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 22.2R1 for SRX380 services gateway appliance.
The Services Gateway appliance primarily supports the definition and enforcement of information
flow policies among network nodes. The Services Gateway appliance provides for stateful inspection
of every packet that traverses the network and provides central management to manage the network
security policy. All information flow from one network node to another passes through an instance of
the TOE. Information flow is controlled on the basis of network node addresses, protocol, type of
access requested, and services requested. In support of the information flow security functions, the
TOE ensures that security-relevant activity is audited, that its own functions are protected from
potential attacks, and provides the security tools to manage all of the security functions. The TOE
provides multi-site virtual private network (VPN) gateway functionality. The TOE also implements
Intrusion Prevention System (IPS) functionality, capable of monitoring information flows to detect
potential attacks based on pre-defined attack signature and anomaly characteristics in the traffic.
The appliance has been evaluated in the typical standalone mode and in cluster mode. In cluster
mode a pair of devices are connected together and configured to operate like a single device to
provide high availability. When configured as a cluster, the two nodes back up each other, with one
node acting as the primary device and the other as the secondary device, ensuring stateful failover of
processes and services in the event of system or hardware failure. If the primary device fails, the
secondary device takes over processing of traffic.
The SRX Services Gateway appliance runs the Juniper Networks Junos operating system (Junos OS),
Junos OS 22.2R1.
The appliance is physically self-contained, housing the software, firmware and hardware necessary to
perform all router functions. The hardware consists of the Services Gateway appliance itself and
various generic network media adaptors which allow the appliance to communicate with the different
types of networks that may be required.
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 Junos OS 22.2R1 firmware running on the SRX380 as listed in the table below. The TOE
is contained within the physical boundary of the SRX380.
Chassis Model Networking Ports
SRX380  Four Mini PIM slots
8
 Sixteen 1Gb Ethernet RJ45 ports
 Four 10Gb SFP+ ports
 One console (RJ45 serial + mini-USB) port
 One Management RJ45 port
In the SRX380 the sixteen 1Gb RJ45 and four 10Gb SFP+ ports support MACsec.
Abbreviations:
IOC Input / Output Card
Mini-PIM Mini Physical Interface Module
mini-USB mini Universal Serial Bus
RJ45 8-pin copper connection
SFP+ enhanced Small Form factor Pluggable
More information on the mini-PIM slots for the Juniper SRX380 is available in the Security Target [7]
and the Juniper web site.
The jinstall image provided for the TOE is:
 junos-srxsme-22.2R1.9.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 for the SRX380 model is shown in the figure below.
The TOE interfaces comprise the following:
 network interfaces which pass traffic
 management interface which handles administrative actions.
9
Architecture
The TOE consists of the following two major architectural components.
The Routing Engine (RE) runs the Junos firmware and provides Layer 3 routing services and network
management for all operations necessary for the configuration and operation of the TOE. The RE also
controls the flow of information through the TOE, including Network Address Translation (NAT) and all
operations necessary for the encryption/decryption of packets for secure communication via the IPSec
protocol.
The Packet Forwarding Engine (PFE) provides all operations necessary for transit packet forwarding.
The Routing Engine and Packet Forwarding Engine perform their primary tasks independently, while
constantly communicating through a high-speed internal link. This arrangement provides streamlined
forwarding and routing control and the capability to run Internet-scale networks at high speeds.
The functions of the TOE can all be managed through the Junos firmware, either from a connected
terminal console or via a network connection. All management, whether from a user connecting to a
terminal or from the network, requires successful authentication. In the evaluated deployment the
TOE is managed and configured via Command Line Interface, either via a directly connected console or
over the network secured using the SSH protocol.
The MACsec line cards support MACsec between adjacent devices, all traffic communicated between
the devices including frames for LLDP, DHCP, ARP, STP, Ethernet Control frames, etc. In the evaluated
configuration MACsec must be configured individually on each point-to-point Ethernet link, such that
a pair of MACsec devices (connected by a physical medium) protect Ethernet frames switched or
routed from one device to the other.
To operate in high availability cluster mode the TOE must be paired with another identically
configured TOE instance as shown in the diagram below. The secondary (shadow) TOE is invisible to
the Zone 1 and Zone 2 networks until it is required to replace the previously active primary TOE and
become the new active TOE. The state sync activities of the primary TOE required to maintain cluster
mode place a strain on the primary TOE that makes this mode different to standalone mode. This is
noticeable during TOE management activities as some commands take longer to complete.

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 Profiles and
Supporting Documents 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
 SSHv2 client for remote administration
 serial connection client for local administration
 MACsec enabled peers
 IPsec enabled peers.
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.
11
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 Junos root account.
Security
The TOE Security 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 Guide for SRX300, SRX320, SRX340, SRX345, SRX345-
DUAL-AC and SRX380 Devices, Release 22.2R1, 2022-11-21 [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
12
 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
 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 guide [6] contains 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 SRX380 running Junos OS
22.2R1 is available for download at https://www.juniper.net/documentation. The document is: Junos
OS, Common Criteria Guide for SRX300, SRX320, SRX340, SRX345, SRX345-DUAL-AC and SRX380
Devices, Release 22.2R1, 2022-11-21.
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].
13
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.
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.
It is assumed that the TOE is connected to distinct networks in a manner that ensures that the TOE
security policies will be enforced on all applicable network traffic flowing among the attached
networks.

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.a – 4.e] 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], the relevant Supporting Documents [12.a – 12.d] and Extended
Package [4.e].
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 draft 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 Protection Profiles [4] and
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 Supporting Document [12.a] which follow a flaw
hypothesis methodology. In addition, the PP-Module for VPN Gateways Supporting Document [12.d]
provides extra search term information for generating public vulnerability based flaw hypotheses.
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.
15
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 with added security functionality including stateful
traffic firewall functions, VPN gateway functions, intrusion prevention functions and MACsec
encryption. 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 Protection Profiles CPP_ND [4.a], MOD_IPS [4.b], MOD_CPP_FW [4.c],
MOD_VPNGW [4.d] and MACsecEP [4.e].
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 22.2R1 for SRX380 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:
16
 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
 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.
