Information security governance in Saudi organizations: an empirical study
Authors: Abu‐Musa Ahmad 
Published: October 2010

PurposeThis paper seeks to empirically examine the existence and implementation of information security governance (ISG) in Saudi organizations.Design/methodology/approachAn empirical survey, using a self‐administered questionnaire, is conducted to explore and evaluate the current status and the main features of ISG in the Saudi environment. The questionnaire is developed based on ISG guidelines for boards of directors and executive management issued by the Information Technology (IT) Governance Institute and other related materials available in the literature. A total of 167 valid questionnaires are collected and processed using the Statistical Package for Social Sciences, version 16.FindingsThe results of the study reveal that although the majority of Saudi organizations recognize the importance of ISG as an integrant factor for the success of IT and corporate governance, most of them have no clear information security strategies or written information security policy statements. The majority of Saudi organizations have no disaster recovery plans to deal with information security incidents and emergencies; information security roles and responsibilities are not clearly defined and communicated. The results also show that alignment between ISG and the organization's overall business strategy is relatively poor and not adequately implemented. The results also show that risk assessment procedures are not adequately and effectively implemented, ISG is not a regular item in the board's agenda, and there are no properly functioning ISG processes or performance‐measuring systems in the majority of Saudi organizations. Accordingly, appropriate actions should be taken to improve implementing and measuring the ISG performance in Saudi organizations.Originality/valueFrom a practical standpoint, managers and practitioners alike stand to gain from the findings of this study. The results of the paper enable them to better understand and evaluate ISG and to champion IT development for business success in Saudi organizations.
A survey of intrusion detection and prevention systems
Authors: Patel Ahmed , Qassim Qais , Wills Christopher 
Published: October 2010

PurposeThe problem of protecting information and data flows has existed from the very first day of information exchange. Various approaches have been devised to protect and transfer such information securely. However, as technology and communications advance and information management systems become more and more powerful and distributed, the problem has taken on new and more complex dimensions and has become a major challenge. The widespread use of wired and wireless communication networks, internet, web applications and computing has increased the gravity of the problem. Organizations are totally dependent on reliable, secure and fault‐tolerant systems, communications, applications and information bases. Unfortunately, serious security and privacy breaches still occur every day, creating an absolute necessity to provide secure and safe information security systems through the use of firewalls, intrusion detection and prevention systems (ID/PSs), encryption, authentication and other hardware and software solutions. This paper aims to address these issues.Design/methodology/approachThis survey presents an up‐to‐date comprehensive state of the art overview of ID/PSs based on risk analysis, a description of what ID/PSs are, the functions they serve, its two primary types and different methods of ID that may employ.FindingsAs security incidents are increasing and are more aggressive, ID/PSs have also become increasingly necessary, they compliment the arsenal of security measures, working in conjunction with other information security tools such as malware filters and firewalls. Because of a growing number of intrusion events and also because the internet and local networks together with user applications have become so ubiquitous, the need arises to use sophisticated advanced techniques from autonomic computing, machine learning, artificial intelligence and data mining to make intelligent/smart ID/PSs.Originality/valueThis paper perceives the requirements of developing a new detection mechanism to detect known and unknown threats, based on intelligent techniques such as machine learning and autonomic computing.

Authors: Patsos Dimitrios , Mitropoulos Sarandis , Douligeris Christos 
Published: October 2010

PurposeThe paper proposes looking at the automation of the incident response (IR) process, through formal, systematic and standardized methods for collection, normalization and correlation of security data (i.e. vulnerability, exploit and intrusion detection information).Design/methodology/approachThe paper proposes the incident response intelligence system (IRIS) that models the context of discovered vulnerabilities, calculates their significance, finds and analyzes potential exploit code and defines the necessary intrusion detection signatures that combat possible attacks, using standardized techniques. It presents the IRIS architecture and operations, as well as the implementation issues.FindingsThe paper presents detailed evaluation results obtained from real‐world application scenarios, including a survey of the users' experience, to highlight IRIS contribution in the area of IR.Originality/valueThe paper introduces the IRIS, a system that provides detailed security information during the entire lifecycle of a security incident, facilitates decision support through the provision of possible attack and response paths, while deciding on the significance and magnitude of an attack with a standardized method.

Emerging technology, innovation, and the digital library
Authors: Cervone H. Frank 
Published: October 2010

PurposeThis paper aims to discuss the issues and impact of emerging technologies and innovation in libraries.Design/methodology/approachThe paper is a general overview of the concepts and application of emerging technologies and innovation to library practices.FindingsLibrarians need to be careful about how terminology such as emerging technology is used as emerging technology in one sector is not new in others and to have credibility, librarians must understand how those differences may play out within their overall organizations. When libraries are situated in parent organizations that value experimentation and innovation, libraries must be willing to experiment and innovate with services and processes. Furthermore, because technology changes quickly, libraries need to be agile in evaluating and implementing technology.Originality/valueThis paper fills a gap in the digital library project management literature by providing an overview of the issues related to implementing and using emerging technology and innovative practices within libraries.

Authors: Creel James S. , Koenig Jack R. (Jay) , McGeachin Robert 
Published: October 2010

PurposeThe purpose of this paper is to describe the transition of a collection in Texas A&M University's institutional repository from single item submission to batch importation as a primary method of ingest. This transition was made possible with assistance and technical work on behalf of the library.Design/methodology/approachThe digital initiatives staff examined the workflow of the collection's manager and submitters. A process was created to produce the necessary data structures for batch import from resources that were already being generated by the collection workflow.FindingsIt was found that batch importing assistance provided by the library improved the collection's growth rate and efficiency without interrupting the workflow of the collection management team.Practical implicationsThis paper demonstrates the benefit of libraries and other institutional repository hosts offering batch‐loading assistance to managers of large repository collections.Originality/valueThis paper should resonate with institutional repository managers and digital services librarians, as many have neglected to offer batch importing or other assistance to users citing a lack of resources.

Authors: Frutchey Jim 
Published: October 2010

PurposeThe aim of this paper is to clearly show the process, cost, and benefits of an audio digitization project within a university library.Design/methodology/approachFrom formulating the idea for a new digital collection available to patrons via the library catalog through implementation, promotion, and gathering feedback, each step is detailed.FindingsAlthough it is a time‐consuming endeavor, the creation of unique digital library collections can produce a variety of benefits for both library patrons and librarians.Originality/valueThe paper is written by a librarian who is neither a computer nor cataloging expert. It is an attempt to show others who may have important but antiquated collections that digitization projects may be successfully completed without advanced technical skills or a large budget.
“Sense of place” in digital collections
Authors: Von Seggern Marilyn , Merrill Alex , Zhu Lihong 
Published: October 2010

PurposeInternet sites about geographical locations attempt to articulate and convey “sense of place”, a concept that relates to the unique identity and meaning attached to place. This paper aims to review the variety of resource types, metadata sources, and navigation features that are used by “sense of place” web sites to communicate with and involve the user. Assessment of place‐based digital collection sites is discussed.Design/methodology/approachCurrent place‐based sites were reviewed to show the diversity and range of content as well as metadata options, applications for users, and web features that make the most of location‐specific foci.FindingsPlace‐based sites present many types of resources and use geospatial, interactive, customization, and other tools to enhance the content, assist the user in finding resources, and develop “sense of place”. Assessment of such digital collections is being done but could be used more extensively to improve the sites.Practical implicationsIdentifying and discussing place‐based digital collections will serve to highlight a specialized type of site and collection. Attention to the enhancement of “sense of place” internet sites could further geographical and geospatial interests, education, and web applications.Social implications“Sense of place” sites provide information about places that have unique history, environmental sensitivity, or special meaning. Digital content is readily available for educational purposes and can be a contribution point for shared history and experience.Originality/valueThis paper will be of value to those interested in digital collections primarily focused on a geographical location and how web applications can build on the content to convey “sense of place” to users of the site.

Authors: Edith Wiria Florencia , Fai Leong Kah , Kai Chua Chee 
Published: October 2010

PurposeTissue engineering (TE) involves biological, medical and engineering expertise and a current engineering challenge is to provide good TE scaffolds. These highly porous 3D scaffolds primarily serve as temporal holding devices for cells that facilitate structural and functional tissue unit formation of the newly transplanted cells. One method used successfully to produce scaffolds is that of rapid prototyping. Selective laser sintering (SLS) is one such versatile method that is able to process many types of polymeric materials and good stability of its products. The purpose of this paper is to present modeling of the heat transfer process, to understand the sintering phenomena that are experienced by powder particles in the SLS powder bed during the sintering process. With the understanding of sintering process obtained through the theoretical modeling, experimental process of biomaterials in SLS could be directed towards the appropriate sintering window, so as not to cause unintentional degradation to the biomaterials.Design/methodology/approachSLS uses a laser as a heat source to sinter parts. A theoretical study based on heat transfer phenomena during SLS process was carried out. The study identified the significant biomaterial and laser beam properties that were critical to the sintering result. The material properties were thermal conductivity, thermal diffusivity, surface reflectivity and absorption coefficient.FindingsThe influential laser beam properties were laser power and scan speed, which were machine parameters that can be controlled by users. The identification of the important parameters has ensured that favorable sintering conditions can be achieved.Research limitations/implicationsThe selection of biopolymer influences the manner in which energy is absorbed by the powder bed during the SLS process. In this paper, the modeling and investigative work was validated by poly(vinyl alcohol) which is a biomaterial that has been used for many biomedical and pharmaceutical purposes.Practical implicationsThe paper can be the foundation for extension to other types of biomaterials including biopolymers, bioceramics and biocomposites.Originality/valueThe formulation of the theory for heat transfer phenomena during the SLS process is of significant value to any studies in using SLS for biomedical applications.
Systematic proposal to calculate price of prototypes manufactured through rapid prototyping an FDM 3D printer in a university lab
Authors: Henrique Pereira Mello Carlos , Calandrin Martins Rafael , Rosa Parra Bruno , de Oliveira Pamplona Edson , Gomes Salgado Eduardo , Tavares Seguso Rodrigo 
Published: October 2010

PurposeThe purpose of this paper is to propose a systematic study to formulate the cost of prototypes manufactured through rapid prototyping (RP) an fused deposition modeling (FDM) 3D printer in a university lab.Design/methodology/approachThe paper has a theoretical‐conceptual approach. This approach is carried out by studying and proposing a methodology for calculating the cost of pieces prototyped an FDM 3D printer.FindingsThis work originated from a gap in literature to establish a way to calculate the price of RP pieces from FDM 3D printers in universities' labs, since no similar work has dealt with this RP technology and has not taken into account the costs of post‐processing step. The results suggest that the formulation may be used to calculate price of prototyped pieces through FDM 3D printer.Research limitations/implicationsThe systematic approach proposed by this research to formulate cost for the RP pieces is initially oriented only to modelling technique by FDM 3D printer. Considerations on operator's and designer's hourly rates are those practiced in Brazil, which may differ from other countries.Originality/valueThe paper's scientific contribution is a specific formulation to calculate price of prototyped pieces through FDM considering the post‐processing way, which differs from previous published works. The formulation implies that the execution times and the amount of material used were obtained by internal calculation of the tested machine. This is different from what has been already studied by previous literature which considers an index that encompasses the machine operation cost in function of time. It is aimed that the results obtained here are accurate, since error margins of the process variables are reduced.
Vessel phantom fabrication using rapid prototyping technique for investigating thermal dosage profile in HIFU surgery
Authors: Jiang Cho‐Pei 
Published: October 2010

PurposeThe purpose of this paper is to propose a method for fabricating tumor vessel phantom and then investigate the thermal dosage profile caused by high‐intensity‐focused ultrasound (HIFU) surgery.Design/methodology/approachIn this paper, a thermal sensitive powder has been added to silicon‐based gel as a vessel phantom raw material for displaying the thermal dosage profile caused by HIFU. A fused deposition modeling system was used for fabricating the shell casting mold and the vessel arbor mold. The arbor prototype, made of wax, was solidified in the cavity of vessel arbor mold. The vessel phantom object embedded with the arbor prototype was created in the shell mold casting process. The vessel phantom was obtained by immersing the vessel phantom object into hot water (65°C) for melting the vessel arbor prototype. A HIFU experiment has been conducted for verifying the feasibility of displaying the thermal dosage profile of the fabricated vessel phantom. The HIFU experimental parameters including the driving power of HIFU transducer, ultrasound exposure duration and volume flow rate were used for investigating the thermal dosage variation by the perfusion of vessel phantom.FindingsThe properties of fabricated mimicking phantom agree well with those of human tissue. The experimental results show that the proposed method can fabricate the Y‐type vessel phantom. The proposed method has been proved as a promising fabrication process in fabricating the vessel phantom and it displays the thermal dosage profile in HIFU experiment.Originality/valueThe proposed method and the developed experimental apparatus are helpful for pre‐clinical HIFU surgery.

Published: October 2010

PurposeThe purpose of this paper is to show how to precisely control the liquid resin coating thickness in stereolithography (SL).Design/methodology/approachA vacuum adsorption coating equipment and technology are developed to precisely control the liquid resin coating thickness in SL. Dual‐electrode device is used, so adsorption can be precisely controlled and the electrode polarization can be avoided.FindingsIt turns out that the apparatus can control coating thickness effectively, and thickness uniformity is increased remarkably, which induces the standard deviation thickness decrease from 0.00547 to 0.00243 mm, and efficiency of rapid prototyping production increase by 53 percent.Originality/valueThe paper demonstrates that the apparatus can control coating thickness effectively.
Design and manufacture of injection mould tool inserts produced using indirect SLS and machining processes
Authors: Ilyas Ismet , Taylor Chris , Dalgarno Kenny , Gosden John 
Published: October 2010

PurposeThe purpose of this paper is to report on the use of a combination of indirect selective laser sintering (SLS) and machining processes to create injection mould tools, an approach designed to offer the capability to create conformal cooling channels in the core/cavity inserts together with the levels of surface finish and accuracy required to meet typical injection mould tool specifications.Design/methodology/approachThe research has been pursued through three industrial case studies. In each study, existing injection mold inserts have been redesigned to give a conformally cooled tool. These have then been manufactured using indirect SLS, high‐speed machining, electro‐discharge machining and polishing. The inserts have been evaluated in industrial trials to assess their performance in terms of cycle time, energy usage, durability and quality. The insights gained from the three case studies have then been developed into a series of design rules, which may be applied in the development of tooling for new applications.FindingsThe results show that significant productivity improvements and energy use reductions in injection moulding are possible through the implementation of conformal cooling, and that the material has sufficient wear resistance to be used in production applications. However, it is recommended that modelling is always used to understand the impact of conformal cooling channels, and manufacture is carefully planned to ensure that the required internal geometry is created.Originality/valueThe paper presents new results on the impact of conformal cooling on the productivity and energy efficiency of injection moulding, and on the durability of the indirect SLS material in injection moulding applications. A novel “cut‐out volume” technique for powder clearing is also presented, along with a set of design rules to support further application of the work.

Authors: Singh A.K. , Srinivasa Prakash Regalla 
Published: October 2010

PurposeThe aim of this paper is to predict the optimum settings of the process parameters for selective laser sintering process.Design/methodology/approachA simulation model is prepared using author written subroutines in ANSYS® Parametric Design Language (APDL™) environment. The simulation model is then run at the experimentally designed points using central composite design approach. Based on the observations, a response surface is generated for the density of a sintered part as a function of various process parameters.FindingsThe results indicate the optimum settings of the process variables to achieve a desired value of the density.Research limitations/implicationsThe developed simulation model can be used to predict the density of the final part with limited part geometries and may not be applicable for the complex shapes or with irregular features.Practical implicationsThe parameter settings as predicted by the simulation model may not be reproduced exactly by the experimental readings.Originality/valueThe results of the simulation study concur with previous investigation by other researchers. Hence, the model can be suitably modified according to available data for different materials (amorphous and crystalline) taking the due considerations.
