  2. In other news at Columbia U... on Japan Will Stage Mock Cyberattacks · · Score: 1

    On September 22, Bruce E. Bernstein, President of the New York Software Industry Association (NYSIA), testified in writing to the U.S. Senate Committee on Banking, Housing and Urban Affairs during a Hearing on "Examining the Financial Services Industry's Responsibilities and Role in Preventing Identity Theft and Protecting Sensitive Financial Information", mentioning Prof. Malkin project analyzing the security configuration of TLS-protected servers.

    Part of the testimony read:

    "The most pertinent is a project undertaken by Dr. Tal Malkin and her team in the Computer Science Department at Columbia University, in partnership with researchers from IBM, related to the cryptographic security of Internet servers. Cryptography is an essential component of modern electronic commerce. With the explosion of transactions being conducted over the Internet, ensuring the security of data transfer is critically important. Considerable amounts of money are being exchanged over the Internet, either through shopping sites (e.g. Amazon, Buy.com), auction sites (eBay), online banking (Citibank, Chase), stock trading (Schwab), and even the government (irs.gov).

    Dr. Malkin and her team made a systematic study of the cryptographic strength of thousands of "secure" servers on the Internet. Servers are computers that "host" the main functions of the Internet, such as Web sites (Web servers), email (mail servers), and other functions. Communication with these sites is secured by a protocol known as the Secure Sockets Layer (SSL) or its variant, Transport Layer Security (TLS). These protocols provide authentication, privacy, and integrity. A key component of the security of SSL/TLS is the cryptographic strength of the underlying algorithms used by the protocol. Dr. Malkin's study probed 25,000 secure Web servers to determine if SSL was being properly configured and whether it was employed in the most secure way. Improper configuration can lead to attacks on servers, stolen data identity theft, break-ins, etc. Dr. Malkin's project is the most extensive study of actually existing server security on the Internet.

    The team's findings, relevant to these hearings, included some serious weaknesses in how Web servers, including eCommerce servers employed by financial service companies, are currently being configured.

    The most prevalent is that an old, outdated version of SSL, known as SSL 2.0, is still being supported on over 93% of these "secure" servers. SSL 2.0 has many flaws, including a vulnerability to "man in the middle" attacks, which are commonly used for identity theft. While most of these servers also employ a more advanced version of SSL, the incoming communication can choose to use Version 2.0 and thus breach the defenses of the server.

    Another serious problem is the use of 512 bit "public keys" (1,024 bits are recommended), which can be broken readily, thus compromising all of the data on the server using this key length. Over 5% of the "secure" servers are using this key length.

    These security shortcomings are quite serious, and pose risks both to the consumers and the providers in the financial services industry. Financial server security can be increased both by popularizing the correct configurations and, possibly, by greater government oversight in this area.

  3. Re:No its not (its already here) on C|Net Integrates Ontology Viewer Into News Site · · Score: 3, Insightful
    The semantic web expects everyone to agree on one ontological framework (one master ontology)

    WRONG ! Semantic Web expects minimal agreement within communities and domains, for example all camera companies agree on a 'camera ontology' and TV companies create a 'TV ontology', such domain specific ontologies may or may not be linked to a 'master ontology'.
    SW is very much out there.. and is already weaved in to the Web of today..

    - ALL the PDFs and Adobe documents that you use have RDF embedded in them - ALL social networking sites data is marked up using the FOAF ontology

    Well again these may sound just 'specifications' and less of an 'ontology'.. then look in to the rapidly growing billion dollar industry.. bio-chem-pharmaco informatics.. ontologies are becoming backbone of their entire computing, data collection and analysis infrastructure..

    - There is BioPAX for pathway data
    - Gene Ontology is now ported into RDFS/OWL

    Whats more..
    Flip through last month's Nature Biotech and you ll find articles talking about ontologies, RDF & Semantic Web.. Yes, its already here
    Remember, these Biologist are those people who finished the Genome project 2-3yrs earlier than it was orignally planned.. They are very good at collaboration, strong proponents of open-source and very hard workers.. Semantic Web is the right platform for them that gives them tools and a standard to share data seamlessly.. Lets just wait and watch what these people do with it...

    AND...yes there's more.. 5 days ago NIH approved a 20million grant to group at Stanford to create a NATIONAL CENTER for BIOMEDICAL ONTOLOGY. Its the same group which developed the only OWL editor (Protege) available out there !
    I just hope that those guys at NIH are not fools to give away hard earned tax payers money on something thats not gonna work

  5. Re:NASA has needed Google technology for a long ti on Google And NASA To Collaborate On Technology · · Score: 2, Insightful

    Well, you have gotta understand that Google and NASA work on entirely different types of data:

    Google = Web pages/multi-media content that is hyperlinked
    NASA = Large relational tables storing petabytes of data from sensors and telescopic readings...

    The techniques for mining are different in both cases.. when they talk about "Bio/Nano" it refers to entirely new domain.. Its not as easy as plug-n-play with different domains. Agreed, Google has mastered the algorithms for ranking and extracting data from Web-pages but mining data out of relational streams of data is entirely a different ball game.

  9. Java in Research Applications on James Gosling on Java · · Score: 2, Interesting

    Java is very important in the research community. I have been a grad student for past 3-4-5 yrs (..have lost count by now :) but I have never used any language other than Java for my projects/experiments . Be it simulation requiring a Knowledgebase of million RDF triples or be it a Medical Imaging Software to be used by Physicians.. it does it all.

    Somehow 'application researchers' like me are fascinated by the extent of its use.. (drawing nice GUIs or plotting graph with existing Jars)

    With regards to question of scaling..lately companies like IBM have been working towards creating optimized JIT compilers for Java.. I had benchmarked one during my internship at IBM Research.. and it gave nearly similar performance to native C/C++ apps.

  10. Re:Qualify as Semantic Web ? on Using the Semantic Web to Enhance Search · · Score: 1

    SW 2003 Challenge was in October, W3C-OWL standard wasnt yet finalized (It was a Recommendation Standard in Aug 2003, http://www.w3.org/2001/sw/WebOnt/#L151) and to my knowledge no reasoner (Fact/Racer) supported full OWL/DAML+OIL reasoning. So I guess the 'semantics' aspect was not a big concern then..

    Today OWL is formalized. Several OWL based api/reasoners are in place. Using such 'RDF only' applications misguides people and the community. My only request to you all Semantic Web Gurus is to preach right message and best practices :)

  11. Qualify as Semantic Web ? on Using the Semantic Web to Enhance Search · · Score: 1

    The most basic aspect for any application to qualify as a "Semantic Web" app (from SW challenge, http://www-agki.tzi.de/swc/swapplication.html) is that the application should use "some formal description of the meaning of the data" ! RDF by itself doesnt give any *meaning* or *semantics* to the data. You need to associate your RDF data to RDFS/OWL for that purpose (TAP doesnt have a published OWL ontology http://tap.stanford.edu/tap/tapkb.html)

    Also given that you dont have any 'meaning' to nodes and links in your RDF, I presume your searching again boils to 'keyword' based searching ! People find it cool to term their search as "Semantic Search" but I find it difficult to see any 'semantics' in the current application.

  12. DARPA understands Science... on Pentagon to Significantly Cut CS Research · · Score: 1

    Computer Science is just another science like Maths and Physics. In Science, researchers try to discover *generalizations* and *laws* that are like *ultimate truth* by means of experimentation and validation. Maths and Physics have discovered those *laws* and hence people are now more interested in applying them to different fields e.g. biophysics, nanotech etc. similary basic research in CS has peaked the moores law and hence researchers need to focus more on the applications like Bioinformatics, GIS etc Darpa has made a timely move to focus more on application of the technology rather than invest further on basic science which infact is the job of NSF like agencies.
