Foucault’s pendulum is sent crashing to Earth

Category: (i)realidadJoaquim Anguas @ 8:58 pm

If there were ever any truth in the esoteric tales of Umberto Eco’s bestselling novel Foucault’s Pendulum, it seems that the key to that knowledge has been lost.

The original pendulum, which was used by French scientist Leon Foucault to demonstrate the rotation of the Earth and which forms an integral part of Eco’s novel’s labyrinthine plot, has been irreparably damaged in an accident in Paris.

The pendulum’s cable snapped last month and its sphere crashed to the marble floor of the Musee des Arts et Metiers.”

The era of platter-free enterprises

Category: (i)realidad,01,SystemsJoaquim Anguas @ 6:05 pm

We’ve been covering the progression of SandForce for over a year now, creator of smart SSD processors that extend the life of flash storage by better spreading writes across them, boosting performance and reliability along the way. This, according to the company, makes them reliable enough for enterprise use, and IBM has added its vote of support, configuring a 9189 Power 780 server with 56 177GB SSDs (10.5TB in all) sitting behind SandForce’s SF-1500 processor. That combination, when running the TPC-C benchmark, delivered a performance of 150,000 transactions per minute per CPU core. That’s 50 percent higher (per-core) than other entries in the TPC-C benchmark — and considerably cheaper, too. IBM’s configuration is set to be available around October of this year, perhaps ushering in a new era of the platter-free enterprise.”

Path to mediocrity

Category: (i)realidadJoaquim Anguas @ 10:21 am

When President Obama recently released his budget for NASA, he proposed a slight increase in total funding, substantial research and technology development, an extension of the International Space Station operation until 2020, long range planning for a new but undefined heavy lift rocket and significant funding for the development of commercial access to low earth orbit.

Although some of these proposals have merit,  the accompanying decision to cancel the Constellation program, its Ares 1 and Ares V rockets, and the Orion spacecraft, is devastating.”

Open letter to president Obama.

Tracing VoIP calls

Category: (i)realidad,Informática LegalJoaquim Anguas @ 1:39 pm

It was like something out of a movie: an US Capitol Police Special Agent and three San Francisco cops drop by a suspect’s home to ask about threatening phone calls targeting House Speaker Nancy Pelosi. They know the calls all came from a specific phone number, one assigned to the VoIP provider magicJack, but the suspect denies that the number is his. The agent steps into the other room and uses his cell phone to call the number. A telephone connected to the suspect’s computer starts to ring, and the suspect answers it. “Hello,” says the agent.

When the agent returns to the room and asks if the suspect wants to change his story, the man admits that the calls were his own.

The moral of the story: if you’re going to call people and taunt them with the untraceability of your phone number… make sure the phone number is actually untraceable.

Certifying lies

Category: (i)realidad,Informática LegalJoaquim Anguas @ 7:54 pm

Packet Forensics is a firm that provides products and services to enterprises, network operators, law enforcement and defense and intelligence agencies.

It was mostly unknown, but lately it is gaining some focus because of a product of them that may be circumventing SSL.

See Wired (or Gizmodo) and arstechnica for more information. This paper from Christopher Soghoian and Sid Stamm explains the techniques they may be using.

P.S: Do not waste your time searching for the product on their website, it is not listed there.

Evidence of obstruction

Category: (i)realidad,Informática LegalJoaquim Anguas @ 12:24 pm

To the extent that the key players can be identified early, forensically imaging their hard drives immediately will demonstrate good faith and potentially avoid second-guessing later in the investigation.”

Karen E. Willenken, counsel specializing in white-collar criminal defense at New York-based Skadden, Arps, Slate, Meagher & Flom, makes a good point in this very interesting article.

It is focused on the importance of preserving hard drives in order to provide a strong proof support in the event of a request to produce evidence. At least in case the evidence found on them does not make you appear guilty.

Of course it does not fully apply to our legal system (Spain), but there are also mechanisms here that allow the judge to consider bad faith or to draw adverse inference from evidence (or the lack of it).

SecureCloud 2010: day 2 and conclusion

Category: (i)realidad,Informática Legal,SystemsJoaquim Anguas @ 7:38 pm

SecureCloud 2010, second day:

Keynote

First session was an excellent keynote by Mrs. Pamela Jones Harbour, Commissioner at US Federal Trade Commission. She “asked the tough questions” and pointed to some “storm clouds”.

First “storm cloud” she talked about was asymmetry between users and companies: consumers may not understand when they are using cloud computing and it is hard for them to delimitate what data they are willing to share. In the offer side, providers do not offer consumers minimum choices, they present “incomprehensive privacy clauses”, they don’t “adequately disclose the scope” and hide behind “click wrapped agreements”.

Second “storm cloud” was (in)security. Cloud services are potentially unsecure and there’s a potential opportunity for providers to avoid responsibility and accountability.

Third “storm cloud” was competition. There’s a great range of choices and if the consumer’s side does not request accurate information and an adequate level of security in the competitive process, government may have to make an intervention on the market. Turbulent times are forcing companies to low cost, so they are forced by the market to lower best practices.

Fourth “storm cloud” was Incompatible jurisdiction. There is an uncertain state of the law in the USA and there’s being some lobbying at federal legislation on cloud computing. There’s a need to identify challenges and develop good practices. In any case, rules have to be process oriented, not technology oriented, not specific on technology requirements.

Final message was: ask the tough questions but don’t fear the challenge of the cloud.

Semantic Levels and Computer Evidence

Category: (i)realidad,Computing, Signs and Reasoning,Informática LegalJoaquim Anguas @ 10:03 pm

Semantic Levels

As I had explained here, I consider there is a meaning construction, from magnetic fields in the surface of a disk to high level facts we can map to real world, when we talk about computer evidence. This contruction occurs in steps and every step involves a semiosis, up to high level facts.

It is in this last level in which a judge can render them into the final award applying all the arguments presented by the parties and regulations that rule the process.

There’s a state of opinion that defends that computer evidence that has been blessed by digital signature can slip into the process without the intervention of an expert witness: it can be treated as a document.

Don’t get me wrong, I am not saying that computer documents do not deserve this. But I am not talking about word processor or PDF files here, documents that have a meaning by themselves into the procedure. We are talking about something like a log file. And in general, I consider a log file a computer evidence, not a document.

In my oppinion this may lead to the following problem:

SecureCloud 2010: day 1

Category: (i)realidad,Informática Legal,SystemsJoaquim Anguas @ 11:36 pm

Today I attended the first day at SecureCloud 2010, a two days event organized by ISACA, ENISA, CSA and IEEE centered on security on “The Cloud”.

In this first day I had the opportunity to attend to nine talks, all of them very focused and well presented.

Here’s a very concise summary of the sessions:
