Continued from How Stuxnet (PLC virus) spreads – Part 3 » Read here Propagation to other Perimeter Network Computers Once the worm has a foothold in the Perimeter Network, it would attempt to infect any print servers and file servers it could discover. Next, the worm would identify the WinCC software installed on the Web …

Continued from How Stuxnet (PLC virus) spreads – Part 2 » Read here Compromising the Network Given the well-secured industrial control system described above, how could a worm like Stuxnet ever penetrate all the way to the PLCs? Yet clearly it did – Siemens reports that it is aware of at least 22 sites that experienced …
How Stuxnet (PLC virus) spreads – Part 2
Continued from How Stuxnet (PLC virus) spreads – Part 1 » Read here Stuxnet is a computer worm designed to infect Siemens SIMATIC WinCC and S7 PLC products, either installed as part of a PCS 7 system, or operating on their own. It starts by taking advantage of vulnerabilities in the Windows operating systems and …
How Stuxnet (PLC virus) spreads – Part 1
The Stuxnet worm is a sophisticated piece of computer malware designed to sabotage industrial processes controlled by Siemens SIMATIC WinCC and PCS 7 control systems. The worm used both known and previously unknown vulnerabilities to install, infect and propagate, and was powerful enough to evade state-of-the-practice security technologies and procedures. Since its discovery, there has …
SCADA communication vulnerabilities
Cyber security engineering is expensive. However, the presence of vulnerabilities requires it. In this section we list vulnerabilities we typically see in SCADA systems. The order in the list of vulnerabilities does not reflect a priority in terms of likelihood of occurrence or severity of impact. Typical vulnerabilities in SCADA systems are listed below. The …
Wind Turbine Control and Operation with Ovation SCADA
Wind is an infinitely renewable supply of power that can be harnessed as an outstanding energy source given the proper location and use of the latest turbine generation technology. Major power producers world-wide have adopted wind power, a clean source of energy that can last up to 20 years or more, as an economically viable …
iFIX Scada Features
iFIX offers a robust SCADA engine, rich set of connectivity options, open architecture and highly scalable and distributed networking model. Used in a variety of applications across diverse industries, it is ideally suited for applications as simple as typical HMI applications such as manual data entry and validation to very complex SCADA applications like batching, …
Security for Substation Communications
Until recently the term “security,” when applied to SCADA communication systems, meant only the process of ensuring message integrity in the face of electrical noise and other disturbances to the communications. But, in fact, “security” also has a much broader meaning. Security, in the broader sense, is concerned with anything that threatens to interfere with …
SCADA Security Attacks
SCADA systems are used to control and monitor physical processes, examples of which are transmission of electricity, transportation of gas and oil in pipelines, water distribution, traffic lights, and other systems used as the basis of modern society. The security of these SCADA systems is important because compromise or destruction of these systems would impact …
