Catonsville, MD Axway Validation Authority Suite Validation Report Version 0.2, 07/19/2019 4 3 Architectural Information Note: The following architectural description is based on the description presented in the Security Target. The Axway Validation Authority (VA) Suite provides a comprehensive, scalable, and reliable framework for real-time validation of digital certifications for the Public Key Infrastructure (PKI). The Axway VA Suite provides a variety of PKI and certificate management functionality to prevent revoked credentials from being used for secure email, smart card login, network access (including wireless), or other sensitive electronic transactions. The Axway VA Suite provides the following functionality:  Maintains and processes a store of digital certificate revocation data by obtaining the digital Certificate Revocation List (CRL) from multiple CA or VA sources and performing end-to-end certificate validation if one or more intermediate CAs are used and the validation policy requires a complete certificate chain validation.  Generates and signs OCSP/SCVP responses.1 Maintains a cache loaded with OCSP responses that are pre-computed or dynamically built up by proxy client requests to a responder.  Allows caching of CRLs and delta CRLs to support non-OCSP clients or clients that want to maintain their own revocation data caches for backup and in low-bandwidth and non real-time environments.  Supports SSL-based communications with clients, digitally signed client requests/responses, and digitally signed XML logs and CRL archives, as well as SSL- based server administration.  Supports software PKCS #11 or CAPI token based hardware signing and encryption products, including hardware security modules from leading vendors that comply with FIPS 140-2 Level 2 or above.2 For purposes of this evaluation, the Axway VA Suite is a software application that offers CAVP certified cryptographic functions (key generation, hashing, signing, random bit generation), secure remote administration, secure storage of credentials, X.509 certificate validation and authentication, trusted update, anti-exploitation capabilities and restricted network communications. 3.1 TOE Evaluated Configuration Details regarding the evaluated configuration are provided in Section 8. 1 The generation and signing of OCSP/SCVP has not been tested in the evaluated configuration. 2 The use of a Hardware Security Module (HSM) is not included in the evaluated configuration. Axway Validation Authority Suite Validation Report Version 0.2, 07/19/2019 5 3.2 TOE Architecture The Axway Validation Authority Suite consists of three software components, the Validation Authority Server, the Desktop Validator (Standard and Enterprise Editions) and the Server Validator, which run on one of the following platforms:  Microsoft Windows 2012 (64 bit) on a 64 bit Intel Xeon processor  RHEL 7 (64 bit) on a 64 bit Intel Xeon processor The Windows and RHEL platforms are part of the operating environment of the TOE. The Axway VA Suite applications and the particular platforms they each run on are described below: 1. Validation Authority Server (VA Server) – the VA Server is comprised of the VA validation server acting as either a Repeater or Responder operating on a Windows or Linux platform, and the Web based administration (Admin UI). The VA Server maintains a store of digital certificate revocation data and ensures the integrity and validity of online transactions by delivering realtime validation of digital certificates. 2. Desktop Validator (DV) - (Standard and Enterprise Editions) - the Desktop Validator is a Microsoft CAPI compliant revocation trust provider that communicates with the Validation Authority Server (VA server) in responder mode to check status of digita l certs in real time. DV runs as a service on a 64bit Microsoft Windows platforms and can be invoked to validate standard X.509v3 digital certificates issued by any Certificate Authority (CA). The DV Standard edition provides certificate validation support for client applications, while the DV Enterprise edition provides certificate validation support for both client and server applications. 3. Server Validator (SV) – the Server Validator provides revocation status checking of client certificates for web servers. SV serves as an interface between a secure web server and a VA Server. The SV runs on Windows and Linux. Web servers requiring SSL and client authentication can use the Server Validator to add revocation checking for certificates to authenticate to web servers or web-enabled applications. The cryptographic capabilities of Axway VA Suite are provided by the Axway Security Kernel and are maintained across all three TOE software applications. The Axway Security Kernel (version 3.0.2) is a software cryptographic module that is implemented as two dynamic link libraries (DLLs) on Windows or two Shared Objects (SOs) on Linux. It is a user space shared library built upon a custom version of OpenSSL 1.0.2k. The implementation of TLS/HTTPS to secure communication channels is supported using Apache. The TOE components of the Axway VA Suite all share the same underlying cryptographic library and can be deployed together to provide a robust and flexible certificate validation solution that covers both desktop and web enabled applications. Axway Validation Authority Suite Validation Report Version 0.2, 07/19/2019 6 3.3 Physical Boundaries The TOE is composed of three software-only applications which execute on a Microsoft Windows or RHEL operating system platform. The underlying platform is considered part of the operating environment but provides some of the security functionality required by the ASPP12. Specifically, the evaluated configuration includes the following:  Axway Validation Authority Server v5.0 - a software server application running on the following two platforms: o Microsoft Windows 2012 (64 bit) on a 64 bit Intel Xeon processor o RHEL 7 (64 bit) on a 64 bit Intel Xeon processor  Axway Desktop Validator (Standard & Enterprise Editions)3 v5.0 – a software client application running on the following platform: o Microsoft Windows 2012 (64 bit) on a 64 bit Intel Xeon processor  Axway Server Validator v5.0 – a software client application running on the following two platforms: o Microsoft Windows 2012 (64 bit) on a 64 bit Intel Xeon processor o RHEL 7 (64 bit) on a 64 bit Intel Xeon processor Server Validator provides revocation checking for the following web servers in the operational environment: Apache 2.4.39 or higher and Oracle HTTP Server (OHS) 12c. 3 The Enterprise Edition of the Desktop Validator was tested in the evaluated configuration. Axway Validation Authority Suite Validation Report Version 0.2, 07/19/2019 7 4 Security Policy This section summaries the security functionality of the TOE: 1. Cryptographic support 2. User data protection 3. Identification and authentication 4. Security management 5. Privacy 6. Protection of the TSF 7. Trusted path/channels 4.1 Cryptographic support The TOE uses CAVP-validated cryptographic algorithm implementations, provided by the Axway Security Kernel, a cryptographic module built upon a custom version of OpenSSL 1.0.2k, to support asymmetric key generation, encryption/decryption, signature generation and verification and establishment of trusted channels to protect data in transit. The TOE provides a web server for TLS/HTTPS to facilitate trusted remote communications and implements functionality to securely store key data related to secure communications. The TOE also relies on the underlying platform to generate entropy that is used as input data for the TOE’s deterministic random bit generator (DRBG). 4.2 User data protection The TOE does not access any hardware resources or sensitive information repositories and no sensitive data is stored in non-volatile memory. Inbound and outbound network communications are restricted to those that are user-initiated. 4.3 Identification and authentication The TOE implements X509 certificate validation to validate the revocation status of certificates using CRL. The TOE uses X509 certificates to support HTTPS/TLS authentication. 4.4 Security management The TOE provides a Web-based Graphical User Interface (Web GUI) to access and manage the TOE security functions. When configured with default credentials or no credentials, the TOE restricts its functionality and only allows the ability to set new credentials. By default, the TOE is configured with file permissions to protect itself and its data from unauthorized access. Axway Validation Authority Suite Validation Report Version 0.2, 07/19/2019 8 4.5 Privacy The TOE does not transmit personally identifiable information (PII) over any network interfaces. 4.6 Protectionof the TSF The TOE protects itself against exploitation by implementing address space layout randomization (ASLR) and by not allocating any memory region for both write and execute permission. The TOE is compiled for both Windows and Linux with stack-based buffer overflow protection and does not allow user-modifiable files to be written to directories that contain executable files. The TOE uses standard platform APIs and includes a number of third party libraries used to perform its functions. The TOE includes mechanisms to check for updates and to query the current version of the application software. TOE software is digitally signed and distributed using the platform- supported package manager (Windows or Linux). The TOE does not update its own binary code in any way and when removed, all traces of the TOE application software are deleted. 4.7 Trusted path/channels The TOE protects communications between itself and remote administrators using HTTPS/TLS.

The scope of this evaluation was limited to the functionality and assurances covered in the ASPP12 as described for this TOE in the Security Target. 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. Clarification of scope 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 ASPP12 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.  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.  The functionality evaluated is scoped exclusively to the security functional requirements specified in the ASPP12 and applicable Technical Decisions. Any additional security related functional capabilities of the TOE were not covered by this evaluation.
