Bruce Schneier talks about security and trust

Filed under: Business, Media, Technology — Tags: , , , — Nicholas @ 12:07

Published on 19 Jun 2013

Human society runs on trust. We all trust millions of people, organizations, and systems every day — and we do it so easily that we barely notice. But in any system of trust, there is an alternative, parasitic, strategy that involves abusing that trust. Making sure those defectors don’t destroy the cooperative systems they’re abusing is an age-old problem, one that we’ve solved through morals and ethics, laws, and all sort of security technologies. Understanding how these all work — and fail — is essential to understanding the problems we face in today’s increasingly technological and interconnected world.

Bruce Schneier is an internationally renowned security technologist and author. Described by The Economist as a “security guru,” he is best known as a refreshingly candid and lucid security critic and commentator. When people want to know how security really works, they turn to Schneier.

Stereotypes of pornography consumers

Filed under: Britain, Media, Technology — Tags: , , , — Nicholas @ 13:05

James Delingpole had far too much fun writing this column:

You may be aware that David Cameron — as part of a secret, Lynton Crosby-inspired operation codenamed Suck Up Shamelessly To The Embittered Authoritarian Killjoy Harpies At Mumsnet — has decreed that as from next year the default option when you sign a contract with your new internet provider will be ‘No porn in this household, thank you. I think it’s a disgrace.’

Superficially (and does this coalition ever think any other way?) I can see this makes a lot of sense. After all, what do a growing national debt, falling living standards, rising inflation, skyrocketing energy prices, out-of-control immigration, Weimar-style money-printing, a burgeoning new housing bubble, a failed health service and a collapsing infrastructure matter when you’ve got the most important problem of our times, so to speak, in hand, viz. blokes sneaking a quick one off the wrist while their missus has popped down to Waitrose to stock up on Mabel Pearman’s Burford Brown eggs, Isigny Ste Mere unsalted butter and that Duchy Originals cider on special offer at just £1.45 a bottle?

According to James, nowadays women are about as likely to go looking for pornography on the internet as men are:

But according to some of my techie friends, this isn’t the case at all. They’re the ones who have to clear up all the viruses which you accidentally invited into your computer along when you were trying to Google the weather and mistakenly typed in ‘Romanian donkey babes xxx hardcore’ instead.

Here’s what one of them has to say: ‘The very worst I came across was a shared houseful of young ladies. It took over eight hours to do just the first pass with the antivirus software. That pass removed over 58,000 pieces of malware and spyware, and just under 2,000 viruses. It took all the next day to finish cleaning their computer. I told them it was the worst case of an infected computer I had ever come across, and one asked how it had happened for it to be so bad. Easy I said. Porn sites. They all went bright red and then the hilarity ensued, as the finger pointing started.’

[…]

I realise, of course, that there are still plenty of puritans out there who feel differently. To them I quote first Thomas Sowell: ‘What is ominous is the ease with which some people go from saying that they don’t like something to saying that the government should forbid it. When you go down that road, don’t expect freedom to survive very long.’ And second, Pastor Niemoller: ‘First they came for the wankers…’.

The real, long-term source of damage to American interests from the NSA revelations

Filed under: Business, Government, Technology, USA — Tags: , , , , , — Nicholas @ 10:10

In The Atlantic, James Fallows explains why the NSA’s digital overreach has likely harmed US long-term interests in many different ways:

In short: because of what the U.S. government assumed it could do with information it had the technological ability to intercept, American companies and American interests are sure to suffer in their efforts to shape and benefit from the Internet’s continued growth.

    American companies, because no foreigners will believe these firms can guarantee security from U.S. government surveillance;

    American interests, because the United States has gravely compromised its plausibility as world-wide administrator of the Internet’s standards and advocate for its open, above-politics goals.

Why were U.S. authorities in a position to get at so much of the world’s digital data in the first place? Because so many of the world’s customers have trusted* U.S.-based firms like Google, Yahoo, Apple, Amazon, Facebook, etc with their data; and because so many of the world’s nations have tolerated an info-infrastructure in which an outsized share of data flows at some point through U.S. systems. Those are the conditions of trust and toleration that likely will change.

The problem for the companies, it’s worth emphasizing, is not that they were so unduly eager to cooperate with U.S. government surveillance. Many seem to have done what they could to resist. The problem is what the U.S. government — first under Bush and Cheney, now under Obama and Biden — asked them to do. As long as they operate in U.S. territory and under U.S. laws, companies like Google or Facebook had no choice but to comply. But people around the world who have a choice about where to store their data, may understandably choose to avoid leaving it with companies subject to the way America now defines its security interests.

Update: Also in the aftermath of Edward Snowden’s revelations, you’d think that Senator Ron Wyden would get the credit he clearly has been deserving all this time:

For many, many years we’ve covered Senator Ron Wyden’s seemingly quixotic attempts to signal to the American public (and press) that the NSA was doing a hell of a lot more surveillance than most people believed, even those who were carefully reading the laws. Because secrecy rules meant that he couldn’t directly reveal what he’d learned while on the Senate Intelligence Committee, he had to issue vague statements, documents and speeches hinting at things that were going on that he couldn’t actually talk about. Of course, now that Ed Snowden leaked a bunch of documents, it’s shown that Wyden was absolutely correct in what was going on (and that the American public wouldn’t like it).

You’d think that would lead people to have a lot more respect for the incredible efforts he went through to alert people to these issues without breaking the secrecy laws. And, in fact, many more people are aware of those efforts. The Washington Post has a nice article about Wyden’s attempts to bring these issues out and to get a real debate going on them.

However, towards the end, the reporter talks to two different former top lawyers at the NSA, who both appear to be really, really angry about Wyden daring to suggest to the public that the NSA wasn’t playing straight with the American public. First up, we’ve got Stewart Baker, the former NSA General Counsel and top Homeland Security official, who is so anti-civil liberties and pro-surveillance that he’s almost a caricature of himself — including claiming that the Boston bombings prove that Americans need less privacy and that civil libertarians complaining about too much surveillance are the real cause for the September 11 attacks.

The return of “lawful access”

Filed under: Cancon, Law, Liberty, Media, Technology — Tags: , , , , — Nicholas @ 07:56

Michael Geist on the Canadian implications of some information that was published in a Buzzfeed article about a Utah ISP and the NSA’s installation of a “little black box” in their network:

The article describes how a Foreign Intelligence Service Act (FISA) warrant allowed the NSA to monitor the activities of an ISP subscriber by inserting surveillance equipment directly within the ISP’s network. The experience in Utah appears to have been replicated in many other Internet and technology companies, who face secret court orders to install equipment on their systems.

The U.S. experience should raise some alarm bells in Canada, since the now defeated lawful access bill envisioned similar legal powers. Section 14(4) of the bill provided:

    The Minister may provide the telecommunications service provider with any equipment or other thing that the Minister considers the service provider needs to comply with an order made under this section.

That provision would have given the government the power to decide what specific surveillance equipment must be installed on private ISP and telecom networks by allowing it to simply take over the ISP or telecom network and install its own equipment. This is no small thing: it literally means that law enforcement (including CSIS) would have had the power to ultimately determine not only surveillance capabilities but the surveillance equipment itself.

While Bill C-30 is now dead, the government may be ready resurrect elements of it. Earlier this month, a cyber-bullying report included recommendations that are lifted straight from the lawful access package.

Ten questions with Evernote CEO Phil Libin

Filed under: Business, Technology — Tags: , , , , — Nicholas @ 09:36

Wired‘s Ryan Tate sat down to talk to Phil Libin of Evernote:

Evernote is known for its eponymous note-taking app, a seemingly modest piece of software that has brought in a heap of money. Evernote has topped 10 million downloads in the iOS and Android app stores and accumulated more than 65 million users across its mobile, web, and desktop versions.

CEO and serial tech entrepreneur Phil Libin used to bristle when people would refer to Evernote as a digital notebook. He sees the product as an extension of the mind, albeit one that’s only about 5 percent complete. These days, though, he’s learned to embrace the pigeonholing. After all, it was humble note-takers who brought Redwood City, California-based Evernote to profitability in 2011 by upgrading en masse to a premium version that includes optical character recognition (handy for pictures of business cards and receipts) and collaborative note editing (great for workgroups).

This year, Evernote is in the red again as the company scales up to reach Libin’s bigger ambition — becoming something like Microsoft Office for mobile devices. Or, as Libin put it in an hourlong interview with WIRED, “like Nike for your mind.”

Evernote’s staff of 330 is divided into teams of no more than eight members — small enough, as Libin sees it, to sit around a dinner table and have a single conversation. No team project can last more than nine months, and none of the teams share any code, which is something close to sacrilege among the software priests of Silicon Valley. One recent sunny Friday, while programmers behind him raced to rewrite the iPhone and iPad versions of Evernote from scratch, we pelted Libin with questions about the past, present, and future of his company.

Snowden is not the story

Filed under: Liberty, Media, Technology — Tags: , , , , — Nicholas @ 10:16

In the Observer, John Naughton makes a few corrections to the way the media is reporting the saga of Edward Snowden and his revelations about the NSA’s global surveillance operations:

Repeat after me: Edward Snowden is not the story. The story is what he has revealed about the hidden wiring of our networked world. This insight seems to have escaped most of the world’s mainstream media, for reasons that escape me but would not have surprised Evelyn Waugh, whose contempt for journalists was one of his few endearing characteristics. The obvious explanations are: incorrigible ignorance; the imperative to personalise stories; or gullibility in swallowing US government spin, which brands Snowden as a spy rather than a whistleblower.

In a way, it doesn’t matter why the media lost the scent. What matters is that they did. So as a public service, let us summarise what Snowden has achieved thus far.

Without him, we would not know how the National Security Agency (NSA) had been able to access the emails, Facebook accounts and videos of citizens across the world; or how it had secretly acquired the phone records of millions of Americans; or how, through a secret court, it has been able to bend nine US internet companies to its demands for access to their users’ data.

Similarly, without Snowden, we would not be debating whether the US government should have turned surveillance into a huge, privatised business, offering data-mining contracts to private contractors such as Booz Allen Hamilton and, in the process, high-level security clearance to thousands of people who shouldn’t have it. Nor would there be — finally — a serious debate between Europe (excluding the UK, which in these matters is just an overseas franchise of the US) and the United States about where the proper balance between freedom and security lies.

These are pretty significant outcomes and they’re just the first-order consequences of Snowden’s activities. As far as most of our mass media are concerned, though, they have gone largely unremarked. Instead, we have been fed a constant stream of journalistic pap — speculation about Snowden’s travel plans, asylum requests, state of mind, physical appearance, etc. The “human interest” angle has trumped the real story, which is what the NSA revelations tell us about how our networked world actually works and the direction in which it is heading.

Follow-up to “First world blogging problems” post

Filed under: Technology — Tags: , , — Nicholas @ 00:01

All good things must come to an end, I guess, so I’ve bid goodbye to the old Tweetdeck, which has been a reliable Twitter client for me for the last several years. When the Twitter corporation took over the original Tweetdeck development, I thought it would be a good thing … until I saw the first release of the “new” Tweetdeck client. It sucked. It was as though the development team’s mission was to find all the good features of the old Tweetdeck and comprehensively ruin them. If that was the case, they succeeded terribly well.

I stuck with the old version of Tweetdeck until it finally stopped working earlier this week. Right now, I’m trying out Janetter, which has been relatively painless to install and configure, and replaces most of the functionality that Tweetdeck used to have. Hopefully, it’ll be around as long as the old Tweetdeck was.

First world blogging problems

Filed under: Administrivia, Technology — Tags: , , , — Nicholas @ 08:48

I use a few tools to come up with items to post on the blog. The two most useful are Twitter and RSS. I’d been using Google Reader for my RSS needs until it was shut down at the beginning of July, so I switched to The Old Reader and it has been working quite well as a direct Google Reader replacement. Earlier this week, TOR had a server meltdown and multiple failures of drives while attempting to recover. As of this morning, they’re still trying to get back online and (hopefully) recover all the data. Fortunately, I’ve also been testing Newsvibe for RSS, and it’s still working well … but has a different set of feeds than TOR.

My other main tool, Twitter, seems to be having some issues today … or it might just be that my old Twitter client is finally giving up the ghost. I’ve been using the desktop TweetDeck client for years, but I really disliked the “new” version of the tool introduced when TweetDeck was taken over by Twitter itself. Over the last several months, the old client (version 0.38.2) has been slowly losing bits of functionality — for example, sometime in the last week, I lost the ability to send a direct message from Tweetdeck, and earlier this year it became impossible to use the “old” retweet method and more recently to retweet at all.

Today, when I started up the client, it was unable to retrieve any data from earlier this morning. This might be a general issue with the Twitter API or it might be yet another bit of creeping feature-fail. It’s picking up new Twitter posts, but one of the more useful features was that it would also collect tweets from my several lists that had been posted overnight. This morning, only the main feed column in Tweetdeck is being populated, the rest (Mentions, Direct Messages, various list and search columns) are empty.

Old Tweetdeck

I may need to shop around for a new Twitter client. Either way, it puts a crimp in my usual blogging habits.

Real competition? In our mobile phone market? It’s less likely than you think

Filed under: Business, Cancon, Government, Technology — Tags: , , , — Nicholas @ 09:31

Canada’s mobile telephone market is a rigged oligopoly of three major companies and a few minor players. One of the big three, Telus, has opened a new campaign against the federal government’s tentative gestures towards allowing a more competitive mobile phone market for Canadians. Michael Geist has the details:

Yesterday, Telus CEO Darren Entwistle was campaigning at the Globe and Mail and National Post, warning of a “bloodbath” if the government sticks with its commitment to allow for a set-aside of spectrum for new entrants such as Verizon. Telus is concerned that a set-aside would allow Verizon to purchase two of the four available blocks, leaving the big three to fight it out over the remaining two blocks. Telus emphasized its prior investments in arguing for a “level playing field” in the auction.

Yet to borrow Telus’ phrase — “scratch the surface of their arguments and get to the facts” — and it becomes clear the fight is not about level playing fields since new entrants have been at a huge disadvantage for years in Canada. Indeed, even with a spectrum set-aside, there would not be a level playing field as companies such as Telus would have big advantages that include restrictions on foreign ownership for broadcast distribution (thereby blocking Verizon from offering similar bundled services), millions of subscribers locked into long term contracts, far more spectrum than Verizon would own, and its shared network with Bell that has saved both companies millions of dollars.

While the companies frame their arguments around level playing fields, the real goal is simply to keep competition out of the country. For Verizon (or any major new entrants), a spectrum set-aside will be crucial since it is the only way to obtain sufficient spectrum (when combined with the existing spectrum from Wind Mobile and Mobilicity) to establish a viable fourth wireless network that could compete directly with the big three incumbents. If Telus gets their way, the removal of the set-aside would kill the government’s stated goal of a viable fourth carrier since there would be little reason for Verizon to enter the country only to face many of the same disadvantages that has hamstrung the smaller new entrants.

[…]

Make no mistake: the Telus lobbying campaign will be joined by Bell and Rogers as the three companies spend millions of dollars in advertising and lobbying to keep the Canadian market free from much needed competition (the Wire Report reports that ten board members each from Telus and BCE have registered to lobby the government on spectrum). The government has insisted that it will do whatever is necessary to ensure greater competition and consumer choice in the wireless sector. The potential Verizon entry into Canada — undoubtedly conditioned on a spectrum set-aside — is precisely what is needed. In this case, sticking with its policy by siding with consumers and greater competition has the dual advantage of being both good policy and good politics.

QotD: The war on general-purpose computing

Filed under: Liberty, Quotations, Technology — Tags: , , , — Nicholas @ 00:01

As we wait for dessert, I ask him about his recent speeches at technology conferences discussing the “war on general purpose computing”. He runs through the argument with practised fluency. Computers are by nature general-purpose machines. It’s impossible to make a computer that does all the kinds of things we want computers to do yet is somehow disabled from making copies of copyrighted material, or viewing child pornography, or sending instructions to a 3D printer to produce a gun.

“Oh my God, that’s good,” says Doctorow after his first mouthful of crumble. My peanut butter shortbread is fantastic too, if absurdly calorific. We are interrupted only by another waiter dropping a tray of glasses.

He continues with the argument. The impossibility of making limited-purpose computers won’t stop governments or corporations trying to put on the locks, or changing laws to try to make those locks effective. But the only way these limits can possibly work is subterfuge: computers therefore tend to contain concealed software that spies on what their users are trying to do. Such software is inevitably open to abuse and has often been abused in the past.

Digital rights management systems intended to prevent copying have been hijacked by virus-writers. In one notorious case, the Federal Trade Commission acted against seven computer rental companies and the software company that supplied them, alleging that the rental companies could activate hidden software to grab passwords, bank account details and even switch on the webcam to take photos of what the FTC coyly calls “intimate activities at home”. As computers surround us — in our cars, our homes, our pacemakers — Doctorow is determined to make people realise what’s at stake.

Next up on our agenda of things to panic about is “peak water”

Filed under: Economics, Environment, Technology — Tags: , , , , — Nicholas @ 00:02

sp!ked editor Rob Lyons explains that “peak water” just isn’t something to worry too much about:

Disappointed by the failure of the peak-oil disaster to come to fruition, our doom-mongering, Malthusian friends have alighted on other scary narratives to confirm their suspicions of humanity as a rapacious blight on the planet. Their latest is ‘peak water’.

On the face of it, peak water is a boneheaded concept on a planet where two thirds of the surface is covered in, er, water. According to the US Geological Survey, there are 332 million cubic miles of water on Earth. What we tend to need, however, is not sea water but fresh water, of which there is much less: nearer 2.5 million cubic miles. And much of that is too deep underground to be accessed. Surface water in rivers and lakes is a small fraction of overall fresh water: 22,339 cubic miles. Handily, though, natural processes cause sea water to evaporate and form clouds, which then dump their contents on to land — so in most populated parts of the world there is currently sufficient water to supply our needs in an endlessly renewable way. As for the future, it is clear there is no shortage of H2O on the planet. What we really have is a shortage of cheap energy and the necessary technology to take advantage of the salinated stuff.

The ‘peak water’ theorists focus on groundwater supplies that are either being used faster than they are replenished, or supplies that are not replenished at all: so-called ‘fossil water’. According to leading environmentalist Lester Brown, writing in the Guardian last weekend, the rapid exhaustion of these supplies in some parts of the world is leading to the decline of food production. And at a time of fast-growing populations, this apparently promises disaster for these countries.

But often, the problem is a political rather than a practical one. [. . .]

In reality, all of the fixes that apply to peak oil also apply to peak water. New technology may make water desalination far cheaper than it is now, a claim being made for new water filtration methods based on nanotechnology. Better use of water in irrigation, through careful management of when and how water is applied to crops, could cut usage dramatically — something that is already happening in dry countries such as Israel and Australia and in parts of the US. Current uses of water, like flush toilets, may be superseded in places where water is in high demand. Through civil engineering projects, water can be shifted from places where it is plentiful to places where it is needed most, something societies have been doing for thousands of years.

How Avro salvaged a bad design to create the Lancaster bomber

Filed under: Britain, History, Technology, WW2 — Tags: , — Nicholas @ 00:01

In Samizdata, Brian Micklethwait goes back to his Airfix modelling days to rediscover his admiration for Avro’s Lancaster bomber. In the process, he discovers just how strange the evolution of that aircraft actually was:

In the late 1930s, believing that bombers would always get through and that they therefore had to have lots of bombers or lose the war, British Air Officialdom had two ideas about how to build a bomber. They accordingly announced two specifications, which different potential bomber-makers were invited to meet with their designs. They wanted a two engined bomber, like those that the Germans bombed Britain with in 1940 but better, or like the Wellington but better. And they wanted a much bigger four engined bomber, such as the Germans never got around to building, and like … well, like the Avro Lancaster.

So, the Lancaster was Avro’s answer to the second requirement? Actually, no. Or, not at first. Britain ended up with three four-engine heavy bombers, the Short Stirling, the Handley Page Halifax, and the Lancaster. But strangely, by far the worst of these three, the Short Stirling, was the only one of the three that was all along intended to be a four-engine bomber. Both the Halifax and the Lancaster started out as answers to the two-engine specification rather than the four-engine one.

[. . .]

In particular, all the work that Avro had done improving, as they had hoped, the fuselage of the Manchester, which had done nothing to improve the Manchester, suddenly came into its own in the new configuration. Ever since I built my Airfix Lancaster as a child, I have wondered about the oddity of that Lancaster fuselage. Simply, this fuselage seemed too small for the airplane as whole. And the wings seemed too big. Not ugly exactly, in fact not ugly at all, but nevertheless a bit like the arms of one of those misshapen body builders with excessive biceps. My Lancaster photo (above) even shows how the wings between the fuselage and the inner two engines go straight out rather than tapering, as if these wings were only widened late on in the design process. Now, all that makes sense. The Lancaster’s fuselage began life as the fuselage of a smaller airplane. No wonder it looked to me too small. It was too small. The Lancaster’s wings look stretched because they were stretched. It is only now, after half a century and more of gazing at the Lancaster, that one looks at the Manchester, and sees its fuselage as too big and its wings as too small.

The birth of the Lancaster illustrates a general point about making airplanes, which explains why successful airplanes often fly on for so long. Consider the airborne WW2 mega-hit, the DC-3 (aka the Dakota), and then later the big Boeings, the B-52 and the 747. The Lancaster didn’t last as long as those hardy perennials, because propeller driven heavy bombers were soon replaced by jet bombers (like the B-52) and by intercontinental ballistic missiles. But even the Lancaster flew on for many decades, in the only slightly altered form of its close cousin, the Avro Shackleton, which only went out of service in 1991!

New diesel engine technology to erase the memory of Oldsmobile diesels

Filed under: Technology — Tags: , — Nicholas @ 09:30

The Economist has a glowing overview of new diesel engines for cars:

NOT to belittle the success Tesla Motors has had with its Model S luxury electric car — outselling its petrol-powered equivalents since being launched last year — the prospects for battery-powered vehicles generally may never shine quite as bright again. Babbage believes their day in the sun is about to be eclipsed by, wait for it, the diesel engine.

Surely not that dirty, noisy, smelly, lumbering lump of a motor that was difficult to start in the winter? Certainly not. A whole new generation of sprightly diesels — developed over the past few years — bear no resemblance to your father’s clattering, oil-burner of an Oldsmobile. It is no exaggeration to say that, with its reputation for unreliability and anaemic performance, the Olds 4.3-litre diesel from the late 1970s single-handedly destroyed the reputation of diesel engines in America for decades to come. Quite possibly, it also contributed to Oldsmobile’s own demise.

Later this year, Americans will get their first chance to experience what a really advanced diesel is like — and why Europeans opt for diesels over hybrids, plug-in electrics and even petrol-powered cars. The leader of the new pack is the Mazda 6, completely redesigned for 2014, with the choice of either a 2.5-litre four-cylinder petrol engine or a 2.2-litre turbo-charged diesel. The diesel has 30% better fuel economy and provides oodles more pulling power. Good as the petrol version is, motorists who choose it over the diesel will miss out on a lot.

[. . .]

With its old 1.4-litre diesel engine, the Volkswagen Polo still holds the record for being the most frugal non-electric car in Britain and the rest of Europe — with a fuel economy on the combined cycle of just 3.8 litres/100km (equivalent to 61.9 miles per US gallon). The Toyota Prius hybrid? A lowly twentieth on the league table of the most economical fuel-sippers, with 4.2 litres/100km, along with higher emissions of carbon dioxide. The 19 cars having better fuel economy than the Prius hybrid are all clean diesels.

Babbage fully expects the new generation of clean, low-compression diesels to raise the fuel-economy bar by a further 20% or more. That will put diesels on much the same footing — on an equivalent miles-per-gallon basis — as many of the electric vehicles available today. Their big advantage will be that they will come with none of the range anxiety and recharging difficulties to worry about. Roll on the day.
