Net accesses …

So, I’m always excited about CanSecWest, and I was yesterday, as I got ready.  I went to do a last minute download of email.  (Yes, the conference provides wireless, and it usually works, after a few initial glitches.  But I like to avoid risks, and I like to have most of my stuff with me on my machine.)

I could pull the email off my main account.  (I have multiple email addresses with Shaw.)  But I couldn’t get any email off the subsidiary accounts.  In order to check if this was some setting gone wrong on my MUA I tried the Web interface.  Same result: I could get at my main account, but not the subsidiary accounts.

Later in the day, at the conference, I was able to access all the accounts.  But I found that, while my main account was still accessible though the original interface, suddenly all the others were using a new “Webmail 2.0.”

I thought this was kind of odd, so I reported this to Shaw through their “ShawHelp” account on Twitter.  You can’t explain a lot in 140 characters, so we passed a few “direct messages” back and forth.

I have previously mentioned that Shaw’s support is not the best, and their attitude to security could use some work.  (As a side result of this, a friend has provided me with an emergency proxy for outbound email.  I tried it this morning, and, unlike Shaw, which requires that you be on their network before you get access to your email, it works from CanSecWest.)  So I shouldn’t have been shocked when I got a message from ShawHelp saying … well, let me quote it:

“Not seeing issues with either of them. You can’t log into cissp? What is password so we can take a look? ^LL”

I had forgotten this.  In the old days, when I stilled tried to call Shaw support when I had a problem, I frequently got asked for my password.  Since I won’t give them my password (what do you think I am, a normal user?), that usually ended any attempt on their part to deal with the problem.

So, here we are, some years later, and Shaw is still asking their customers for passwords.  How many years have we been telling people, “customer support will never ask you for your password”?

On a very slightly positive note, I can say that, two months after they announced it, the Shaw Wifi AP in Lynn Valley is finally operating.

(I suppose I shouldn’t bash too hard on Shaw.  Their tech support and security is abysmal, but the service only goes down about once a quarter.  The other day I was at the barbershop.  They are putting in service through the other major provider in our area, Telus.  Telus’ initial installation had only given them partial access, so they called in Telus’ support.  The support tech managed to shut off access completely, and had been coming back, sporadically, for over a week, without success.)  (Yes, I did manage to get them partial access back …)

Social authentication and solar storms

Well, I thought it was ironic that the biggest solar storm in years is hitting the earth tonight … while CanSecWest is on …

So far today we have had talks on security (and vulnerabilities) during the boot process, a talk on pen testing (and the presenter seemed to be alternately talking about how to choose a pen tester, and how to do pen testing), and social authentication.

The social authentication talk was by Alex Rice from Facebook.  He noted that, even though Facebook only challenges a small fraction of a percent of logins, given the user base that means more then a million every day.  When a login is challenged, a standard response has been the good old “security questions”: mother’s maiden name, birthdate, and other pieces of information that might not be too hard for someone intent on breaking into your account to find out.

Alex went through the limitations of security questions, and then moved to other possibilities.  Security questions comes under the heading of “things you know,” so they looked at “things you have.”  For example, you have to have an email address, so there is the possibility of a challenge sent to your email.  (Google, of course, figures that everyone in the world has a cell phone that can receive text messages.)

Recently, Facebook has started to use the photos that people post on their pages, particularly those that have been tagged.  Basically, if your login gets challenged, you will be shown a series of pictures, and you should be able to identify who is, or is not, in the picture, out of your list of friends.  This is the subject of a blog post noting that it isn’t perfect.

There are additional problems.  As the post notes, the situation is less than ideal if you have a huge number of “friends.”  (As Bruce Schneier’s new book notes, if you have more than 150 friends, you probably aren’t friends with many of them.)  Even if you do know your “friends,” there is nothing to say that any given picture of them will be recognizable.  In fact, since the system relies on tagging, there are going to be pictures of weird objects that people have deliberately tagged as themselves, in joking fashion.

Therefore, this system is definitely not perfect, as the questions at the end pointed out.  Unfortunately, Alex had passed, rather quickly, over an important point.  The intent of the system, in Facebook’s opinion, was to reduce the amount of account spam sent via accounts that had been compromised.  In that regard, the system probably works very well.  False logins get challenged.  Some of the challenges are false positives.  The photo system is a means of allowing a portion (a fairly large portion, probably) of users to recover their accounts quickly.  For the remaining accounts, there are other means to recover the account, even though these are more time-consuming for both Facebook and the user.  This system does reduce the total amount of time spent by both users (in the aggregate, even if individual users may feel hard done by) and Facebook.

Congrats to UNC Charlotte

Winner!

 

I had the chance to hang out at the SECCDC yesterday at Kennesaw State Univ.  For those not familiar with these events (I wasn’t either, until yesterday), you have colleges who bring in teams to defend against a ‘red team’.  UNC Charlotte defended their network better than the other colleges.  It was interesting to see these schools throwing in block filters, redirects, etc. on the fly.  Impressive from a bunch of college students.  The red team was equally impressive.  There wasn’t a box that they didn’t, at some point, root thoroughly…

 

One interesting note.  During the competition, there was a full power outage.  UPSes died.  Images were lost.  Router configs were killed.  It generally set the entire competition back a few hours (at least).  Just a reminder that physical security is every bit as important as the logical security….

CanSecWest

I always look forward to CanSecWest.  Usually cutting edge stuff.  Some of it incomprehensible, some of it interesting, some very entertaining.

Every year is a different program, of course, but every year has some changes to the setup, as well.  This year is the latest I can remember them opening the doors to the ballroom/theatre, but it was also one of the earliest in terms of starting the registrations.

Between getting registered and getting in to the room there’s some time to mingle.  It was nice to see old friends, including some whose presence surprised me.  Also nice to meet a few new people.

It’s always interesting who you run into at CanSecWest.  One friend, on his first time out, sat down next to a nice chap, and got to talking.  Said chap shortly asked my friend to mind his computer for the next little while, then walked up to the front and was introduced as the next speaker, Charlie Miller.  Miller is a bit of a fixture at the event, as he tends to win the Pwn2Own contest year after year.  You’ve probably heard of his escapades in other areas.

(As I say, lots of nice people here.  However, this is definitely a conference on the geek end of the spectrum, and you can often count on running into people whose “people skills” could use work.  It makes starting up conversations with strangers possibly more surprising than usual  :-)

Not as many vendors at CanSecWest as at other conferences.  Some interesting ones this year: one company doing managed security and reselling.  They are looking at the enterprise and government market, and I suspect they may be at the wrong conference.  Adobe is here: they seem to be trying to overcome the perception of them as the problem.  A number of companies appear to be primarily interested in recruiting.  (If they are really serious about it, they might have sent more technical people: a number of tables are staffed by sales people who are having difficulty talking to the geeks they are trying to recruit.)

As usual, getting connected to the CanSecWest network was a bit of a challenge, but I seem to be on now  :-)

Michelangelo date

OK, having now had this conversation twice, I’ve gone back to the true source of all wisdom on all things viral, “Viruses Revealed.”  I got it off my shelf, of course, but some helpful vxer (who probably thought he was going to harm our sales) posted it on the net, and saved David and I the bother.  (Remember, this guy is a vxer, so that page may not be entirely safe.)

Michelangelo is covered between pages 357 and 361, which is slightly over halfway through the book.  However, since I guess he’s missed out the index and stuff, it turns out to be at about the 3/4 mark on the page he’s created.

Anyway, Michelangelo checks the date via Interrupt 1Ah.  many people did not understand the difference between the MS-DOS clock and the system clock read by Interrupt 1Ah. The MS-DOS DATE command did not always alter the system clock. Network-connected machines often have “time server” functions so that the date is reset to conform to the network. The year 1992 was a leap year, and many clocks did not deal with it properly. Thus, for many computers, 6th March came on Thursday, not Friday.

Michelangelo

Graham Cluley, of Sophos and Naked Security, posted some reminiscences of the Michelangelo virus.  It brought back some memories and he’s told the story well.

I hate to argue with Graham, but, first off, I have to note that the twentieth anniversary of Micelangelo is not tomorrow (March 6, 2012), but today, March 5.  That’s because 1992 was, as this year is, a leap year.  Yes, Michelangelo was timed to go off on March 6th every year, but, due to a shortcut in the code (and bugs in normal comptuer software), it neglected to factor in leap years.  Therefore, in 1992 many copies went off a day early, on March 5th.

March 5th, 1992, was a rather busy day for me.  I was attending a seminar, but kept getting called out to answer media enquiries.

And then there was the fact that, after all that work and information submitted to the media in advance, and creating copies of Michelangelo on a 3 1/2″ disk (it would normally only infect 5 1/4″s) so I could test it on a safe machine (and then having to recreate the disk when I accidentally triggered the virus), it wasn’t me who got my picture in the paper.  No, it was my baby brother, who a) didn’t believe in the virus, but b) finally, at literally the eleventh hour (11 pm on March 4th) decided to scan his own computer (with a scanner I had given to him), and, when he found he was infected, raised the alarm with his church, and scanned their computers as well.  (Must have been pretty close to midnight, and zero hour, by that time.)  That’s a nice human interest story so he got his picture in the paper.  (Not that I’m bitter, mind you.)

I don’t quite agree with Graham as to the infection rates.  I do know that, since this was the first time we (as the nascent antivirus community) managed to get the attention of the media in advance, there were a great many significant infections that were cleaned off in time, before the trigger date.  I recall notices of thousands of machines cleaned off in various institutions.  But, in a sense, we were victims of our own success.  Having got the word out in advance, by the trigger date most of the infections had been cleaned up.  So, yes, the media saw it as hype on our part.  And then there was the fact that a lot of people had no idea when they got hit.  I was told, by several people, “no, we didn’t get Michelangelo.  But, you know, it’s strange: our computer had a disk failure on that date …”  That was how Michelangelo appeared, when it triggered.

I note that one of the comments wished that we could find out who created the virus.  There is strong evidence that it was created in Taiwan.  And, in response to a posting that I did at the time, I received a message from someone, from Taiwan, who complained that it shouldn’t be called “Michelangelo,” since the real name was “Stoned 3.”  I’ve always felt that only the person who wrote that variant would have been that upset about the naming …

Grandparent scams are still around

No, I didn’t get hit.  Someone even older than I am (although he’s got fewer grandchildren) almost got hit.  Twice.

This is not a stupid guy.  He still runs his own investment company.  A few years ago he recounted a weird call that he thought came from one of his grandkids-in-law.  Everybody who heard the story recognized it for what it was, particularly when it was determined that the grandkid-in-law in question, who does travel a lot, had never made the call.  The scam was explained to the call recipient.

Well, today he sent his whole family into an uproar.  He’d got another call, and seems to have been one phone call away from wiring off $2500.  Fortunately, a couple of family members determined what was happening, in time, and explained the situation.  Again.

Let me try to explain a bit how this works.

The recipient gets a phone call.

Recipient: [answers phone] Hello?
Caller: Grandpa?
Recipient: Is that you, Mary?

OK, at this point the caller knows that whoever answered the phone has a grandchild named “Mary.”  Allow me to theorize why this is the grandparent scam.  Many (older) people may have more grandchildren than they have children, so the odds of hitting someone with a grandchild of the same gender as the caller increase.  Also, most people don’t know their grandchildren, and the doings of said grandchildren, as well as that of their kids.

The fraudsters who make these calls may do it at random, or they may have bought calling lists of those with interests, demographic information, or medication purchasing patterns indicating that they are older.  These calls may also be targeted at geographic areas with a higher proportion of retired people.

Caller: Yeah.
Recipient: Gee, your voice sounds different/that doesn’t sound like you.
Caller: I’m not feeling well/have a cold.

This answer serves two purposes: it explains the differences in voice (although it might not explain an Asian, Russian, or south Asian accent), and also calls on the sympathy of the recipient.

R: That’s too bad.
C: Yeah.  Actually grandpa, [caller launches into story of woe, ending with a requirement for funds for a) medical services, b) legal fees or bail, c) documentation expenses, d) travel expenses, e) etc.]

This particular call added a few refinements.  The explanation ended with a plea that this situation was all very embarrassing, and so would grandpa please not let anyone know.  Grandpa apparently complied with this request: grandpa did do some checking with the family to try and find the grandchild, and, coyly, wouldn’t tell what was going on.  It wasn’t until a) a few family members had had frustrating attempts to find out what the calls were about, and b) the grandchild had been found (well, but busy with an event for one of the great-grandchildren) that the whole story came out.

Fortunately, there was a second refinement.  In an attempt to add verisimilitude to an otherwise bald and unconvincing narrative, the caller had finished with the statement that a lawyer would be calling to make arrangements for the money transfer.  Lawyers are trustworthy, of course (no laughing down there in the cheap seats), and the fact that you can no more authenticate the person who claims to be a lawyer than the person who claims to be your grandchild is probably lost on most people.

I say “fortunately,” because the calls grandpa made to the family probably blocked the second call, at least for a while.  It is quite possible that the scammer or scammers, hitting a busy signal a couple of times, suspected that calls were being made to family, and cut their losses rather than carry on with a now likely compromised scam.

This is not a new scam.  It’s a variation on 419s, which were, themselves, variations on the postal mail based “Nigerian” scam, which was a variation on the “Spanish prisoner” scam going back to the middle ages (which was probably based on a similar and even older scam).  But the scam is widespread, targets generosity rather than greed, and seems to be somewhat resistant to eradication.

Please raise this issue with, and explain it to, older friends and relatives.  The media reports on the scam tend to be minimal, and don’t explain how easy, and likely, it is to give away information in what you think is normal conversation.

Oh, and just to conclude, when you answer the phone and someone says “Grandpa?” or “Grandma?”, the correct answer is, “Who’s speaking, please?”

Paper safe

I first saw this, appropriately enough, on Improbable Research.  It’s appropriate, because, when you see it, first it makes you laugh.  Then it makes you think.

This guy has created a paper safe.  Yeah, you got that right.  A safe, made out of paper.  No, not special paper: plain, ordinary paper, the kind you have in your recycling bin.  He’s even posted a video on YouTube showing how it works.

Right, so everyone’s going to have a good laugh, yes?  Paper isn’t going to provide any protection, right?  It’s a useless oddity, of interest only to those with an interest in origami, and more free time on their hands than any security professional is likely to get.

Except, then you start thinking about it (if you are any kind of security pro.)  First off, it’s a nice illustration of at least one form of combination lock.  And then you realize that the lock is going to be useless unless it’s obscured.  So that brings up the topic of maybe security-by-obscurity does have a function sometimes.

Then you start thinking that maybe it isn’t great as a preventive control, but it sure works as a detective control.  Yeah, it’s easy to smash and get out whatever was in there.  But it’ll sure be obvious if you do.

So that brings up different types of controls, and the reasons you might want different controls in different situations, and whether some perfectly adequate controls may be a) overkill, or b) useless under certain conditions.

It’s not just a cute toy.  It’s pretty educational, too.  No, I’m not going to keep my money in it.  But it makes you think …

The “Man in the Browser” attack

Gizmodo reports:

New “Man in the Browser” Attack Bypasses Banks’ Two-Factor Authentication Systems

Except there is nothing new about this attack. OWASP documented it in 2007 and it was widely known that malware writers used it to bypass 2-factor authentication.

More from Gizmodo:

Since this attack has shown that the two-factor system is no longer a viable defense, the banking industry may have to adopt more advanced fraud-detection methods

Given that this has been going on for more than 5 years, it’s obvious that banks already have adopted more advanced fraud detection methods.

So why are they forcing you to carry around tokens and one-time passwords that make it awkward and uncomfortable to use your own money as you wish?

Because with only few exceptions, banks’ security guys are not interested in making your life comfortable. The more you suffer, the more you think they are secure.

Maybe it’s time to ask for accountability? Which of their so-called security features is really for security, and which is for CYA or ‘make-the-regulator-happy’?

C-30

C. S. Lewis wrote some pretty good sci-fi, some excellent kids books (which Disney managed to ruin), and my favourite satire on the commercialization of Christmas.  Most people, though, would know him as a writer on Christianity.  So I wonder if Stephen Harper and Vic Toews have ever read him.  One of the things he wrote was, “It would be better to live under robber barons than under omnipotent moral busybodies.”

Bill C-30 (sometimes known as the Investigating and Preventing Criminal Electronic Communications Act, sometimes known as the Protecting Children from Internet Predators Act, and sometimes just known as “the online spy bill”) is heading for Committee of the Whole.  This means that some aspects of it may change.  But it’ll have to change an awful lot before it becomes even remotely acceptable.

It’s got interesting provisions.  Apparently, as it stands, it doesn’t allow law enforcement to actually demand access to information without a warrant.  But it allows the to request a “voluntary” disclosure of information.  Up until, law enforcement could request voluntary disclosure, of course.  But then the ISP would refuse pretty much automatically, since to provide that information would breach PIPEDA.  So now that automatic protection seems to be lost.

(Speaking of PIPEDA, there is this guy who is being tracked by who-knows-who.  The tracking is being done by an American company, so they can’t be forced by Canadian authorities to say who planted the bug.  But the data is being passed by a Canadian company, Kore Wireless.  And, one would think, they are in breach of PIPEDA, since they are passing personal information to a jurisdiction [the United States] which basically has no legal privacy protection at all.)

It doesn’t have to be law enforcement, either.  The Minister would have the right to authorize anyone his (or her) little heart desires to request the information.

Then there is good old Section 14, which allows the government to make ISPs install any kind of surveillance equipment the government wants, impose confidentiality on anything (like telling people they are being surveilled), or impose any other operational requirements they want.

Now, our Minister of Public Safety (doesn’t that name just make you feel all warm and 1984ish?), Vic Toews, has been promoting the heck out of the bill, even though he actually doesn’t know what it says or what’s in it.  He does know that if you oppose C-30 you are on the side of child pornographers.  This has led a large number of Canadians to cry out #DontToewsMeBro and to suggest that it might be best to #TellVicEverythingRick Mercer, Canada’s answer to Jon Stewart and famous for his “rants,” has weighed in on the matter.

As far as Toews and friends are concerned, the information that they are after, your IP address and connections, are just like a phone book.  Right.  Well, a few years back Google made their “phone book” available.  Given the huge volume of information, even though it was anonymized, researchers were able to aggregate information, and determine locations, names, interests, political views, you name it.  Hey, Google themselves admit that they can tell how you’re feeling.

But, hey, maybe I’m biased.  Ask a lawyer.  Michael Geist knows about these things, and he’s concerned.  (Check out his notes on the new copyright bill, too.

The thing is, it’s not going to do what the government says it’s going to do.  This will not automatically stop child pornography, or terrorism, or online fraudsters.  Hard working, diligent law enforcement officers are going to do that.  There are a lot of those diligent law enforcement officers out there, and they are doing a sometimes amazing job.  And I’d like to help.  But providing this sort of unfiltered data dump for them isn’t going to help.  It’s going to hurt.  The really diligent ones are going to be crowded out by lazy yahoos who will want to waltz into ISP offices and demand data.  And then won’t be able to understand it.

How do I know this?  It’s simple.  Anyone who knows about the technology can tell you that this kind of access is 1) an invasion of privacy, and 2) not going to help.  But this government is going after it anyway.  In spite of the fact that the Minister responsible doesn’t know what is in the bill.  (Or so he says.)  Why is that?  Is it because they are wilfully evil?  (Oh, the temptation.)  Well, no.  These situations tend to be governed by Hanlon’s Rzor which, somewhat modified, states that you should never attribute to malicious intent, that which can adequately explained by assuming pure, blind, pig-ignorant stupidity.

Thrive”

Chapter one is what would ordinarily constitute an introduction or preface to the book.  Schneier states that the book is about trust: the trust that we need to operate as a society.  In these terms, trust is the confidence we can have that other people will reliably behave in certain ways, and not in others.  In any group, there is a desire in having people cooperate and act in the interest of all the members of the group.  In all individuals, there is a possibility that they will defect and act against the interests of the group, either for their own competing interest, or simply in opposition to the group.  (The author notes that defection is not always negative: positive social change is generally driven by defectors.)  Actually, the text may be more about social engineering, because Schneier does a very comprehensive job of exploring how confident we can be about trust, and they ways we can increase (and sometimes inadvertantly decrease) that reliability.

Part I explores the background of trust, in both the hard and soft sciences.  Chapter two looks at biology and game theory for the basics.  Chapter three will be familiar to those who have studied sociobiology, or other evolutionary perspectives on behaviour.  A historical view of sociology and scaling makes up chapter four.  Chapter five returns to game theory to examine conflict and societal dilemmas.

Schneier says that part II develops a model of trust.  This may not be evident at a cursory reading: the model consists of moral pressures, reputational pressures, institutional pressures, and security systems, and the author is very careful to explain each part in chapters seven through ten: so careful that it is sometimes hard to follow the structure of the arguments.

Part III applies the model to the real world, examining competing interests, organizations, corporations, and institutions.  The relative utility of the four parts of the model is analyzed in respect to different scales (sizes and complexities) of society.  The author also notes, in a number of places, that distrust, and therefore excessive institutional pressures or security systems, is very expensive for individuals and society as a whole.

Part IV reviews the ways societal pressures fail, with particular emphasis on technology, and information technology.  Schneier discusses situations where carelessly chosen institutional pressures can create the opposite of the effect intended.

The author lists, and proposes, a number of additional models.  There are Ostrom’s rules for managing commons (a model for self-regulating societies), Dunbar’s numbers, and other existing structures.  But Schneier has also created a categorization of reasons for defection, a new set of security control types, a set of principles for designing effective societal pressures, and an array of the relation between these control types and his trust model.  Not all of them are perfect.  His list of control types has gaps and ambiguities (but then, so does the existing military/governmental catalogue).  In his figure of the feedback loops in societal pressures, it is difficult to find a distinction between “side effects” and “unintended consequences.”  However, despite minor problems, all of these paradigms can be useful in reviewing both the human factors in security systems, and in public policy.

Schneier writes as well as he always does, and his research is extensive.  In part one, possibly too extensive.  A great many studies and results are mentioned, but few are examined in any depth.  This does not help the central thrust of the book.  After all, eventually Schneier wants to talk about the technology of trust, what works, and what doesn’t.  In laying the basic foundation, the question of the far historical origin of altruism may be of academic philosophical interest, but that does not necessarily translate into an
understanding of current moral mechanisms.  It may be that God intended us to be altruistic, and therefore gave us an ethical code to shape our behaviour.  Or, it may be that random mutation produced entities that acted altruistically and more of them survived than did others, so the population created expectations and laws to encourage that behaviour, and God to explain and enforce it.  But trying to explore which of those (and many other variant) options might be right only muddies the understanding of what options actually help us form a secure society today.

Schneier has, as with “Beyond Fear” (cf. BKBYNDFR.RVW) and “Secrets and Lies” (cf. BKSECLIE.RVW), not only made a useful addition to the security literature, but created something of value to those involved with public policy, and a fascinating philosophical tome for the general public.  Security professionals can use a number of the models to assess controls in security systems, with a view to what will work, what won’t (and what areas are just too expensive to protect).  Public policy will benefit from examination of which formal structures are likely to have a desired effect.  (As I am finishing this review the debate over SOPA and PIPA is going on: measures unlikely to protect intellectual property in any meaningful way, and guaranteed to have enormous adverse effects.)  And Schneier has brought together a wealth of ideas and research in the fields of trust and society, with his usual clarity and readability.

Forcing your users to write down their passwords

This sums up everything that is wrong with the “password policy” theme. From the t-mobile web site:

T-Mobile Password Policy

There is no way any reasonable person can choose a password that fits this policy AND can be remembered (note how they are telling you that you CANNOT use special characters. So users now have to bend according to the lowest common denominator of their bad back-end database routine and their bad password policy).

I’m sure some high-paid consultant convinced the T-MO CSO that stricter password policy is the answer to all their security problems. Reminds me of a story about an air-force security chief that claimed 25% increase in security by making mandatory password length 10 characters instead of 8, but I digress.

Yes, I know my habitat. No security executive ever got fired for making the user’s experience more difficult. All in the name of security. Except it’s both bad security and bad usability (which, incidentally, correlate more often than not, despite what lazy security ‘experts’ might let you believe.

I’ve ranted about this before.

Chapter one, the introduction, is a review of general identity related issues.  The definition of identity management, in chapter two, is thorough and detailed, covering the broad range of different types and uses of identities, the various loci of control, the identity lifecycle (in depth), and a very effective technical definition of privacy.  (The transactional attribute is perhaps defined too narrowly, as it could relate to non-commercial activities.)
“Fundamental technologies and processes” addresses credentials, PKI (Public Key Infrastructure), single sign-on, Kerberos, privacy, and anonymous systems in chapter three.  The level of detail varies: most of the material is specific with limited examples, while attribute federation is handled quite abstractly.  Chapter four turns to standards and systems, reviewing SAML (Security Assertion Markup Language), Web Services Framework, OpenID, Information Card-Based Identity Management (IC-IDM), interoperability, other prototypes, examples, and projects, with an odd digression into the fundamental confidentiality, integrity, and availability concepts.  Challenges are noted in chapter five, briefly examining usability, access control, privacy, trust management, interoperability (from the human, rather than machine, perspective, particularly expectations, experience, and jargon), and finally biometrics.

This book raises a number of important questions, and mentions many new areas of work and development.  For experienced security professionals needing to move into this area as a new field, it can serve as an introduction to the topics which need to be discussed.  Those looking for assistance with an identity management project will probably need to look elsewhere.

The malware problem looks better after the first cup of coffee

Since most of my income comes from a company on the West Coast, I’m used to people assuming that I should be working according to their time zone (PST) rather than my own (GMT). But apparently we’re all wrong.
According to Trustwave’s Global Security Report:

“The number of executables and viruses sent in the early morning hours increased, eventually hitting a maximum between 8 a.m. and 9 a.m. Eastern Standard Time before tapering off throughout the rest of the day. The spike is likely an attempt to catch people as they check emails at the beginning of the day.”

Did I miss something? Has everyone but me moved to the East Coast? I’m not even sure it matters when you receive a malicious executable, unless you don’t get around to opening it until after your security software has been updated to detect it. However, the report also tells us that:

“The time from compromise to detection in most environments is about six months…”

So if evading AV software is really the point, this seems to suggest that all those people who’ve moved to the East Coast are coping even less effectively with their email than I am.

Hold on, though. Maybe this tells something about the blackhat’s time zone, rather than the victim’s? The report doesn’t seem to tell us anything about the geographical origin of the emails that Trustwave has tracked, but it does tells us that apart from the 32.5% of attacks in general that are of unknown origin, the largest percentage (29.6%) come from the Russian Federation. Russia actually covers no less than nine time zones (until a couple of years ago, it was eleven), but perhaps we can assume for the sake of argument that a high percentage of those attackers are in time zones between CET and Moscow Standard (now UTC+4), which applies to most of European Russia. (That assumption allows us to include Romania and the Ukraine.) Perhaps, after a hard morning administering botnets, Eastern European gangsters are best able to find time to fire off a few malicious emails between the afternoon samovar break and early evening cocktails. Convinced? No, me neither.

Actually, there are some interesting statistics in the report. If they’re reliable, some assumptions that we make about geographical distribution, for example, might bear re-examination. But I’d really have to suggest that journalists in search of something new to say about malware examine some of the report’s interpretations with a little more salt and scepticism. I suppose I should be grateful that no-one has noticed yet that according to the report, twice as many attacks originate in the Netherlands as do in China. Just think of the sub-editorial puns that could inspire…

New computers – Windows 7 – printers and USB

C’mon, fess up.  Who did the discovery protocol for Windows Universal Plug and Play?

Was it supposed to work for USB?

Windows has always been annoying in regard to USB.  I’ve had it “forget” mice and jump drives (sometimes never to accept them again on that port).  I’ve had a port “locked” by an Adobe picture manager (which I hadn’t realized Adobe was installing while I was trying to upgrade Reader to get rid of the latest round of vulnerabilities) so that it never recognized my camera again on *any* USB port, and insisted that every jump drive I attached was a camera.  Windows has never been willing to specifically identify any USB port even if it reports a problem.

Recently our printer (yes, a Winprinter with a USB connection: these days, can you find any other type?) has been flaky.  Not the printer itself: it’s fine.  And, yes, I did install the correct Win 7 driver, thank you very much.  Not that either Microsoft nor HP were very helpful about that.  The computer started out just fine, for a few months.  Then it started not recognizing that it had a printer.  Then it started seeing that it had something connected, but couldn’t tell what it was.  And sometimes it would cycle between these states constantly, while I was working.  (I’d hear a rising double beep as it realized it had a printer, or a falling double beep as it lost it, or couldn’t recognize it.  It got so bad that I’ve had to turn the speaker volume down given the near constant clamour of beeps.)  We tried different things: rebooting, changing to another user, power cycling the printer, power cycling the printer and waiting a while before we turned it on, turning the printer on first, not turning the printer off when once it had successfully accepted a print job.  Sometimes they worked, sometimes they didn’t.  Recently it’s gotten a lot worse.

(And, yes, I did Google it.  And AltaVistaed it  Never found anything helpful.  Even when I added profanity, as I suspected would be the case with someone who had gotten as frustrated with it as I was.)

So, at Gloria’s suggestion, today I hauled the computer out of its nook and swapped the printer to another USB port.

She was right: after I changed it the queue printed.

I lost the keyboard, monitor (twice), mouse (twice).  Eventually got them back. And then the computer crashed.  I lost some bookmarks I had collected this morning, and some outbound email: don’t know what or how much.  As far as I can tell I still have access to other devices, but I got a report that the Passport drive has a problem and I’m currently running a check on it.

But the printer is still printing.  So far.

I could really get to hate Microsoft.  Very easily …

New computers – Kindle – Books (part 2)

A few more places to find books.

Bookyards – unfortunately, these seem to be limited to what you could find on Gutenberg, and they are in PDF.

Mobipocket – at least these are in .mobi format.

Baen – they’ve done a lot of their back catalogue.

Bookmonk – interesting site, graphical links, for those who choose books by cover.

Smashwords – new publications, many free.
