Richard Clarke
has more bad news for IT execs.
During his tenure as White House cybersecurity czar, Clarke
was frequently criticized for his "sky-is-falling" attitude.
Indeed, Clarke claims that the Sobig attack brought down a chunk
of sky and that his warnings should have been taken more seriously.
If current trends
continue, Clarke told attendees at Gartner's Symposium/ITxpo
2003 here this week, the cybersecurity situation isn't just
going to get worse. It's going to get exponentially worse.
Noting that the conference's
location (Disney World) might be appropriate because "only in
fantasy land can everything you have be secure," Clarke identified
five trends that don't bode well for those trying to deal with
cyber attacks.
The first of these
trends has to do with the number of software vulnerabilities.
After assimilating data from sources such as Bugtraq, the SANS
Institute, and the vendors themselves, Clarke said the number
of announced vulnerabilities has doubled every year for the
last three years. "At this point," said Clarke, "we're now seeing
as many as 60 new vulnerabilities per week."
A second trend that
closely tracks the first, according to Clarke, is the number
of patches for those vulnerabilities, which also has doubled
every year for the past three years. Patch management is a road
full of potholes.
"No sooner do the
patches get applied, then they have to apply another one," Clarke
said. "CIOs want these patches applied but have no idea what
the effect of the patch will be on their systems, so they're
reluctant to put them on quickly. Also, they want to wait until
they have a bunch of patches first, and then test them before
deploying them. But, during the wait period, they're vulnerable
and some have been successfully attacked in that window."
The third trend Clarke
is watching is what he called the "time to exploit." This is
a measurement of the elapsed time between the moment a vulnerability
is announced and when the corresponding exploit makes its first
appearance on IRC or some other chat room. Said Clarke, "It's
gone from months to weeks to days, and now it's about six hours.
Clarke's fourth trend
is the rate of propagation of the attacks. "In July 2001, Code
Red was a big deal" said Clarke. "I was the White House cybersecurity
guy at that time and we knew something was going on, but we
didn't know what. We knew it was a big threat, though. So, we
reached out to all the security-related agencies--the NSA, CIA,
FBI, even the private sector--and by 4pm on that day, we had
broken the code and knew what was going to happen: At 8pm Eastern
Time, 300,000 machines were going to launch a distributed denial
of service attack (DDoS) on the White House's domain."
To mitigate the attack's
impact, he asked the major Internet backbone providers to black-hole
all traffic destined for whitehouse.gov. "So, when the tsunami
hit the edge routers, it just died," said Clarke.
Comparing Code Red
to the Slammer worm, which originated from South Korea, Clarke
said, "We saw the same phenomenon earlier this year. It involved
300,000 computers from five continents, but instead of taking
a day, it all happened in 14 minutes. So, when you combine the
six hours of vulnerability-to-exploit with the 14 minutes it
takes to complete an attack, not only are "they" evolving, but
reaction time is shrinking. Bottom line: If you don't have defenses
already set up to deal with problem, you will be a victim."
The fifth trend to
watch is the rising cost of cleanup. Precise cost estimates
are difficult to come by, said Clarke, because too little is
known about the reporting methodologies used to collect the
data. Still, Clarke said, "The numbers may not be accurate,
but the trend lines are. According to the data we have, the
worldwide cost in 2002 was $48 billion. This past August [when
Sobig.f struck], the cost for one month alone was $35 billion.
Depending on whom you talk to, the total projected worldwide
cost for 2003 is $119 billion to $145 billion. Compared to the
$35 billion from the year before, that's a huge upward curve."
Another trend that
Clarke discussed had to do with identity theft. According to
Clarke, recent data suggests that approximately 27 million Americans
were victimized by some form of identity theft in the past five
years. "Of those 27 million, 9.9 million of them--more than
a third--came in the last year," said Clarke. "The FTC estimates
that each incidence of an identity theft costs the company involved
an average of $10,000. With almost 10 million happening in one
year, you do the math."
Clarke used specific
events to demonstrate what he called a "sea-state change" in
the cybersecurity situation. "For the last three years, I've
been saying that there will be attacks on critical infrastructure
such as transportation, banking, and power," Clarke said. "Let's
look at what happened this year."
Clarke recounted how
cyber attacks knocked out The Bank of America's ATM network,
stopped or slowed CSX Railroad's trains, cancelled some of Continental
Airline's flights, and forced offline a nuclear power plant
in Ohio.
Regarding the Ohio
blackout, Clarke noted the irony in a White House report refuting
his assertion on ABC News that it could have been the result
of a cyber attack. "I had no idea what it was," said Clarke.
But it might have been a cyber attack. The White House was saying
it wasn't a cyber attack but, then again, couldn't say what
it was. Then, the White House went on to ask former FBI National
Infrastructure Protection Center director Ron Dick to investigate
the cyber attack angle." The NIPC [link: www.nipc.gov ], which
is now a part of the U.S. Department of Homeland Security, focuses
almost exclusively on cybersecurity issues. "Make of that what
you want," said Clarke.
According to Clarke,
the U.S. power grid hasn't been the only grid to experience
trouble recently. "The recent collapse of the Italian and British
power grids has so far gone unexplained," said Clarke. "Oslo
recently reported that cyber attackers attempted to bring down
Norway's power grid, and Israel's intelligence agency Shin Bet
recently reported that Israel's power grid has been the target
of several cyber attacks. All of our infrastructure, including
power and the Internet, are vulnerable."
Perhaps the worst
news contained in Clarke's presentation is that nobody has been
caught. "Look at all of the cyber attacks," said Clarke, "The
FBI only has one high school kid who had neon signs in his windows
saying 'I did it' and all he did was capture an existing virus
(MSBlast) and modify it. The originator was never caught."
Clarke cautioned Gartner
Symposium/ITxpo attendees against complacency. "When you hear
everyone talking about IT security and you see it in the publications
and from vendors, it becomes noise and you tend to turn it off.
This is a mistake. What does this say about the future? It's
not a pretty picture."
