Under today’s technological conditions, the “all
conquering stratagems” of Sun Tzu more than two
millennia ago – “vanquishing the enemy without
fighting” and subduing the enemy by “soft strike” or
“soft destruction” – could finally be truly realized.
Quote from the Chinese Army
Newspaper, Jiefangjun Bao, from a
summary of speeches delivered in
May 1996.
"A Glimpse of Cyberwarfare" U.S. News & World Report (03/13/00) Vol. 128, No. 10, P. 32; (Strobel,
Warren P.): Various governments around the world are using the Internet to suppress dissent,
harass their enemies, obtain trade secrets, and even prepare for war. Although computer security
experts admit that some of the worst-case scenarios have yet to happen, such as rogue
governments using computers to wreak havoc on financial systems, they warn that more than 12
countries, including China, Iraq, Iran, and Russia already possess fairly sophisticated informationwarfare know-how. For example, China is currently debating whether to devote a fourth branch of
its military solely to information warfare, and the Pentagon will consolidate its offensive
cyberwarfare programs at the U.S. Space Command in Colorado later this year. Experts say
cyberwars pose great ethical and legal dilemmas, as there is no clear separation point between
military sites and those devoted to civilian infrastructure, as in physical wars. Military analysts
admit that the U.S. may be the biggest loser if cyberwarfare becomes an accepted form of battle,
as it is the country most tightly strung together by computer networks. Because of the widespread
damage that cyberwarfare could lead to, some countries such as Russia have proposed treaties on
the matter, similar to arms control agreements. However, experts say verifying such an agreement
would be nearly impossible given the nature of computer networks. Electronic spying could also
become as problematic as cyberwarfare, as many government agencies are rich with detailed,
classified information that is extremely valuable to an enemy. Security professionals say not only
can information be taken from a computer, but an unfriendly entity could also place bogus
information into a computer, causing military leaders to make decisions about troop locations or
battlefield conditions based on fictional data. Most military analysts contend that the computer has
made the world an even more dangerous place. *

NSA monitors fifty-three thousand communications signals in
the U.S. every day. Then, acres and acres of supercomputers
with eavesdropping and code breaking capabilities
automatically look for meaningful information amongst the
hurricane of data that enters Fort Meade, Maryland. The NSA
can listen for and detect key words in phone conversations.
NSA computers will trigger alarms and in seconds a platoon of
experts will be dissecting the recorded conversation.
ECHELON is a code word for an automated global interception
system operated by the intelligence agencies of the US, UK,
Canada, Australia, and New Zealand, and lead by the NSA.
Some sources claim ECHELON sifts through 90 percent of the
Internet’s traffic.

Computer Security Institute (CSI) - based on responses
from 643 computer security practitioners in U.S. corporations,
government agencies, financial institutions, medical
institutions and universities. Ninety percent of survey
respondents detected cyber attacks, 273 organizations report
$265,589,940 in financial losses, including denial of service
attacks, Web-site vandalism, financial fraud, sabotage of data
or networks, and theft of proprietary information.
FBI - 95 percent of all attacks by hackers go unreported
Kevin Poulson (1992)– convicted for stealing and trafficking
telephone access codes for the Soviet Union and wiretapping
conversations of Pacific Bell officials who were investigating
him.
Sunday Times in Britain (1999) - hackers attempting to
blackmail several bank’s security , they claim they can disrupt
bank operations and have lists of private clientele information
they will publish

A survey by Global Integrity, a computer security company
showed that more than twenty-five of the world’s largest
banks were hacked into in 1999
British authorities (2000), with the assistance of the FBI,
arrested two eighteen-year-old British citizens who had
stolen over twenty-six thousand credit card accounts using
the Internet
(2000) A leak of early design information cost a mediumsized producer of consumer electronic goods $35 million in
anticipated sales when a competitor obtained the
information and used it to introduce its own version of the
product much sooner
Identity theft – the forging of someone’s identity for the
purpose of fraud. 2003: 10 million victims.
Network Intrusion Techniques


Van Eck Devices – a computer is actually a miniature
transmitting broadcasting all of its information into the air. A
Van Eck receiving device can “read” a screen up to around one
half of a city block away.
High Energy Radio Frequency (HERF) Gun – shoots a high
power radio signal at an electronic target and puts it out of
commission. Designed to overload electronic circuitry.
ElectroMagnetic Pulse Transformer (EMP/T) Bomb – so strong
any computer in its path will likely be rendered useless forever.
Electronic circuitry will be melted beyond repair and all
magnetically stored data will be completely erased.
Hacking – illegally intruding in to a computer network. A
hacker is someone interested in operating systems, software,
security, and the Internet generally.

Data-Driven Attacks – an attack that relies upon hidden or
encapsulated data, which may be designed to flow through a
firewall undetected.
Social Engineering – tricking an unwary system personnel into
revealing passwords or other information about their network.
Spoofing – any procedure that involves impersonating another
user or host to gain unauthorized access to the target.
Hijacking – terminal hijacking, where an attacker seizes
control of another user’s session.
Back Door – a hidden program, left behind by an intruder or a
disgruntled employee that allows them future access to a
victim host, a.k.a., trap door.

DoS – Denial of Service – results when a user maliciously renders an
Internet information server inoperable, thereby denying computer
service to legitimate users.
Flood, Floods, Flooder – tool or tools that overflow the connection
queue of a TCP/IP enabled system, thereby causing denial of service.
Logic Bomb – any program or code—generally malicious—that causes
a system to lock up or fail.
Cyberslacking – misuse of company resources.
Cookie – a small file that contains information about you and your
Web activities, which a Web site places on your computer.
Anonymous Web browsing (AWB) – hides your identity from the
Web sites you visit.
About 2,000 government agencies have databases with information
on people. Whenever you are in contact with government agency,
you leave behind information about yourself.

Computer sabotage costs about $10 billion per year. In
general, employee misconduct is more costly than assaults
from outside.
Sniffer – program that surreptitiously captures datagrams
across a network. Can be used to steal usernames and
passwords.
Time Bomb – any program that waits for a specified amount of
time or event to disable a machine or otherwise cause that
machine to fail.
Traffic Analysis – the study of patterns in communication
rather than the content of the communication. Can be very
revealing, primarily in determining relationships between
individuals and hosts.
Trojan (Trojan Horse) – an application or code that,
unbeknownst to the user, performs surreptitious and
unauthorized tasks. Those task can compromise system
security.
Identity Theft by Age of Victims
Cybersecurity Counter Measures
 Make cybersecurity a company wide philosophy
 Purchase Internet insurance
 Do not allow anyone access to your system who has
not been invited or who has not been verified using
several different technologies and photograph all
individuals who ask for access to your system
 Guards should know their job is secure, even if they
prevent a high level official from the firm from
entering an installation without the proper
identification and authorization
 Sensitive information should be destroyed before
being thrown out
Cybersecurity Counter Measures – Con’t
 If an individual does not use their account within a
specific period of time, they should be automatically
logged off
 Always change all default settings dealing with
passwords and usernames when setting up a
system
 Do not use obvious passwords
 Change passwords relatively often
 Use 128-bit encrypted browsers
 Make sure your email software is up-to-date
 Encrypt all files sent through email
Cybersecurity Counter Measures – Con’t
 Make sure your web browser is up-to-date
 Use the best security hardware and software that is
available and read and follow the recommendations
that are included with the software to prevent
unauthorized access to your system
 Thoroughly train and certify you security personnel
Summary
 It would not be surprising if a catastrophic
terrorist event occurred in the near future
