A SCADA system gathers information, such as where a leak on a pipeline has occurred, transfers the information back to a central site, alerting the home station that the leak has occurred, carrying out necessary analysis and control, such as determining if the leak is critical, and displaying the information in a logical and organized fashion. SCADA systems can be relatively simple, such as one that monitors environmental conditions of a small office building, or incredibly complex, such as a system that monitors all the activity in a nuclear power plant or the activity of a municipal water system.

Provides the knowledge to analyse, specify and debug SCADA systems, covering the fundamentals of hardware, software and the communications systems that connect SCADA operator stations
Experts agree, though it is already important, nuclear power will soon be critical to the maintenance of contemporary society. With the heightened importance of nuclear energy comes a heightened threat of terrorism. The possibility of nuclear energy infrastructure terrorism-that is, the use of weapons to cause damage to the nuclear energy industrial sector, which would have widespread, devastating effects-is very real. In Nuclear Infrastructure Protection and Homeland Security, authors Frank R. Spellman and Melissa L. Stoudt present all the information needed for nuclear infrastructure employers and employees to handle security threats they must be prepared to meet. The book focuses on three interrelated nuclear energy infrastructure segments: nuclear reactors, radioactive materials, and nuclear waste. It presents common-sense methodologies in a straightforward manner, so the text is accessible even to those with little experience with nuclear energy who are nonetheless concerned about the protection of our nuclear infrastructure. Important safety and security principles are outlined, along with security measures that can be implemented to ensure the safety of nuclear facilities.
In September 2010, media reports emerged about a new form of cyber attack that appeared to target Iran, although the actual target, if any, is unknown. Through the use of thumb drives in computers that were not connected to the Internet, a malicious software program known as Stuxnet infected computer systems that were used to control the functioning of a nuclear power plant. Once inside the system, Stuxnet had the ability to degrade or destroy the software on which it operated. This book examines the discovery of the Stuxnet worm which has raised several issues for Congress, including the effect on national security, what the government’s response should be, whether an international treaty to curb the use of malicious software is necessary, and how such a treaty could be implemented.
The United States, our allies, and our partners face a spectrum of challenges, including violent transnational extremist networks, hostile states armed with weapons of mass destruction, rising regional powers, emerging space and cyber threats, natural and pandemic disasters, and a growing competition for resources. The Department of Defense must respond to these challenges while anticipating and preparing for those of tomorrow. We must balance strategic risk across our responses, making the best use of the tools at hand within the U.S. Government and among our international partners. To succeed, we must harness and integrate all aspects of national power and work closely with a wide range of allies, friends and partners. We cannot prevail if we act alone.
As noted in the 2006 QDR, state actors no longer have a monopoly over the catastrophic use of violence. Small groups or individuals can harness chemical, biological, or even crude radiological or nuclear devices to cause extensive damage and harm. Similarly, they can attack vulnerable points in cyberspace and disrupt commerce and daily life in the United States, causing economic damage, compromising sensitive information and materials, and interrupting critical services such as power and information networks. National security and domestic resources may be at risk, and the Department must help respond to protect lives and national assets. The Department will continue to be both bulwark and active protector in these areas. Yet, in the long run the Department of Defense is neither the best source of resources and capabilities nor the appropriate authority to shoulder these tasks. The comparative advantage, and applicable authorities, for action reside elsewhere in the U.S. Government, at other levels of government, in the private sector, and with partner nations. DoD should expect and plan to play a key supporting role in an interagency effort to combat these threats, and to help develop new capacities and capabilities, while protecting its own vulnerabilities.
In the contemporary strategic environment, the challenge is one of deterring or dissuading a range of potential adversaries from taking a variety of actions against the U.S. and our allies and interests. These adversaries could be states or non-state actors; they could use nuclear, conventional, or unconventional weapons; and they could exploit terrorism, electronic, cyber and other forms of warfare. Economic interdependence and the growth of global communications further complicate the situation. Not only do they blur the types of threats, they also exacerbate sensitivity to the effects of attacks and in some cases make it more difficult to attribute or trace them. Finally, the number of potential adversaries, the breadth of their capabilities, and the need to design approaches to deterrence for each, create new challenges.
An underlying assumption in our understanding of the strategic environment is that the predominant near-term challenges to the United States will come from state and non-state actors using irregular and catastrophic capabilities. Although our advanced space and cyber-space assets give us unparalleled advantages on the traditional battlefield, they also entail vulnerabilities.
China is developing technologies to disrupt our traditional advantages. Examples include development of anti-satellite capabilities and cyber warfare. Other actors, particularly non-state actors, are developing asymmetric tactics, techniques, and procedures that seek to avoid situations where our advantages come into play.
In September 2010, media reports emerged about a new form of cyber attack that appeared to target Iran, although the actual target, if any, is unknown. Through the use of thumb drives in computers that were not connected to the Internet, a malicious software program known as Stuxnet infected computer systems that were used to control the functioning of a nuclear power plant. Once inside the system, Stuxnet had the ability to degrade or destroy the software on which it operated. Although early reports focused on the impact on facilities in Iran, researchers discovered that the program had spread throughout multiple countries worldwide.
From the perspective of many national security and technology observers, the emergence of the Stuxnet worm is the type of risk that threatens to cause harm to many activities deemed critical to the basic functioning of modern society. The Stuxnet worm covertly attempts to identify and exploit equipment that controls a nation’s critical infrastructure. A successful attack by a software application such as the Stuxnet worm could result in manipulation of control system code to the point of inoperability or long-term damage. Should such an incident occur, recovery from the damage to the computer systems programmed to monitor and manage a facility and the physical equipment producing goods or services could be significantly delayed. Depending on the severity of the attack, the interconnected nature of the affected critical infrastructure facilities, and government preparation and response plans, entities and individuals relying on these facilities could be without life sustaining or comforting services for a long period of time. The resulting damage to the nation’s critical infrastructure could threaten many aspects of life, including the government’s ability to safeguard national security interests.
Iranian officials have claimed that Stuxnet caused only minor damage to its nuclear program, yet the potential impact of this type of malicious software could be far-reaching. The discovery of the Stuxnet worm has raised several issues for Congress, including the effect on national security, what the government’s response should be, whether an international treaty to curb the use of malicious software is necessary, and how such a treaty could be implemented. Congress may also consider the government’s role in protecting critical infrastructure and whether new authorities may be required for oversight.
