IBM’s Watson Goes Cybersecurity
IBM Security has announced a new year-long research project through which it will partner with eight universities to help train its Watson artificial intelligence system to tackle cybercrime.
Knowledge about threats is often hidden in unstructured sources such as blogs, research reports and documentation, said Kevin Skapinetz, director of strategy for IBM Security.
“Let’s say tomorrow there’s an article about a new type of malware, then a bunch of follow-up blogs,” Skapinetz explained. “Essentially what we’re doing is training Watson not just to understand that those documents exist, but to add context and make connections between them.”
Over the past year, IBM Security’s own experts have been working to teach Watson the “language of cybersecurity,” he said. That’s been accomplished largely by feeding it thousands of documents annotated to help the system understand what a threat is, what it does and what indicators are related, for example.
“You go through the process of annotating documents not just for nouns and verbs, but also what it all means together,” Skapinetz said. “Then Watson can start making associations.”
Now IBM aims to accelerate the training process. This fall, it will begin working with students at universities including California State Polytechnic University at Pomona, Penn State, MIT, New York University and the University of Maryland at Baltimore County along with Canada’s universities of New Brunswick, Ottawa and Waterloo.
Over the course of a year, the program aims to feed up to 15,000 new documents into Watson every month, including threat intelligence reports, cybercrime strategies, threat databases and materials from IBM’s own X-Force research library. X-Force represents 20 years of security research, including details on 8 million spam and phishing attacks and more than 100,000 documented vulnerabilities.
Watson’s natural language processing capabilities will help it make sense of those reams of unstructured data. Its data-mining techniques will help detect outliers, and its graphical presentation tools will help find connections among related data points in different documents, IBM said.
Ultimately, the result will be a cloud service called Watson for Cyber Security that’s designed to provide insights into emerging threats as well as recommendations on how to stop them.

AT&T’s iPhone 4 Beats Verizon’s

Comments Off on AT&T’s iPhone 4 Beats Verizon’s
In the phone wars between the two big carriers, it looks like AT&T wins this round. The iPhone 4 on AT&T’s network downloaded data twice as fast, on average, as the iPhone on Verizon Wireless, according to thousands of recent field tests in five U.S. cities performed by Metrico Wireless, an independent mobile device performance evaluation firm.
Metrico’s tests looked at several other variables, however, and found the average Web page load time was nearly the same on iPhone 4 on both networks, a Metrico official said.
Also, when the iPhone 4 was in a moving vehicle, the AT&T model successfully finished about 10% more download session than Verizon’s. But when the iPhones were stationary, the Verizon iPhone had a 10% better success rate in uploading data than the AT&T iPhone, Metrico said.
Metrico did not reveal actual time measurements for any of its results, including the data downloads and uploads or Web page loading times, prior to publication of its full study.
Some of Metrico’s findings are at odds with several smaller spot reports conducted last month that found Verizon’s iPhone performed better on several criteria. But a Metrico official noted that those quick studies were based on only a handful of test samples, often in a single city, including San Francisco, where AT&T’s coverage for the iPhone has been consistently criticized.
AT&T admitted more than a year ago that it had network problems in downtown San Francisco and Manhattan and had begun infrastructure updates. Read More….
