Wireless LANs can be found nearly everywhere today. Most mobile computers ship with built-in wireless LAN hardware by default and most other computers can be equipped with additional hardware. Because all data is transmitted wirelessly, extra security is needed in these networks. This was a concern to the creators of the IEEE 802.11 standard, who designed a simple protocol called WEP which stands for Wired Equivalent Privacy to protect such networks. Unfortunately, the WEP protocol has some serious design flaws and various attacks are possible against WEP protected networks. This book presents nearly all currently known attacks on the WEP protocol, including their theoretical background and their implementation. This book is intended for network operators, who want to learn more about wireless security, and also for cryptographers, who want to understand the theoretical background of these attacks.

Today, the Internet is entering a new stage which will have a much stronger impact on the daily lives of all kinds of organizations. The next communication paradigm offers an improved access to mobility information, offering people and all organizations that deal with mobile devices the ability to access information whenever and wherever necessary. We really are at the edge of a new technological revolution, based on the ubiquity of information through the use of mobile devices and telecommunications. Furthermore, historical tendencies lead us to believe that the impact both on people and on organizations of this technological wave will be both faster and more powerful than any previous one. To the individual, information ubiquity results in the necessity to have immediate access to information. The strategic tactic and operational impact in organizations will therefore be incomparably deeper than in previous organizational management change using technology such as total quality management or business process re-engineering.

Today, our entire modern way of life, from communication to commerce to conflict, fundamentally depends on the Internet. And the cybersecurity issues that result challenge literally everyone. We face new questions in everything from our rights and responsibilities as citizens of both the online and real world to simply how to protect ourselves and our families from a new type of danger. The key question areas of cyberspace and its security: how it all works, why it all matters, and what can we do?
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.

Has the Stuxnet worm ushered in a new era of cyberwar, or is it simply the latest iteration of familiar strategic instruments? Has the Internet irrevocably shifted the balance between individuals and states, or will governments adapt to regain the upper hand? Does the real threat to cybersystems lie within cyberspace, or in the real world? Cyberwar has become a permanent feature of the strategic landscape, but we might hardly know it.
