Product Description

The Target of Evaluation (TOE) is CyberFence 3e-636 Series Network Security Devices.  3eTI’s 636 Series Network Security Devices offer the multiple capabilities necessary for protecting embedded devices and safety-critical industrial control systems (ICS) against internal and external attacks.  The core capabilities include: network access control, OSI Layer 2 and Layer 3 packet filtering, industrial control protocols packet inspection and secured application data transportation (via encryption).


Evaluated Configuration

The CyberFence 3e-636 Series Network Security Devices TOE is a combination of hardware and software.  All devices run software version 5.2.0. The evaluated hardware models are:

·         3e-636L3 EtherGuard

·         3e-636L2 Darknode

·         3e-636H Ultracrypt

·         3e-636A EtherWatch

 


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 Ultra Electronics 3eTI 636-Series User’s Guide, April 2020, 29000533-002, Revision F document, satisfies all of the security functional requirements stated in the CyberFence 3e-636 Series Network Security Devices (NDcPP21) Security Target, Version 0.8, 07/06/2020.  The project underwent CCEVS Validator review.  The evaluation was completed in July 2020.  Results of the evaluation can be found in the Common Criteria Evaluation and Validation Scheme Validation Report (report number CCEVS-VR-VID11080-2020) prepared by CCEVS.

 


Environmental Strengths

The logical boundaries of the CyberFence 3e-636 Series Network Security Devices are realized in the security functions that it implements. Each of these security functions is summarized below.

 

Security Audit:

The TOE generates auditable events for actions on the TOE with the capability of selective audit record generation. The records of these events can be viewed within the TOE Management Interface or they can be exported to audit systems in the Operational Environment. The TOE generates records for its own actions, containing information about the user/process associated with the event, the success or failure of the event, and the time that the event occurred. Additionally, all administrator actions relating to the management of TSF data and configuration data are logged by the TOE’s audit generation functionality.

 

Cryptographic support:

The TOE uses NIST SP 800-90 DRBG random bits generator and the following cryptographic algorithms: AES, RSA, ECDSA, SHA, HMAC to secure the trusted channel and trusted path communication. The TOE is designed to zeroize Critical Security Parameters (CSPs) to mitigate the possibility of disclosure or modification.

Identification and authentication:

The TOE provides Identification and Authentication security functionality to ensure that all users are properly identified and authenticated before accessing TOE functionality. The TOE enforces a password-based authentication mechanism to perform administrative user authentication. Passwords are obscured when being displayed during any attempted login.  Administrative users can be authenticated via the TOE’s local user database. The TOE also authenticates its IPsec peers; the authentication is performed over IKEv2 SA phase of mutual authentication between IPsec peers.

Security management:

The Web Management Application of the TOE provides the capabilities for configuration and administration. The Web Management Application can be accessed via the dedicated local Ethernet port configured for “out-of-band” management. There is no local access such as a serial console port. Therefore, the local and remote management is considered the same for this evaluation. 

An authorized administrator can modify, edit, and delete security parameters such as audit data, configuration data, and user authentication data.   The Web Management Application also offers an authorized administrator the capability to manage how security functions behave. For example, an administrator can enable/disable certain audit functions query and set encryption/decryption algorithms used for network packets.

Protection of the TSF:

Internal testing of the TOE hardware, software, and software updates against tampering ensures that all security functions are running and available before the TOE accepts any communications.  The TSF prevents reading of pre-shared keys, symmetric keys, private keys, and passwords.  The TOE uses electronic signature verification before any firmware/software updates are installed.

TOE Access:

The TOE provides the following TOE Access functionality:

  • TSF-initiated session termination when a connection (remote or local) is idle for a configurable time period
  • Administrative termination of own session
  • TOE Access Banners

Trusted path/channels:

The TOE protects interactive communication with administrators using TLS/HTTPS, both integrity and disclosure protection is ensured.  The TOE uses IPsec to protect communication with network entities, such as a log server and NTP server. This prevents unintended disclosure or modification of logs and management information.
