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: - Physical security, commensurate with the value of the TOE and the data it stores or processes, is assumed to be provided by the environment - The Operational Environment is assumed to protect the TOE from direct, public access to its LAN interface - TOE Administrators are trusted to administer the TOE according to site security policies - Authorized Users are trained to use the TOE according to site security policies ### 3.2 Clarification of Scope The TOE incorporates CAVP-validated cryptography and was not subjected to CMVP (FIPS-140) validation. The following Features of the MFP are excluded from the evaluated configuration: 1. **USB Port.** The MFP has a USB Port that is used to directly connect a client computer to the MFP for printing. This USB port is disabled during initial installation and configuration of the TOE. 2. **SD Card Slot.** The MFP has two SD Card Slots, one for customer engineers and one for users. The SD Card Slot for customer engineer is used by customer engineers to install components of the MFP; the SD Card Slot for users is used by users to print documents. Both are disabled when the TOE is operational, a cover is placed on the SD Card slot for customer engineer so cards cannot be inserted or removed and the card slot for users is set to disabled during installation. ## 4 Evaluated Configuration The evaluated configuration consists of the following models running the TOE firmware (JE-1.00-H): - IM C300 - IM C300F - IM 400F - IM 400SRF With support from the operating environment for: - SYSLOG server - LDAP server - NTP server - FTP server - SMTP server ### 4.1 Documentation The following documents are provided to the consumer to assist in the configuration and installation of the TOE: 1.

RICOH IM C300/C300F/C400F/C400SRF Common Criteria Guidance Supplement, v0.6, December 2020 ## 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 of the procedures required to maintain the integrity of the TOE during distribution to the consumer. ## 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 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 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: 1. PP Assurance Activities: The evaluator performed the assurance activities listed in the claimed PP 2. Cryptographic Implementation Verification: The evaluator verified that the claimed cryptographic implementations were present and used by 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. ### 6.4 Independent Penetration Testing The penetration testing effort 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 penetration testing effort. #### 6.4.1 Penetration Test results Type 1 & 2 searches were conducted on 10/16/2020 and included the following search terms: | - RICOH IM C300 - RICOH IM C300F - RICOH IM C400F - RICOH IM C400SRF | - NetBSD 6.0.1 - WolfSSL 3.14.2 - Web Image Monitor version 2.16.1 | |------------------------------------------------------------------------|----------------------------------------------------------------------| Vulnerability searches were conducted using the following sources: | - [https://www.ricoh.com/products/security/mfp/bulletins/](https://www.ricoh.com/products/security/mfp/bulletins/) - [https://www.ricoh.com/info/](https://www.ricoh.com/info/) - NIST National Vulnerabilities Database (can be used to access CVE and US-CERT databases identified below): [https://web.nvd.nist.gov/view/vuln/search](https://web.nvd.nist.gov/view/vuln/search) - Common Vulnerabilities and Exposures: [http://cve.mitre.org/cve/](http://cve.mitre.org/cve/) [https://www.cvedetails.com/vulnerability-search.php](https://www.cvedetails.com/vulnerability-search.php) US-CERT: [http://www.kb.cert.org/vuls/html/search](http://www.kb.cert.org/vuls/html/search) | - Tenable Network Security: [http://nessus.org/plugins/index.php?view=search](http://nessus.org/plugins/index.php?view=search) - Tipping Point Zero Day Initiative: [http://www.zerodayinitiative.com/advisories](http://www.zerodayinitiative.com/advisories) - Offensive Security Exploit Database: [https://www.exploit-db.com/](https://www.exploit-db.com/) - Rapid7 Vulnerability Database: [https://www.rapid7.com/db/vulnerabilities](https://www.rapid7.com/db/vulnerabilities) - Community (Symantec) security community: [https://www.securityfocus.com/](https://www.securityfocus.com/) | |------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| The independent penetration testing did not uncover any residual exploitable vulnerabilities in the intended operating environment. ## 7 Results of the Evaluation This evaluation has provided the basis for the conformance claim documented in Table 1.
