In March of 1831, a man named Edward Smith robbed the first bank in
the United States. Using a duplicate set of keys, Smith walked into
City Bank on Wall Street on a Sunday, and walked out with $245,000.
He was arrested later in the week and spent four years in jail for his
heist.
In May 2001, the FBI arrested two young Russian men for robbing the
Nara Bank of Los Angeles and the Central National Bank of Waco, Tex.,
among other businesses. Using more than 50,000 credit card numbers they
scammed from hacking into financial service company computers from an
operation in Chelyabinsk, the two Russians not only stole money from
the banks but more than 40 other businesses across ten states, according
to investigators. The FBI estimated the pair accounted for more than
$25 million in financial losses to the banks, the other businesses,
and American citizens. The two Russians are now serving time in federal
prisons.
From Jesse James to Butch Cassidy and the Sundance Kid to John Dillinger,
the romantic notion of the bank robber has long been a part of American
lore. But the case of the young Russians underscores the fact that modern-day
thieves are more likely to be sitting in front of a computer, halfway
around the world at that. The keys that rob a bank now lie on the keyboard
of a hacker working to break down the computer code protecting the operating
systems of businesses and banks.
“It used to be that an individual involved in robbing a bank or some
other business could do a limited amount of damage,” says Ralph Merkle,
professor of computing at Georgia Tech, and director of the school’s
Information Security Center. “But now, with a replicating computer program,
one person could rob all the banks on the planet. A small handful of
people can cause huge economic damage. It’s not that there are more
evil people in the world, it’s just the use of the computer has had
a leveraging effect on crime.”
Information security—whether providing government agencies with protection
against terrorism or private corporations the tools to prevent costly
attacks—has become of paramount importance in this country and abroad.
Engineering schools are responding to the need by providing research
and programs to combat the threat of computer crime, which started as
prankish hacking and has now emerged as a huge problem for law enforcement
agencies.
The National Security Agency (NSA) has designated 50 colleges and universities—including
Georgia Tech—as Centers of Academic Excellence in Information Assurance.
The programs these schools are providing are diverse. Some focus on
computer-aided forensics, others on terrorist hacking into infrastructure
like electrical grids; and still others concentrate on preventing cyber
thievery in private industry. The programs are interdisciplinary, utilizing
faculty from engineering and computer science in conjunction with experts
in business, law, ethics, and political science.
Quantifying the damage from computer crime is difficult. Identity theft,
credit card fraud, damage from viruses and worms, child pornography,
stolen laptops, hacking into the Department of Defense—all these offenses
can be lumped into the computer crime category. That some private companies
are reluctant to report some computer crime, fearing the exposed vulnerabilities
might encourage more attacks and hurt stock prices, complicates matters.
According to a survey conducted by California-based Computer Security
Research Lab in conjunction with the FBI, the number of intrusions into
networks has increased every year for the past five. The average financial
loss to companies reporting an intrusion was $2.7 million. The Tower
Group Inc., a computer industry research firm, estimates identity theft
costs the banking industry $1 billion a year. Incredibly, the research
firm said that 10,000 identity theft victims had had home loans taken
out in their names to the tune of $300 million.
Some put the tag at worldwide losses from computer crime at $30 billion
every year. Others say it is double that. Government and private business
have gotten the message and are starting to invest in the security of
their systems. Infonetics Research estimates that spending on security
in the U.S. private sector will grow from $4.5 billion in 2003 to $8
billion in 2007.
“We are just looking at a totally different kind of criminal,” says
Sushil Jajodia, professor of information technology and engineering
and director of the Center for Secure Information Systems at George
Mason University in Virginia. “We have criminals trying to steal money,
we have insiders corrupting software systems, but we also have nation-states
and terrorists looking to bring our networks down, from telephone systems
to electric grids to airplane traffic.”
Jajodia estimates that 80 percent of the 800 students studying information
technology at George Mason are concentrating on information assurance.
If software design was the hot major in the nineties, information assurance
might be the major of choice in the new millennium. After creating the
Internet world in the nineties, U.S. engineers are now increasingly
working toward making that world safer.
The problem is that information assurance is a relatively young field.
One of the early programs was the CERT Center at the Software Engineering
Institute at Carnegie Mellon University. CERT was established in 1988
when the first Internet worm became a security problem. CERT is now
a clearinghouse and research institution that monitors incidences and
offers instant help in fighting viruses and worms. In 2000, 21,756 such
incidences were reported to CERT. That number had grown to 137,529 by
2003.
Internal Flaws
One of the problems facing both private industry and government are
the financial pressures to bring software products to market quickly,
and the lack of security features in those products. “We continue to
see the same types of vulnerabilities in newer versions of [software]
products that we saw in earlier versions,” CERT’s director, Richard
D. Pethia, testified last year before the House Subcommittee on Cyber
Security, Science and Research, and Development. “Technology evolves
so rapidly that vendors concentrate on time to market, often minimizing
that time by placing a low priority on security features. Until their
customers demand products that are more secure, the situation is unlikely
to change.”
Eugene H. Spafford, professor of computer science and director of the
Center for Education and Research in Information Assurance and Security
at Purdue University, says part of the problem is the one-size-fits-all
approach to software design and the reliance on the software patch system
to clear up security problems. Spafford says that 4,000 software flaws
were identified, and corresponding patches implemented, by companies
last year.
Spafford likes to use construction analogies to illustrate his point:
“It would be as if you had carpenters and roofers and electricians building
a structure, and you gave everyone the same Swiss Army knife. They might
be able to do their job, but they can’t do it very well. In the software
industry, we need to customize the tools for the task at hand. We need
good design methods for designing software for specific needs. That
will help to provide security.”
A program for weapons systems at the Pentagon and someone using the
Internet to cruise for recipes uses the same basic platform. The software
is written to the lowest common denominator, which makes it easier for
almost anyone with a cursory bit of knowledge to compromise these systems.”
James A. Davis, professor of electrical and computer engineering at
Iowa State University and a faculty member of the school’s Information
Assurance Center, says the problem facing educators is twofold. University
information security professors must look at long-term changes in both
hardware and software—the “next big thing,” so to speak—and at the same
time advise private corporations and government on how to secure their
systems on a day-to-day basis. And after years of sometimes sluggish
responses from government and private industry, the recent spate of
attacks is making security a pressing issue.
More and more schools are responding by offering majors and doctoral
programs in information assurance, and commercial research possibilities
for developing products in the marketplace are beginning to become available.
“We are working hard with some companies to commercialize some of the
applied solutions we have,” says Jajodia. “That is one of our goals.
We have to do critical research, but the research has to get into the
marketplace so it can be effective.”
Uncle Sam Takes Notice
The U.S. government is seeing the threat of computer crime as a very
real one. The Department of Homeland Security is now providing a National
Cyber Alert System that will issue warnings about worms, viruses, and
Internet scams, and provide information on improving security warnings.
The federal government is also funding a program called Cyber Corps,
which spends $30 million at 13 of the NSA approved schools for 200 scholarships
for students studying information security. In return, the students
are obliged to work in a government agency for two years after graduation.
The Cyber Corps program has had some problems. The Federal Office of
Personnel Management has had trouble placing some of the graduates,
because some government agencies have been reluctant to hire what they
consider inexperienced infosec administrators and place them in senior
management positions. Despite the problems, most information security
professors say the program is vital. “The government had decided they
want to infuse some of these vital national agencies with young talent,”
says Ray Vaughn, professor of computer science and engineering at Mississippi
State University, and director of the school’s Center for Computer Security
Research. “The current terrorist threat has increased the visibility
of this program, and getting graduates who really know about security
is vital to our national interests.”
One of the most discussed topics in the academic community regarding
computer security is whether there is a need to teach students the ways
of the criminal. In other words, do students need to know how to break
down firewalls and to create Internet worms to know how to protect against
them? “This is one of the hotly debated topics in the security community,”
says Iowa State’s Davis. “We have a class in information warfare. We
set up a firewall and we tell students to use tools to get through the
firewall. Then we turn it around and tell students to find solutions
to protecting that firewall.”
Purdue’s Spafford takes a different approach: “I wouldn’t teach students
how to pour sugar into gas tanks and how to break into cars if I was
teaching students how to create systems that protect against auto theft
or vandalism,” he says. “We don’t teach hacking or how to create viruses.
We teach how to make systems more secure and to do research that aids
that goal.”
Regardless of the debate on how to teach information security, everyone
involved—government, private industry, and academia—realizes that the
key to getting a handle on computer security is the research being done
at colleges and universities around the country, and getting more students
into the pipeline to serve the needs of all the constituencies involved.
“Five years ago, no one really cared,” says Georgia Tech’s Ralph Merkle.
“But companies are getting burned and they’re now realizing they have
to spend money for secure software. Our graduates are going into a variety
of areas: government, law enforcement, and private industry. The greater
the expertise we can provide, the better knowledge we can put into the
workforce, the more we can lower the risk.”
