      First Responders



I live in Minneapolis, so the collapse of the Interstate 35W bridge over 
the Mississippi River earlier this month hit close to home, and was 
covered in both my local and national news.

Much of the initial coverage consisted of human interest stories, 
centered on the victims of the disaster and the incredible bravery shown 
by first responders: the policemen, firefighters, EMTs, divers, National 
Guard soldiers, and even ordinary people, who all risked their lives to 
save others. (Just two weeks later, three rescue workers died in their 
almost-certainly-futile attempt to save six miners in Utah.)

Perhaps the most amazing aspect of these stories is that there's nothing 
particularly amazing about it. No matter what the disaster -- hurricane, 
earthquake, terrorist attack -- the nation's first responders get to the 
scene soon after.

Which is why it's such a crime when these people can't communicate with 
each other.

Historically, police departments, fire departments and EMTs have all had 
their own independent communications equipment, so when there's a 
disaster that involves them all, they can't communicate with each other. 
A 1996 government report said this about the *first* World Trade Center 
bombing in 1993: "Rescuing victims of the World Trade Center bombing, 
who were caught between floors, was hindered when police officers could 
not communicate with firefighters on the very next floor."

And we all know that police and firefighters had the same problem on 
9/11. You can read details in firefighter Dennis Smith's book and 9/11 
Commission testimony.  The "9/11 Commission Report" discusses this as 
well: Chapter 9 talks about the first responders' communications 
problems, and commission recommendations for improving 
emergency-response communications are included in Chapter 12 (pp. 396-397).

In some cities, this communication gap is beginning to close. Homeland 
Security money has flowed into communities around the country. And while 
some wasted it on measures like cameras, armed robots, and things having 
nothing to do with terrorism, others spent it on interoperable 
communications capabilities. Minnesota did that in 2004.

It worked. Hennepin County Sheriff Rich Stanek told the St. Paul 
Pioneer-Press that lives were saved by disaster planning that had been 
fine-tuned and improved with lessons learned from 9/11:

"'We have a unified command system now where everyone -- police, fire, 
the sheriff's office, doctors, coroners, local and state and federal 
officials -- operate under one voice,' said Stanek, who is in charge of 
water recovery efforts at the collapse site.

"'We all operate now under the 800 (megahertz radio frequency system), 
which was the biggest criticism after 9/11,' Stanek said, 'and to have 
50 to 60 different agencies able to speak to each other was just 
fantastic.'"

Others weren't so lucky. Louisiana's first responders had catastrophic 
communications problems in 2005, after Hurricane Katrina. According to 
National Defense Magazine:  "Police could not talk to firefighters and 
emergency medical teams. Helicopter and boat rescuers had to wave signs 
and follow one another to survivors. Sometimes, police and other first 
responders were out of touch with comrades a few blocks away. National 
Guard relay runners scurried about with scribbled messages as they did 
during the Civil War."

A congressional report on preparedness and response to Katrina said much 
the same thing.

In 2004, the U.S. Conference of Mayors issued a report on communications 
interoperability. In 25% of the 192 cities surveyed, the police couldn't 
communicate with the fire department. In 80% of cities, municipal 
authorities couldn't communicate with the FBI, FEMA, and other federal 
agencies.

The source of the problem is a basic economic one, called the 
"collective action problem." A collective action is one that needs the 
coordinated effort of several entities in order to succeed. The problem 
arises when each individual entity's needs diverge from the collective 
needs, and there is no mechanism to ensure that those individual needs 
are sacrificed in favor of the collective need.

Jerry Brito of George Mason University shows how this applies to 
first-responder communications. Each of the nation's 50,000 or so 
emergency-response organizations -- local police department, local fire 
department, etc. -- buys its own communications equipment. As you'd 
expect, they buy equipment as closely suited to their needs as they can. 
Ensuring interoperability with other organizations' equipment benefits 
the common good, but sacrificing their unique needs for that 
compatibility may not be in the best immediate interest of any of those 
organizations. There's no central directive to ensure interoperability, 
so there ends up being none.

This is an area where the federal government can step in and do good. 
Too much of the money spent on terrorism defense has been overly 
specific: effective only if the terrorists attack a particular target or 
use a particular tactic.  Money spent on emergency response is 
different: It's effective regardless of what the terrorists plan, and 
it's also effective in the wake of natural or infrastructure disasters.

No particular disaster, whether intentional or accidental, is common 
enough to justify spending a lot of money on preparedness for a specific 
emergency. But spending money on preparedness in general will pay off 
again and again.

In comments, people pointed out that that training and lack of desire to 
communicate are bigger problems than technical issues.  This is 
certainly true.  Just giving first responders interoperable radios won't 
automatically solve the problem; they need to want to talk to other 
groups as well.

      Basketball Referees and Single Points of Failure



Sports referees are supposed to be fair and impartial. They're not 
supposed to favor one team over another. And they're most certainly not 
supposed to have a financial interest in the outcome of a game.

Tim Donaghy, referee for the National Basketball Association, has been 
accused of both betting on basketball games and fixing games for the 
mob. He has confessed to far less -- gambling in general, and selling 
inside information on players, referees, and coaches to a big-time 
professional gambler named James "Sheep" Battista.  But the 
investigation continues, and the whole scandal is an enormous black eye 
for the sport.  Fans like to think that the game is fair and that the 
winning team really is the winning team.

The details of the story are fascinating and well worth reading. But 
what interests me more are its general lessons about risk and audit.

What sorts of systems -- IT, financial, NBA games, or whatever -- are 
most at risk of being manipulated? The ones where the smallest change 
can have the greatest impact, and the ones where trusted insiders can 
make that change.

Of all major sports, basketball is the most vulnerable to manipulation. 
There are only five players on the court per team, fewer than in other 
professional team sports; thus, a single player can have a much greater 
effect on a basketball game than he can in the other sports. Star 
players like Michael Jordan, Kobe Bryant and LeBron James can carry an 
entire team on their shoulders. Even baseball great Alex Rodriguez can't 
do that.

Because individual players matter so much, a single referee can affect a 
basketball game more than he can in any other sport. Referees call 
fouls. Contact occurs on nearly every play, any of which could be called 
as a foul. They're called "touch fouls," and they are mostly, but not 
always, ignored. The refs get to decide which ones to call.

Even more drastically, a ref can put a star player in foul trouble 
immediately -- and cause the coach to bench him longer throughout the 
game -- if he wants the other side to win. He can set the pace of the 
game, low-scoring or high-scoring, based on how he calls fouls. He can 
decide to invalidate a basket by calling an offensive foul on the play, 
or give a team the potential for some extra points by calling a 
defensive foul. There's no formal instant replay. There's no second 
opinion. A ref's word is law -- there are only three of them -- and a 
crooked ref has enormous power to control the game.

It's not just that basketball referees are single points of failure, 
it's that they're both trusted insiders and single points of 
catastrophic failure.

These sorts of vulnerabilities exist in many systems. Consider what a 
terrorist-sympathizing Transportation Security Administration screener 
could do to airport security. Or what a criminal CFO could embezzle. Or 
what a dishonest computer repair technician could do to your computer or 
network. The same goes for a corrupt judge, police officer, customs 
inspector, border-control officer, food-safety inspector, and so on.

The best way to catch corrupt trusted insiders is through audit. The 
particular components of a system that have the greatest influence on 
the performance of that system need to be monitored and audited, even if 
the probability of compromise is low. It's after the fact, but if the 
likelihood of detection is high and the penalties (fines, jail time, 
public disgrace) are severe, it's a pretty strong deterrent. Of course, 
the counterattack is to target the auditing system. Hackers routinely 
try to erase audit logs that contain evidence of their intrusions.

Even so, audit is the reason we want open source code reviews and 
verifiable paper trails in voting machines; otherwise, a single crooked 
programmer could single-handedly change an election. It's also why the 
Securities and Exchange Commission closely monitors trades by brokers: 
They are in an ideal position to get away with insider trading. The NBA 
claims it monitors referees for patterns that might indicate abuse; 
there's still no answer to why it didn't detect Donaghy.

Most companies focus the bulk of their IT-security monitoring on 
external threats, but they should be paying more attention to internal 
threats. While a company may inherently trust its employees, those 
trusted employees have far greater power to affect corporate systems and 
are often single points of failure. And trusted employees can also be 
compromised by external elements, as Tom Donaghy was by Battista and 
possibly the Mafia.

All systems have trusted insiders. All systems have catastrophic points 
of failure. The key is recognizing them, and building monitoring and 
audit systems to secure them.

This is my 50th essay for Wired.com.

      Interview with National Intelligence Director Mike McConnell



Mike McConnell, U.S. National Intelligence Director, gave an interesting 
interview to the El Paso Times.

I don't think he's ever been so candid before.  For example, he admitted 
that the nation's telcos assisted the NSA in their massive eavesdropping 
efforts.  We already knew this, of course, but the government has 
steadfastly maintained that either confirming or denying this would 
compromise national security.

There are, of course, moments of surreality.  He said that it takes 200 
hours to prepare a FISA warrant.  Ryan Single calculated that since 
there were 2,167 such warrants in 2006, there must be "218 government 
employees with top secret clearances sitting in rooms, writing only FISA 
warrants."  Seems unlikely.

But most notable is this bit:

"Q. So you're saying that the reporting and the debate in Congress means 
that some Americans are going to die?

"A. That's what I mean. Because we have made it so public. We used to do 
these things very differently, but for whatever reason, you know, it's a 
democratic process and sunshine's a good thing. We need to have the debate."

Ah, the politics of fear.  I don't care if it's the terrorists or the 
politicians, refuse to be terrorized.

Home Users: A Public Health Problem?



To the average home user, security is an intractable problem.  Microsoft 
has made great strides improving the security of their operating system 
"out of the box," but there are still a dizzying array of rules, 
options, and choices that users have to make.  How should they configure 
their anti-virus program?  What sort of backup regime should they 
employ?  What are the best settings for their wireless network? And so 
on and so on and so on.

How is it possible that we in the computer industry have created such a 
shoddy product?  How have we foisted on people a product that is so 
difficult to use securely, that requires so many add-on products?

It's even worse than that.  We have sold the average computer user a 
bill of goods.  In our race for an ever-increasing market, we have 
convinced every person that he needs a computer.  We have provided 
application after application -- IM, peer-to-peer file sharing, eBay, 
Facebook -- to make computers both useful and enjoyable to the home 
user.  At the same time, we've made them so hard to maintain that only a 
trained sysadmin can do it.

And then we wonder why home users have such problems with their buggy 
systems, why they can't seem to do even the simplest administrative 
tasks, and why their computers aren't secure.  They're not secure 
because home users don't know how to secure them.

At work, I have an entire IT department I can call on if I have a 
problem.  They filter my net connection so that I don't see spam, and 
most attacks are blocked before they even get to my computer. They tell 
me which updates to install on my system and when.  And they're 
available to help me recover if something untoward does happen to my 
system.  Home users have none of this support.  They're on their own.

This problem isn't simply going to go away as computers get smarter and 
users get savvier. The next generation of computers will be vulnerable 
to all sorts of different attacks, and the next generation of attack 
tools will fool users in all sorts of different ways.  The security arms 
race isn't going away any time soon, but it will be fought with ever 
more complex weapons.

This isn't simply an academic problem; it's a public health problem.  In 
the hyper-connected world of the Internet, everyone's security depends 
in part on everyone else's.  As long as there are insecure computers out 
there, hackers will use them to eavesdrop on network traffic, send spam, 
and attack other computers.  We are all more secure if all those home 
computers attached to the Internet via DSL or cable modems are protected 
against attack.  The only question is: what's the best way to get there?

I wonder about those who say "educate the users."  Have they tried? 
Have they ever met an actual user?  It's unrealistic to expect home 
users to be responsible for their own security.  They don't have the 
expertise, and they're not going to learn.  And it's not just user 
actions we need to worry about; these computers are insecure right out 
of the box.

The only possible way to solve this problem is to force the ISPs to 
become IT departments.  There's no reason why they can't provide home 
users with the same level of support my IT department provides me with. 
  There's no reason why they can't provide "clean pipe" service to the 
home.  Yes, it will cost home users more.  Yes, it will require changes 
in the law to make this mandatory.  But what's the alternative?

In 1991, Walter S. Mossberg debuted his "Personal Technology" column in 
The Wall Street Journal with the words: "Personal computers are just too 
hard to use, and it isn't your fault."  Sixteen years later, the 
statement is still true -- and doubly true when it comes to computer 
security.

If we want home users to be secure, we need to design computers and 
networks that are secure out of the box, without any work by the end 
users.  There simply isn't any other way.

This essay is the first half of a point/counterpoint with Marcus Ranum 
in the September issue of "Information Security."  You can read his

"Teen cracks AU$84 million porn filter in 30 minutes."  (AU$84 million 
is $69.5 million U.S.; that's real money.)  Remember that the issue 
isn't that one smart kid can circumvent the censorship software, it's 
that one smart kid -- maybe this one, maybe another one -- can write a 
piece of shareware that allows *everyone* to circumvent the censorship 
software.  It's the same with DRM; technical measures just aren't going 
to work.

"Cyber crime toolkits" hit the news:
http://news.bbc.co.uk/2/hi/technology/6976308.stm
In one sense, there's nothing new here.  There have been rootkits and 
virus construction kits available on the Internet for years.  The very 
definition of a "script kiddie" is someone who uses these tools without 
really understanding them.  What is new is the market: these new tools 
aren't for wannabe hackers, they're for criminals.  And with the new 
market comes a for-profit business model.

I had been thinking about writing about the massive 
distributed-denial-of-service attack against the Estonian government 
last April.  It's been called the first cyberwar, although it is unclear 
that the Russian government was behind the attacks.  And while I've 
written about cyberwar in general, I haven't really addressed the 
Estonian attacks.  Now I don't have to.  Kevin Poulsen has written an 
excellent article on both the reality and the hype surrounding the 
attacks on Estonia's networks, commenting on a story in the magazine

The APEC conference was a big deal in Australia, and the security was 
serious.  They blocked off a major part of Sydney, implemented special 
APEC laws allowing extra search powers for the police, and even gave 
everyone in Sydney the day off -- just to keep people away.  But the 
Chasers, a TV comedy team, succeeded in driving a fake motorcade with 
Canadian flags right through all the security barriers and weren't 
stopped until right outside President Bush's hotel. Inside their 
motorcade was someone dressed up as Osama Bin Laden.

eavesdrop on the other team, but selectively jam the signal when it 
would be most critical. The rules said that if one team's radio link

consideration if you know it's coming.

      Vague Threat Prompts Overreaction



It reads like a hoax:  "The Police Department set up checkpoints 
yesterday in Lower Manhattan and increased security after learning of a 
vague threat of a radiological attack here."

And:  "The police learned about the threat through an item on the Web 
site debka.com -- a site that Mr. Browne said was believed to have 
Israeli intelligence and military sources -- that said that Qaeda 
operatives were planning to detonate a truck filled with radiological 
material in New York, Los Angeles or Miami. Officials say the Web site 
carries reports that are often wrong, but occasionally right."

Occasionally right?  Which U.S. terrorist attack did it predict?

Come on, people: refuse to be terrorized.

      Stupidest Terrorist Overreaction?



Is this the stupidest terrorist reaction yet?  "Two people who sprinkled 
flour in a parking lot to mark a trail for their offbeat running club 
inadvertently caused a bioterrorism scare and now face a felony charge."

The competition is fierce, but I think we have a winner.

What bothers me most about the news coverage is that there isn't even a 
suggestion that the authorities' response might have been out of line.

"Mayoral spokeswoman Jessica Mayorga said the city plans to seek 
restitution from the Salchows, who are due in court Sept. 14.

"'You see powder connected by arrows and chalk, you never know,' she 
said. 'It could be a terrorist, it could be something more serious. 
We're thankful it wasn't, but there were a lot of resources that went 
into figuring that out.'"

Translation: We screwed up, and we want someone to pay for our mistake.

      Wholesale Automobile Surveillance Comes to New York City



New York is installing an automatic toll-collection system for cars in 
the busiest parts of the city.  It's called congestion pricing, and it 
promises to reduce both traffic and pollution.

The problem is that it keeps an audit log of which cars are driving 
where.  London's congestion pricing system is already being used for 
counterterrorism purposes -- and now for regular crime as well.  The 
E-ZPass automatic toll collection system, used in New York and other 
places, has been used in both criminal and civil trials: in one case to 
prove infidelity in divorce court.

There are good reasons for having this system, but I am worried about 
another wholesale surveillance tool.

      U.S. Government Threatens Retaliation Against States who Reject
        REAL ID



REAL ID is the U.S. government plan to impose uniform regulations on 
state driver's licenses.  It's a national ID card, in all but cosmetic 
form.

Most states hate it: 17 have passed legislation rejecting REAL ID, and 
many others have such legislation somewhere in process.  Now it looks 
like the federal government is upping the ante, and threatening 
retaliation against those states that don't implement REAL ID:

"The cards would be mandatory for all 'federal purposes,' which include 
boarding an airplane or walking into a federal building, nuclear 
facility or national park, Homeland Security Secretary Michael Chertoff 
told the National Conference of State Legislatures last week. Citizens 
in states that don't comply with the new rules will have to use 
passports for federal purposes."

This sounds tough, but it's a lot of bluster.  The states that have 
passed anti-REAL-ID legislation lean both Republican and Democrat.  The 
federal government just can't say that citizens of -- for example -- 
Georgia (which passed a bill in May authorizing the governor to delay 
implementation of REAL ID) can't walk into a federal courthouse without 
a passport.  Or can't board an airplane without a passport -- imagine 
the lobbying by Delta Airlines here.  They just can't.

      Computer Forensics Case Study



This is a report on the presentation of computer forensic evidence in a 
UK trial.

There are three things that concern me here:

1. The computer was operated by a police officer prior to forensic 
examination.

2. The forensic examiner gave an opinion on what files construed 
"radical Islamic politics."

3. The presence of documents "in the "Windows Options" folders was 
construed as evidence that that someone wanted to hide those documents.

In general, computer forensics is rather ad hoc.  Traditional rules of 
evidence are broken all the time.  But this seems like a pretty 
egregious example.

      Getting Free Food at a Fast-Food Drive-In



It's easy.  Find a fast-food restaurant with two drive-through windows: 
one where you order and pay, and the other where you receive your food. 
  This won't work at the more-common U.S. configuration: a microphone 
where you order, and a single window where you both pay and receive your 
food.  The video demonstrates the attack at a McDonald's in -- I assume 
-- France.

Wait until there is someone behind you and someone in front of you. 
Don't order anything at the first window.  Tell the clerk that you 
forgot your money and didn't order anything.  Then drive to the second 
window, and take the food that the person behind you ordered.

It's a clever exploit.  Basically, it's a synchronization attack.  By 
exploiting the limited information flow between the two windows, you can 
insert yourself into the pay-receive queue.

It's relatively easy to fix.  The restaurant could give the customer a 
numbered token upon ordering and paying, which he would redeem at the 
next window for his food.  Or the second window could demand to see the 
receipt.  Or the two windows could talk to each other more, maybe by 
putting information about the car and driver into the computer.  But, of 
course, these security solutions reduce the system's optimization.

So if not a lot of people do this, the vulnerability will remain open.
