It presents the evaluation results, their justifications, and the conformance results. This Validation Report (VR) is not an endorsement of the Target of Evaluation (TOE) by any agency of the U.S. government, and no warranty is either expressed or implied. The evaluation was performed by the Gossamer Security Solutions (Gossamer) Common Criteria Testing Laboratory (CCTL) in Columbia, MD, United States of America, and was completed in July 2022. The information in this report is largely derived from the Evaluation Technical Report (ETR) and associated test reports, all written by Gossamer Security Solutions. The evaluation determined that the product is both Common Criteria Part 2 Extended and Part 3 Conformant, and meets the assurance requirements of the collaborative Protection Profile for Full Drive Encryption - Authorization Acquisition, Version 2.0 + Errata 20190201, 01 February 2019 and the collaborative Protection Profile for Full Drive Encryption - Encryption Engine, Version 2.0 + Errata 20190201, 01 February 2019. The TOE is the Galleon Embedded Computing XSR and G1 Software Encryption Layer. The TOE identified in this VR has been evaluated at a NIAP approved CCTL using the Common Methodology for IT Security Evaluation (Version 3.1, Rev 5) for conformance to the Common Criteria for IT Security Evaluation (Version 3.1, Rev 5). This VR applies only to the specific version of the TOE as evaluated. The evaluation has been conducted in accordance with the provisions of the NIAP Common Criteria Evaluation and Validation Scheme (CCEVS) and the conclusions of the testing laboratory in the evaluation technical report are consistent with the evidence provided. The validation team monitored the activities of the evaluation team, provided guidance on technical issues and evaluation processes, and reviewed the individual work units and successive versions of the ETR. The validation team found that the evaluation showed that the product satisfies all of the functional requirements and assurance requirements stated in the Security Target (ST). Therefore, the validation team concludes that the testing laboratory’s findings are accurate, the conclusions justified, and the conformance results are correct. The conclusions of the testing laboratory in the ETR are consistent with the evidence produced. The technical information included in this report was obtained from the Galleon Embedded Computing XSR and G1 Software Encryption Layer Security Target, version 1.5, July 14, 2022 and analysis performed by the validation team. Galleon Embedded Computing XSR Validation Report Version 1.0, July 28, 2022 and G1 Software Encryption Layer 2 2 Identification The CCEVS is a joint National Security Agency (NSA) and National Institute of Standards and Technology (NIST) effort to establish commercial facilities to perform trusted product evaluations. Under this program, security evaluations are conducted by commercial testing laboratories called Common Criteria Testing Laboratories (CCTLs) using the Common Evaluation Methodology (CEM) in accordance with National Voluntary Laboratory Assessment Program (NVLAP) accreditation. The NIAP Validation Body assigns Validators to monitor the CCTLs to ensure quality and consistency across evaluations. Developers of information technology products desiring a security evaluation contract with a CCTL and pay a fee for their product’s evaluation. Upon successful completion of the evaluation, the product is added to NIAP’s Validated Products List. Table 1 provides information needed to completely identify the product, including: • The TOE: the fully qualified identifier of the product as evaluated. • The ST, describing the security features, claims, and assurances of the product. • The conformance result of the evaluation. • The Protection Profile to which the product is conformant. • The organizations and individuals participating in the evaluation.

Clarification of scope The scope of this evaluation was limited to the functionality and assurances covered in the CPP_FDE_AA_V2.0E/CPP_FDE_EE_V2.0E and applicable Technical Decisions 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 Full Drive Encryption Protection Profiles 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 Guide, additional customer documentation for the specific Full Drive Encryption models was not included in the scope of the evaluation and therefore should not to 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. Galleon Embedded Computing XSR Validation Report Version 1.0, July 28, 2022 and G1 Software Encryption Layer 5 4 Architectural Information Note: The following architectural description is based on the description presented in the ST. The TOE is the Galleon Embedded Computing XSR and G1 Software Encryption Layer. The TOE provides software Full Drive Encryption of removable drives and can be installed on Galleon’s XSR or G1 models. All models use Intel 64-bit CPUs, and Galleon offers the G1 with a single CPU model while offering the XSR with a range of CPUs to allow customers to tailor the system to their needs. The XSR and G1 (hereafter referred to as the Products) can act in multiple different capacities (Network Attached Storage [NAS], data recorder, general server, etc.) and allow for encryption of the Removable Data Module (RDM) attached to the system. The XSR model supports encryption of one RDM (at a time), up to 4 internal SSDs, and its internal, non-removable mSATA SSD. The G1 model also supports encryption of one RDM (at a time) and up to 2 internal SSDs. Both securely encrypt all user data stored within either model. The Products run the Red Hat Enterprise Linux (RHEL) Release 8.4 operating system. The Products provide a software-based Full Disk Encryption (FDE) of the removable drive within each RDM. In addition to the software-based FDE layer, the TOE also provides a hardware-based Full Drive Encryption (FDE) layer to encrypt the drive within each RDM. The hardware-based FDE layer is addressed in a separate evaluation. The TOE, whether operating as a NAS or a more general server, supports encrypting the data of additional software running on the TOE’s operating system. The TOE might include software to support protocols including CIFS and NFS or might include the vendor’s data recording software or even include customer provided software applications. The RHEL administrator can enable, disable, or install additional (accessing the system directly) desired protocols and software applications to support their use-case and application. 4.1 TOE Evaluated Platforms The following table summarizes the CPU options available (bold denotes the models used during evaluation testing, while italics denotes equivalent models). Model Processor XSR Intel Xeon E3-1505Lv6 (Kaby Lake) XSR Intel Xeon E3-1505Mv6 (Kaby Lake) XSR Intel Xeon E-2276ME (Coffee Lake) XSR Intel Xeon E-2276ML (Coffee Lake) G1 Intel Atom C2758 (Rangeley) 4.2 TOE Architecture The TOE provides a software Full Drive Encryption solution that can encrypt a Removable Data Module (RDM) which contain a data drive within as well as additional internal SSDs. Galleon Embedded Computing XSR Validation Report Version 1.0, July 28, 2022 and G1 Software Encryption Layer 6 4.3 Physical Boundaries The TOE’s physical boundary is the physical perimeter of its enclosure. The TOE provides a ruggedized solution to secure Data at Rest (DAR). Galleon Embedded Computing XSR Validation Report Version 1.0, July 28, 2022 and G1 Software Encryption Layer 7 5 Security Policy This section summaries the security functionality of the TOE: 1. Cryptographic support 2. User data protection 3. Security management 4. Protection of the TSF 5.1 Cryptographic support The TOE includes cryptographic functionality for key management, user authentication, and block-based encryption including: symmetric key generation, encryption/decryption, cryptographic hashing, keyed-hash message authentication, and password-based key derivation. These functions are supported with suitable random bit generation, key derivation, salt generation, initialization vector generation, secure key storage, and key destruction. These primitive cryptographic functions are used to encrypt Data-At-Rest (including the generation and protection of keys and key encryption keys) used by the TOE. 5.2 User data protection The TOE performs Full Drive Encryption on all partitions on the drive (so that no plaintext exists) and does so without user intervention. 5.3 Security management The TOE provides each of the required management services to manage the full drive encryption using a command line interface. 5.4 Protection of the TSF The TOE implements a number of features to protect itself to ensure the reliability and integrity of its security features. It protects key and key material and includes functions to perform self-tests and software/firmware integrity checking so that it might detect when it is failing or may be corrupt. If any of the self-tests fail, the TOE will not go into an operational mode.
