Security Recommendations and Considerations

The following describes important security-related recommendations and suggestions that should be considered before implementing the RSG2200 on any network:
• Section 1.2.1, “Security Recommendations”
• Section 1.2.2, “Key Files”
Section 1.2.1

Security Recommendations

To prevent unauthorized access to the device, note the following security recommendations:
• Do not connect the device to the Internet. Deploy the device only within a secure network perimeter.
• Replace the default passwords for all user accounts and processes (where applicable) before the device is deployed.
• Use strong passwords. Avoid weak passwords such as password1, 123456789, abcdefgh, etc. For more information about creating strong passwords, refer to the password requirements in Section 4.3, “Configuring
Passwords”.
• Make sure passwords are protected and not shared with unauthorized personnel.
• Passwords should not be re-used across different usernames and systems, or after they expire.
• When RADIUS authentication is done remotely, make sure all communications are within the security perimeter or on a secure channel.
• SSL and SSH keys are accessible to users who connect to the device via the serial console. Make sure to take appropriate precautions when shipping the device beyond the boundaries of the trusted environment:
▪ Replace the SSH and SSL keys with throwaway keys prior to shipping.
▪ Take the existing SSH and SSL keys out of service. When the device returns, create and program new keys
for the device.
• Restrict physical access to the device to only trusted personnel. A person with malicious intent could extract critical information, such as certificates, keys, etc. (user passwords are protected by hash codes), or reprogram the device.
• Control access to the serial console to the same degree as any physical access to the device. Access to the serial console allows for potential access to the ROS boot loader, which includes tools that may be used to gain complete access to the device.
• Only enable services that will be used on the device, including physical ports. Unused physical ports could potentially be used to gain access to the network behind the device.
• If SNMP is enabled, limit the number of IP addresses that can connect to the device and change the community names. Also configure SNMP to raise a trap upon authentication failures. For more information, refer to Section 5.7, “Managing SNMP”.
• Avoid using insecure services such as Telnet and TFTP, or disable them completely if possible. These services are available for historical reasons and are disabled by default.
2 Security Recommendations and Considerations
RUGGEDCOM ROS
User Guide
• Limit the number of simultaneous Web Server, Telnet and SSH sessions allowed.
• Configure remote system logging to forward all logs to a central location. For more information, refer to
Section 3.5, “Managing Logs”.
• Configuration files are provided in the CSV (comma separated values) format for ease of use. Make sure configuration files are properly protected when they exist outside of the device. For instance, encrypt the files, store them in a secure place, and do not transfer them via insecure communication channels.
• Management of the configuration file, certificates and keys is the responsibility of the device owner. Before returning the device to Siemens for repair, make sure encryption is disabled (to create a cleartext version of the configuration file) and replace the current certificates and keys with temporary throwaway certificates and keys that can be destroyed upon the device's return.
• Be aware of any non-secure protocols enabled on the device. While some protocols, such as HTTPS and SSH, are secure, others, such as Telnet and RSH, were not designed for this purpose. Appropriate safeguards against non-secure protocols should be taken to prevent unauthorized access to the device/network.
• Configure port security features on access ports to prevent a third-party from launching various attacks that can harm the network or device. For more information, refer to Section 5.10, “Managing Port Security”.
• Periodically audit the device to make sure it complies with these recommendations and/or any internal security policies.

Introduction
Section 1.2.2

Key Files

ROS uses security keys to establish secure remote logins (SSH) and Web access (SSL).
It is strongly recommended that a unique SSL certificate and SSH keys be created and provisioned. New ROS ­based units from Siemens will be shipped with a unique certificate and keys preconfigured in the ssl.crt and ssh.keys flash files.
The default and auto-generated SSL certificates are self-signed. It is recommended to use an SSL certificate that is either signed by a trusted third-party Certificate Authority (CA) or by an organization's own CA. This technique is described in the Siemens application note: Creating/Uploading SSH Keys and SSL Certificates to ROS Using Windows, available from www.siemens.com/ruggedcom.
The sequence of events related to Key Management during an upgrade to ROS v4.1 or later is as follows:
NOTE
The auto-generation of SSH keys is not available for Non-Controlled (NC) versions of ROS.
• On first boot, ROS will start the SSH and SSL services using the default keys.
• Immediately after boot, ROS will start to generate a unique SSL certificate and SSH key pair, and save each one to its corresponding flash file. This process may take several minutes to complete. As each one is created, the corresponding service is immediately restarted with the new keys.
• At any time during the key generation process, custom keys can be uploaded. The custom keys will take precedence over both the default and auto-generated keys.
• On subsequent boot, if there is a valid ssl.crt file, the default certificate will not be used for SSL. If there is a valid ssh.keys file, the default SSH key will not be used.
• At any time, new keys may be uploaded or generated by ROS using the sslkeygen or sshkeygen CLI commands.
The following sections describe SSL certificates and SSH key pairs in more detail:

• Section 1.2.2.2, “SSH Key Pairs”
Section 1.2.2.1
SSL Certificates
ROS supports SSL certificates that conform to the following specifications:
• X.509 v3 digital certificate format
• PEM format
• RSA key pair, 512 to 2048 bits
The RSA key pair used in the default certificate and in those generated by ROS uses a public key of 1024 bits in length.
NOTE
RSA keys smaller than 1024 bits in length are not recommended. Support is only included here for compatibility with legacy equipment.
User Guide
NOTE
The default certificate and keys are common to all ROS versions without a certificate or key files. That is why it is important to either allow the key auto-generation to complete or to provision custom keys. In this way, one has at least unique, and at best, traceable and verifiable keys installed when establishing secure communication with the unit.
NOTE
RSA key generation times increase depending on the key length. 1024 bit RSA keys may take several minutes to generate, whereas 2048 bit keys may take significantly longer. A typical modern PC system, however, can generate these keys in seconds.
The following (bash) shell script fragment uses the openssl command line utility to generate a self-signed X.509 v3 SSL certificate with a 1024 bit RSA key suitable for use in ROS . Note that two standard PEM files are required: the SSL certificate and the RSA private key file. These are concatenated into the resulting ssl.crt file, which may then be uploaded to ROS:
# RSA key size: BITS=1024 # 20 years validity: DAYS=7305
# Values that will be stored in the Distinguished Name fields:
COUNTRY_NAME=CA # Two-letter country code STATE_OR_PROVINCE_NAME=Ontario # State or Province LOCALITY_NAME=Concord # City ORGANIZATION=Ruggedcom.com # Your organization's name ORGANIZATION_CA=${ORGANIZATION}_CA # Your Certificate Authority COMMON_NAME=RC # The DNS or IP address of the ROS unit ORGANIZATIONAL_UNIT=ROS # Organizational unit name
# Variables used in the construction of the certificate REQ_SUBJ="/C=${COUNTRY_NAME}/ST=${STATE_OR_PROVINCE_NAME}/L=${LOCALITY_NAME}/O=${ORGANIZATION}/OU= ${ORGANIZATIONAL_UNIT}/CN=${COMMON_NAME}/" REQ_SUBJ_CA="/C=${COUNTRY_NAME}/ST=${STATE_OR_PROVINCE_NAME}/L=${LOCALITY_NAME}/O=${ORGANIZATION_CA}/ OU=${ORGANIZATIONAL_UNIT}/"

ModBus Management Support

Modbus management support in RUGGEDCOM devices provides a simple interface for retrieving basic status information. ModBus support simplifies the job of SCADA (Supervisory Control and Data Acquisition) system integrators by providing familiar protocols for retrieving RUGGEDCOM device information. ModBus provides mostly read-only status information, but there are some writable registers for operator commands.
The ModBus protocol PDU (Protocol Data Unit) format is as follows:
Function Code Data
The following sections describe the support for ModBus management:
• Section 1.7.1, “ModBus Function Codes”
• Section 1.7.2, “ModBus Memory Map”
• Section 1.7.3, “ModBus Memory Formats”
