Secure Computing is incorporating three new signature file types for SCADA-specific protocols into its Secure Firewall. SCADA (Supervisory Control and Data Acquisition) systems are used by energy, water, oil/gas, and chemical companies to control critical network components.
Here are the three new SCADA signature types being provided by Secure Firewall:
SCADA:ICCP: The Inter-Control Center Communications Protocol (ICCP or IEC 60870-6/TASE.2) is being specified by utility organizations throughout the world to provide data exchange over wide area networks (WANs) between utility control centers, utilities, power pools, regional control centers, and Non-Utility Generators.
SCADA:MODBUS: Modbus is a serial communications protocol for use with its programmable logic controllers (PLCs). It has become a de facto standard communications protocol in the industry, and is now the most commonly available means of connecting industrial electronic devices.
SCADA:DNP3.0: DNP3.0 (Distributed Network Protocol) is a set of communications protocols used between components in process automation systems. Its main use is in utilities such as electric and water companies. Specifically, it was developed to facilitate communication between various types of data acquisition and control equipment.
