Target of Evaluation
Overview
This chapter contains information about the Target of Evaluation (TOE), including a description of
functionality provided, its architectural components, the scope of evaluation, its security policies and
its secure usage.
Description of the TOE
The TOE is Juniper Networks, Inc. Junos OS 22.4R2 for MX304, EX4100-48MP, EX4100-24MP EX4100-
24P, EX4100-24T and EX4100-48P, EX4100-48T.
The TOE is an Ethernet-optimized edge router with 400-Gbps capacity. It implements both switching
and carrier-class Ethernet routing. The TOE delivers an end-to-end infrastructure security solution for
enterprises looking to move business-critical applications to public clouds. The TOE can be deployed in
campus and branch access layer networks in the EVPN-VXLAN architectures.
The TOE allows definition and enforcement of information flow policies among subnetworks. Each
information flow from one subnetwork to another passes through an instance of the TOE. The TOE
makes a decision, based on the defined policies, whether the traffic is forwarded or dropped.
Forwarding decisions are made on the basis of network addresses and protocols. The TOE also ensures
that security-relevant activity is audited and provides the necessary functions to manage the security
functions.
Each TOE is a secure network device that protects itself by offering only a minimal logical interface to
the network and attached nodes. Junos OS 22.4R2 is a special purpose operating system that provides
no general purpose computing capability. It implements both management and control functions as
well as all IP routing.
The TOE also implements Media Access Control Security (MACsec) encryption and decryption for a
trusted channel at the Data Link Layer.
TOE Functionality
The TOE functionality that was evaluated is described in section 1.6 of the Security Target [7].
TOE physical boundary
The TOE is the complete appliance consisting of the Junos OS 22.4R2 firmware running on the MX304,
EX4100-48MP, EX4100-24MP, EX4100-24P, EX4100-24T, EX4100-48P, EX4100-48T chassis. The TOE
includes an ARM-cortex A72 64-bit, single core processor. The MX304 variant includes an Intel Xeon
D1735-TR CPU. The TOE also includes a line card which implements MACsec. The line card used by the
MX304 variant of the TOE is JNP304-LMIC16.
The install image provided for the TOE is:
 EX4100 variants of the TOE: junos-install-ex-arm-64-22.4R2.8.tgz
 MX304 variant of the TOE: junos-vmhost-install-mx-x86-64-22.4R2.8.tgz
The firmware version reflects the detail reported for the components of the Junos OS when the “show
version” command is executed on the device.
The physical boundary of the MX304, EX4100-48MP, EX4100-24MP, EX4100-24P, EX4100-24T,
EX4100-48P, EX4100-48T devices is shown in the figure below.
8
The TOE interfaces comprise the following:
 network interfaces which control the traffic between the connected subnetworks
 management interface, which handles administrative actions.
Architecture
The TOE consists of the following major architectural components.
The Routing Engine (RE) runs the Junos OS 22.4R2 software and implements Layer 3 routing services
and Layer 2 switching services. The RE also implements a network management interface for the
configuration and operation of the TOE. The RE controls the flow of information through the TOE,
including support for appliance interface control and control plane functions such as chassis
component, system management and user access to the appliance
The Packet Forwarding Engine (PFE) provides all operations necessary for transit packet forwarding.
The RE and the PFE function independently while constantly communicating through a high-speed
internal link. This enables streamlined forwarding and routing control and the capability to run
Internet-scale networks at high speeds.
Power supply bays allow flexibility for provisioning and redundancy. The power supplies distribute the
different output voltages produced by the power supplies to the TOE components depending on their
voltage requirements.
The TOE can be administered using a Command Line Interface (CLI) through the Junos OS. The CLI can
be accessed from a connected terminal console or over a network connection. Management over a
network connection is secured using the SSH protocol. All management accesses require successful
authentication.
The TOE implements EEE 802.1AE conformant MACsec for a Data Link Layer trusted channel between
two instances of the TOE. The MACsec PHYs used by the variants of the TOE are given in the
following:
TOE Variant MACSEC PHY-1 MACSEC PHY-2

Clarification of scope
The evaluation was conducted in accordance with the Common Criteria and associated
methodologies. The scope of the evaluation was limited to those claims made in the Security Target
[7].
Evaluated functionality
Functional tests performed during the evaluation were taken from the Protection Profile and
Supporting Document and sufficiently demonstrate the security functionality of the TOE. Some of the
tests were combined for ease of execution.
Non-TOE hardware/software/firmware
The TOE relies on the provision of the following items in the network environment:
 Syslog server supporting SSHv2 connections to send audit logs
 A Management station with a SSHv2 client for remote administration
 Serial connection client for local administration
Non-evaluated functionality and services
Potential users of the TOE are advised that some functions and services have not been evaluated as
part of the evaluation. Potential users of the TOE should carefully consider their requirements for
using functions and services outside of the evaluated configuration.
Australian Government users should refer to the Australian Government Information Security Manual
[5] for policy relating to using an evaluated product in an unevaluated configuration.
The following components are considered outside of the scope of the TOE:
 use of telnet, since it violates the Trusted Path requirement set
 use of File Transfer Protocol, since it violates the Trusted Path requirement set
 use of Simple Network Management Protocol, since it violates the Trusted Path requirement set
 use of Secure Sockets Layer, including management via J-Web, JUNOScript and JUNOScope,
since it violates the Trusted Path requirement set
 use of Command Line Interface account super-user and linux root account.
10
Security
The CCRA Security Function Policy is a set of rules that defines how information within the TOE is
managed and protected. The Security Target [7] contains a summary of the functionality that is
evaluated.
Usage
Evaluated configuration
The evaluated configuration is based on the default installation of the TOE with additional
configuration implemented from specific guidance instructions. The Common Criteria document for
this evaluation is Junos® OS, Common Criteria Evaluated Configuration Guide for MX304 Device with
JNP304-LMIC16 Line Card, Published 2024-03-28, Release 22.4R2; Junos® OS, Common Criteria
Evaluated Configuration Guide for EX4100 Series Devices, Published 2024-03-27, Release 22.4R2 [6].
Secure delivery
There are several mechanisms provided in the delivery process to ensure that a customer receives a
product that has not been tampered with. The customer should perform the following checks upon
receipt of a device to verify the integrity of the platform:
 shipping label - Ensure that the shipping label correctly identifies the correct customer name and
address as well as the device
 outside packaging - Inspect the outside shipping box and tape. Ensure that the shipping tape has
not been cut or otherwise compromised. Ensure that the box has not been cut or damaged to
allow access to the device
 inside packaging - Inspect the plastic bag and seal. Ensure that the bag is not cut or removed.
Ensure that the seal remains intact.
If the customer identifies a problem during the inspection, they should immediately contact the
supplier providing the order number, tracking number and a description of the identified problem to
the supplier.
Additionally, there are several checks that can be performed to ensure that the customer has received
a box sent by Juniper Networks and not a different company masquerading as Juniper Networks. The
customer should perform the following checks upon receipt of a device to verify the authenticity of
the device:
 verify that the device was ordered using a purchase order. Juniper Networks devices are never
shipped without a purchase order
 when a device is shipped, a shipment notification is sent to the e-mail address provided by the
customer when the order is taken. Verify that this e-mail notification was received and contains
the following information:
 purchase order number
 Juniper Networks order number used to track the shipment
 carrier tracking number used to track the shipment
 list of items shipped including serial numbers
 address and contacts of both the supplier and the customer
 verify that the shipment was initiated by Juniper Network, performing the following tasks:
 compare the carrier tracking number of the Juniper Networks order number listed in the
Juniper Networks shipping notification with the tracking number on the package received
11
 log on to the Juniper Networks online customer support portal at
https://www.juniper.net/customers/csc/management to view the order status
 compare the carrier tracking number or the Juniper Networks order number listed in the
Juniper Networks shipment notification with the tracking number on the package received.
Installation of the TOE
The configuration guides [6] contain all relevant information for the secure configuration of the TOE.
Version verification
The verification of the TOE is largely automatic, including the verification using hashes. The TOE
cannot load a modified image. Valid software images can be downloaded from the
https://www.juniper.net support pages. In addition to the automated verification, the site includes
individual hashes for each image. The administrator should verify the hash of the software before
installing it into the hardware platform.
Security Administrators are able to query the current version of the TOE firmware using the CLI
command ‘show version’.
Documentation and guidance
It is important that the TOE is used in accordance with guidance documentation in order to ensure
secure usage. The following documentation is available to the consumer when the TOE is purchased.
The evaluated configuration guide (system admin guide) document for the MX304 device and EX4100
series devices running Junos OS 22.4R2 is available for download at
https://www.juniper.net/documentation. The documents are: Junos® OS, Common Criteria Evaluated
Configuration Guide for MX304 Device with JNP304-LMIC16 Line Card, Published 2024-03-28, Release
22.4R2; Junos® OS, Common Criteria Evaluated Configuration Guide for EX4100 Series Devices,
Published 2024-03-27, Release 22.4R2 [6].
Common Criteria material is available at https://www.commoncriteriaportal.org.
The Australian Government Information Security Manual is available at https://www.cyber.gov.au/ism
[5].
Secure usage
The evaluation of the TOE took into account certain assumptions about its operational environment.
These assumptions must hold in order to ensure the security objectives of the TOE are met.
The network device is assumed to be physically protected in its operational environment and not
subject to physical attacks that compromise the security and/or interfere with the device’s physical
interconnections and correct operation. This protection is assumed to be sufficient to protect the
device and the data it contains.
The device is assumed to provide networking functionality as its core function and not provide
functionality/services that could be deemed as general purpose computing. For example, the device
should not provide a computing platform for general purpose applications (unrelated to networking
functionality).
The administrator(s) for the network device are assumed to be trusted and to act in the best interest
of security for the organisation. This includes being appropriately trained, following policy and
adhering to guidance documentation. Administrators are trusted to ensure passwords/credentials
have sufficient strength and entropy. The network device is not expected to be capable of defending
against a malicious administrator that actively works to bypass or compromise the security of the
device.
The network device firmware and software is assumed to be updated by an administrator on a regular
basis in response to the release of product updates due to known security vulnerabilities.
12
The administrator’s credentials (private key) used to access the network device are protected by the
platform on which they reside.
The administrator must ensure that there is no unauthorised access possible for sensitive residual
information (e.g. cryptographic keys, keying material, PINs, passwords etc.) on networking equipment
when the equipment is discarded or removed from its operational environment.
13
Evaluation
Overview
This chapter contains information about the procedures used in conducting the evaluation, the testing
conducted as part of the evaluation and the certification result.
Evaluation procedures
The criteria against which the Target of Evaluation (TOE) has been evaluated are contained in the
relevant Protection Profiles [4] and Common Criteria for Information Technology Security Evaluation
Version 3.1 Revision 5, Parts 2 and 3 [1, 2].
Testing methodology was drawn from Common Methodology for Information Technology Security,
April 2017 Version 3.1 Revision 5 [3] and the relevant Supporting Documents [12].
The evaluation was carried out in accordance with the operational procedures of the Australian
Information Security Evaluation Program [10].
In addition, the conditions outlined in the Arrangement on the Recognition of Common Criteria
Certificates in the field of Information Technology Security [9] and the document CC and CEM
addenda, Exact Conformance, Selection-Based SFRs, Optional SFRs [13] were also upheld.
Functional testing
All functional tests performed by the evaluators were taken from the Supporting Documents [12]. The
tests were designed to provide the required testing coverage for the security functions claimed by the
TOE.
Entropy testing
The entropy design description, justification, operation and health tests are assessed and documented
in a separate report [11].
Penetration testing
The evaluators performed the evaluation activities for vulnerability assessment specified by the
collaborative Protection Profile for Network Devices and Protection Profile Module for MACsec
Ethernet Encryption Supporting Documents [12] which follow a flaw hypothesis methodology.
Accordingly, four types of flaw hypotheses have been considered:
 public vulnerabilities
 ND iTC (Network Device international Technical Community) sourced
 evaluation team generated
 tool generated.
Based on the results of this testing, the evaluators determined that the TOE is resistant to an attacker
possessing a basic attack potential.
14
Certification
Overview
This chapter contains information about the result of the certification, an overview of the assurance
provided and recommendations made by the certifiers.
Assurance
This certification is focused on the evaluation of product compliance with Protection Profiles that
cover the technology area of network devices. Organisations can have confidence that the scope of an
evaluation against an ASD-approved Protection Profile covers the necessary security functionality
expected of the evaluated product and known threats will have been addressed.
The analysis is supported by testing as outlined in the Protection Profile Supporting Documents and a
vulnerability survey demonstrating resistance to penetration attackers with a basic attack potential.
Compliance also provides assurance through evidence of secure delivery procedures. Certification is
not a guarantee of freedom from security vulnerabilities.
The effectiveness and integrity of cryptographic functions are also within the scope of product
evaluations performed in line with the Protection Profiles (PPs). PPs provide assurance by providing a
full Security Target, and an analysis of the Security Functional Requirements in that Security Target,
guidance documentation, and a basic description of the architecture of the TOE.
Certification result
Teron Labs has determined that the TOE upholds the claims made in the Security Target [7] and has
met the requirements of the collaborative Protection Profile for Network Devices (CPP_ND) and
Protection Profile Module for Media Access Control Security (PP_MOD_MACsec) [4].
After due consideration of the conduct of the evaluation as reported to the certifiers, and of the
Evaluation Technical Report [8], the Australian Certification Authority certifies the evaluation of
Juniper Junos OS 22.4R2 for MX304 and EX4100-48MP, EX4100-24MP, EX4100-24P, EX4100-24T,
EX4100-48P, EX4100-48T devices performed by the Australian Information Security Evaluation Facility,
Teron Labs.
Recommendations
Not all of the evaluated functionality present in the TOE may be suitable for Australian Government
users. For further guidance, Australian Government users should refer to the Australian Government
Information Security Manual [5].
In addition to ensuring that the assumptions concerning the operational environment are fulfilled, and
the guidance document is followed, the Australian Certification Authority also recommends that users
and administrators:
 ensure that the TOE is operated in the evaluated configuration and that assumptions concerning
the TOE security environment are understood
 configure and operate the TOE according to the vendor’s product administrator guidance and
pay attention to all security warnings
 maintain the underlying environment in a secure manner so that the integrity of the TOE
Security Function is preserved
15
 verify the hash of any downloaded software, as present on the https://www.juniper.net website
 have a system auditor review the audit trail generated and exported by the TOE periodically.
