3 Security Problem Definition
15 The Security Problem Definition is reproduced from section 4 of the NDcPP.
3.1 Threats
Table 6: Threats
Identifier Description
T.UNAUTHORIZED_
ADMINISTRATOR_
ACCESS
Threat agents may attempt to gain Administrator access to the
Network Device by nefarious means such as masquerading as an
Administrator to the device, masquerading as the device to an
Administrator, replaying an administrative session (in its entirety, or
selected portions), or performing man-in-the-middle attacks, which
would provide access to the administrative session, or sessions
between Network Devices. Successfully gaining Administrator access
allows malicious actions that compromise the security functionality of
the device and the network on which it resides.
T.WEAK_
CRYPTOGRAPHY
Threat agents may exploit weak cryptographic algorithms or perform a
cryptographic exhaust against the key space. Poorly chosen
encryption algorithms, modes, and key sizes will allow
attackers to compromise the algorithms, or brute force exhaust the key
space and give them unauthorized access allowing them to read,
manipulate and/or control the traffic with minimal effort.
T.UNTRUSTED_
COMMUNICATION_
CHANNELS
Threat agents may attempt to target Network Devices that do not use
standardized secure tunnelling protocols to protect the critical network
traffic. Attackers may take advantage of poorly designed protocols or
poor key management to successfully perform man-in-the-middle
attacks, replay attacks, etc. Successful attacks will result in loss of
confidentiality and integrity of the critical network traffic, and potentially
could lead to a compromise of the Network Device itself.
T.WEAK_
AUTHENTICATION_
ENDPOINTS
Threat agents may take advantage of secure protocols that use weak
methods to authenticate the endpoints – e.g. a shared password that
is guessable or transported as plaintext. The consequences are the
same as a poorly designed protocol, the attacker could masquerade
as the Administrator or another device, and the attacker could insert
themselves into the network stream and perform a man-in-the-middle
attack. The result is the critical network traffic is exposed and there
could be a loss of confidentiality and integrity, and potentially the
Network Device itself could be compromised.
T.UPDATE_
COMPROMISE
Threat agents may attempt to provide a compromised update of the
software or firmware which undermines the security functionality of the
device. Non-validated updates or updates validated using non-secure
or weak cryptography leave the update firmware vulnerable to
surreptitious alteration.
T.UNDETECTED_
ACTIVITY
Threat agents may attempt to access, change, and/or modify the
security functionality of the Network Device without Administrator
awareness. This could result in the attacker finding an avenue (e.g.,
misconfiguration, flaw in the product) to compromise the device and
Keysight Technologies Security Target
Page 14 of 46
Identifier Description
the Administrator would have no knowledge that the device has been
compromised.
T.SECURITY_
FUNCTIONALITY_
COMPROMISE
Threat agents may compromise credentials and device data enabling
continued access to the Network Device and its critical data. The
compromise of credentials includes replacing existing credentials with
an attacker’s credentials, modifying existing credentials, or obtaining
the Administrator or device credentials for use by the attacker.
T.PASSWORD_
CRACKING
Threat agents may be able to take advantage of weak administrative
passwords to gain privileged access to the device. Having privileged
access to the device provides the attacker unfettered access to the
network traffic, and may allow them to take advantage of any trust
relationships with other Network Devices.
T.SECURITY_
FUNCTIONALITY_
FAILURE
An external, unauthorized entity could make use of failed or
compromised security functionality and might therefore subsequently
use or abuse security functions without prior authentication to access,
change or modify device data, critical network traffic or security
functionality of the device.
3.2 Assumptions
Table 7: Assumptions
Identifier Description
A.PHYSICAL_
PROTECTION
The Network Device is assumed to be physically protected in its
operational environment and not subject to physical attacks that
compromise the security 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. As a result,
the cPP does not include any requirements on physical tamper
protection or other physical attack mitigations. The cPP does not
expect the product to defend against physical access to the device
that allows unauthorized entities to extract data, bypass other controls,
or otherwise manipulate the device. For vNDs, this assumption applies
to the physical platform on which the VM runs.
A.LIMITED_
FUNCTIONALITY
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).
In the case of vNDs, the VS is considered part of the TOE with only
one vND instance for each physical hardware platform. The exception
being where components of the distributed TOE run inside more than
one virtual machine (VM) on a single VS. There are no other guest
VMs on the physical platform providing non-Network Device
functionality.
Keysight Technologies Security Target
Page 15 of 46
Identifier Description
A.NO_THRU_
TRAFFIC_
PROTECTION
A standard/generic Network Device does not provide any assurance
regarding the protection of traffic that traverses it. The intent is for the
Network Device to protect data that originates on or is destined to the
device itself, to include administrative data and audit data. Traffic that
is traversing the Network Device, destined for another network entity,
is not covered by the NDcPP. It is assumed that this protection will be
covered by cPPs and PP-Modules for particular types of Network
Devices (e.g., firewall).
A.TRUSTED_
ADMINISTRATOR
The Security Administrator(s) for the Network Device are assumed to
be trusted and to act in the best interest of security for the
organization. This includes appropriately trained, following policy, and
adhering to guidance documentation. Administrators are trusted to
ensure passwords/credentials have sufficient strength and entropy and
to lack malicious intent when administering the device. 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.
For TOEs supporting X.509v3 certificate-based authentication, the
Security Administrator(s) are expected to fully validate (e.g. offline
verification) any CA certificate (root CA certificate or intermediate CA
certificate) loaded into the TOE’s trust store (aka ‘root store’, ‘ trusted
CA Key Store’, or similar) as a trust anchor prior to use (e.g. offline
verification).
A.REGULAR_
UPDATES
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 vulnerabilities.
A.ADMIN_
CREDENTIALS_
SECURE
The Administrator’s credentials (private key) used to access the
Network Device are protected by the platform on which they reside.
A.RESIDUAL_
INFORMATION
The Administrator must ensure that there is no unauthorized 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.
3.3 Organizational Security Policies
Table 8: Organizational Security Policies
Identifier Description
P.ACCESS_BANNER The TOE shall display an initial banner describing restrictions of use,
legal agreements, or any other appropriate information to which users
consent by accessing the TOE.
Keysight Technologies Security Target

4 Security Objectives
16 The security objectives are reproduced from section 5 of the NDcPP.
Table 9: Security Objectives for the Operational Environment
Identifier Description
OE.PHYSICAL Physical security, commensurate with the value of the TOE and the
data it contains, is provided by the environment.
OE.NO_GENERAL_
PURPOSE
There are no general-purpose computing capabilities (e.g., compilers
or user applications) available on the TOE, other than those services
necessary for the operation, administration and support of the TOE.
OE.NO_THRU_
TRAFFIC_
PROTECTION
The TOE does not provide any protection of traffic that traverses it. It
is assumed that protection of this traffic will be covered by other
security and assurance measures in the operational environment.
OE.TRUSTED_ADMIN Security Administrators are trusted to follow and apply all guidance
documentation in a trusted manner. For vNDs, this includes the VS
Administrator responsible for configuring the VMs that implement ND
functionality.
For TOEs supporting X.509v3 certificate-based authentication, the
Security Administrator(s) are assumed to monitor the revocation status
of all certificates in the TOE’s trust store and to remove any certificate
from the TOE’s trust store in case such certificate can no longer be
trusted.
OE.UPDATES The TOE firmware and software is updated by an Administrator on a
regular basis in response to the release of product updates due to
known vulnerabilities.
OE.ADMIN_
CREDENTIALS_
SECURE
The Administrator’s credentials (private key) used to access the TOE
must be protected on any other platform on which they reside.
OE.RESIDUAL_
INFORMATION
The Security Administrator ensures that there is no unauthorized
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.

source that provides a minimum of 256 bits of entropy. Additional detail is provided
the proprietary Entropy Description.
6.2.11 FCS_TLSC_EXT.1 & FCS_TLSC_EXT.2
49 The TOE operates as a TLS client for the trusted channels with syslog and LDAP
servers.
50 TLS 1.2 is allowed and ciphersuites are restricted to the following:
a) TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 as defined in RFC 5289
Keysight Technologies Security Target
Page 36 of 46
b) TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA as defined in RFC 4492
51 Ciphersuites are not user-configurable.
52 The TOE supports 2-way certificate authentication with X.509v3 certificates for
Syslog communication. Only DNS names are supported as acceptable reference
identifiers. For server certificate verification, the TOE compares the reference
identifiers to the identifier in the presented server’s TLS certificate.
53 When the TLS client receives an X.509 certificate from the server, the client will
compare the reference identifier with the established Subject Alternative Names
(SANs) in the certificate. If a SAN is available and does not match the reference
identifier, then the verification fails and the channel is terminated. If there are no
SANs of the correct type (DNS name) in the certificate, then the TOE will compare
the reference identifier to the Common Name (CN) in the certificate Subject. If there
is no CN, then the verification fails and the channel is terminated. If the CN exists
and does not match, then the verification fails and the channel is terminated.
Otherwise, the reference identifier verification passes and additional verification
actions can proceed.
54 The TLS client does not support certificate pinning. Only Syslog Communication
supports wildcards.
55 The TLS client will transmit the Supported Elliptic Curves extension in the Client
Hello message by default with support for the following NIST curves: P256, P384,
P521. The non-TOE server can choose to negotiate the elliptic curve from this set
for any of the mutually negotiable elliptic curve ciphersuites.
6.2.12 FCS_TLSS_EXT.1
56 The TOE operates as a TLS server for the web GUI/WebAPI trusted path.
57 The server only allows TLS protocol version1.2 (rejecting any other protocol version,
including SSL 2.0, SSL 3.0, TLS 1.0 and TLS 1.1 and any other unknown TLS
version string supplied) and is restricted to the following ciphersuites by default:
a) TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 as defined in RFC 5289
b) TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA as defined in RFC 4492
58 Ciphersuites are not user-configurable.
59 The TLS server is capable of negotiating ciphersuites that include ECDHE key
agreement schemes. The TLS server supports NIST curves P256, P384, P521.
60 The TOE supports session resumption based on session IDs according to RFC
5246. When a connection is established by resuming a session, new
ClientHello.random and ServerHello.random values are hashed with the session's
master_secret. Sessions cannot be resumed unless both the client and server
agree.
6.3 Identification and Authentication
6.3.1 FIA_PMG_EXT.1
61 The TOE supports the local definition of users with corresponding passwords. The
passwords can be composed of any combination of upper and lower case letters,
numbers, and special characters “!”, “@”, “#”, “$”, “%”, “^”, “&”, “*”, “(“, “)”, “`”, ”~”, ”_”,
”+”, ”-“, ”=”, ”{“, ”}”, “|”, “\”, “:”, “””, ”;”, ”’”, “<”, “>”, “?”, “,”, “.”, “/”, “[”, ”]”.
62 The minimum password length is settable by the Administrator and can range from
15 to 100 characters.
Keysight Technologies Security Target
Page 37 of 46
6.3.2 FIA_UIA_EXT.1
63 The TOE requires all users to be successfully identified and authenticated. The
following actions may occur prior to authentication:
a) Display the warning banner
b) Access to help files (PDF and html format)
c) View alarm notifications (i.e. system health alarms)
d) View software version number
64 Administrative access to the TOE is facilitated through:
a) Local. Directly connecting to the TOE via the Serial Console
b) Web GUI. Remotely connecting to the TOE web GUI/WebAPI via HTTPS
6.3.3 FIA_UAU_EXT.2
65 Regardless of the interface at which the administrator interacts, the TOE prompts the
user for a credential. Only after the administrative user presents the correct
authentication credentials will they be granted access to the TOE administrative
functionality. No TOE administrative access is permitted until an administrator is
successfully identified and authenticated.
66 The TOE provides a local password-based authentication mechanism.
67 The TOE supports local authentication for each management interface.
Authentication is successful when the submitted username and password are
verified against stored values.
6.3.4 FIA_UAU.7
68 For all authentication at the local Serial Console the TOE displays only bullets when
the administrative password is entered so that the password is obscured.
6.3.5 FIA_AFL.1
69 The TOE is capable of tracking authentication failures of remote administrators.
70 When a user account has sequentially failed authentication the configured number of
times (default 3), the account will be locked until a System Administrator performs
unlocks the account.
71 The administrator can configure the maximum number of failed attempts for users
authenticating to either web GUI/WebAPI or Serial Console. The default
administrative account cannot be locked and is limited to the serial console in the
evaluated configuration.
6.3.6 FIA_X509_EXT.1/Rev
72 The TOE performs X.509 certificate validation at the following points:
a) TOE TLS client validation of server X.509 certificates;
b) When certificates are loaded into the TOE, such as when importing CAs,
certificate responses and other device-level certificates
73 In all scenarios, certificates are checked for several validation characteristics:
a) If the certificate ‘notAfter’ date is in the past, then this is an expired certificate
which is considered invalid;
Keysight Technologies Security Target
Page 38 of 46
b) The certificate chain must terminate with a trusted CA certificate;
c) Server certificates consumed by the TOE TLS client must have a
‘serverAuthentication’ extendedKeyUsage purpose;
d) The TOE validates a certificate path and treats a certificate as a CA certificate
when certificates include the basicConstraints extensions and that the CA flag
is set to “TRUE” for all CA certificates.
74 Certificate revocation checking for the above scenarios is performed using a CRL.
75 The TOE does not provide X.509 Certificate Validation on trusted updates, firmware
integrity self-tests or client authentication, the code-signing and clientAuthentication
purpose is not checked in the extendedKeyUsage for related certificates.
76 The TOE ensures that the X.509 certificates adhere to RFC 5280 Section 6.3
(certificate validation and certificate path validation), which can be summarized as
follows:
a) The public key algorithm and parameters are checked
b) The current date/time is checked against the validity period revocation status
is checked
c) Issuer name of X matches the subject name of X+1
d) Name constraints are checked
e) Policy OIDs are checked
f) Policy constraints are checked; issuers are ensured to have CA signing bits
g) Path length is checked
h) Critical extensions are processed
77 If, during the entire trust chain verification activity, any certificate under review fails a
verification check, then the entire trust chain is deemed untrusted.
6.3.7 FIA_X509_EXT.2
78 The TOE has a trust store where root CA and intermediate CA certificates can be
stored. The trust store is not cached: if a certificate is deleted, it is immediately
untrusted. If a certificate is added to the trust store, it is immediately trusted for its
given scope.
79 Instructions for configuring the trusted IT entities to supply appropriate X.509
certificates are captured in the guidance documents.
80 As part of the verification process, a CRL is used to determine whether the certificate
is revoked or not. If the CRL cannot be obtained, the validation will fail.
6.3.8 FIA_X509_EXT.3
81 The TOE supports the generation of Certificate Request Messages as specified by
RFC 2986 and validates the chain of certificates from the root CA upon receiving the
CA Certificate Response. Certificate Request Messages provided by the TOE
include the following information in the request:
a) Public key
b) Common Name (CN)
c) Organization (O)
d) Organizational Unit (OU)

presented with the update option.
6.4.2 FMT_MOF.1/Functions
83 The TOE restricts the ability to modify (enable/disable) transmission of audit records
to an external audit server to Security Administrators.
6.4.3 FMT_MTD.1/CoreData
84 Users are required to login, no TOE functionality is available before identification and
authentication occurs.
6.4.4 FMT_MTD.1/CryptoKeys
85 The TOE restricts generation, importation, or deletion of cryptographic keys. to
Security Administrators.
6.4.5 FMT_SMF.1
86 The TOE may be managed via the Serial Console or GUI/WebAPI (HTTPS). The
specific management capabilities include:
a) Ability to administer the TOE locally via Serial Console and remotely via web
GUI/WebAPI

GUI/WebAPI
g) Ability to configure NTP time sources through web GUI/WebAPI
h) Ability to manage the cryptographic keys, including import and management of
X.509v3 certificates via web GUI/WebAPI
6.4.6 FMT_SMR.2
87 The TOE implements role-based access control based on pre-defined profiles that
are assigned when creating a user.
88 Management of TSF data via the Serial Console or Web GUI/WebAPI is restricted to
Security Administrators.

6.5.3 FPT_TST_EXT.1
91 At startup, the TOE performs the following tests:
Keysight Technologies Security Target
Page 41 of 46
a) Firmware integrity test using CRC32
b) Configuration integrity test using HMAC SHA-256
c) Algorithm Known Answer Tests
d) DRBG health checks: instantiate, un-instantiate, generate, and reseed
e) Boot loader image verification – the boot loader verifies the SHA256 hash of
file “mss-upgrade-components.bin” before the software is installed. Before the
“mss-upgrade-components.bin” file is decrypted, the SHA256 hash value will
be verified
92 The TOE performs this suite of FIPS power-up and conditional self-tests to verify its
correct operation. If any of the self-tests fail, the TOE enters into a critical error state
and the appliance must be rebooted by an administrator to run the tests again.
93 The cryptographic module executes the following conditional tests when the related
service is invoked:
a) Continuous NDRNG test
b) Continuous DRBG test
c) RSA pairwise consistency test
d) Configuration integrity test using HMAC SHA-256
e) Firmware load test with 2048-bit RSA key
6.5.4 FPT_TUD_EXT.1
94 The current firmware version may be queried using GUI/WebAPI.
95 Digitally signed (RSA 2048) upgrade tar files are acquired by contacting Keysight
Technical Support or downloaded via a Customer Portal. Only authorized
administrators can perform manual software upgrades.
96 When the administrator performs the software upgrade, the TOE verifies the digital
signature of the upgrade files using a hardcoded RSA 2048-bit public key.
97 If the digital signature verification fails, the update is aborted, and a log is generated.
98 Upon successful verification, the TOE software extracts the upgrade components
from the tar file and performs the software upgrade. After the software is installed,
the TOE is automatically restarted and requires the administrator to log in again for
the upgrade process to be complete. If the newly installed software fails for any
reason, the TOE software reverts to the previous version without loss of functionality.
6.5.5 FPT_STM_EXT.1
99 The TOE uses external NTP servers to synchronize the clock and provide reliable
timestamps for syslog messages.
100 The TOE provides reliable time stamps for the following:
a) Security Audit functionality
b) Track the inactivity of administrative sessions
c) Cryptographic functions
Keysight Technologies Security Target

on a specified time period of inactivity configured by a Security Administrator.
6.6.2 FTA_SSL.3
102 The Security Administrator may configure the TOE to terminate an inactive remote
interactive session following a specified period of time.
6.6.3 FTA_SSL.4
103 Administrative users are allowed to terminate their own interactive sessions by
logging out.
6.6.4 FTA_TAB.1
104 The TOE displays an administrator configurable message to users prior to login at
the Serial Console and Web GUI.
105 Note: The Web API is not interactive and does not display a banner.
6.7 Trusted Path/Channels
6.7.1 FTP_ITC.1
106 The TOE supports secure communication with the following IT entities:
a) TLS v1.2 for connections to the Syslog server
b) TLS v1.2 for connections to the LDAP Authentication Server
6.7.2 FTP_TRP.1/Admin
107 The TOE provides the following trusted paths for remote administration:

interactive session after a specified period of inactivity. It is the only component of this family.
Management: FTA_SSL_EXT.1
The following actions could be considered for the management functions in FMT:
c) Specification of the time of user inactivity after which lock-out occurs for an
individual user.
Audit: FTA_SSL_EXT.1
The following actions should be auditable if FAU_GEN Security audit data generation is
included in the PP/ST:
b) Any attempts at unlocking an interactive session.

Hierarchical to: No other components
Dependencies: FIA_UAU.1 Timing of authentication
FTA_SSL_EXT.1.1 The TSF shall, for local interactive sessions, [selection:
• lock the session -disable any activity of the Administrator’sdata access/displaydevices
other than unlocking the session, and requiring that the Administrator re-authenticate
to the TSF prior to unlocking the session;
• terminate the session]
after a Security Administrator-specified time period of inactivity.
C.6 Communication (FCO)
C.6.1 Communication Partner Control (FCO_CPC_EXT)
Family Behaviour
This family is used to define high-level constraints on the ways that partner IT entities
communicate. For example, there may be constraints on when communication channels can be
used, how they are established, and links to SFRs expressing lower-level security properties of
the channels.
Component levelling
FCO_CPC_EXT.1 Component Registration Channel Definition, requires the TSF to support a
registration channel for joining together components of a distributed TOE, and to ensure that
the availability of this channel is under the control of an Administrator. It also requires
statement of the type of channel used (allowing specification of further lower-level security
requirements by reference to other SFRs).
Management: FCO_CPC_EXT.1
No separate management functions are required. Note that elements of the SFR already specify
certain constraints on communication in order to ensure that the process of forming a
distributed TOE is a controlled activity.
Audit: FCO_CPC_EXT.1
The following actions should be auditable if FCO_CPC_EXT.1 is included in the PP/ST:

a) Enabling communications between a pair of components as in FCO_CPC_EXT.1.1
(including identities of the endpoints).
b) Disabling communications between a pair of components as in FCO_CPC_EXT.1.3
(including identity of the endpoint that is disabled).
If the required types of channel in FCO_CPC_EXT.1.2 are specified by using other SFRs then
the use of the registration channel may be sufficiently covered by the audit requirements on
those SFRs: otherwise a separate audit requirement to audit the use of the channel should be
identified for FCO_CPC_EXT.1.

Hierarchical to: No other components.
Dependencies: No other components.
FCO_CPC_EXT.1.1 The TSF shall require a Security Administrator to enable
communications between any pair of TOE components before such communication can take
place.
FCO_CPC_EXT.1.2 The TSF shall implement a registration process in which components
establish and use a communications channel that uses [assignment: list of different types of
channel given in the form of a selection] for at least [assignment: type of data for which the
channel must be used].
FCO_CPC_EXT.1.3 The TSF shall enable a Security Administrator to disable
communications between any pair of TOE components.
