3 Architectural Information
Note: The following architectural description is based on the description presented in the
Security Target.
The TOE is comprised of hardware and software and is defined as a distributed TOE
comprising management, or “headend” components (Versa Director, Analytics, and VOS
device configured an SD-WAN controller) and one or many VOS devices operating as data
plane or “Branch” devices. The TOE is a network device with stateful firewall, IDS/IPS, and
VPN gateway capabilities.
3.1 TOE Description
The TOE is a multitenant software platform that delivers software-defined Layer 3 to Layer
7 services with full programmability and automation. The TOE software platform addresses
SD-WAN, SD-Security, and SD-Branch use cases for the WAN edge, delivering multiple
functions in a single, unified software platform.
3.2 TOE Evaluated Platforms
Detail regarding the evaluated configuration is provided in Section 9 below.

3.3 TOE Architecture
The solution consists of the following components:
• Versa Operating SystemTM
(VOSTM
) device—A VOS device is the multiservice
networking and security software platform that provides routing, advanced SD-
WAN, and SD-Security in a single software package. A VOS device is deployed in
the branch, hub, cloud, and data center.
• Versa Director—Versa Director is a centralized provisioning and management
application that allows you to configure, deploy, manage, and orchestrate all your
Versa VOS software instances. Versa Director integrates with third-party operations
and business systems and with cloud management systems by using open and widely
available protocols and API formats.
• Versa Analytics—Versa Analytics is a near real-time analytics engine that provides
historical insights into contextual policy-to-event correlation and visibility based on
application, user, device, and location.
VOS devices, Versa Director, and Versa Analytics can be deployed on Versa appliances—
Cloud Services Gateways1
(CSGs)—and on Versa-certified x86 third-party white box
appliances; in private clouds on hypervisors (KVM and ESXi), and in public clouds (AWS,
Azure, Google Cloud Platform2
).
VOS software consists of a multitenant, single software stack that natively runs multiple
services, such as routing, security, and other network-based functions. These services can be
combined into logical service node groups (SNGs), which can be chained together to deliver
multiple services in a single path. The same software provides the data and control plane
functionality (SD-WAN Controller).
You configure and manage VOS instances through the Versa provisioning and management
platform, Versa Director. VOS devices also generate a variety of audit logs and exports them
to Versa Analytics.
VOS devices provide fully integrated Layer 4 through Layer 7 functions in platform-based
software packages, including OVA, QCOW2, and ISO. VOS devices can be configured to
be a data plane element (SD-Router; SD-WAN; or Secure SD-WAN at a branch, hub, or
gateway) or a control plane element (SD-WAN Controller). VOS software provides a
comprehensive set of built-in services for SD-WAN, basic networking and routing, security
(IPS, Stateful Firewall, NGFW), and VPNs.
Versa Director is a provisioning and management platform that performs the following
functions:
• Centralized single-pane-of-glass configuration, management, and monitoring of the
controllers, branch sites, and hub sites
• Lifecycle management of Versa VOS instances

• System-level high availability (HA) deployed as an active-standby pair for
redundancy
• Staging server during the bootstrapping process
• Virtual network function manager (VNFM)
• Zero-touch provisioning (ZTP) of VOS devices at branch and hub sites
Versa Analytics is an analytics platform that is purpose-built for VOS devices and managed
services. Versa Analytics provides visibility into VOS devices. You can use the analyzed
data to perform baselining, correlation, and prediction about the VOS devices. Versa
Analytics provides real-time and historical data, and you can create reports about usage
patterns, trends, security events, and alerts. Versa Director also provides role-based access
to Versa Analytics.
Branch Versa VOS instances continually provide to Versa Analytics status and quantitative
information about their links, network paths, and services. Additionally, every service
running on a VOS instance, such as NGFW and URL filtering, generates flow-level and
aggregate log messages that are sent to Versa Analytics. Using this information, Versa
Analytics performs a number of functions, including networkwide analysis and optimization,
troubleshooting, trending, capacity planning, dynamic application-based traffic steering, and
security forensics. Versa Analytics passes the results of its analyses to Versa Director.
3.4 Physical Boundaries
On headend components (Director, Analytics, SD-WAN Controller), the boundary surrounds
the entire VM image but excludes the hypervisor and underlying hardware. The VOS Branch
device encompasses the VOS system image and the underlying hardware when deployed as
bare metal, and only the VM image, excluding the hypervisor and hardware, when deployed
as virtual.

6
4.1 Security audit
The TOE provides extensive auditing capabilities by generating an audit record for each
auditable event, thus generating a comprehensive set audit logs that identify specific TOE
operations including audit records for security relevant events.
The TOE can audit events related to identification and authentication, administrative actions,
and activities related to security functionality enforcement.
For each event, the TOE records the date and time of each event, the type of event, the subject
identity, and the outcome of the event.
Audit logs are buffered locally on each component and then forwarded to Analytics for
storage and analysis. Logs are also sent to an external syslog server over a protected IPsec
channel.
4.2 Communications
The TOE is a distributed TOE which uses IPsec for securing all internal communications.
The TOE does not use a registration channel and satisfies all requirements of FTP_ITC.1 for
internal trusted channels. Administrators must manually enable each component before
joining the distributed TOE.
4.3 Cryptographic support
The TOE provides cryptography in support of secure connections, using IPsec for data plane
encryption and IPsec, TLS, SSH, and HTTPS for control plane encryption.
The TOE provides key generation, key destruction and cryptographic operation functions
supported by NIST approved cryptographic algorithms validated under the CAVP.
4.4 User data protection
The TOE ensures residual information is not leaked into subsequent packets by freeing the
contents of packet buffers prior to de-allocation.
4.5 Firewall
The TOE implements a stateful firewall with support for rules covering IPv4, IPv6, TCP,
UDP, and ICMP with optional logging on match, in addition to a baseline of default
processing rules which ensure that the firewall properly rejects malformed packets or other
anomalies.
The TOE also supports processing of dynamic protocols where control and data are
processed on separate ports.

7
4.6 Identification and authentication
All TOE administrative users must be identified and authenticated. Administration may
either be performed locally using the local console CLI or remotely using the web-based GUI
or SSH CLI.
The TOE provides two pre-configured administrative accounts. The TOE requires that users
associated with these accounts be identified and authenticated before permitted access to the
TOE and TOE security functions. Users may authenticate using local password
authentication. The TOE ensures that a minimum password length is supported in addition
to the construction of complex user passwords. Failed authentication attempts will be tracked
and eventually cause the administrator to be locked out until another administrator manually
unlocks the account or after a defined time period elapses.
Pre-shared keys are supported for IPsec connections which may be generated externally or
composed from a password.
X.509 certificates are used in support of IPsec connections (during IKE negotiations).
4.7 Security management
The TOE provides secure administrative services for management of general TOE
configuration and the security functionality provided by the TOE. All TOE administration
occurs either via a local console connection, or through a secure SSH or HTTPS session.
The TOE provides the ability to manage all TOE administrators, all identification and
authentication, all audit functionality of the TOE, all TOE cryptographic functionality,
firewall, IDS/IPS, and VPN gateway functions.
TOE administrators of different roles have different privileges, and the TOE supports pre-
defined administrator roles. By default, the system supports the following administrator
roles, which cannot be deleted or edited: Admin and Operator, (non-admin users will not
have access to the TOE). Admin has super-user privileges and can perform all operations on
the TOE. Operator can perform operations like monitor, check-status, and review
configuration.
4.8 Packet filtering
The TOE supports a packet filtering policy as described in Firewall above.
4.9 Protection of the TSF
The TOE internally maintains the date and time. This date and time are used as the timestamp
that is applied to audit records generated by the TOE. Administrators can synchronize the
system time with the NTP server time via NTP protocol.

8
Additionally, the TOE performs testing of all TSF binaries, cryptographic algorithms, and
entropy sources to ensure correct operation. The TOE will shutdown its interfaces in the
event of a self-test failure to prevent insecure operation.
The TOE will accept software upgrades that have been digitally signed or have been
manually verified by the administrator using a hash prior to installation.
The TOE protects the storage of private keys, passwords and other sensitive data by
restricting file permissions and does not provide any interface which allows exposure of
sensitive plaintext data.
4.10 TOE access
When an administrative session is initially established, the TOE displays an administrator
configurable warning banner. This is used to provide any information deemed necessary by
the administrator.
After a configurable period of inactivity, local and remote administrative sessions will be
terminated, requiring administrators to re-authenticate. Administrators may also manually
terminate their own sessions.
The VPN gateway will provide dynamically assigned IP addresses to endpoints, and
terminate inactive VPN sessions after inactivity. Connections may be restricted based on
security posture, location, and time of day.
4.11 Trusted path/channels
The TOE supports establishing trusted paths between itself and remote administrators using
SSH for CLI access and HTTPS for GUI access. The TOE supports use of IPsec and
HTTPS/TLS for control plane connections, and IPsec for data plane connections (including
distributed TOE channels between VOS Branches and the Versa Headend). The TOE
supports IPsec to encrypt connections with external NTP servers and syslog servers.
4.12 Intrusion Prevention
The TOE supports both in-line and promiscuous inspection modes using both anomaly and
signature-based detection along with IP filtering based on blacklists.

June 2020 (STFFW14e)
• PP-Module for VPN Gateways, Version 1.3, 25 August 2023 (VPNGW13)
That information has not been reproduced here and the NDcPP22e/IPS10/STFFW14e/
VPNGW13 should be consulted if there is interest in that material.
The scope of this evaluation was limited to the functionality and assurances covered in the
NDcPP22e/IPS10/STFFW14e/VPNGW13 as described for this TOE in the Security Target.
Other functionality included in the product was not assessed as part of this evaluation. All
other functionality provided by the devices needs to be assessed separately, and no further
conclusions can be drawn about their effectiveness.
Clarification of scope
All evaluations (and all products) have limitations, as well as potential misconceptions that
need clarification. This text covers some of the more important limitations and clarifications
of this evaluation. Note that:
• As with any evaluation, this evaluation only shows that the evaluated configuration
meets the security claims made with a certain level of assurance (the assurance
activities specified in the collaborative Protection Profile for Network Devices and
the Intrusion Prevention, Firewalls, and VPN Gateways Modules and performed by
the evaluation team).
• This evaluation covers only the specific device models and software as identified in
this document, and not any earlier or later versions released or in process.
• Apart from the Admin Guide, additional customer documentation for the specific
Network Devices, Firewall, IDS/IPS, VPN Gateway models was not included in the
scope of the evaluation and therefore should not to be relied upon when configuring
or operating the device as evaluated.
• This evaluation did not specifically search for, nor attempt to exploit, vulnerabilities
that were not “obvious” or vulnerabilities to objectives not claimed in the ST. The
CEM defines an “obvious” vulnerability as one that is easily exploited with a
minimum of understanding of the TOE, technical sophistication and resources.
• The functionality evaluated is scoped exclusively to the security functional
requirements specified in the NDcPP22e/IPS10/STFFW14e/VPNGW13 and
applicable Technical Decisions. Any additional security related functional
capabilities of the TOE were not covered by this evaluation, including the
functionality listed in Section 6.
