It presents a summary of the PPAPP11 and the evaluation results. In order to promote thoroughness and efficiency, the evaluation of the PPAPP11 was performed concurrent with the first product evaluation against the PP’s requirements. In this case the Target of Evaluation (TOE) for this first product was the CyberReliant Corporation’s (CRC) Data at Rest (DaR) Service (Native) Version 1.0.0 (Version Code 2). The evaluation was performed by Gossamer Security Solutions Common Criteria Testing Laboratory (CCTL) in Catonsville, Maryland, in the United States and was completed in October 2015. This evaluation addressed the base requirements of the PPAPP11, as well as a few of the optional, selection-based and objective requirements contained in the Appendices. The information in this report is largely derived from the Assurance Activity Report (AAR), written by the Gossamer Security Solutions. The evaluation determined that the PPAPP11 is both Common Criteria Part 2 Extended and Part 3 Extended. The PP identified in this Validation Report has been evaluated at a NIAP approved Common Criteria Testing Laboratory using the Common Methodology for IT Security Evaluation (Version 3.1, Rev 4) for conformance to the Common Criteria for IT Security Evaluation (Version 3.1, Rev 4). Because the ST contains only material drawn directly from the PPAPP11, performance of the majority of the ASE work units serves to satisfy the APE work units as well. Where this is not the case, the lab performed the outlying APE work units as part of this evaluation. 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 found that the evaluation showed that the PPAPP11 meets the requirements of the APE components. These findings were confirmed by the VR author. The conclusions of the testing laboratory in the assurance activity report are consistent with the evidence produced. 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). CCTLs evaluate products against Protection Profile containing Assurance Activities, which are interpretations of CEM work units specific to the technology described by the PP. In order to promote thoroughness and efficiency, the evaluation of the PPAPP11 was performed concurrent with the first product evaluation against the PP. In this case the TOE for this first product was the Data at Rest (DaR) Service (Native) Version 1.0.0 (Version Code 2), provided by CyberReliant Corporation’s (CRC). Gossamer Security Solutions Common 1 Protection Profile for Application Software, Version 1.1, November 5, 2014 Criteria Testing Laboratory (CCTL) in Catonsville, Maryland, in the United States and was completed in October 2015. The PPAPP11 contains a set of “base” requirements that all conformant STs must include as well as “additional” requirements that are either optional, selection-based, or objective depending on the requirement in question. The vendor may choose to include such requirements in the ST and still claim conformance to this PP. If the vendor’s TOE performs capabilities that are governed by any additional requirements, that vendor is expected to claim all of the additional requirements that relate to these capabilities. Because these additional requirements may not be included in a particular ST, the initial use of the PP will address (in terms of the PP evaluation) the base requirements as well as any additional requirements that are incorporated into that initial ST. Subsequently, TOEs that are evaluated against the PPAPP11 that incorporate additional requirements that have not been included in any ST prior to that will be used to evaluate those requirements (APE_REQ), and any appropriate updates to this validation report will be made. The following identifies the PP subject to the evaluation/validation, as well as the supporting information from the base evaluation performed against this PP, as well as subsequent evaluations that address additional requirements in the PPAPP11.

Some application types are covered by more specific PPs, which may be expressed as Extended Packages of this PP. Such applications are subject to the requirements of both this PP and the Extended Package that addresses their special functionality. PPs for some particularly specialized applications may not be expressed as EPs at this time, though the requirements in this document should be seen as objectives for those highly specialized applications. 4 Security Problem Description and Objectives 4.1 Assumptions The specific conditions listed in the following subsections are assumed to exist in the TOE’s environment. These assumptions include both practical realities in the development of the TOE security requirements and the essential environmental conditions on the use of the TOE. Assumption Name Assumption Definition A.PLATFORM The TOE relies upon a trustworthy computing platform for its execution. This includes the underlying platform and whatever runtime environment it provides to the TOE. A.PROPER_USER The user of the application software is not willfully negligent or hostile, and uses the software in compliance with the applied enterprise security policy. A.PROPER_ADMIN The administrator of the application software is not careless, willfully negligent or hostile, and administers the software within compliance of the applied enterprise security policy. Table 1: Assumptions 4.2 Threats Threat Name Threat Definition T.NETWORK_ATTACK An attacker is positioned on a communications channel or elsewhere on the network infrastructure. Attackers may engage in communications with the application software or alter communications between the application software and other endpoints in order to compromise it. T.NETWORK_EAVESDROP An attacker is positioned on a communications channel or elsewhere on the network infrastructure. Attackers may monitor and gain access to data exchanged between the application and other endpoints. T.LOCAL_ATTACK An attacker can act through unprivileged software on the same computing platform on which the application executes. Attackers may provide maliciously formatted input to the application in the form of files or other local communications. T.PHYSICAL_ACCESS An attacker may try to access sensitive data at rest. 3 Protection Profile for Application Software, Version 1.1, November 5, 2014 Table 2: Threats 4.3 Organizational Security Policies The APP PP does not define organizational security policies. 4.4 Security Objectives The following table contains security objectives for the TOE. TOE Security Obj. TOE Security Objective Definition O.INTEGRITY Conformant TOEs ensure the integrity of their installation and update packages, and also leverage execution environment-based mitigations. Software is seldom if ever shipped without errors, and the ability to deploy patches and updates to fielded software with integrity is critical to enterprise network security. Processor manufacturers, compiler developers, execution environment vendors, and operating system vendors have developed execution environment-based mitigations that increase the cost to attackers by adding complexity to the task of compromising systems. Application software can often take advantage of these mechanisms by using APIs provided by the runtime environment or by enabling the mechanism through compiler or linker options. O.QUALITY To ensure quality of implementation, conformant TOEs leverage services and APIs provided by the runtime environment rather than implementing their own versions of these services and APIs. This is especially important for cryptographic services and other complex operations such as file and media parsing. Leveraging this platform behavior relies upon using only documented and supported APIs. O.MANAGEMENT To facilitate management by users and the enterprise, conformant TOEs provide consistent and supported interfaces for their security-relevant configuration and maintenance. This includes the deployment of applications and application updates through the use of platform-supported deployment mechanisms and formats, as well as providing mechanisms for configuration. O.PROTECTED_STORAGE To address the issue of loss of confidentiality of user data in the event of loss of physical control of the storage medium, conformant TOEs will use data-at-rest protection. This involves encrypting data and keys stored by the TOE in order to prevent unauthorized access to this data. O.PROTECTED_COMMS To address both passive (eavesdropping) and active (packet modification) network attack threats, conformant TOEs will use a trusted channel for sensitive data. Sensitive data includes cryptographic keys, passwords, and any other data specific to the application that should not be exposed outside of the application. Table 3: Security Objectives for the TOE The following table contains objectives for the Operational Environment. TOE Security Obj. TOE Security Objective Definition OE.PLATFORM The TOE relies upon a trustworthy computing platform for its execution. This includes the underlying operating system and any discrete execution environment provided to the TOE. 4 Protection Profile for Application Software, Version 1.1, November 5, 2014 TOE Security Obj. TOE Security Objective Definition OE.PROPER_USER The user of the application software is not willfully negligent or hostile, and uses the software within compliance of the applied enterprise security policy. OE.PROPER_ADMIN The administrator of the application software is not careless, willfully negligent or hostile, and administers the software within compliance of the applied enterprise security policy. Table 4: Security Objectives for the Operational Environment 5 Requirements As indicated above, requirements in the PPAPP11 are comprised of the “base” requirements and additional requirements that are either optional, selection-based, or objective depending on the requirement in question. The following are table contains the “base” requirements that were validated as part of the CyberReliant evaluation activity referenced above. The following table contains the additional optional requirements contained in Appendix A, and an indication of what evaluation those requirements were verified in (from the list in the Identification section above).
