N-DEx National Intelligence System

An article from The Washington Post:

Federal authorities hope N-DEx will become what one called a “one-stop shop” enabling federal law enforcement, counterterrorism and intelligence analysts to automatically examine the enormous caches of local and state records for the first time.

[…]

The expanding police systems illustrate the prominent roles that private companies play in homeland security and counterterrorism efforts. They also underscore how the use of new data—and data surveillance—technology to fight crime and terrorism is evolving faster than the public’s understanding or the laws intended to check government power and protect civil liberties, authorities said.

Three decades ago, Congress imposed limits on domestic intelligence activity after revelations that the FBI, Army, local police and others had misused their authority for years to build troves of personal dossiers and monitor political activists and other law-abiding Americans.

Since those reforms, police and federal authorities have observed a wall between law enforcement information-gathering, relating to crimes and prosecutions, and more open-ended intelligence that relates to national security and counterterrorism. That wall is fast eroding following the passage of laws expanding surveillance authorities, the push for information-sharing networks, and the expectation that local and state police will play larger roles as national security sentinels.

Law enforcement and federal security authorities said these developments, along with a new willingness by police to share information, hold out the promise of fulfilling post-Sept. 11, 2001, mandates to connect the dots and root out signs of threats before attacks can occur.

Speeding Tickets and Agenda

If you ever need an example to demonstrate that security is a function of agenda, use this story about speed cameras. Cities that have installed speed cameras are discovering motorists are driving slower, which is decreasing revenues from fines. So they’re turning the cameras off.

Perhaps a better solution would be to raise the fines to the remaining speeders to make up for the lost revenue?

EDITED TO ADD (3/31): Too many people thought that above comment was serious. It’s not. The whole incident illustrates why fines should never be considered part of a revenue stream: it gives the police a whole new agenda.

Web Entrapment

Frightening sting operation by the FBI. They posted links to supposed child porn videos on boards frequented by those types, and obtained search warrants based on access attempts.

This seems like incredibly flimsy evidence. Someone could post the link as an embedded image, or send out e-mail with the link embedded, and completely mess with the FBI’s data—and the poor innocents’ lives. Such are the problems when the mere clicking on a link is justification for a warrant.

Detecting Gunshots

Minneapolis—the city I live in—has an acoustic system that automatically detects and locates gunshots. It’s been in place for a year and a half.

The main system being considered by Minneapolis is called ShotSpotter. It could cost up to $350,000, and some community groups are hoping to pitch in.

That seems like a bargain to me.

Recently, I was asked about this system on Winnipeg radio. Actually, I kind of like it. I like it because it’s finely tuned to one particular problem: detecting gunfire. It doesn’t record everything. It doesn’t invade privacy. If there’s no gunfire, it’s silent. But if there is a gunshot, it figures out the location of the noise and automatically tells police.

From a privacy and liberties perspective, it’s a good system. Now all that has to be demonstrated is that it’s cost effective.

Privacy and Power

When I write and speak about privacy, I am regularly confronted with the mutual disclosure argument. Explained in books like David Brin’s The Transparent Society, the argument goes something like this: In a world of ubiquitous surveillance, you’ll know all about me, but I will also know all about you. The government will be watching us, but we’ll also be watching the government. This is different than before, but it’s not automatically worse. And because I know your secrets, you can’t use my secrets as a weapon against me.

This might not be everybody’s idea of utopia—and it certainly doesn’t address the inherent value of privacy—but this theory has a glossy appeal, and could easily be mistaken for a way out of the problem of technology’s continuing erosion of privacy. Except it doesn’t work, because it ignores the crucial dissimilarity of power.

You cannot evaluate the value of privacy and disclosure unless you account for the relative power levels of the discloser and the disclosee.

If I disclose information to you, your power with respect to me increases. One way to address this power imbalance is for you to similarly disclose information to me. We both have less privacy, but the balance of power is maintained. But this mechanism fails utterly if you and I have different power levels to begin with.

An example will make this clearer. You’re stopped by a police officer, who demands to see identification. Divulging your identity will give the officer enormous power over you: He or she can search police databases using the information on your ID; he or she can create a police record attached to your name; he or she can put you on this or that secret terrorist watch list. Asking to see the officer’s ID in return gives you no comparable power over him or her. The power imbalance is too great, and mutual disclosure does not make it OK.

You can think of your existing power as the exponent in an equation that determines the value, to you, of more information. The more power you have, the more additional power you derive from the new data.

Another example: When your doctor says “take off your clothes,” it makes no sense for you to say, “You first, doc.” The two of you are not engaging in an interaction of equals.

This is the principle that should guide decision-makers when they consider installing surveillance cameras or launching data-mining programs. It’s not enough to open the efforts to public scrutiny. All aspects of government work best when the relative power between the governors and the governed remains as small as possible—when liberty is high and control is low. Forced openness in government reduces the relative power differential between the two, and is generally good. Forced openness in laypeople increases the relative power, and is generally bad.

Seventeen-year-old Erik Crespo was arrested in 2005 in connection with a shooting in a New York City elevator. There’s no question that he committed the shooting; it was captured on surveillance-camera videotape. But he claimed that while being interrogated, Detective Christopher Perino tried to talk him out of getting a lawyer, and told him that he had to sign a confession before he could see a judge.

Perino denied, under oath, that he ever questioned Crespo. But Crespo had received an MP3 player as a Christmas gift, and surreptitiously recorded the questioning. The defense brought a transcript and CD into evidence. Shortly thereafter, the prosecution offered Crespo a better deal than originally proffered (seven years rather than 15). Crespo took the deal, and Perino was separately indicted on charges of perjury.

Without that recording, it was the detective’s word against Crespo’s. And who would believe a murder suspect over a New York City detective? That power imbalance was reduced only because Crespo was smart enough to press the “record” button on his MP3 player. Why aren’t all interrogations recorded? Why don’t defendants have the right to those recordings, just as they have the right to an attorney? Police routinely record traffic stops from their squad cars for their own protection; that video record shouldn’t stop once the suspect is no longer a threat.

Cameras make sense when trained on police, and in offices where lawmakers meet with lobbyists, and wherever government officials wield power over the people. Open-government laws, giving the public access to government records and meetings of governmental bodies, also make sense. These all foster liberty.

Ubiquitous surveillance programs that affect everyone without probable cause or warrant, like the National Security Agency’s warrantless eavesdropping programs or various proposals to monitor everything on the internet, foster control. And no one is safer in a political system of control.

Creating and Entrapping Terrorists

When I wrote this essay—“Portrait of the Modern Terrorist as an Idiot”—I thought a lot about the government inventing terrorist plotters and entrapping them, to make the world seem scarier. Since then, it’s been on my list of topics to write about someday.

Rolling Stone has this excellent article on the topic, about the Joint Terrorism Task Forces in the U.S.:

But a closer inspection of the cases brought by JTTFs reveals that most of the prosecutions had one thing in common: The defendants posed little if any demonstrable threat to anyone or anything. According to a study by the Center on Law and Security at the New York University School of Law, only ten percent of the 619 “terrorist” cases brought by the federal government have resulted in convictions on “terrorism-related” charges—a category so broad as to be meaningless. In the past year, none of the convictions involved jihadist terror plots targeting America. “The government releases selective figures,” says Karen Greenberg, director of the center. “They have never even defined ‘terrorism.’ They keep us in the dark over statistics.”

Indeed, Shareef is only one of many cases where the JTTFs have employed dubious means to reach even more dubious ends. In Buffalo, the FBI spent eighteen months tracking the “Lackawanna Six”—a half-dozen men from the city’s large Muslim population who had been recruited by an Al Qaeda operative in early 2001 to undergo training in Afghanistan. Only two lasted the six-week course; the rest pretended to be hurt or left early. Despite extensive surveillance, the FBI found no evidence that the men ever discussed, let alone planned, an attack—but that didn’t stop federal agents from arresting the suspects with great fanfare and accusing them of operating an “Al Qaeda-trained terrorist cell on American soil.” Fearing they would be designated as “enemy combatants” and disappeared into the legal void created by the Patriot Act, all six pleaded guilty to aiding Al Qaeda and were sentenced to at least seven years in prison.

In other cases, the use of informants has led the government to flirt with outright entrapment. In Brooklyn, a Guyanese immigrant and former cargo handler named Russell Defreitas was arrested last spring for plotting to blow up fuel tanks at JFK International Airport. In fact, before he encountered the might of the JTTF, Defreitas was a vagrant who sold incense on the streets of Queens and spent his spare time checking pay phones for quarters. He had no hope of instigating a terrorist plot of the magnitude of the alleged attack on JFK—until he received the help of a federal informant known only as “Source,” a convicted drug dealer who was cooperating with federal agents to get his sentence reduced. Backed by the JTTF, Defreitas suddenly obtained the means to travel to the Caribbean, conduct Google Earth searches of JFK’s grounds and build a complex, multifaceted, international terror conspiracy—albeit one that was impossible to actually pull off. After Defreitas was arrested, U.S. Attorney Roslynn Mauskopf called it “one of the most chilling plots imaginable.”

Using informants to gin up terrorist conspiracies is a radical departure from the way the FBI has traditionally used cooperating sources against organized crime or drug dealers, where a pattern of crime is well established before the investigation begins. Now, in new-age terror cases, the JTTFs simply want to establish that suspects are predisposed to be terrorists—even if they are completely unable or ill-equipped to act on that predisposition. High-tech video and audio evidence, coupled with anti-terror hysteria, has made it effectively impossible for suspects to use the legal defense of entrapment. The result in many cases has been guilty pleas—and no scrutiny of government conduct.

In most cases, because no trial is ever held, few details emerge beyond the spare and slanted descriptions in the indictments. When facts do come to light during a trial, they cast doubt on the seriousness of the underlying case. The “Albany Pizza” case provides a stark example. Known as a “sting case,” the investigation began in June 2003 when U.S. soldiers raided an “enemy camp” in Iraq and seized a notebook containing the name of an imam in Albany—one Yassin Aref. To snare Aref, the JTTF dispatched a Pakistani immigrant named Shahed “Malik” Hussain, who was facing years in prison for a driver’s-license scam. Instead of approaching Aref directly, federal agents sent Malik to befriend Mohammed Hossain, a Bangladeshi immigrant who went to the same mosque as Aref. Hossain, an American citizen who ran a place called Little Italy Pizzeria in Albany, had no connections whatsoever to terrorism or any form of radical Islam. After the attacks on 9/11, he had been quoted in the local paper saying, “I am proud to be an American.” But enticed by Malik, Hossain soon found himself caught up in a government-concocted terror plot. Posing as an arms dealer, Malik told Hossain that a surface-to-air missile was needed for an attack on a Pakistani diplomat in New York. He offered Hossain $5,000 in cash to help him launder $50,000—a deal Hossain claims he never properly grasped. According to Muslim tradition, a witness is needed for significant financial transactions. Thus, the JTTF reached out for Hossain’s imam and the true target of the sting—Aref.

Why Some Terrorist Attacks Succeed and Others Fail

In “Underlying Reasons for Success and Failure of Terrorist Attacks: Selected Case Studies” (Homeland Security Institute, June 2007), the authors examine eight recent terrorist plots against commercial aviation and passenger rail, and come to some interesting conclusions.

From the “Executive Summary”:

The analytic results indicated that the most influential factors determining the success or failure of a terrorist attack are those that occur in the pre-execution phases. While safeguards and controls at airports and rail stations are critical, they are most effective when coupled with factors that can be leveraged to detect the plot in the planning stages. These factors include:

  • Poor terrorist operational security (OPSEC). The case studies indicate that even plots that are otherwise well-planned and operationally sound will fail if there is a lack of attention to OPSEC. Security services cannot “cause” poor OPSEC, but they can create the proper conditions to capitalize on it when it occurs.
  • Observant public and vigilant security services. OPSEC breaches are a significant factor only if they are noticed. In cases where the public was sensitive to suspicious behavior, lapses in OPSEC were brought to the attention of authorities by ordinary citizens. However, the authorities must likewise be vigilant and recognize the value of unexpected information that may seem unimportant, but actually provides the opening to interdict a planned attack.
  • Terrorist profile indicators. Awareness of and sensitivity to behavioral indicators, certain activities, or past involvement with extremist elements can help alert an observant public and help a vigilant security apparatus recognize a potential cell of terrorist plotters.
  • Law enforcement or intelligence information sharing. Naturally, if security services are aware of an impending attack they will be better able to interdict it. The key, as stated above, is to recognize the value of information that may seem unimportant but warrants further investigation. Security services may not recognize the context into which a certain piece of information fits, but by sharing with other organizations more parts of the puzzle can be pieced together. Information should be shared laterally, with counterpart organizations; downward, with local law enforcement, who can serve as collectors of information; and with higher elements capable of conducting detailed analysis. Intelligence collection and analysis are relatively new functions for law enforcement. Training is a key element in their ability to recognize and respond to indicators.
  • International cooperation. Nearly all terrorist plots, including most of those studied for this project, have an international connection. This could include overseas support elements, training camps, or movement of funds. The sharing of information among allies appears from our analysis to have a positive impact on interdicting attack plans as well as apprehending members of larger networks.

I especially like this quote, which echos what I’ve been saying for a long time now:

One phenomenon stands out: terrorists are rarely caught in the act during the execution phase of an operation, other than instances in which their equipment or weapons fail. Rather, plots are most often foiled during the pre-execution phases.

Intelligence, investigation, and emergency response: that’s where we should be spending our counterterrorism dollar. Defending the targets is rarely the right answer.

FBI Knows Identity of Storm Worm Writers

Interesting allegation:

…federal law enforcement officials who need to know have already learned the identities of those responsible for running the Storm worm network, but that U.S. authorities have thus far been prevented from bringing those responsible to justice due to a lack of cooperation from officials in St. Petersburg, Russia, where the Storm worm authors are thought to reside.

I’ve written about Storm here.

Corporate Spying

This is a good article on a new trend in corporate spying: companies like Wal-Mart and Sears have resorted to covert surveillance of employees, partners, journalists, and even Internet users to protect itself from “global threats.”

“Like most major corporations, it is our corporate responsibility to have systems in place, including software systems, to monitor threats to our network, intellectual property and our people,” Wal-Mart spokeswoman Sarah Clark said in a statement in April. Following the Gabbard firing, Wal-Mart said it conducted a review of its monitoring activities. “There have been changes in leadership, and we have strengthened our practices and protocols in this area,” Clark said.

[…]

At a gathering of security specialists in New York City in January of 2006, David Harrison, the former Army military intelligence officer who was hired by Senser to head Wal-Mart’s analytical security research center, provided a rare glimpse into the company’s monitoring operations. Harrison told the gathering Wal-Mart faces a wide range of threats: “A bombing in China, an armed robbery in Brazil, an armed robbery in Las Vegas, another bomb threat, and that was just yesterday,” Harrison said.

To safeguard its employees and operations Wal-Mart has tapped its massive data warehouse of information, now believed to be larger than 4 petabytes (4,000 terabytes), to look for potential threats. It tracks customers who buy propane tanks, for example, or anyone who has fraudulently cashed a check, or anyone making bulk purchases of pre-paid cell phones, which could be tied to criminal activities. “If you try to buy more than three cell phones at one time, it will be tracked,” he reportedly told the audience.

[…]

Gabbard, the Wal-Mart employee fired for recording reporters’ phone calls, said in his interview with The Wall Street Journal that Wal-Mart uses software from Raytheon Oakley Networks to monitor activity on its network. The Oakley product was originally developed for the U.S. Department of Defense.

The Oakley software is so sophisticated it can allow administrators to visually see what types of information are moving across the network, from Excel spreadsheets to job searches on Monster.com, or photos with flesh tones that might indicate a user is viewing pornography.

And this article talks about ex-CIA agents working for corporations:

The best estimate is that several hundred former intelligence agents now work in corporate espionage, including some who left the C.I.A. during the agency turmoil that followed 9/11. They quickly joined private-investigation firms whose U.S. corporate clients were planning to expand into Russia, China, and other countries with opaque business practices and few public records, and who needed the skinny on international partners or rivals.

These ex-spies apply a higher level of expertise, honed by government service, to the cruder tactics already practiced by private investigators. One such ploy is pretexting—obtaining information by pretending to be somebody else. While private detectives have long posed as freelance reporters or job recruiters to get people to talk, former agents have elevated pretexting to an art.

[…]

Similarly, ex-agents have helped popularize the use of G.P.S.-based monitoring devices and long-range cameras for following people around. One corporate-espionage technique comes straight from the C.I.A. playbook. In the constant search for the slightest edge, some hedge funds and investment companies have turned to a handful of private-investigation firms for a tactic that seems to fall between science and voodoo. Called tactical behavior assessment, it relies on dozens of verbal and nonverbal cues to determine whether someone is lying. Signs of potential deception include meandering off topic rather than sticking to the facts and excessive personal grooming, such as nervously picking lint off a jacket. This method was developed by former lie-detector experts from the C.I.A.’s Office of Security, which administers polygraph tests to keep agents honest and verify the stories of would-be defectors.

[…]

Most of the ex-agents’ activities, from surveillance to lie detection, are perfectly legal. In the wake of the 2006 Hewlett-Packard scandal, detectives used pretexting to obtain the private telephone records of company directors, employees, and journalists. In an effort to track leaks to the media, federal law was tightened to prohibit using fraudulent means to obtain telephone records. Financial records were already off-limits. But federal law doesn’t forbid assuming a false identity to get other information—an area that ex-spies exploit.

Still, a few techniques favored by the spies-for-hire do appear to violate privacy statutes. One of these involves using “data haunts,” extreme methods of electronic monitoring such as tracking cell-phone calls and gathering emails by relying on secretly installed software to record computer keystrokes. An ex-C.I.A. agent described a group of his former colleagues who set up shop offshore so that they could tap into telephone calls—a practice prohibited by federal law—outside U.S. jurisdiction. “They call themselves the bad boys in the Bahamas,” he said.

Even some of the legal methods are controversial within the industry. Certain old-school firms won’t stoop to dumpster diving or stealing garbage—which is usually legal as long as the trash is on a curb or other public property—” because they consider it unethical. They say that the prevalence of former intelligence agents in the field and the rise of unscrupulous tactics have tarnished a business that often struggles with its reputation. One longtime investigator complained that he recently lost business to some ex-C.I.A. officers who promised a potential client that they could obtain the phone and bank records of a target—something that is illegal in most cases.

[…]

Current and former employees said Diligence’s ex-spies also held classes in using false identities to obtain confidential information. Ex-employees said it wasn’t unusual for an investigator to have five or six cell phones, each representing a different identity, on his or her desk. And while ex-C.I.A. and former MI5 agents were old hands at such deception, the new initiates sometimes got confused and answered a phone with the wrong name.

All interesting. It seems that corporate espionage has gone mainstream, and the debate is more about how and when.

On a related note, this paragraph disturbed me:

On occasion, Diligence investigators were dispatched to collect garbage from a target’s home or office. In some cases, two former employees said, Diligence hired off-duty or retired police officers to take trash so that they could wave their badges and fend off any awkward questions.

It’s public authority being used for private interests. We see it a lot—off-duty police officers guarding private businesses, for example—and it erodes public trust of authority. In the case above, I’m not even sure it’s legal.

My Open Wireless Network

Whenever I talk or write about my own security setup, the one thing that surprises people—and attracts the most criticism—is the fact that I run an open wireless network at home. There’s no password. There’s no encryption. Anyone with wireless capability who can see my network can use it to access the internet.

To me, it’s basic politeness. Providing internet access to guests is kind of like providing heat and electricity, or a hot cup of tea. But to some observers, it’s both wrong and dangerous.

I’m told that uninvited strangers may sit in their cars in front of my house, and use my network to send spam, eavesdrop on my passwords, and upload and download everything from pirated movies to child pornography. As a result, I risk all sorts of bad things happening to me, from seeing my IP address blacklisted to having the police crash through my door.

While this is technically true, I don’t think it’s much of a risk. I can count five open wireless networks in coffee shops within a mile of my house, and any potential spammer is far more likely to sit in a warm room with a cup of coffee and a scone than in a cold car outside my house. And yes, if someone did commit a crime using my network the police might visit, but what better defense is there than the fact that I have an open wireless network? If I enabled wireless security on my network and someone hacked it, I would have a far harder time proving my innocence.

This is not to say that the new wireless security protocol, WPA, isn’t very good. It is. But there are going to be security flaws in it; there always are.

I spoke to several lawyers about this, and in their lawyerly way they outlined several other risks with leaving your network open.

While none thought you could be successfully prosecuted just because someone else used your network to commit a crime, any investigation could be time-consuming and expensive. You might have your computer equipment seized, and if you have any contraband of your own on your machine, it could be a delicate situation. Also, prosecutors aren’t always the most technically savvy bunch, and you might end up being charged despite your innocence. The lawyers I spoke with say most defense attorneys will advise you to reach a plea agreement rather than risk going to trial on child-pornography charges.

In a less far-fetched scenario, the Recording Industry Association of America is known to sue copyright infringers based on nothing more than an IP address. The accuser’s chance of winning is higher than in a criminal case, because in civil litigation the burden of proof is lower. And again, lawyers argue that even if you win it’s not worth the risk or expense, and that you should settle and pay a few thousand dollars.

I remain unconvinced of this threat, though. The RIAA has conducted about 26,000 lawsuits, and there are more than 15 million music downloaders. Mark Mulligan of Jupiter Research said it best: “If you’re a file sharer, you know that the likelihood of you being caught is very similar to that of being hit by an asteroid.”

I’m also unmoved by those who say I’m putting my own data at risk, because hackers might park in front of my house, log on to my open network and eavesdrop on my internet traffic or break into my computers. This is true, but my computers are much more at risk when I use them on wireless networks in airports, coffee shops and other public places. If I configure my computer to be secure regardless of the network it’s on, then it simply doesn’t matter. And if my computer isn’t secure on a public network, securing my own network isn’t going to reduce my risk very much.

Yes, computer security is hard. But if your computers leave your house, you have to solve it anyway. And any solution will apply to your desktop machines as well.

Finally, critics say someone might steal bandwidth from me. Despite isolated court rulings that this is illegal, my feeling is that they’re welcome to it. I really don’t mind if neighbors use my wireless network when they need it, and I’ve heard several stories of people who have been rescued from connectivity emergencies by open wireless networks in the neighborhood.

Similarly, I appreciate an open network when I am otherwise without bandwidth. If someone were using my network to the point that it affected my own traffic or if some neighbor kid was dinking around, I might want to do something about it; but as long as we’re all polite, why should this concern me? Pay it forward, I say.

Certainly this does concern ISPs. Running an open wireless network will often violate your terms of service. But despite the occasional cease-and-desist letter and providers getting pissy at people who exceed some secret bandwidth limit, this isn’t a big risk either. The worst that will happen to you is that you’ll have to find a new ISP.

A company called Fon has an interesting approach to this problem. Fon wireless access points have two wireless networks: a secure one for you, and an open one for everyone else. You can configure your open network in either “Bill” or “Linus” mode: In the former, people pay you to use your network, and you have to pay to use any other Fon wireless network. In Linus mode, anyone can use your network, and you can use any other Fon wireless network for free. It’s a really clever idea.

Security is always a trade-off. I know people who rarely lock their front door, who drive in the rain (and, while using a cell phone) and who talk to strangers. In my opinion, securing my wireless network isn’t worth it. And I appreciate everyone else who keeps an open wireless network, including all the coffee shops, bars and libraries I have visited in the past, the Dayton International Airport where I started writing this and the Four Points Sheraton where I finished. You all make the world a better place.

This essay originally appeared on Wired.com, and has since generated a lot of controversy. There’s a Slashdot thread. And here are three opposing essays and three supporting essays. Presumably there will be a lot of back and forth in the comments section here as well.

EDITED TO ADD (1/15): There has been lots more commentary.

EDITED TO ADD (1/16): Even more commentary. And still more.

EDITED TO ADD (1/17): Two more.

EDITED TO ADD (1/18): Another. In the beginning, comments agreeing with me and disagreeing with me were about tied. By now, those that disagree with me are firmly in the lead.
