Architectural Information Note: The following architectural description is based on the description presented in the Security Target. 3.1 TOE Introduction The TOE is a hardware and software TOE consisting of the RUGGEDCOM ROS v4.2.2.F running on the M2100F, M2200F, M969F, RSG2100F, RSG2100PF, RSG2200F, RSG2300F, RSG2300PF, RSG2488F, RS400F, RS416F, RS416PF, RS900F, RS900GF, RS900GPF, and RS940GF RUGGEDCOM switches. The purpose of the TOE is to provide Ethernet switching capabilities in a ruggedized enclosure for customer networks in virtually any environment. RUGGEDCOM ROS may be deployed on any of the RUGGEDCOM switches mentioned in the TOE above and listed in the “Physical Boundaries†section below. The RUGGEDCOM switches are highly configurable and can be customized with a number of different line module and power supply combinations. Customers choose a configuration that suits the targeted network and Siemens assembles the RUGGEDCOM switches according to the specific configuration. The RUGGEDCOM switches are able to operate in the most adverse conditions and are primarily deployed in power distribution, refineries, or traffic control systems. These RUGGEDCOM switches are designed specifically to withstand harsh environmental conditions including temperature and humidity extremes, shock, vibration, and electromagnetic interference. VALIDATION REPORT Siemens RUGGEDCOM Rugged Operating System (ROS) v4.2.2.F 4 3.2 Physical Boundaries The physical scope and the physical boundary of the TOE is composed of both the RUGGEDCOM switch hardware and the RUGGEDCOM ROS v4.2.2.F software. For the evaluated configuration, TOE software (ROS v4.2.2.F) was installed and run in the TOE hardware configurations shown in the Table 2 below. The line models on each switch model are configurable and the tested configurations provide a sample of possible configurations. The line modules provide 10/100/1000BaseTX Ethernet, serial, and fiber interfaces that are used to send and receive user data. The line modules provide nothing more than the physical interface.

Security Policy This section summarizes the security functionality of the TOE. 4.1 Security Audit The TOE generates audit records for security-relevant actions of the authorized administrators accessing the TOE via the terminal-based menu and web interface. The TOE records the identity of the administrator responsible for the log event, where applicable. To remotely and securely backup the audit logs, an Administrator can configure the syslog server to call into the TOE and request audit log files be printed to the syslog server over an SSH connection. The connection to the audit server is secured using SSH. When logs are filled, the TOE overwrites in two possible ways: the oldest log record can be overwritten with the new log record or the oldest log file can be overwritten with the new log file. 4.2 Cryptographic Support The TOE algorithms were validated through the Cryptographic Algorithm Validation Program (CAVP). The TOE contains cryptographic support that provides key generation, random bit generation, encryption/decryption, digital signature and secure hashing, key-hashing, and key establishment features in support of higher level cryptographic protocols including SSH and TLS. 4.3 Identification and Authentication The TOE provides functionality that requires administrators to verify their claimed identity. The TOE ensures that only authorized administrators can gain access to configuration and management settings. Administrators can only view the access banner prior to authenticating with a valid user name and password. The TOE requires administrators to use strong passwords. The TOE provides no feedback to Administrators when they are entering their passwords at the login prompt of the terminal-based menu for both direct serial and remote SSH connections. Administrators using password-based authentication are locked out after a configurable number of unsuccessful authentication attempts and must wait a configurable period of time before they are unlocked. The TOE can present a certificate to authenticate to external entities and this certificate and the VALIDATION REPORT Siemens RUGGEDCOM Rugged Operating System (ROS) v4.2.2.F 7 trust anchor certificate are stored within a truststore. Certificate revocation status is verified on certificates uploaded to the TOE using an external Online Certificate Status Protocol (OCSP) server. 4.4 Security Management The TOE provides a web interface and a terminal-based menu for administrators to manage the security functions, configuration, and other features of the TOE. The security management function specifies user roles with defined access for the management of the TOE components. Updating the TOE, modifying the configuration file, configuring the access banner, setting the inactivity timeout, configuring authentication failure parameters, configuring time and re-enabling the Administrator account are all functions restricted to the Security Administrator. 4.5 Protection of the TSF The TOE invokes a set of self-tests each time the TOE is powered on to ensure that the TSF operates correctly. The TOE also provides a reliable timestamp for its own use. An Administrator can manually set the time for the TOE. A digital signature using an RSA public key is used to verify all software updates that are applied to the TOE. The TOE prevents an administrator from reading the keys stored in the TOE. Passwords are stored in obfuscated form to prevent them from being read in plaintext. 4.6 TOE Access The TOE terminates local and remote management sessions after an administrator- configurable time period of inactivity. The TOE also provides administrator’s the capability to manually terminate the session prior to the inactivity timeout. After an administrator’s session is terminated, the administrator must log in again to regain access to TOE functionality. A login banner is displayed at the login screen of the web interface and prior to authentication over the terminal-based menu. 4.7 Trusted Path / Channels The cryptographic functionality of the TOE provides the TOE the ability to create trusted paths and trusted channels. The TOE implements a trusted channel using SSH between itself and a remote server in order to protect the audit logs as they are being sent. Additionally, the TOE provides trusted paths between administrators and the web interface via HTTPS and the terminal-based menu via SSH. The management communication channels between the TOE and a remote entity are distinct from network data communication channels and provide mutual identification and authentication. In addition, the communications are protected from modification and disclosure. VALIDATION REPORT Siemens RUGGEDCOM Rugged Operating System (ROS) v4.2.2.F 8 5. Assumptions The Security Problem Definition, including the assumptions, may be found in the following document:  collaborative Protection Profile for Network Devices, Version 2.0 + Errata 20180314 That information has not been reproduced here and the CPP_ND_V2.0E should be consulted if there is interest in that material. 6. 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 CPP_NDV2.0E 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 strictly to the security functional requirements specified in the CPP_ND_V2.0E and applicable Technical Decisions. Any additional security or non-security related functional capabilities of the product (defined in Section 1.5.3 of the Security Target) were not covered by this evaluation. o Specifically, the following product features were not in the scope of evaluation and thus were not tested:  Virtual Local Area Network configuration  Port configuration  Broadcast Storm filtering  Quality of Service based on part, tag, MAC16, or IP type of service  Multiple Spanning Tree Protocol  Rapid Spanning Tree Protocol  Enhanced Rapid Spanning Tree Protocol o The following services are present in the TOE but are excluded from use in the evaluated configuration:  RADIUS  TACACS+  RSH VALIDATION REPORT Siemens RUGGEDCOM Rugged Operating System (ROS) v4.2.2.F 9  Telnet  TFTP  ModBus Management  Remote Syslog  Management connections over SNMP v1, v2, and v3  Management via HTTP  Network Time Protocol (NTP) time synchronisation and service  RUGGEDCOM Discovery Protocol (RCDP)  IP Forwarding. 7.
