UNCLASSIFIED 7 TLP:WHITE 1 IDENTIFICATION OF TARGET OF EVALUATION The Target of Evaluation (TOE) is identified as follows: Table 1: TOE Identification TOE Name and Version CipherDrive v1.2.2 Developer KLC Group LLC 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. The TOE claims the following conformance: collaborative Protection Profile for Full Drive Encryption – Authorization Acquisition, v2.0 + Errata 20190201 1.2 TOE DESCRIPTION The TOE provides pre-boot user authentication for Opal 2.0 compliant Self encrypting drives (SEDs). It is designed to be used with a SED as a loosely coupled system to deliver secure Data-At-Rest (DAR) encryption. The TOE is installed on a read-only Shadow Master Boot Record (MBR) partition on the SED by booting from an external USB thumb drive or DVD containing the installer. After installation, the user authenticates to the TOE (via username/password and/or smartcard) which will unlock the SED drive and chain-boot to the host OS or Hypervisor environment. UNCLASSIFIED 8 TLP:WHITE 1.3 TOE ARCHITECTURE A diagram of the TOE architecture is as follows: TOE Architecture UNCLASSIFIED 9 TLP:WHITE 2 SECURITY POLICY The TOE implements and enforces policies pertaining to the following security functionality:  Cryptographic Support  Security Management  Protection of the TSF 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 has been evaluated by the CAVP and is used by the TOE: Table 2: Cryptographic Implementation Cryptographic Module/Algorithm Certificate Number KLC Group LLC CipherDrive v1.2 C1980, A972 UNCLASSIFIED 10 TLP:WHITE 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:  Users enable Full Drive Encryption on a newly provisioned or initialized storage device free of protected data in areas not targeted for encryption. The cPP does not intend to include requirements to find all the areas on storage devices that potentially contain protected data. In some cases, it may not be possible - for example, data contained in “bad” sectors. While inadvertent exposure to data contained in bad sectors or unpartitioned space is unlikely, one may use forensics tools to recover data from such areas of the storage device. Consequently, the cPP assumes bad sectors, un-partitioned space, and areas that must contain unencrypted code (e.g., MBR and AA/EE pre- authentication software) contain no protected data.  Upon the completion of proper provisioning, the drive is only assumed secure when in a powered off state up until it is powered on and receives initial authorization  Communication among and between product components (e.g., AA and EE) is sufficiently protected to prevent information disclosure. In cases in which a single product fulfils both cPPs, then the communication between the components does not extend beyond the boundary of the TOE (e.g., communication path is within the TOE boundary). In cases in which independent products satisfy the requirements of the AA and EE, the physically close proximity of the two products during their operation means that the threat agent has very little opportunity to interpose itself in the channel between the two without the user noticing and taking appropriate actions.  Authorized users follow all provided user guidance, including keeping password/passphrases and external tokens securely stored separately from the storage device and/or platform.  The platform in which the storage device resides (or an external storage device is connected) is free of malware that could interfere with the correct operation of the product.  External tokens that contain authorization factors are used for no other purpose than to store the external token authorization factors.  The user does not leave the platform and/or storage device unattended until all volatile memory is cleared after a power-off, so memory remnant attacks are infeasible. Authorized users do not leave the platform and/or storage device in a mode where sensitive information persists in non-volatile storage (e.g., lock screen). Users power the platform and/or storage device down or place it into a power managed state, such as a “hibernation mode”.  Authorized administrators ensure password/passphrase authorization factors have sufficient strength and entropy to reflect the sensitivity of the data being protected. UNCLASSIFIED 11 TLP:WHITE  The product does not interfere with or change the normal platform identification and authentication functionality such as the operating system login. It may provide authorization factors to the operating system's login interface, but it will not change or degrade the functionality of the actual interface.  All cryptography implemented in the Operational Environment and used by the product meets the requirements listed in the cPP. This includes generation of external token authorization factors by a RBG.  The platform 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 platform’s correct operation. 3.2 CLARIFICATION OF SCOPE  Only the functionality covered in the collaborative Protection Profile for Full Drive Encryption – Authorization Acquisition, v2.0 + Errata 20190201 is included within the scope of evaluation.  The TOE supports Opal 2.0 compliant SEDs but was only tested using the SEDs defined in section 4. The following configuration has not been evaluated:  Use of multiple drives UNCLASSIFIED 12 TLP:WHITE 4 EVALUATED CONFIGURATION The evaluated configuration for the TOE comprises: Software/Firmware CipherDrive v1.2.2 Build: 7 Hardware  Digistor DIG-M25126-SI  Digistor DIG-M2N22566-UI Environmental Support  Intel based UEFI booted systems that supports IntelSecure Key Technology. o Intel Atom x7-E3950 o Intel Core i5-9400H  When dual factor authentication is used, Federal Information Processing Standard (FIPS) 201 Personal Identity Verification Common Access Card (PIV-CAC) compliant smartcards and readers are required 4.1 DOCUMENTATION The following documents are provided to the consumer to assist in the configuration and installation of the TOE: a) KLC Group LLC, CipherDrive v1.2, KLC PBA, 11-17-2020 b) KLC CipherDrive v1.2 Common Criteria Guide, v1.1 UNCLASSIFIED 13 TLP:WHITE 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. UNCLASSIFIED 14 TLP:WHITE 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: a. PP Assurance Activities: The evaluator performed the assurance activities listed in the claimed PP b. Cryptographic Implementation Verification: The evaluator verified that the claimed cryptographic implementations were 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 15 TLP:WHITE 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 12/8/2020 and included the following search terms: CipherDrive Nginx v1.15.7 systemd-boot v241 OpenSSL v1.0.2u Uwsgi v2.8.16 Digistor (drive manufacturers) OpenSC v0.21 Qt v4.8.7 Drive encryption Disk encryption Key destruction Opal management software Self-encrypting drives Key sanitization SED management software Password caching Vulnerability searches were conducted using the following sources: Common Vulnerabilities and Exposures: http://cve.mitre.org/cve/ US-CERT : http://www.kb.cert.org/vuls/html/search National Vulnerability Database: https://nvd.nist.gov/ OpenSSL Vulnerabilities: https://www.openssl.org/news/vulnerabilities.html KLC website https://www.klc-group.com/ Google: https://www.google.com/ The independent penetration testing did not uncover any residual exploitable vulnerabilities in the intended operating environment.
