Security Risk Management In The Asia Pacific Region: What Are Security Professional Using?, David J. Brooks, Hamish Cotton

Australian Security and Intelligence Conference

The Asia Pacific (APAC) region encompasses a heterogeneous group of nation-states. Like the APAC region, the security industry operates within a diverse and multi-disciplined knowledge base, with risk management being a fundamental knowledge domain within security. Nevertheless, there has been limited understanding of what security professionals use when applying security risk management. The study was designed to gain a better understanding of risk management practice in place throughout APAC. Questions were generated to gauge an understanding of current practice and levels of implementation of standards and frameworks. Participants were drawn from many industries, using non-probabilistic sampling methods in a “snowball” …

Insecurity By Obscurity Continues: Are Adsl Router Manuals Putting End-Users At Risk, Kim Andersson, Patryk Szewczyk Jan 2011

Insecurity By Obscurity Continues: Are Adsl Router Manuals Putting End-Users At Risk, Kim Andersson, Patryk Szewczyk

Australian Information Security Management Conference

The quantity and sophistication of threats targeting ADSL routers is on a steady increase. There is a reliance on end-users to ensure that their ADSL router is secure by continually updating the firmware, using strong authentication credentials, and enabling the in-built firewall. However, to do this, the end-user must be presented with well written procedural instructions, and an explanation of why this is important. This paper examines the design quality and security content provided by vendors in ADSL router manuals. This paper reveals that the lack of security related content and poor overall design could impact on end-users’ interpretation and …

Relationships play a key role in Semantic Web to connect the dots between entities (concepts or instances in a way that enables to absorb the real sense of the entities. Even though relationships are important, it is difficult to categorize or identify them because they consist of complex knowledge in the schema. Therefore systematically identifying relationships yield many advantages and open doors for new research avenues. In this work, we try to identify a specific type of relationship (part of) in a multi-domain dataset and devised an algorithm using Wikipedia to identify patterns of part of relationships in the dataset. …

Cloudvista: Visual Cluster Exploration For Extreme Scale Data In The Could, Keke Chen, Huiqi Xi, Fengguang Tian, Shumin Guo

Kno.e.sis Publications

The problem of efficient and high-quality clustering of extreme scale datasets with complex clustering structures continues to be one of the most challenging data analysis problems. An innovate use of data cloud would provide unique opportunity to address this challenge. In this paper, we propose the CloudVista framework to address (1) the problems caused by using sampling in the existing approaches and (2) the problems with the latency caused by cloud-side processing on interactive cluster visualization. The CloudVista framework aims to explore the entire large data stored in the cloud with the help of the data structure visual frame and …

Flipping The Winner Of A Poset Game, Adam O. Kalinich '12 Jan 2011

Flipping The Winner Of A Poset Game, Adam O. Kalinich '12

Student Publications & Research

Partially-ordered set games, also called poset games, are a class of two-player combinatorial games. The playing field consists of a set of elements, some of which are greater than other elements. Two players take turns removing an element and all elements greater than it, and whoever takes the last element wins. Examples of poset games include Nim and Chomp. We investigate the complexity of computing which player of a poset game has a winning strategy. We give an inductive procedure that modifies poset games to change the nim-value which informally captures the winning strategies in the game. For a generic …

An Approach To Point Based Approximate Color Bleeding With Volumes, Christopher J. Gibson, Zoë J. Wood Jan 2011

An Approach To Point Based Approximate Color Bleeding With Volumes, Christopher J. Gibson, Zoë J. Wood

Computer Science and Software Engineering

Achieving realistic or believable global illumination in scenes with participating media is expensive. Light interacts with the particles of a volume, creating complex radiance patterns. This paper introduces an explicit extension to the commonly used point-based color bleeding technique which allows fast, believable in- and out-scattering effects building on existing data structures and paradigms. The proposed method achieves results comparable to that of existing Monte Carlo integration methods, that is realistic looking renders of scenes which include volume data elements, obtaining render speeds between 10 and 36 times faster while keeping memory overhead under 5%.

Towards Evaluating The Quality Of A Spreadsheet: The Case Of The Analytical Spreadsheet Model, Thomas A. Grossman Jr., Vijay Mehrotra, J Sander Jan 2011

Towards Evaluating The Quality Of A Spreadsheet: The Case Of The Analytical Spreadsheet Model, Thomas A. Grossman Jr., Vijay Mehrotra, J Sander

Business Analytics and Information Systems

We consider the challenge of creating guidelines to evaluate the quality of a spreadsheet model. We suggest four principles. First, state the domain—the spreadsheets to which the guidelines apply. Second, distinguish between the process by which a spreadsheet is constructed from the resulting spreadsheet artifact. Third, guidelines should be written in terms of the artifact, independent of the process. Fourth, the meaning of “quality” must be defined. We illustrate these principles with an example. We define the domain of “analytical spreadsheet models”, which are used in business, finance, engineering, and science. We propose for discussion a framework and terminology for …

A3p: Adaptive Policy Prediction For Shared Images Over Popular Content Sharing Sites, Anna Squicciarini, Smitha Sundareswaran, Dan Lin, Josh Wede

Computer Science Faculty Research & Creative Works

More and more people go online today and share their personal images using popular web services like Picasa. While enjoying the convenience brought by advanced technology, people also become aware of the privacy issues of data being shared. Recent studies have highlighted that people expect more tools to allow them to regain control over their privacy. in this work, we propose an Adaptive Privacy Policy Prediction (A3P) system to help users compose privacy settings for their images. in particular, we examine the role of image content and metadata as possible indicators of users' privacy preferences. We propose a two-level image …

Privacy-Preserving Updates To Anonymous And Confidential Databases, Alberto Trombetta, Wei Jiang, Elisa Bertino, Lorenzo Bossi Jan 2011

Privacy-Preserving Updates To Anonymous And Confidential Databases, Alberto Trombetta, Wei Jiang, Elisa Bertino, Lorenzo Bossi

Computer Science Faculty Research & Creative Works

Suppose Alice owns a k-anonymous database and needs to determine whether her database, when inserted with a tuple owned by Bob, is still k-anonymous. Also, suppose that access to the database is strictly controlled, because for example data are used for certain experiments that need to be maintained confidential. Clearly, allowing Alice to directly read the contents of the tuple breaks the privacy of Bob (e.g., a patient's medical record); on the other hand, the confidentiality of the database managed by Alice is violated once Bob has access to the contents of the database. Thus, the problem is to check …

A Moving-Object Index For Efficient Query Processing With Peer-Wise Location Privacy, Dan Lin, Christian S. Jensen, Rui Zhang, Lu Xiao, Jiaheng Lu Jan 2011

A Moving-Object Index For Efficient Query Processing With Peer-Wise Location Privacy, Dan Lin, Christian S. Jensen, Rui Zhang, Lu Xiao, Jiaheng Lu

Computer Science Faculty Research & Creative Works

With the growing use of location-Based services, location privacy attracts increasing attention from users, industry, and the research community. While considerable effort has been devoted to inventing techniques that prevent service providers from knowing a user's exact location, relatively little attention has been paid to enabling so-called peer-wise privacy-the protection of a user's location from unauthorized peer users. This paper identifies an important efficiency problem in existing peer-privacy approaches that simply apply a filtering step to identify users that are located in a query range, but that do not want to disclose their location to the querying peer. to solve …

Analysis On Partial Relationship In Lod, Kalpa Gunaratna, Sarasi Lalithsena, Cory Andrew Henson, Prateek Jain

Kno.e.sis Publications

Relationships play a key role in Semantic Web to connect the dots between entities (concepts or instances) in a way that enables to absorb the real sense of the entities. Some interesting relationships would give proof for the existence of subject and object in triples which in tern can be defined as evidential relationships. Identifying evidential relationships will yield solutions to some existing inference problems and open doors for new applications and research. Part_of relationships are identified as a special kind of an evidential relationship out of membership, causality and etc. Linked Open data as a global data space would …

Contextual Ontology Alignment Of Lod With An Upper Ontology: A Case Study With Proton, Prateek Jain, Peter Z. Yeh, Kunal Verma, Reymonrod G. Vasquez, Mariana Darnorva, Pascal Hitzler, Amit P. Sheth Jan 2011

Contextual Ontology Alignment Of Lod With An Upper Ontology: A Case Study With Proton, Prateek Jain, Peter Z. Yeh, Kunal Verma, Reymonrod G. Vasquez, Mariana Darnorva, Pascal Hitzler, Amit P. Sheth

Kno.e.sis Publications

The Linked Open Data (LOD) is a major milestone towards realizing the Semantic Web vision, and can enable applications such as robust Question Answering (QA) systems that can answer queries requiring multiple, disparate information sources. However, realizing these applications requires relationships at both the schema and instance level, but currently the LOD only provides relationships for the latter. To address this limitation, we present a solution for automatically finding schema-level links between two LOD ontologies – in the sense of ontology alignment. Our solution, called BLOOMS+, extends our previous solution (i.e. BLOOMS) in two significant ways. BLOOMS+ 1) uses a …

Reconciling Owl And Rules, David Carral Martinez, Adila A. Krisnadhi, Frederick Maier, Kunal Sengupta, Pascal Hitzler Jan 2011

Reconciling Owl And Rules, David Carral Martinez, Adila A. Krisnadhi, Frederick Maier, Kunal Sengupta, Pascal Hitzler

Computer Science and Engineering Faculty Publications

We report on a recent advance in integrating Rules and OWL. We discuss a recent proposal, known as nominal schemas, which realizes a seamless integration of Datalog rules into the description logic SROIQ which underlies OWL 2 DL. We present extensions of the standardized OWL syntaxes to incorporate nominal schemas, reasoning algorithms, and a first naive implementation. And we argue why this approach goes a long way towards overcoming the present paradigm split.

Performance Modeling Of Distributed Collaboration Services, Toqeer A. Israr, Gregor V. Bochmann Jan 2011

Performance Modeling Of Distributed Collaboration Services, Toqeer A. Israr, Gregor V. Bochmann

Faculty Research & Creative Activity

This paper deals with performance modeling of distributed applications, service compositions and workflow systems. From the functional perspective, the distributed application is modeled as a collaboration involving several roles, and its behavior is defined in terms of a composition from several sub-collaborations using the standard sequencing operators found in UML Activity Diagrams and similar formalisms. For the performance perspective, each collaboration is characterized by a certain number of independent input events and dependent output events, and the performance of the collaboration is defined by the minimum delays that apply for a given output event in respect to each input event …
