This SpringerBrief explores features of digital protocol wireless communications systems, and features of the emerging electrical smart grid. Both low power and high power wireless systems are described. The work also examines the cybersecurity vulnerabilities, threats and current levels of risks to critical infrastructures that rely on digital wireless technologies. Specific topics include areas of application for high criticality wireless networks (HCWN), modeling risks and vulnerabilities, governance and management frameworks, systemic mitigation, reliable operation, assessing effectiveness and efficiency, resilience testing, and accountability of HCWN. Designed for researchers and professionals, this SpringerBrief provides essential information for avoiding malevolent uses of wireless networks. The content is also valuable for advanced-level students interested in security studies or wireless networks.

Many international terrorist groups now actively use computers and the Internet to communicate, and several may develop or acquire the necessary technical skills to direct a co-ordinated attack against computers in the United States. A cyberattack intended to harm the U.S. economy would likely target computers that operate the civilian critical infrastructure and government agencies. However, there is disagreement among some observers about whether a co-ordinated cyberattack against the U.S. critical infrastructure could be extremely harmful, or even whether computers operating the civilian critical infrastructure actually offer an effective target for furthering terrorists' goals. While there is no published evidence that terrorist organisations are currently planning a co-ordinated attack against computers, computer system vulnerabilities persist world-wide, and initiators of the random cyberattacks that plague computers on the Internet remain largely unknown. Reports from security organisations show that random attacks are now increasingly implemented through use of automated tools, called "bots", that direct large numbers of compromised computers to launch attacks through the Internet as swarms. The growing trend toward the use of more automated attack tools has also overwhelmed some of the current methodologies used for tracking Internet cyberattacks. This book provides background information for three types of attacks against computers (cyberattack, physical attack, and electromagnetic attack), and discusses related vulnerabilities for each type of attack. The book also describes the possible effects of a co-ordinated cyberattack, or computer network attack (CNA), against U.S. infrastructure computers, along with possible technical capabilities of international terrorists. Issues for Congress may include how could trends in cyberattacks be measured more effectively; what is appropriate guidance for DOD use of cyberweapons; should cybersecurity be combined with, or remain separate from, the physical security organization within DHS; how can commercial vendors be encouraged to improve the security of their products; and what are options to encourage U.S. citizens to follow better cybersecurity practices? Appendices to this book describe computer viruses, spyware, and "bot networks", and how malicious programs are used to enable cybercrime and cyberespionage. Also, similarities are drawn between planning tactics currently used by computer hackers and those used by terrorists groups for conventional attacks.

Persistent computer security vulnerabilities may expose U.S. critical infrastructure and government computer systems to possible cyber attack by terrorists, possibly affecting the economy or other areas of national security. This report discusses possible cyber capabilities of terrorists and sponsoring nations, describes how computer security vulnerabilities might be exploited through a cyber terror attack, and raises some potential issues for Congress.

Currently no evidence exists that terrorist organizations are actively planning to use computers as a means of attack, and there is disagreement among some observers about whether critical infrastructure computers offer an effective target for furthering terrorists' goals. However, terrorist organizations now use the Internet to communicate, and news reports have indicated that Al Qaeda and other groups may be using computer technology to help plan future terrorist attacks. At the same time, nuisance attacks against computer systems and the Internet are becomingmore rapid and widespread, indicating that computer system vulnerabilities persist despite growing concerns about possible effects on national security.

This report presents a working definition for the term "cyber terrorism," plus background information describing how current technology and management processesmay leave computers exposed to cyber attack, and a discussion of possible effects of a cyber attack. ...

Network Centric Warfare (NCW) is a key component of DOD planning for transformation of the military. NCW relies on computer processing power and networked communications technology to provide a shared awareness of the battle space for U.S. forces. Proponents say that a shared awareness increases synergy for command and control, resulting in superior decision-making, and the ability to coordinate complex military operations over long distances for an overwhelming war-fighting advantage. NCW technology saw limited deployment in Afghanistan and, more recently, increased deployment in Operation Iraqi Freedom (OIF). Several DOD key programs are now underway for deployment throughout all services. Congress may be concerned with oversight of the DOD organization and the individual services as they transform through NCW programs that are intended to promote a management style and culture with joint objectives. Oversight may involve a review of service efforts to improve interoperability of computer and communications systems, and may also involve questions from some observers about whether DOD has given adequate attention to possible unintended outcomes resulting from over-reliance on high technology. Updates may also be required on emerging threats that may be directed against increasingly complex military equipment. The background section of this report describes technologies that support ...

Cybercrime is becoming more organized and established as a transnational business. High technology online skills are now available for rent to a variety of customers, possibly including nation states, or individuals and groups that could secretly represent terrorist groups. The increased use of automated attack tools by cybercriminals has overwhelmed some current methodologies used for tracking Internet cyberattacks, and vulnerabilities of the U.S. critical infrastructure, which are acknowledged openly in publications, could possibly attract cyberattacks to extort money, or damage the U.S. economy to affect national security. In April and May 2007, NATO and the United States sent computer security experts to Estonia to help that nation recover from cyberattacks directed against government computer systems, and to analyze the methods used and determine the source of the attacks.1 Some security experts suspect that political protestors may have rented the services of cybercriminals, possibly a large network of infected PCs, called a "botnet," to help disrupt the computer systems of the Estonian government. DOD officials have also indicated that similar cyberattacks from individuals and countries targeting economic, political, and military organizations may increase in the future.2 Cybercriminals have reportedly made alliances with drug traffickers in Afghanistan, the Middle East, and elsewhere ...

Electromagnetic Pulse (EMP) is an instantaneous, intense energy field that can overload or disrupt at a distance numerous electrical systems and high technology microcircuits, which are especially sensitive to power surges. A large scale EMP effect can be produced by a single nuclear explosion detonated high in the atmosphere. This method is referred to as High-Altitude EMP (HEMP). A similar, smaller-scale EMP effect can be created using non-nuclear devices with powerful batteries or reactive chemicals. This method is called High Power Microwave (HPM). Several nations, including reported sponsors of terrorism, may currently have a capability to use EMP as a weapon for cyber warfare or cyber terrorism to disrupt communications and other parts of the U.S. critical infrastructure. Also, some equipment and weapons used by the U.S. military may be vulnerable to the effects of EMP. The threat of an EMP attack against the United States is hard to assess, but some observers indicate that it is growing along with worldwide access to newer technologies and the proliferation of nuclear weapons. In the past, the threat of mutually assured destruction provided a lasting deterrent against the exchange of multiple high-yield nuclear warheads. However, now even a single, speciallydesigned low-yield nuclear ...
