ensure that reliable time information is available (e.g., for log
accountability).
Note that the TOE is a single appliance or a closely grouped (e.g., in the same rack)
collection of appliances acting as a unit. As such, no intra-TOE communication is subject
to any risks that may require special protection (e.g., cryptographic mechanisms).
The TOE includes functions to perform self-tests so that it might detect when it is failing. It
also includes mechanisms (i.e., verification of the digital signature of each new image) so
that the TOE itself can be updated while ensuring that the updates will not introduce
malicious or other unexpected changes in the TOE.
4.7 TOE access
The TOE can be configured to display a message of the day banner when an administrator
establishes an interactive session and subsequently will enforce an administrator-defined
inactivity timeout value after which the inactive session (local or remote) will be
terminated.
4.8 Trusted path/channels
The TOE protects interactive communication with administrators using SSHv2 for CLI
access to ensure both integrity and disclosure protection. If the negotiation of an encrypted
Brocade FastIron 08.0.10 Validation Report, Version 1.0

7
session fails or if the user does not have authorization for remote administration, an
attempted connection will not be established.
The TOE protects communication with network peers, such as a log server, using TLS
connections to prevent unintended disclosure or modification of logs.
5 Assumptions
The Security Problem Definition, including the assumptions, may be found in the
Protection Profile for Network Devices, version 1.1, 8 June 2012 (NDPP). That
information has not been reproduced here and the NDPP should be consulted if there is
interest in that material.

During testing, the evaluators identified that failed console login audit records did not
include an userID as required. Brocade created a patch for the missing userID and released
an updated version of the IOS, 08.0.10. The evaluators witnessed testing of the updated
version of the IOS and verified the userID is now included in the audit record. To obtain
the corrected version of the TOE, end users simply need to download version 08.0.10 of the
product. The patched version is the version available to user and older versions have been
deprecated.
