Apparently a fellow recently was indicted on charges of hacking into the Republican vice presidential nominee's Yahoo email account, by simply doing some research on the Internet to find her birthday, zip code, and the answer to her security question, "Where did you meet your spouse?" All told the attack reportedly took under an hour to complete.

Given the level of interest in Palin and other public figures, and the large amount of information about them available to the public, it makes sense that they will be some of the easiest targets for attacks like this.

The announcement is of course Good News — because once the PCeU is up and running next Spring, it should plug (to the limited extent that £2 million a year can plug) the “level 2″ eCrime gap that I’ve written about before. viz: that SOCA tackles “serious and organised crime” (level 3), your local police force tackles local villains (level 1), but if criminals operate outside their force’s area — and on the Internet this is more likely than not — yet they don’t meet SOCA’s threshold, then who is there to deal with them?

In particular, the PCeU is envisaged to be the unit that deals with the intelligence packages coming from the City of London Fraud Squad’s new online Fraud Reporting website (once intended to launch in November 2008, now scheduled for Summer 2009).

Of course everyone expects the website to generate more reports of eCrime than could ever be dealt with (even with much more money), so the effectiveness of the PCeU in dealing with eCriminality will depend upon their prioritisation criteria, and how carefully they select the cases they tackle.

Nevertheless, although the news this week shows that the Home Office have finally understood the need to fund more ePolicing, I don’t think that they are thinking about the problem in a sufficiently global context.

A little history lesson might be in order to explain why.

Back in 1930’s, Bonnie and Clyde and other US bank robbers were using the new-fangled automobile to flee across state lines — creating jurisdictional problems as a result. The US solution was to make bank robbery (along with auto-theft and other related offences) into federal offences rather keeping them as state-specific infractions. In particular this meant that the FBI could provide federal level policing (tracking down and killing John Dillinger for example).

We have the same jurisdictional issues dealing with cyberspace, with criminals in one country fleecing consumers in another while using systems hosted in a third. The Convention on Cybercrime addresses part of the problem by trying to ensure international consistency where eLaws are specifically needed (which of course is only the case for small parts of eCriminality, fraud is fraud whether eEnabled or not). However, there is limited inter-jurisdictional co-ordination for eCrime investigations — for example Interpol (often incorrectly perceived to be international police force) merely keeps a large database and passes faxes from one place to another.

In practice, most cross-border investigations are done as “joint operations” and the jointness is usually very limited — one force does all the legwork and a liaison officer in the other country deals with local paperwork. There’s usually a quid pro quo element to these joint operations, for budgeting reasons if no other.

What isn’t happening, or at least only in a handful of very specialised areas, is any international co-operation in setting priorities or selecting cases to pursue. Every country is doing its own thing about eCrime, and there’s a widespread impression that any criminal who can operate from “across the state line” is essentially immune from serious investigation.

We identified this problem last year when we (Ross Anderson, Rainer Böhme, Tyler Moore and myself) wrote a report on Security Economics and the Internal Market for ENISA. It’s not an easy one to fix whilst politicians (and populaces) are unwilling to see “foreign” police officers operating in their country, and the establishment of a truly international “cyber police force” seems equally unlikely.

Our policy proposal to tackle the issue harks back to WWII’s SHAEF, which has morphed into similar arrangements within NATO. In essence liaison officers from multiple forces would sit around a single table, working with a central coordinator, to set policy and decide which investigations to pursue. They would then communicate back to their own countries, who have specifically budgeted to provide appropriate assistance. So it’s very like “joint operations”, but the scheme is multi-laterial, and has a true command and control function in the centre — who will quickly learn to shy away from politically sensitive topics and make a real impact on eCriminality.

To summarise then, a welcome to the Home Office for finally finding a small amount of funding for some country-wide ePolicing; but it’s well past time to be working on world-wide initiatives.

COBIT rivals ITIL from The IT Skeptic

“Everyone is tiptoeing around the fact that COBIT offers a significant competitive body of knowledge (BOK) to ITIL. Sure ITIL goes into more depth in places, but to say COBIT sits over the top is to grossly understate the overlap. COBIT extends a long way down into the “how” and it does it with an intellectual rigour that ITIL lacks.”

Interesting stuff that.  A detailed mapping might help some folks.  Either way, the good news for those keen on understanding risk management is that governance metrics, done right, allow us to understand a part of that “capability to manage risk” we’re always looking for.   Assurance, verification and the acquisition and interpretation of knowledge is king.   Speaking of which….

How To Tell When “Nothing Happens” by Pete Lindstrom

“…problem is that, it isn’t really true that “nothing happens” when you employ some specific security control to prevent an exploit. Not only that, but even when it is difficult to collect data on what didn’t happen, one can devise experiments to tell how frequently that nothing occurred.”

Good analysis is all about the uncertainty.   Speaking of accounting for uncertainty…

Assets Good Until Reached For by Gunnar Peterson

“If you have a 100,000 dekstops or 100,000 servers it hard to manage. You will need to automate and to do that you need to abstract, but you should also realize that its a drawing on a whiteboard not reality. You need abstraction assurance.”

And there’s the trick.  We might call “abstraction assurance” an analog to “confidence” or “uncertainty” in certain priors (metrics) or posteriors (calculated values based on those metrics).  The stronger that abstraction assurance is, the less uncertainty we have in our knowledge and the better our ability to create wisdom from that knowledge (you know, make decisions).

Epstein, Snow and Flake: Three Views of Software Security by Adam Shostack

Adam’s focus is on software security, but the discussion here can be abstracted out into the broader realm of risk management quite nicely.

Two-thirds of firms hit by cybercrime from Security Focus

The US DoJ says that in 2005 (there’s some timely data) 2/3 of their surveyed firms detected at least one cybercrime.  “Cybercrime” is “classified … into cyber attacks, cyber theft, and other incidents.”  Pretty general.  Also from the report:  “Computer viruses made up more than half of all cyber attacks.”

(That sound you hear is me tapping my forehead lightly on large iron object)

Lessons Learned from “Personal” Risk Management By: Christopher Daugherty

“This process is what I call “personal risk management.”  All of us have done it and will continue to do so.  Why is it, then, many companies have ignored following similar principles with the on-going health of the business?  This is a debate with many different answers so I ask you to select the best answer for your employer:

a) Have not ignored as this keeps me awake at night!

b) Please restate the problem, I cannot hear well with my head buried in the sand.

c) We passed our SOX audit so we checked this off the list!

d) We are informed of the challenge but we have a business to run and profits to make

e) Is this what internal audit and risk management has been telling us?”

The panel will discuss fourth-generation (4G) networks, including both LTE and WiMax, and discuss what these networks might deliver, as well as how Wi-Fi networks fit into this future.

One of the organizers asked if I'd solicit questions--you can post them below--which they'll try to ask during the panel. The group would then write up responses which could posted in turn here.

The powerhouse that is Kevin Werbach, a professor at The Wharton School, is moderating the event. Werbach has been part of interesting thinking about spectrum for many years, a former editor of Release 1.0, and a former FCC staffer. He'll share the stage with a fairly high-powered crowd, including AT&T's enterprise architect for mobility, the president of NAC, and senior people from Comcast and Sprint Xohm.

The event is part of the Mid-Atlantic Chapter series called MobileMonday, an interesting business group that's trying to provoke discussion and development around mobile technology and access. This particular event is sponsored by local business development organization Select Greater Philadelphia.

Linksys addressed many of my concerns with that previous device. The 610N can mount a drive and share it via SMB and FTP, have two full-speed connections running over both bands without skipping a beat, and supports several methods of getting the one-click WPS (Wi-Fi Protected Setup) to work. Read the review for all the details, but I can't recommend this router to Mac users with any needs beyond basic networking; I'm perfectly happy to give it a full thumbs-up for Windows XP and Vista users, however.

WPS is a particular mess, by the way. Linksys has four somewhat distinct methods of using WPS to enable a password-free encrypted connection between a client and a base station: a button on the front that, when pressed, turns on WPS; and three modes (one of them similar to that button) accessible via their Web configuration software. One option is to get the base station to create a short PIN that's then entered on the client system as an out-of-band confirmation that there's no man in the middle.

Apple, by contrast, has a single way of joining a WPS-offering base station: it displays the network's name in bold. Select the network, and Mac OS X displays a key code that needs to be entered on the base station. But the WRT610N can't handle that option. If you put the WRT610N into a mode in which Apple can spot the device as offering a WPS handshake, you can't enter the code into the Linksys router!

This shows that there's still rough edges in the WPS protocol that two of the highest-selling makers of Wi-Fi gear can manage to not mesh up their respective options. (Apple declined to comment for my Macworld story; Linksys confirmed the lack of compatibility, but put the burden on Apple's doorstep.)

Solace provides sophisticated middleware functionality in hardware to monitor, filter, route, transform and secure very large volumes of events in real time and with minimal processing overhead.  Solace uses leading-edge FPGA, ASIC and network processor technology to increase throughput and lower latency of event processing. Applications such as fraud detection, algorithmic trading, compliance, insider trade monitoring, risk management and more can be tackled more effectively by separating the simple monitoring, filtering and normalization of raw events from the complex processing of select events. This event pre-processing takes the burden off CEP engines allowing individual engines to be much more effective. 

An interesting blog post this morning discusses the obstacles and implications of this kind of technology, in part quoting a recent New York Times article —

In short, we need a log-on system that relies on cryptography, not mnemonics. As users, we would replace passwords with so-called information cards, icons on our screen that we select with a click to log on to a Web site. The click starts a handshake between machines that relies on hard-to-crack cryptographic code.

An obstacle to this kind of system are the current initiatives toward Open ID and single-sign on services, strategies that are backed by large industry players such as the Equifax, Google, Novell, Microsoft, Oracle, etc. In the open ID system, you would log in to a session on the web with one password, which would be accepted by any application/account supporting the open ID infrastructure.

To me Open ID sounds like a step backwards, toward less security…
then again, I would think that encrypting everything could also make your system run significantly slower, and that it wouldn’t prevent all the risks either…

You will discern a certain amount of enthusiasm for blocking, and for a “something must be done” approach. However, in coming to their conclusions, they do not, in my view, seem to have listened too hard to the evidence, or sought out expertise elsewhere in the world…

Google/YouTube told them that 10 hours of video was posted every minute, and the amount is increasing. In the oral evidence session an MP helpfully suggested: “That video content is tagged. You do not need to look at every single minute of video content. Surely you could have people who would look at the video content which is tagged with labels which suggest it could be inappropriate.” Of course “happy_slapping.wmv” or “fluffy_bunnies.avi” must always contain exactly what it says on the tin (not!) but unaccountably Google said it was a “fair suggestion”, so perhaps my cynicism is misplaced.

However, back to blocking.

I submitted some evidence of my own, which the committee summarised, reasonably accurately:

Dr Richard Clayton, a researcher in the Security Group of the Computer Laboratory at Cambridge University and author of several academic papers on methods for blocking access to Internet content, pointed out that there was no single blocking method which was both inexpensive and discerning enough to block access to only one part of a large website (such as FaceBook). In his view, the fatal flaw of all network-level blocking schemes was the ease with which they could be overcome, either by encrypting content or by the use of proxy services hosted outside the UK.

The committee’s conclusion, having read this was:

At a time of rapid technological change, it is difficult to judge whether blocking access to Internet content at network level by Internet service providers is likely to become ineffective in the near future. However, this is not a reason for not doing so while it is still effective for the overwhelming majority of users.

which I suppose logically means that the committee thinks that blocking should now be discarded as a policy option — but somehow I think that isn’t their intended meaning.

The Committee should perhaps have a look at this Australian report, which found that ISP level content filtering (and in Australia the politicians want to use ISP level filtering to provide a child-friendly Internet) did work (up to a point) at Tier 3 (the smallest) ISPs. The up-to-a-point is that unlike previous tests the systems didn’t completely wreck the browsing experience by slowing it down. However, the systems blocked only 85-98% of illegal material and similar percentages of material suitable for adults but not for younger children. Interestingly some products were better at different categories.

Getting that many sites wrong is really quite significant, so it’s difficult to see this as a ringing endorsement for blocking the web. Additionally, the Australian report found that the blocking was useless on “non-web” protocols (such as peer-to-peer) and their report specifically didn’t consider cost, or ease of circumvention — so it’s not just UK politicians not wanting to consider evidence on that topic!

Finally, I should note that the Culture Media and Sport Committee has also ignored some rather more recent academic work. The MPs have put into their report that they were horrified to discover that child sexual abuse images took 24 hours to remove in the UK. What (should they ever learn of it) will they make of the recent discovery by Tyler Moore and myself that shows that if the website is hosted abroad then a month is more to be expected?
