The TOE claims the following conformance:  collaborative Protection Profile for Network Devices, v2.2e  PP-Module for Virtual Private Network Gateways, v1.1 1.2 TOE DESCRIPTION The Cisco Integrated Services Router is a purpose-built, routing platform that includes Virtual Private Network (VPN) functionality. 1.3 TOE ARCHITECTURE A diagram of the TOE architecture is as follows: TOE Architecture 8 TLP:WHITE UNCLASSIFIED / NON CLASSIFIÉ 2 SECURITY POLICY The TOE implements and enforces policies pertaining to the following security functionality:  Security Audit  Cryptographic Support  Identification and Authentication  Security Management  Packet Filtering  Protection of the TSF  TOE Access  Trusted Path/Channels Complete details of the security functional requirements (SFRs) can be found in the Security Target (ST) referenced in section 8.2. 2.1 CRYPTOGRAPHIC FUNCTIONALITY The following cryptographic implementation is used by the TOE and has been evaluated by the CAVP: Table 2: Cryptographic Implementation Cryptographic Module/Algorithm Certificate Number IOS Common Cryptographic Module (IC2M) C1802 9 TLP:WHITE UNCLASSIFIED / NON CLASSIFIÉ 3 ASSUMPTIONS AND CLARIFICATION OF SCOPE Consumers of the TOE should consider assumptions about usage and environmental settings as requirements for the product’s installation and its operating environment. This will ensure the proper and secure operation of the TOE. 3.1 USAGE AND ENVIRONMENTAL ASSUMPTIONS The following assumptions are made regarding the use and deployment of the TOE:  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.  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).  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).  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).  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. 10 TLP:WHITE UNCLASSIFIED / NON CLASSIFIÉ  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 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.  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. 3.2 CLARIFICATION OF SCOPE The TOE incorporates CAVP-validated cryptography and was not subjected to CMVP (FIPS-140) validation. Only the functionality claimed in the Network Device Collaborative Protection Profile and PP-Module for VPN Gateways was tested. The following functionality is excluded from the evaluation and is disabled in the evaluated configuration:  Operating in Non-FIPS mode  HTTP  SSH (client)  Telnet  TLS 11 TLP:WHITE UNCLASSIFIED / NON CLASSIFIÉ 4 EVALUATED CONFIGURATION The evaluated configuration for the TOE comprises: TOE Software/Firmware Cisco IOS 15.9 with build number v15.9.3M4 TOE Hardware C921-4P, C921J-4P, C926-4P, C927-4P, and C931-4P Environmental Support Radius AAA server, management workstation, local console, certification authority, remote VPN peer, syslog server 4.1 DOCUMENTATION The following documents are provided to the consumer to assist in the configuration and installation of the TOE: a) Cisco 900 Series Integrated Services Routers Software Configuration Guide, June 6, 2019 b) Cisco 900 Series Integrated Services Routers (ISR) Common Criteria Operational User Guidance and Preparative Procedures, v0.8, 20 October 2022 c) Cisco IOS Security Command Reference A to Z, http://www.cisco.com/c/en/us/td/docs/ios- xml/ios/mcl/allreleasemcl/all-book.html 12 TLP:WHITE UNCLASSIFIED / NON CLASSIFIÉ 5 EVALUATION ANALYSIS ACTIVITIES The evaluation analysis activities involved a structured evaluation of the TOE. Documentation and process dealing with Development, Guidance Documents, and Life-Cycle Support were evaluated. 5.1 DEVELOPMENT The evaluators analyzed the documentation provided by the vendor; they determined that the design completely and accurately describes the TOE security functionality (TSF) interfaces and how the TSF implements the security functional requirements. The evaluators determined that the initialization process is secure, that the security functions are protected against tamper and bypass, and that security domains are maintained. 5.2 GUIDANCE DOCUMENTS The evaluators examined the TOE preparative user guidance and operational user guidance and determined that it sufficiently and unambiguously describes how to securely transform the TOE into its evaluated configuration and how to use and administer the product. The evaluators examined and tested the preparative and operational guidance and determined that they are complete and sufficiently detailed to result in a secure configuration. Section 4.1 provides details on the guidance documents. 5.3 LIFE-CYCLE SUPPORT An analysis of the TOE configuration management system and associated documentation was performed. The evaluators found that the TOE configuration items were clearly marked. The evaluators examined the delivery documentation and determined that it described all the procedures required to maintain the integrity of the TOE during distribution to the consumer. 13 TLP:WHITE UNCLASSIFIED / NON CLASSIFIÉ 6 TESTING ACTIVITIES Testing consists of the following three steps: assessing developer tests, performing independent tests, and performing a vulnerability analysis. 6.1 ASSESSMENT OF DEVELOPER TESTS The evaluators verified that the developer has met their testing responsibilities by examining their test evidence, and reviewing their test results, as documented in the Evaluation Test Report (ETR). The correspondence between the tests identified in the developer’s test documentation and the functional specification was complete. 6.2 CONDUCT OF TESTING The TOE was subjected to a comprehensive suite of formally documented, independent functional and penetration tests. The detailed testing activities, including configurations, procedures, test cases, expected results and observed results are documented in a separate Test Results document. 6.3 INDEPENDENT TESTING During this evaluation, the evaluator developed independent functional & penetration tests by examining design and guidance documentation. All testing was planned and documented to a sufficient level of detail to allow repeatability of the testing procedures and results. The following testing activities were performed: a. PP Assurance Activities: The evaluator performed the assurance activities listed in the claimed PP; and b. Cryptographic Implementation Verification: The evaluator verified that the cryptographic implementation was present in the TOE. 6.3.1 INDEPENDENT TESTING RESULTS The developer’s tests and the independent tests yielded the expected results, providing assurance that the TOE behaves as specified in its ST and functional specification. 14 TLP:WHITE UNCLASSIFIED / NON CLASSIFIÉ 6.4 VULNERABILITY ANALYSIS The vulnerability analysis focused on 4 flaw hypotheses.  Public Vulnerability based (Type 1)  Technical community sources (Type 2)  Evaluation team generated (Type 3)  Tool Generated (Type 4) The evaluators conducted an independent review of all evaluation evidence, public domain vulnerability databases and technical community sources (Type 1 & 2). Additionally, the evaluators used automated vulnerability scanning tools to discover potential network, platform, and application layer vulnerabilities (Type 4). Based upon this review, the evaluators formulated flaw hypotheses (Type 3), which they used in their vulnerability analysis. Type 1 & 2 searches were conducted on 19 September 2022 and included the following search terms: ISR900 C921-4P ISR900 C921J-4P ISR900 C926-4P ISR900 C927-4P ISR900 C931-4P Intel Atom C3558 processor IOS 15.9 operating system IC2Mrel5 OpenSSH - 1:5.5p1 ACT2Lite Vulnerability searches were conducted using the following sources: Vendor security advisories https://tools.cisco.com/security/center/publicationListing.x CISA Known Exploited Vulnerabilities Catalog https://www.cisa.gov/known-exploited-vulnerabilities- catalog NIST National Vulnerabilities Database https://web.nvd.nist.gov/view/vuln/search Common Vulnerabilities and Exposures: http://cve.mitre.org/cve/ https://www.cvedetails.com/vulnerability-search.php US-CERT http://www.kb.cert.org/vuls/html/search Offensive Security Exploit Database https://www.exploit-db.com/ Rapid7 Vulnerability Database https://www.rapid7.com/db/vulnerabilities 6.4.1 VULNERABILITY ANALYSIS RESULTS The vulnerability analysis did not uncover any security relevant residual exploitable vulnerabilities in the intended operating environment. 15 TLP:WHITE UNCLASSIFIED / NON CLASSIFIÉ 7 RESULTS OF THE EVALUATION The Information Technology (IT) product identified in this certification report, and its associated certificate, has been evaluated at an approved testing laboratory established under the Canadian Centre for Cyber Security.
