Application-based anomaly intrusion detection with dynamic information flow analysis
No full textThis paper presents a new approach to detecting software security failures, whose primary goal is facilitating identification and repair of security vulnerabilities rather than permitting online response to attacks. The approach is based on online capture of executions and offline execution replay, profiling, and analysis. It employs fine-grained dynamic information flow analysis in conjunction with anomaly detection. This approach, which we call information flow anomaly detection, is capable of detecting a variety of security failures, including both ones that involve violations of confidentiality or integrity requirements and ones that do not. A prototype tool called DynFlow implementing the approach has been developed for use with Java byte code programs. To illustrate the potential of the approach, it is applied to detect security failures of four open source systems. Also, its effectiveness is compared to the effectiveness of an approach to anomaly detection that is based on analyzing method call stacks. © 2008 Elsevier Ltd.

20 x 20 : Twenty Years of Conundrum Press
No full text"To celebrate twenty years in operation he [Andy Brown] asked one author or artist for each year of the press who had a book out that year to contribute something new, something that represented Conundrum. For some it would have been the first book he or she had ever made. So in the end twenty Conundrumites represent twenty years, hence 20×20. There will be digging deep into the archives, there will be memoirs, there will be comics, drawings, and photographs. There will be laughter and tears of joy." -- Publisher's website

An empirical study of test case filtering techniques based on exercising information flows
No full textSome software defects trigger failures only when certain local or nonlocal program interactions occur. Such interactions are modeled by the closely related concepts of information flows, program dependences, and program slices. The latter concepts underlie a 78variety of proposed test data adequacy criteria, and they form a potentially important basis for filtering existing test cases. We report the results of an empirical study of several test case filtering techniques that are based on exercising information flows. Both coverage-based and profile-distribution-based filtering techniques are considered. They are compared to filtering techniques based on exercising simpler program elements, such as basic blocks, branches, function calls, and call pairs, with respect to their effectiveness for revealing defects. © 2007 IEEE.Agrawal H., 1993, Proceedings.

The Andy Stories
No full textThe four stories within, "Jim of India," "Shooting the Breeze," "Bridge," and "Point Reyes," are part of a longer work in progress, tentatively titled The Andy Stories. The stories follow Andy, a woman in her 50s, on a voyage across the continent and into herself. Of these, all are written in the present, except "Bridge," which is a memory of a visit to San Francisco when Andy was 12. Eventually, some of the Andy stories may stand on their own, though they were originally written in that wavery ground between short story and novel chapter. However, whether story collection or novel, the author intends this thesis to represent early drafts of what may eventually be a longer, and perhaps much different work
The Shape of Things That Came
No full textHG Wells' future history novel looks back from the year 2106. Halfway through the novel's time span, Sean Street explores what the author got almost right - or terribly wrong.
In 1933, Wells published a novel which purported to be a history of the years 1929 to 2105, received from the future in dreams. He called his book The Shape of Things to Come, a phrase that has since become a part of the English language. Now, 84 years into the time scale of this prophetic book and with 88 more to go to complete the story - poet and professor of radio Sean Street goes back to the text and explores what Wells got right, what he got wrong - and what may be yet to come.
From predicting another world war to a utopian world government, he navigates a journey through Wells' future past using audio archives and contemporary news bulletins, with expert help from Christopher Frayling, Andy Sawyer and Orson Wells.
