This document discusses the vulnerability of communication and information networks to electromagnetic pulses (EMPs). It defines key terms like EMP, electromagnetic vulnerability, electromagnetic interference, and the electromagnetic spectrum. It explains that EMPs come from nuclear explosions and can disrupt electronics for hundreds of miles. An EMP attack could damage critical infrastructure systems in sectors like emergency services, energy, and finance. Hardening equipment and networks can help mitigate vulnerabilities, but an EMP blast over the US could still impact most of the country and potentially collapse major systems.
Eelctro-Magnetic-Pulse USE AS A WEAPONAshutosh Uke
Seminar Report File - High Power Electromagnetic Pulse generation techniques and High Power Microwave technology have matured to the point where practical EMP Weapon (Electromagnetic pulse) are becoming technically feasible, with new applications in both Strategic and Tactical Information Warfare. The development of conventional EMP devices allows their use in non-nuclear confrontations. This paper discusses aspects of the technology base, weapon delivery techniques and proposes a doctrinal foundation for the use of such devices in warhead and bomb applications.
1) An EMP attack from a high-altitude nuclear detonation could have a catastrophic impact on the US by disrupting critical infrastructure systems.
2) The document assesses that the electric power grid, telecommunications, transportation, and other infrastructure sectors are highly vulnerable to EMP and interdependent, so that the failure of one could collapse others.
3) Recovery from a major EMP attack that causes wide-scale infrastructure damage could take months or years due to difficulties obtaining replacement parts and lack of spare equipment for critical systems like large power transformers.
An electromagnetic pulse (EMP) is a short burst of electromagnetic energy that can disrupt or damage electronic equipment. The document discusses how EMPs are generated through high altitude nuclear explosions or intentional electromagnetic interference devices. It also outlines some protection measures like using surge protectors, Faraday cages, and disconnecting equipment to reduce vulnerabilities from EMP attacks.
Electromagnetic pulse (EMP) weapons can be created through two methods - high-altitude electromagnetic pulse (HEMP) using a nuclear explosion high in the atmosphere, and high-power microwave (HPM) using non-nuclear methods. HEMP produces gamma radiation that interacts with the atmosphere to create an intense EMP field over a large area, potentially thousands of miles. HPM uses chemical explosions or batteries to generate focused microwaves that can disrupt electronics over a smaller area of around 1 mile. While HEMP requires nuclear weapons, HPM has lower technological requirements and could potentially be developed by non-state actors.
The document discusses electromagnetic fields and their interactions with biological systems. It describes how electromagnetic waves are characterized by their wavelength, frequency, and energy. Non-ionizing radiation cannot cause ionization but can produce biological effects like heating or inducing electrical currents. The World Health Organization's International EMF Project addresses health concerns from radiofrequency, extremely low frequency, and static electric and magnetic fields, which can produce biological effects that may lead to health consequences.
This document provides an overview of safety and security topics related to basic industrial wiring. It discusses the physiological effects of electricity on the human body, including how electric current can cause heating, damage nerves and tissues. Threshold values for electric sensation, the ability for a person to let go, and ventricular fibrillation are defined. The main causes of electric shocks are also examined, such as inappropriate operating modes, lack of awareness of risks, and inadequate training. Formulas are provided to calculate body impedance and the current that will flow through the body depending on voltage exposure. The various effects of electric current on the body are also summarized.
The document summarizes an undergraduate seminar report on electromagnetic bombs (e-bombs). It discusses the basic principle of electromagnetic pulse (EMP) effects and how they can damage electronics.

An electromagnetic bomb, or E-bomb, is a weapon that generates a powerful electromagnetic pulse capable of disabling electronics over a wide area without harming people. It works by using an explosively-pumped flux compression generator or high power microwave device to generate an intense electromagnetic burst. This electromagnetic pulse induces damaging voltages in exposed wiring and circuitry. While an E-bomb could knock out power grids and communication systems across an entire coast, it has limitations in accuracy and risks harming medical equipment. There is ongoing research focused on developing more advanced E-bomb technologies and defenses against electromagnetic weapons.

An electromagnetic pulse (EMP) weapon called an E-bomb is proposed. It could destroy power grids, electronics, and communication systems over an entire coast while sparing humans and other living species. The E-bomb works by generating an intense electromagnetic burst using either a flux compression generator or a virtual cathode oscillator. This would overwhelm and damage the electric circuitry of targeted systems. Delivery could be via cruise missile, aircraft, or air-to-air missile. While an effective weapon, E-bombs would be difficult to implement accurately and their effects hard to assess. Defenses would require comprehensive electromagnetic shielding.
The Failure of Public Health. A Case Study final 12-19-15Lloyd Morgan
This document discusses the failure of public health efforts in addressing extremely low frequency (ELF) magnetic fields in California schools. ELF magnetic fields have been declared a possible human carcinogen and levels above 2mG increase cancer risks, yet 11.6% of areas in California schools measured over 2mG in 1996 due to "net current problems" in wiring. Fixing this wiring issue costs an average of $6,800 per school but authorities have not enforced regulations to address it despite knowing of the problem for years. This inaction stands in contrast to regulations requiring ground-fault circuit breakers to prevent electrocutions, demonstrating inconsistencies in U.S. public health priorities when it comes to reducing cancer risks from ELF

The document also covers geopathic stress from underground structures distorting natural electromagnetic fields, and its health impacts. It proposes using Enviro Chips to change the harmful nature of these radiations rather than reduce radiation levels, as measured by instruments.
Electromagnetic pulse generator(emp bomb) raja sukumar
This document describes the design and operation of an electromagnetic pulse (EMP) generator. The EMP generator consists of two circuits - one to store energy from a wall outlet using a capacitor, and another to release this energy through a loop of wire, generating an electromagnetic pulse. The purpose of the EMP is to electrically destroy electronics through rapidly heating semiconductor materials. Safety precautions are required when working with the high voltages involved. Further research could optimize EMP effects and electronic shielding.
An electromagnetic bomb or E-bomb is designed to disable electronics with an electromagnetic pulse. Key technologies that can be applied to E-bomb designs include explosively pumped flux compression generators, explosive or propellant driven MHD generators, and various high-power microwave devices. Explosively pumped flux compression generators are the most mature technology, using explosives to rapidly compress magnetic fields to produce high currents. E-bombs can effectively couple with and damage electronics through wiring and cables. Low frequency E-bombs couple well into typical infrastructure wiring. Targets can include communications sites and mobile air defense equipment. Hardening systems against EMPs is an important defense. E-bombs have limitations based on delivery accuracy and range against the target damage

It then acknowledges those who provided input and reviews key aspects of EMP bombs, including their effects on electronics, the technology involved in their design, such as flux compression generators and virtual cathodes, and considerations for targeting EMP bombs.
The document discusses the electromagnetic bomb (E-bomb) and how it works. An E-bomb produces a high-powered electromagnetic pulse through a flux compression generator. It destroys electronics and communication systems by knocking electrons loose from atoms. Key components include a metal cylinder filled with explosive that generates an electromagnetic burst when detonated. E-bombs are useful for disabling technology but cause little damage to life. Protection requires Faraday cages and shielding of critical systems.
The document discusses e-bombs, which are electromagnetic weapons that use high-powered microwave pulses to disable electronic equipment through mechanisms like the Compton effect without harming human life. E-bombs work by generating intense electromagnetic bursts using explosively pumped flux compression generators that can effectively paralyze military and civilian communication, computer and sensor systems. While e-bombs provide a potentially less lethal alternative to conventional weapons, they still pose risks such as endangering patients reliant on electronic medical equipment.
Analysis of electromagnetic pollution due to high voltage transmission linesAlexander Decker
This document analyzes electromagnetic pollution from high voltage power transmission lines in Nigeria. It measures electric and magnetic field levels from 132kV and 330kV lines in Bauchi and Gombe areas. Field measurements were taken within 450m horizontally and 1.5m vertically from the lines. Measured field levels for both general public and occupational exposures were found to be within safety limits set by ICNIRP. The highest magnetic field measured was 45mG and 100mG for public and occupational exposures, respectively. The highest electric fields were 130V/m for both exposure groups. These levels represent a small percentage of ICNIRP safety limits.
EMI refers to electromagnetic interference, or unwanted electromagnetic signals that can disrupt other electronic devices. EMC refers to electromagnetic compatibility, which is the ability of a device to function properly without disrupting or being disrupted by other electromagnetic signals. Electronic products must meet EMI and EMC standards before being released to ensure they do not interfere with other devices and are not interfered with themselves. Following design guidelines and using EMI-compliant components can help products pass EMI/EMC tests on the first try.

The E-bomb produces a high beam of electromagnetic waves using explosively pumped flux compression generators.

While dangerous to technology, E-bombs pose less risk to human life than conventional weapons.
The document discusses the E-bomb, or electromagnetic pulse bomb, which is a non-lethal weapon that emits an electromagnetic pulse capable of disabling electronics within its radius. It works by generating a powerful electromagnetic field that induces damaging voltages on electrical systems. The key components of an E-bomb are an explosively pumped flux compression generator to produce the pulse, and antennas to broadcast it. E-bombs could neutralize systems like vehicles, weapons, communications and more while sparing human life. However, they also have limitations related to delivery and risks for those relying on medical devices.
An electromagnetic pulse (EMP) bomb, or E-bomb, is a non-lethal weapon that uses electromagnetic pulses to disable electrical circuitry within a radius. It works by generating an intense electromagnetic field from a flux compression generator powered by an explosive charge. This pulse induces surges in electronics that overwhelm and destroy semiconductor devices. E-bombs could knock out power grids and communication systems over a large area but spare human life. While useful for disabling infrastructure, E-bombs have limitations in accuracy and risk harming medical devices. Protection requires hardening sites and equipment against EMP effects.
Fundamentals of electromagnetic compatibility (EMC)Bruno De Wachter
Electromagnetic interference, EMI, has become very important in the last few decades as the amount of electronic equipment in use has increased enormously. This has led to an increase in the sources of interference, e.g. digital equipment and switching power supplies, and an increase in the sensitivity of equipment to interference, due to higher data rates.
This development demands high quality electrical installations in all buildings where electromagnetic non-compatibility leads to either higher costs or to an unacceptable decrease in safety standards.
This application note gives an overview and a basic understanding of the major physical principles of electromagnetic interference and an introduction to the principles of mitigation of disturbing effects. As a result, the measures required to achieve an EMC-compliant installation should be easily understood.

The main sections cover the mechanisms of lightning, its direct and indirect effects, and methods for protecting structures from lightning. Direct effects include damage from the lightning current itself. Indirect effects involve overvoltages induced in wiring from lightning strikes via conduction, induction, or increased earth potential. Protection methods center on intercepting lightning strikes with conductors and safely directing current to ground.

Abstract
Communications and information networks are vulnerable to natural disasters and physical
attacks using electromagnetic pulse (EMP). Real world problems occur in specific locations
throughout the world which interfere with parts of the information and communications networks
which are used in all sixteen critical infrastructure sectors listed and described on the Department
of Homeland Security official web site. This paper examines the vulnerability of the information
and communications networks to EMP used by the emergency services, energy and financial
sectors in the United States. This research paper aims to discuss countermeasures to mitigate the
negative impacts of an electromagnetic pulse to include the definition of EMP, electromagnetic
compatibility (EMC), electromagnetic vulnerability (EMV), electromagnetic interference (EMI)
and the electromagnetic spectrum. The purpose of this paper is to educate through research in
reference to the vulnerabilities of information and communication networks to EMP and ways to
mitigate the effects of EMP events.
Keywords: Electromagnetic pulse (EMP), electromagnetic vulnerability (EMV), electromagnetic
interference (EMI), electromagnetic compatibility (EMC) and electromagnetic spectrum.

Cyber Vulnerability in Electromagnetic Pulse
Introduction
This research explains the effects of an electromagnetic pulse (EMP) attack and the impact
on the emergency services, financial and energy sectors. The results of this research will show
the prominent cyber vulnerabilities to an EMP attack on these sectors and the use of technology
such as EMP hardening of communications and data networks and equipment to counter the
effects of an EMP attack. Several key terms must be addressed. These key terms are important
to have an understanding of the research in this paper. Electromagnet pulse (EMP) is a main
element of cyber vulnerability to EMP. EMP is the electromagnetic radiation from a nuclear
explosion caused by Compton-recoil electrons and photoelectrons from photons scattered in the
materials of the nuclear device or in a surrounding medium. Electromagnetic vulnerability
(EMV) is the characteristics of a system that cause it to suffer a definite degradation as a result of
having been subjected to a certain level of electromagnetic environmental effects.
Electromagnetic interference (EMI) is any electromagnetic disturbance that interrupts, obstructs,
or otherwise degrades or limits the effective performance of electronics and electrical equipment.
Electromagnetic compatibility (EMC) is the ability of systems, equipment, and devices that
utilize the electromagnetic spectrum to operate in their intended operational environments
without suffering unacceptable degradation or causing unintentional degradation because of
electromagnetic radiation or response (Defense Acquisition University, 2007). The
electromagnetic spectrum is the complete range of wavelengths from the longest radio waves and
extending through visible light all the way to the extremely short gamma rays (Musey, 2013).
Technology in the modern day has grown and is growing at an exponential rate making it
technically difficult to protect information and critical infrastructure which creates the potential
4. CYBER VULNERABILITY IN ELECTROMAGNETIC PULSE 4
for cyber vulnerabilities to electromagnetic pulse. Nuclear explosions and non-nuclear
electromagnetic pulse weapons create a high energy pulse of electrical and magnetic energy that
disrupts electronics and power grids for hundreds of miles. A high altitude electromagnetic
pulse (HEMP) releases energy in the form of gamma rays. Gamma rays collide with molecules
of air and produce Compton electrons (Ullrich, 1997). These electrons interact with the earth’s
magnetic field and produce an electromagnetic pulse which propagates in the downward
direction to the earth’s surface. The initial gamma rays and EMP move at the speed of light.
The effects of the EMP encompass an area along the line of sight from the point of detonation to
the earth’s horizon. Any systems that are in view of the detonation will experience some degree
of EMP.
An electromagnetic pulse consists of three components which are E1, E2 and E3. The E1
component is a free field energy pulse that occurs in a fraction of a second. The generated
electromagnetic shock damages, disrupts and destroys electronics and electronic systems in a
near simultaneous timeframe over a very large area. Faraday cage protection and other
mechanisms designed to defend against lighting strikes will not withstand this assault. Only
specialized technology integrated into equipment can harden the equipment against EMP. When
the electromagnetic distortion is large enough the E1 shock will destroy lightly EMP shielded
equipment in addition to most consumer electronics. Devices that incorporate antennas and
accept electronic signals cannot be shielded against E1. The result will be the destruction of
trillions of dollars of electronics that will fail after an EMP assault regardless of protective
measures. The E1 component is particularly concerning since it destroys Supervisory Control
and Data Acquisition (SCADA) components that are critical to the United States’ national
infrastructures.
5. CYBER VULNERABILITY IN ELECTROMAGNETIC PULSE 5
The E2 component covers the same area as E1 but is more geographically widespread but
has a lower amplitude than E1. The E2 component has similar effects as lightning. E2 is not a
critical threat to critical infrastructure since most systems have built in protection against
occasional lightning strikes. The E2 threat compounds the E1 component since it strikes a
fraction of a second after the E1 component has damaged or destroyed the protective devices that
would have prevented damage from the E2 component. The result is that the E2 component
typically inflicts more damage than E1 since it bypasses traditional protective measures and
greatly amplifies the damage inflicted by the EMP.
The E3 component is a longer duration pulse the lasts up to one minute. It disrupts long
electricity transmission lines and causes damage to the electrical supply and distribution systems
connected to these lines. The E3 component of EMP is not a freely propagating wave; it is a
result of the electromagnetic distortion in the earth’s atmosphere. In this way the E3 component
is similar to a massive geomagnetic storm and is particularly damaging to long line infrastructure
such as electrical cables and transformers. A moderate blast of E3 could negatively impact up to
seventy percent of the power grid in the United States.
The timing of the three components is an important part of the equation in relation to the
damage that EMP generates. The damage from each strike amplifies the damage caused by each
succeeding strike. The combination of the three components causes irreversible damage to many
electronic systems. With the combined damage from earlier E1 and E2 blasts the E3 component
of the EMP has the potential to destroy the nation’s critical communications and electrical power
grid inflicting catastrophic damage on the United States. The EMP can easily and rapidly span
continent sized areas and can affect systems on land, sea and air. The EMP pulse from a nuclear
burst extends well past the visual horizon as seen from the point of the burst.
6. CYBER VULNERABILITY IN ELECTROMAGNETIC PULSE 6
Figure 1 depicts the EMP area of a burst at an altitude of 30, 120 and 300 miles above the
geographical center of the lower forty-eight states within the United States.

Threats” testimony to House National Security Committee. by: Smith, Gary. Young

The EMP effects vary depending on numerous factors. One of the most important variables
is the altitude of the EMP blast. The most effective altitude to achieve the greatest EMP effect is
for the EMP blast to be above the visible horizon. If the detonation is to low most of the electro-
magnetic force from the EMP will be driven into the ground and create deadly nuclear fallout
that deprives the weapon of its non-casualty appeal. The damage is inversely related to the
7. CYBER VULNERABILITY IN ELECTROMAGNETIC PULSE 7
target’s distance from the epicenter of the detonation. The further away from the EMP blast’s
epicenter the weaker the EMP effects will be. The yield of the nuclear weapon is another factor
to consider. The higher the yield of weapon the greater the effect of the EMP. Even so since the
effects travel through electric lines and waterways and have secondary spill-over impacts on
other critical infrastructure it is technically difficult to predict the full extent of damage from a
large scale EMP attack.
In the event of a high yield weapon being detonated two-hundred-fifty miles above the
United States most if not all of the lower forty-eight states would be in the line of sight of the
detonation. The frequency range of such a detonation has an EMP that ranges from below one
hertz to one gigahertz. All modern types of electronics are at risk from Chicago to New Orleans
and from Los Angeles to Boston. A nuclear atmospheric test of a 1.4 megaton device conducted
by the United States in 1962 two-hundred-forty miles above Johnston Island caused electronic
systems to fail in Hawaii seven-hundred miles away (Ullrich, 1997). Not commonly known
about the effects of a high altitude EMP burst is that of the pumping of a large number of
electrons into the Van Allen A and B belts also known as the inner and outer radiation belts
around the Earth. The bomb induced electrons remain trapped in these belts for a period of time
in excess of one year. Global Position System (GPS) and Low-Earth Orbit (LEO) satellites in
these belts that are not hardened to withstand electrons from a high altitude EMP blast would
meet their demise in a matter of days to weeks after such a blast.
Figure 2 which follows depicts the detonation of a nuclear weapon at a high altitude referred
to as a HEMP as well as the induced Gamma rays into the atmosphere along with the negative
impacts on communications networks and aircraft.

When Gamma and x-rays from a high altitude detonation encounter a satellite in space they
excite and release electrons when the Gamma rays penetrate the interior of the satellite system.
This is referred to as System Generated Electromagnetic Pulse (SGEMP) since the accelerated
electrons create electromagnetic transients. Systems need to be configured with aperture
protection, grounding, special cables and insulating materials to survive the EMP effects.
SGEMP impacts space systems in three ways. The first is the x-rays causing electrons to collect
9. CYBER VULNERABILITY IN ELECTROMAGNETIC PULSE 9
on the skin of the space system. The electron charge is not distributed uniformly over the skin of
the space system which causes current to flow on the outside of the system. The current can
penetrate into the interior of a space system such as a communications satellite by entering
through the various apertures and solar cell power transmission systems. A second way in which
Gamma and x-rays can penetrate the skin of a space system is to produce electrons on the
interior walls of various compartments. The resulting interior electron currents generate cavity
electromagnetic fields that induce voltages on the electronics which produce spurious currents
that can burnout the electronics (Ullrich, 1997). The third way in which SGEMP impact space
systems electronics is the Gamma and x-rays produce electrons that propagate directly into
power and signal cables and wiring harnesses causing extraneous cable currents.
In addition to a high altitude burst producing an EMP there is also a low altitude nuclear
burst that produces a Source Region Electromagnetic Pulse (SREMP). In a low altitude nuclear
burst a vertical electron current is formed by the asymmetric deposition of electrons in the
atmosphere and the ground. The formation and decay of the current emits a pulse of
electromagnetic radiation in directions perpendicular to the current. The asymmetry from a low
altitude nuclear detonation occurs due some of the electrons emitting downward being trapped in
the Earth’s surface. Other electrons move upward and outward and can travel long distances in
the atmosphere producing ionization and charge separation. A SREMP can produce peak
electric fields greater than 100,000 volts per meter and peak magnetic fields greater than 4,000
amperes per meter (Federation of American Scientists, 2014). These are much larger than those
from HEMP and pose a considerable threat to military and civilian systems. The surface of the
Earth is a conductor of electricity and provides a return path for electrons at the outer part of the
deposition region toward the burst point. Positively charge ions travel shorter distances than
10. CYBER VULNERABILITY IN ELECTROMAGNETIC PULSE 10
electrons and at lower velocities and the ions remain behind and recombine with the electrons
returning through the ground. The result is very strong magnetic fields are produced in the
region of ground zero when the nuclear detonation occurs near to the surface of the Earth.
EMP whether from a high or low altitude nuclear burst does not differentiate between power
grids, telecommunication and computing systems. Systems that are not hardened against EMP
such as commercial power grids, computer and telecommunication systems remain vulnerable to
widespread prolonged outages and disruptions. The Homeland Security Science and Technology
Act of 2010 contains provisions for the establishment of a commission on the Protection of
Critical Electric and Electronic Infrastructures which will serve to ensure improvements in EMP
hardening of telecommunication and computing systems and power grids.
EMP Vulnerabilities in Emergency Services Sector
The emergency services sector consists of interacting national, regional, state and local
communications and network systems interconnected over large geographical areas. The
emergency services sector systems are under the control of national, regional and state control
centers. These systems depend upon wireless and fixed communications, broadband, radio
frequencies and fiber optics. Communications and data networks are vulnerable to natural
disasters such as hurricanes, floods, earthquakes and physical attacks such as an electromagnetic
pulse attack. The natural disasters occur in specific geographical areas and disrupt and/or
disables specific parts of the network. An EMP attack on the other hand not only disrupts and
disables communications and data networks it also destroys them permanently over a large
geographical are unless the equipment is hardened to withstand an EMP. Hardening of
equipment used in communications and data networks is not an absolute guarantee that the
equipment will not be damaged in some manner by an EMP (Cohen, Modiano, Neumayer,
11. CYBER VULNERABILITY IN ELECTROMAGNETIC PULSE 11
Zussman, 2011, p1610). Since an EMP is an intense energy field it can instantaneously
overload, disrupt and/or disable numerous circuits over a large geographic area depending upon
the height of the detonation of the nuclear weapon. An EMP attack would have disastrous
effects on the U.S. telecommunication capabilities which are used by the emergency services
sector. Hardening emergency services systems is a solid countermeasure to an EMP; however,
there is not a countermeasure that can achieve one-hundred percent protection from an EMP.
Emergency services use personal type computer systems especially at the local governmental
level which often do not possess the financial resources to purchase computers which are
hardened against EMP. Computers in use in this sector that contain an 8088 processor based
system up to current 2016 computer processors are extremely vulnerable to fast transient
electromagnetic pulses and double exponential pulse shapes from EMP. The susceptibility to
EMP increases significantly with each computer generation (Camp, Garbe, 2006). The
countermeasure to this issue is for the federal government to either provide EMP hardened
equipment directly to state and local governments or to provide the financial resources to enable
the state and local governments to make purchases of EMP hardened equipment. The state and
local governments and the federal government would be well served by using federal
government contracts to purchase EMP hardened computer systems since the federal government
contract already contain the specifications for the EMP hardened computing systems. Doing so
would eliminate each state and local governments from using federal financial grants to purchase
a myriad of computing systems that may not be able to interconnect with emergency service
systems at the regional and federal levels and may not meet required standards for EMP
hardening for computing systems. The interconnectivity throughout the network for the
emergency services sector and ensuring all of the computing systems meet EMP hardening
12. CYBER VULNERABILITY IN ELECTROMAGNETIC PULSE 12
specifications takes priority over each state and local governments from acquiring their own
EMP hardened computing systems.
EMP Vulnerabilities in Energy Sector
Depending on the yield of the nuclear weapon and the height of the burst a nuclear EMP can
destroy large portions of the U.S. power infrastructure. An EMP attack would destroy the
electronics and digital circuitry in a large geographic area denying electrical power to homes,
businesses and military facilities that are not hardened against EMP. The United States is
dependent on electricity to power our health, financial, transportation, and business systems. If
the electrical power grid in the United States was ever lost over a large for an extended period of
time it would have catastrophic and lethal consequences for the population and the economy. It
would also degrade our military defenses. The United States’ digital dependence grows every
year and along with the dependence so does the vulnerability to EMP.
Computer simulations carried out in March 2010 at the Oak Ridge National Laboratories
demonstrated that an electromagnetic pulse from a nuclear device detonated at high attitude
could destroy or permanently damage major sections of the National power grid. According to
this Oak Ridge Study, the collapse of the power system could impact 130 million Americans,
and require four to ten years to fully recover and impose economic costs of $1 to $2 trillion
(Graham, 2012). The National electrical power grid has almost no backup capability in the event
of a power collapse from an EMP attack. Existing bulk power reliability standards don't address
EMP vulnerabilities. In addition, with most of the Nation's electrical power system under private
ownership who view an EMP attack as highly unlikely there has been little preparation for a
long-term electrical power collapse by private industry. Some progress has been made though
by the U.S. federal government in mitigating the EMP threat. The United States has conducted
13. CYBER VULNERABILITY IN ELECTROMAGNETIC PULSE 13
numerous exercises to test readiness against natural events such as hurricanes there has not been
a nationwide exercise to help prepare for severe consequences of a National power outage from
an EMP attack. The Grid Reliability and Infrastructure Defense (GRID) Act amends the Federal
Power Act to permit the Federal Energy Regulatory Commission (FERC) to issue new industry
standards to protect critical infrastructure from cyber and EMP attacks.
EMP Vulnerabilities in Financial Sector
The financial sector relies extensively upon computing systems and inter-networking to
conduct daily business. Banks are connected with the Society for Worldwide Interbank
Financial Telecommunications (SWIFT) network. SWIFT provides secure network for
transmitting messages between financial institutions; a set of syntax standards and market
practices for financial messages and a set of connection software and services which enable
financial institutions to transmit messages over the SWIFT network (Hammerli, 2012, p302).
The transmission protocol over the internet used between banks and clients to place orders and
obtain information is vulnerable to an EMP attack. The vulnerability is increasing daily as the
use and dependence on electronics and automated systems continues to grow exponentially. The
impact of EMP is asymmetric in relation to potential adversaries who are not as dependent upon
modern electronics as the United States is. The efficiency of the financial sector is generated
through the use of electronics and automated systems and that is also a potential vulnerability.
The current vulnerability of the financial sector to EMP attack both invites and rewards attack.
Correcting the vulnerabilities of the financial sector are feasible and within the national
means and resources to accomplish. It will require the combined effort of private and public
sectors of the United States. The appropriate response to the EMP threat is a balance of
14. CYBER VULNERABILITY IN ELECTROMAGNETIC PULSE 14
prevention, planning, training, maintaining situational awareness, protection and preparations for
recovery. This will reduce the incentives for the adversaries of the United States to conduct an
attack against America. Even though EMP was first considered during the Cold War as a
means of paralyzing U.S. retaliatory forces and eliminating America’s strategic deterrent of
responding in kind with an EMP attack. The risk of an EMP attack today is even greater since
several potential adversaries of the United States are seeking nuclear weapons, ballistic missiles,
and asymmetric ways to overcome the United States’ conventional superiority by using one or a
number of nuclear weapons to mount an EMP attack (Graham, 2008, p8). This would seriously
impact the financial system in the United States. Failure to take action to harden financial
communications and data networks to EMP attack will leave the critical national financial
infrastructure that are necessary for society to function at very high risk.
Recommendations
In summary, by implementing the following recommendations the effects of EMP can be
mitigated to ensure continued operation of critical infrastructure sectors: (1) harden equipment,
power grids, telecommunication and computing systems against EMP by using EMP shielding
technologies and underground facilities; (2) all levels of government from local to federal use
U.S. government federal EMP technical specifications and government contracts to acquire
EMP hardened telecommunication, power grid and computing systems and equipment; (3) local,
state and the federal government not use independent EMP specifications and contracts to
acquire EMP hardened telecommunications and computer systems and equipment to prevent
interconnectivity technical issues between telecommunications and computer systems at the
local, state and federal government levels and to avoid higher costs and duplication of effort; (4)
the U.S. federal government serve as the decision maker for all EMP technical specifications for
15. CYBER VULNERABILITY IN ELECTROMAGNETIC PULSE 15
telecommunication, power grid and computer systems contracts; (5) that the effectiveness of
EMP hardening have a higher priority than the cost; (6) the least cost technically acceptable
EMP hardening products not be selected for acquisition by the federal government or any other
level of government; (7) the EMP products with the greatest effectiveness to withstand an EMP
be selected during the federal acquisition process; (8) Department of Homeland Security (DHS)
to “make clear its authority and responsibility to respond to an EMP attack” by developing
contingency plans in cooperation with appropriate federal, state and local agencies, and industry
(Carafano, Spring, Weitz, 2011); (9) that DHS develop response protocols for an EMP attack and
regularly practice this response through exercises with relevant government agencies and
industry groups (Carafano et al. 2011); (10) DHS work with the Department of Energy and
industry groups to address vulnerabilities in the U.S. electrical infrastructure; (11) the cost of
critical infrastructure improvement to withstand an EMP attack be divided between the U.S.
federal government and industry.
Conclusion
In conclusion, this research provided a thorough review of cyber vulnerabilities in EMP
attacks. It addressed high altitude EMP (HEMP), low altitude nuclear bursts that produce Source
Region Electromagnetic Pulse (SREMP) and System Generated Electromagnetic Pulse
(SGEMP), cyber vulnerabilities to EMP in the emergency services, energy and financial sectors
and countermeasures. This project also summarized the key issues and provided
recommendations to resolve the issues. Some of the methods discussed include the Department
of Homeland Security working with private industry and the Department of Energy to
conducting nationwide exercises to assess preparedness for an EMP attack; EMP hardening of
telecommunication, power grid and computer systems to ensure their continued survivability
16. CYBER VULNERABILITY IN ELECTROMAGNETIC PULSE 16
during and after an EMP attack. The framework of a combined effort by the Department of
Homeland Security, Department of Defense, Department of Energy, state governments and
private industry going forward serves to ensure the critical infrastructure of the United States
continues to successfully function in the event of an EMP attack.
