The Target of Evaluation (TOE) is the Apriva MESA VPN 3.0. The Apriva MESA VPN server is an IPsec VPN gateway designed to provide mobile devices with a secure connection to a protected network. The Apriva MESA VPN is a standards-based VPN concentrator with no proprietary modes of operation, and supporting most native VPN clients in Microsoft, Android, and Apple iOS operating systems.
Security Evaluation Summary
The evaluation was carried out in accordance to the Common Criteria Evaluation and Validation Scheme (CCEVS) requirements and guidance. The evaluation demonstrated that the TOE meets the security requirements contained in the Security Target. The criteria against which the TOE was judged are described in the Common Criteria for Information Technology Security Evaluation, Version 3.1, Revision 5, April 2017. The evaluation methodology used by the evaluation team to conduct the evaluation is the Common Methodology for Information Technology Security Evaluation, Evaluation Methodology, Version 3.1, Revision 5, April 2017. The product, when delivered and configured as identified in the Apriva® MESA VPN Common Criteria Guidance, Version 3.11, July 18, 2023 document, satisfies all of the security functional requirements stated in the Apriva MESA VPN v3.0 Security Target, Version 0.4, July 18, 2023. The project underwent CCEVS Validator review. The evaluation was completed in July 2023. Results of the evaluation can be found in the Common Criteria Evaluation and Validation Scheme Validation Report (report number CCEVS-VR-VID11363-2023) prepared by CCEVS.
The logical boundaries of the Apriva MESA VPN 3.0 are realized in the security functions that it implements. Each of these security functions is summarized below.
The TOE is able to generate logs for a wide range of security relevant events. The TOE always stores the logs locally so they can be accessed by an administrator and can be configured to send the logs to a designated log server using TLS to protect the logs while in transit on the network.
The TOE contains a CAVP-tested cryptographic module that provides key management, random bit generation, encryption/decryption, digital signature and secure hashing and key-hashing features in support of higher-level cryptographic protocols including IPsec, TLS, and SSH.
Identification and authentication:
The TOE requires users to be identified and authenticated before they can use functions mediated by the TOE, with the exception of specific ICMP response. It provides the ability to perform password and public key authentication for administrative users.
The TOE implements a limited command line interface (CLI) to allow authorized administrators to configure the TOE. This interface restricts the administrator to executing commands required to configure and administer the TOE. All administrative activity and functions including security management commands are limited to authorized users (i.e., administrators) only after they have provided acceptable user identification and authentication data to the TOE.
The TOE provides extensive packet filtering capabilities for IPv4, IPv6, TCP, and UDP. The authorized administrator can define packet filtering rules that apply to most every field within the identified packet types. The authorized administrator can define each rule to permit, deny, and log each decision.
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 particularly sensitive data such as stored passwords and cryptographic keys so that they are not accessible even by an administrator. It also provides its own timing mechanism to ensure that reliable time information is available (e.g., for log accountability).
The TOE includes functions to perform self-tests so that it might detect when it is failing. It also includes mechanisms (i.e., verification of the digital signature of each new image) so that the TOE itself can be updated while ensuring that the updates will not introduce malicious or other unexpected changes in the TOE.
The TOE can be configured to display a login banner when an administrator establishes an interactive session and subsequently will enforce an administrator-defined inactivity timeout value after which the inactive session (local or remote) will be terminated. The TOE can also restrict VPN clients based on location and time and can assign a private VPN address to a client.
The TOE protects interactive communication with administrators using SSH for CLI access to ensure both integrity and disclosure protection. If the negotiation of an encrypted session fails or if the user does not have authorization for remote administration, an attempted connection will not be established.
The TOE protects communication with the audit log server using TLS connections to prevent unintended disclosure or modification of logs. The TOE can establish IPsec connections with clients and peers.
