UNCLASSIFIED 1 IDENTIFICATION OF TARGET OF EVALUATION The Target of Evaluation (TOE) is identified as follows: Table 1 TOE Identification TOE Name and Version SonicWall SonicOS Enhanced V6.2.5 VPN Gateway on NSA, SM, and TZ Appliances Developer SonicWall, Inc. Conformance Claim collaborative Protection Profile for Stateful Traffic Filter Firewalls (v1.0, 27-Feb- 2015) 1.1 COMMON CRITERIA CONFORMANCE The evaluation was conducted using the Common Methodology for Information Technology Security Evaluation, Version 3.1 Revision 5, for conformance to the Common Criteria for Information Technology Security Evaluation, Version 3.1 Revision 5. 1.2 TOE DESCRIPTION The TOE is a network appliance that acts as network gateway device that terminate Virtual Private Network (VPN) tunnels. It can be used to provide an authenticated and encrypted path to another site. The TOE supports authentication, and protects data from disclosure or modification during transfer. The VPN functionality is also used to provide a secure connection between the device and the audit server. The firewall capabilities of the TOE include stateful packet inspection. Stateful packet inspection maintains the state of network connections, such as Transmission Control Protocol (TCP) streams and User Datagram Protocol (UDP) communication, traveling across the firewall. The firewall distinguishes between legitimate packets and illegitimate packets for the given network deployment. Only packets adhering to the administrator-configured access rules are permitted to pass through the firewall; all others are rejected. UNCLASSIFIED 1.3 TOE ARCHITECTURE A diagram of the TOE architecture is as follows: Figure 1 TOE Architecture UNCLASSIFIED 2 SECURITY POLICY The TOE implements policies pertaining to the following security functional classes: • Security Audit • Cryptographic Support • User Data Protection • Identification and Authentication • Security Management • Protection of the TSF • TOE Access • Trusted Path/Channels • Stateful Traffic Filtering 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 Government of Canada approved cryptographic algorithms were evaluated by the CAVP and used by the TOE: Table 2 Cryptographic Algorithm(s) Cryptographic Algorithm Standard Certificate Number Advanced Encryption Standard (AES) FIPS 197 #5070 Rivest Shamir Adleman (RSA) FIPS 186-4 #2750 Secure Hash Algorithm (SHS) FIPS 180-3 #4130 Keyed-Hash Message Authentication Code (HMAC) FIPS 198 #3384 Deterministic Random Bit Generation (DRBG) SP 800-90A #1887 Component Validation List SP 800-56A #1631, #1632 Elliptic Curve Digital Signature Algorithm (ECDSA) FIPS 186-4 #951, #1315 UNCLASSIFIED 3 ASSUMPTIONS AND CLARIFICATIONS 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 firewall 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 firewall’s physical interconnections and correct operation. This protection is assumed to be sufficient to protect the firewall and the data it contains. As a result, the cPP will not include any requirements on physical tamper protection or other physical attack mitigations. The cPP will not expect the product to defend against physical access to the firewall that allows unauthorized entities to extract data, bypass other controls, or otherwise manipulate the firewall. • The firewall is assumed to provide networking and filtering functionality as its core function and not provide functionality/services that could be deemed as general purpose computing. For example the firewall should not provide computing platform for general purpose applications (unrelated to networking/filtering functionality). • The authorized administrator(s) for the firewall are assumed to be trusted and to act in the best interest of security for the organization. This includes being 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 firewall. The firewall is not expected to be capable of defending against a malicious administrator that actively works to bypass or compromise the security of the firewall. • The firewall 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. • The administrator’s credentials (private key) used to access the firewall are protected by the host platform on which they reside. • 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. UNCLASSIFIED 3.2 CLARIFICATION OF SCOPE The scope of the evaluation is limited to secure management of the TOE and Stateful Traffic filtering functions. The TOE incorporates CAVP-validated cryptography and was not subjected to CMVP (FIPS-140) validation. The following features/functionality is excluded from this evaluation: • Although SonicWall SonicOS Enhanced v6.2 supports several authentication mechanisms, the following mechanisms are excluded from the evaluated configuration: o Remote Authentication Dial-In User Service (RADIUS) o Lightweight Directory Access Protocol (LDAP) o Active Directory (AD) o eDirectory authentication • Command Line Interface (CLI) (Secure Shell (SSH)) • Application Firewall • Web Content Filtering • Hardware Failover • Real-time Blacklist (Simple Mail Transfer Protocol (SMTP)) • Global Security Client (including Group VPN) • Global Management System • SonicPoint • Voice over IP (VoIP) • Network Time Protocol (NTP) • Antivirus A separate evaluation of the TOE determined that this product satisfies the requirements of the collaborative Protection Profile for Stateful Traffic Filter Firewalls version 1.0 and the extended package for Virtual Private Gateway version 2.1. Results for this evaluation can be found on the Canadian Certified Products list.

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 (SFRs). 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 of the procedures required to maintain the integrity of the TOE during distribution to the consumer. UNCLASSIFIED 6 TESTING ACTIVITIES Testing consists of the following three steps: assessing developer tests, performing independent functional tests, and performing penetration tests. 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 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 FUNCTIONAL TESTING During this evaluation, the evaluator developed independent functional 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; b. Cryptographic module/library verification: The evaluator verified the cryptographic certificates claimed are valid and present in the TOE. 6.3.1 FUNCTIONAL TEST RESULTS The developer’s tests and the independent functional tests yielded the expected results, providing assurance that the TOE behaves as specified in its ST and functional specification. UNCLASSIFIED 6.4 INDEPENDENT PENETRATION TESTING Subsequent to the independent review of public domain vulnerability databases and all evaluation deliverables, limited independent evaluator penetration testing was conducted. The penetration tests focused on: a. Use of automated vulnerability scanning tools to discover potential network, platform and application layer vulnerabilities such as Heartbleed, Shellshock, FREAK, POODLE, and GHOST; and b. Fuzz Testing: The evaluator conducted fuzz testing using unexpected inputs and malformed packets on the TOE interfaces. 6.4.1 PENETRATION TEST RESULTS The independent penetration testing did not uncover any exploitable vulnerabilities in the intended operating environment.
