Ruggedcom Crossbow

02 February 2024 Product News

RUGGEDCOM CROSSBOW stands as an advanced secure remote access management solution at the enterprise level, specifically crafted to aid in NERC CIP and IEC 62443 compliant access to Intelligent Electronic Devices (IEDs).

CROSSBOW is tailored to meet the utilities' requirement to interactively access remote field IEDs for tasks like maintenance, configuration, and data retrieval. It facilitates a seamless connection, allowing a native IED application to communicate remotely with its associated IEDs as if the user were physically connected.

Employing administrator-defined Role Based Access (RBA), CROSSBOW ensures activity logging and data privacy as users establish connections to remote IEDs. The solution incorporates robust two-factor authentication via RSA SecurID, Active Directory, and RADIUS, ensuring the highest level of process security.

CROSSBOW goes beyond mere access and enables the automation of common device management tasks, including password changes, file retrieval, and configuration management. Users have the flexibility to extend or customize CROSSBOW functionalities using scripts and plug-ins, tailoring it to meet their specific requirements.

The distributed architecture of CROSSBOW, featuring the Station Access Controller (SAC) and the Secure Access Manager Local (SAM-L), ensures local and emergency connectivity to IEDs. This architecture provides full support for all automation functions (SAM-L only), even in scenarios where communication is lost between the central CROSSBOW server (Secure Access Manager Primary or SAM-P) and the remote site.

Design

System architecture

The RUGGEDCOM CROSSBOW system consists of a central enterprise server and several clients. The CROSSBOW Secure Access Manager (SAM) server is based on Microsoft SQL Server, contains the system database, and manages all connections from the clients to the remote IEDs. It provides role-based access control, site and IED access management, and supports high availability cluster configuration for increased reliability.

CROSSBOW clients connect to the SAM via secure SSL connections to provide user-access to remote IEDs.

The alternative Application Server architecture also allows for the central management of all native IED applications by locating them on a central server, eliminating the need for client software on the user’s desktop.

The CROSSBOW client-server architecture is designed to be scaled to the needs of small, medium, and large utilities while maintaining peak performance to its entire population of field IEDs.

RUGGEDCOM CROSSBOW - system architecture

System components

CROSSBOW Secure Access Manager – Primary – SAM-P

The Secure Access Management (SAM) server verifies the authenticity of the user, either through a personal username and password login (basic security), or through interaction with a corporate security system (strong authentication), to establish the Role-Based Access Control permissions. It runs on an enterprise-grade Windows server platform, either on dedicated hardware or a virtual machine.

CROSSBOW Station Access Controller – SAC (optional)

CROSSSBOW offers local and emergency connectivity through its optional Station Access Controller (SAC), which can be installed at the local or substation level. The CROSSBOW SAC provides the same level of command control and logging when a user is physically present in the station, even when there is loss of communication path between the central SAM and the remote site. CROSSBOW SAC is completely synchronized with the CROSSBOW SAM server. The SAC may run directly on ROX (e.g., on a RUGGEDCOM RX1500/RX5000) or on the RUGGEDCOM APE1808 module.

CROSSBOW Secure Access Manager Local – SAM-L (optional)

The RUGGEDCOM CROSSBOW Secure Access Manager – Local (SAM-L) is a “lite” version of the SAM-P, and is intended for deployment on machines in facility locations. Its purpose is to allow local connectivity and to perform special operations on behalf of the SAM-P on the devices in that facility. SAM-L is installed on a device physically located within the facility, and acts as a local version of the RUGGEDCOM CROSSBOW Server. It can be run from a Windows PC or the RUGGEDCOM APE1808 module.

RUGGEDCOM CROSSBOW – Ensuring High Availability

The RUGGEDCOM CROSSBOW Server or the SAM-P can be licensed to make use of multiple servers configured as a cluster. This allows multiple servers to exist as a single entity, allowing more users to utilize the system at the same time and for faster processing of automated tasks, such as fault record retrieval.

RUGGEDCOM CROSSBOW Application Modules

RUGGEDCOM CROSSBOW Application Modules (CAMs) are separately licensed “plug ins”, which may be added to a CROSSBOW server. CAMs are run by the CROSSBOW scheduler, and may run at the following times:

  • On demand, when invoked by a user with rights to do so
  • On a periodic, scheduled basis

Configuration management CAM

The configuration management CAM connects to managed devices, reads their settings, and compares them to their latest approved baseline. Any variation from the baseline results in an alert.

Firmware version CAM

The firmware version CAM connects to managed devices, reads the firmware version, and compares the devices’ current value to the values expected for that device. Any variation from the baseline results in an alert.

IED data retrieval CAM

Fault and event data collection is performed by the IED data retrieval CAM. CROSSBOW can gather the following data from IEDs:

  • Target status
  • Sequence of Events (SOE) data
  • Fault reports
  • Oscillography files

All gathered data is stored in the CROSSBOW database, along with the time and date it was last updated.

Connectivity CAM

The Connectivity CAM is designed to automate the monitoring of connectivity (i.e., CROSSBOW’s ability to connect to the devices in its database). The intent to ensure that any given end device remains available for other CROSSBOW communications (e.g., end user connections, other CAMs, etc.) and to alert an administrator when it is not.

Time Sync CAM

The Time Sync CAM connects to managed devices, reads the current timestamp, and compares it to the system time on the CROSSBOW server. It raises an alert if the difference is greater than the configured value. Enabled for GE UR relays and SEL relays.

Event Log Distribution Service (ELDS)

The Event Log Distribution Service provides distribution of event information to external tracking systems:

  • Windows Event Log
  • Syslog
  • EMAIL

Flexible rule-based notification profiles match items in the CROSSBOW event log for distribution.

External Database Integration Service (EDIS)

The External Database Integration Service allows CROSSBOW to share device/gateway information with a secondary, external SQL database. During operation, CROSSBOW polls the external database at user-specified intervals for new network-based devices and gateways.

File Export Service

The File Export Service allows CROSSBOW to export CAM files to an external SFTP server:

  • Updated config files as detected and retrieved by the Config CAM
  • New fault and event files as detected and retrieved by the Data CAM
