The Cisco Network Convergence System 1004 (NCS1004) is comprised of both software and hardware. The hardware is comprised of NCS1004. The software is comprised of the Universal Cisco Internet Operating System (IOS-XR) software image release IOS-XR 24.1. 3.1 TOE Description The NCS1004 chassis is a 2RU chassis and is the component of the TOE in which all other TOE components are housed. The NCS1004 chassis provides four-line card slots. Each slot can host a 1.2Tbps coherent dense wavelength division multiplexing (DWDM) line card with 12 Quad Small Form-Factor Pluggable (QSFP)-28 based clients and 2 DWDM trunk ports. Each line card can provide up to 12 100Gbe/OTU4 or 3 400GE client ports. The system supports up to 4.8Tbps of client and 4.8Tbps of trunk traffic. The NCS1004 has two redundant and field replaceable AC & DC power supply units and three redundant and field replaceable fans. It also provides a field replaceable controller card and Solid-State Drive (SSD) disks both on-board the chassis and on the controller card for resiliency. For connections to the Syslog audit server, the TOE authenticates those devices with X.509v3 certificates and protects communication channels with the TLS protocol. Secure remote administration is protected with SSH which is implemented with authentication failure handling. 3.2 TOE Evaluated Platforms The evaluated platform consists of the Cisco Network Convergence System 1004 (NCS1004) Running IOS-XR 24.1. 3.3 TOE Architecture The TOE consists of one physical device as specified in section “Physical Boundaries” below and includes the Cisco IOS-XR software. The TOE has two or more network interfaces and is connected to at least one internal and one external network. The Cisco IOS-XR configuration determines how packets are handled to and from the TOE’s network interfaces. The router configuration will determine how traffic flows received on an interface will be handled. Typically, packet flows are passed through the internetworking device and forwarded to their configured destination. An external syslog server must be used to store audit records. For remote administration, a secure session using SSHv2 must be established. Cisco Network Convergence System 1004 Validation Report Version 1.0, March 4, 2025 (NCS1004) Running IOS-XR 24.1 4 3.4 Physical Boundaries The TOE is a hardware and software solution that makes up the router models as follows: NCS1004. The network, on which the TOE resides, is considered part of the IT environment. The TOE is comprised of the following physical specifications: Hardware Platform Processor Software Size Power Interfaces NCS1004 Intel Atom C3758 (Goldmont) IOS-XR 24.1 2RU 3.5 in. x 17.5 in. x 19 in. (8.9 cm x 44.45 cm x 48.26 cm) 1+1 FRU AC or DC <30W per 100G 1300 W (typical) 1400 W (max) 2 (two) slots for 2.1kW AC redundant Power Supply Units (PSU) 3 (three) redundant and field replaceable fans Cisco Network Convergence System 1004 Validation Report Version 1.0, March 4, 2025 (NCS1004) Running IOS-XR 24.1 5 4 Security Policy This section summaries the security functionality of the TOE: 1. Security audit 2. Cryptographic support 3. Identification and authentication 4. Security management 5. Protection of the TSF 6. TOE access 7. Trusted path/channels 4.1 Security audit Auditing allows Security Administrators to discover intentional and unintentional issues with the TOE’s configuration and/or operation. Auditing of administrative activities provides information that may be used to hasten corrective action should the system be configured incorrectly. Security audit data can also provide an indication of failure of critical portions of the TOE (e.g. a communication channel failure or anomalous activity (e.g. establishment of an administrative session at a suspicious time, repeated failures to establish sessions or authenticate to the TOE)) of a suspicious nature. The TOE provides extensive auditing capabilities. The TOE generates an audit record for each auditable event. Each security relevant audit event has the date, timestamp, event description, and subject identity. The TOE provides a circular audit trail. Audit logs are transmitted to an external audit server over a trusted channel protected by TLS. 4.2 Cryptographic support The TOE provides cryptography in support of other TOE security functionality. All the algorithms claimed have CAVP certificates (Operational Environment –Intel Atom). The TOE leverages the Cisco FIPS Object Module 7.3a which resides in the IOS-XR software. The TOE provides cryptography in support of remote administrative management via SSHv2 and secures the session between the NCS1004 and remote syslog server using TLS. 4.3 Identification and authentication The TOE provides authentication services for administrative users wishing to connect to the TOE’s secure CLI administrator interface. The TOE requires Authorized Administrators to authenticate prior to being granted access to any of the management functionality. The TOE can be configured to require a minimum password length of 15 characters as well as mandatory password complexity rules. After a configurable number of incorrect login attempts, the NCS1004 will lock out the account until a configured amount of time for lockout expires. The TOE provides administrator authentication against a local user database. Password- based authentication can be performed on the serial console or SSH interfaces. The SSHv2 interface also supports authentication using SSH keys. Cisco Network Convergence System 1004 Validation Report Version 1.0, March 4, 2025 (NCS1004) Running IOS-XR 24.1 6 The TOE uses X.509v3 certificates as defined by RFC 5280 to support authentication for TLS connections. 4.4 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 through a secure SSHv2 session or via a local console connection. The TOE provides the ability to securely manage all TOE administrative users; all identification and authentication; all audit functionality of the TOE; all TOE cryptographic functionality; the timestamps maintained by the TOE; and updates to the TOE. The TOE supports privileged administrator. Only the privileged administrator can perform the above security relevant management functions. Administrators can create configurable login banners to be displayed at login and can also define an inactivity timeout for each admin interface to terminate sessions after a set period of inactivity. 4.5 Protection of the TSF The TOE protects against interference and tampering by untrusted subjects by implementing identification, authentication, and access controls to limit configuration to Authorized Administrators. The TOE prevents reading of cryptographic keys and passwords. Additionally, Cisco IOS-XR is not a general-purpose operating system and access to Cisco IOS-XR memory space is restricted to only Cisco IOS-XR functions. 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 update the TOE’s clock manually. Finally, the TOE performs testing to verify the correct operation of the router itself and that of the cryptographic module. The TOE can verify any software updates prior to the software updates being installed on the TOE to avoid the installation of unauthorized software. 4.6 TOE access The TOE can terminate inactive sessions after an Authorized Administrator configurable time-period. Once a session has been terminated the TOE requires the user to re-authenticate to establish a new session. The TOE can also display an Authorized Administrator specified banner on the CLI management interface prior to allowing any administrative access to the TOE. 4.7 Trusted path/channels The TOE establishes a trusted path between the appliance and the CLI using SSHv2 and the syslog server using TLS.

Clarification of scope The scope of this evaluation was limited to the functionality and assurances covered in the NDcPP22e as described for this TOE in the ST. 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. 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 NDcPP22e 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 Guides specified in Section 6, additional customer documentation was not included in the scope of the evaluation and, therefore, should not 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 and applicable Technical Decisions. Any additional security related functional capabilities of the TOE were not covered by this evaluation.
