Increasing the Efficiency of IT Audit Methodology by Using the Organizations Tolerance to IT Systems Availability

The purpose of this paper is to present a method of identifying key risks during IT audit of an organization, regardless of the organization activity, and presenting the impact of the risks identified on the audit methodology. Our main focus is reducing the risk identification during phase during an audit mission. Due to the fast changing economy, the need for efficiency in resources allocation is greater than ever. Optimal use of predefined risk matrix proves to be the main element contributing to an increase in efficiency.Audit, Risk Assessment, Audit Areas, Residual Aggregated Risk

IMPROVING PERCEPTUAL DIMENSION OF KNOWLEDGE QUALITY BY AUDIT TECHNIQUES

This paper present the problems linked to the knowledge quality concept, taking into account the logical, the structural and the perceptual dimensions of knowledge quality. The logical dimension is based on data and software applications quality and can be improved by technical and computerized environment control audit. The structural dimension is discussed in connection with modularity, data base object model and redundancy check. To improve the perceptual dimension of knowledge quality we analyze the possibility of using the performance audit techniques. Thus way it can be offered to the managers the perception that data and knowledge have been well evaluated, in according with clear hypothesis, operational risks and with no missing analytical data. Two indicators, GPS - Quantitative Precision of the Supplier and TSD Total Stock Duration, are presented as examples of how the perceptual dimension can be improved by the performance audit.Knowledge Quality, Quality Dimensions, Perceptual Dimension, IT Audit

The software development process of ecommerce systems

Today, in the new economy, while the possibilities for software are seemingly limitless, so is the growing demand. The problem is that speed and quality have typically been opposing forces in software development, and they still are. In the past, businesses could sacrifice software quality to respect the deadlines, or compromise on software features to meet time-to-market deadlines. In the new Internet economy, it have no choice: the software developers must produce higher quality software. For this reason in the paper, we described the key points of software development process in the new economy, trends and major characteristics, the evolution of this process. In particular, the ecommerce system development methodologies which resolve the problems of e-business applications.ecommerce systems, software development process, CMS-Content Management Systems, new economy, new business

The ProCard mobile banking system

The mobile banking involves the use of some mobile telecommunication devices (such phones or PDAs - Personal Digital Assistants) in order to complete, in a secure manner, banking transactions (like payments, transfers, account information and so on). It doesn't matter where the user is physically located. Also, the hour when the services are requested is not important anymore, because, thanks to the internet banking, the offices are virtually opened 24 hours per day. The ProCard system represents a suite of applications used to perform mobile banking. It was intended to be a universal solution that allows EFT, Internet and mobile banking in a single package. No special software or hardware is requiredInternet banking, mobile banking, electronic transactions, electronic funds transfer, mobile terminal, PDA, SSL, parallel processing, grid networks, clusters of workstations, grid processing.

An Implementation Model of a Declarative Framework for Automated Negotiation

The subject of automated negotiations has received a lot of attention in the Multi-Agent Systems (MAS) research community. Most work in this field on the auction design space, on its parametrization and on mechanisms for specific types of auctions. One of the problems that have been recently addressed consists in developing a generic negotiation protocol (GNP) capable of governing the interaction between agents that participate in any type of auction. Though much has been said on this matter, the current results stop at the XML representation of specific negotiation mechanisms. In this paper we propose a declarative approach for specifying a generic auction protocol by using Belief-Desire-Intention (BDI) agents and the Jason programming language to represent the entities that communicate in an auction. In order to validate the claim on the generality of the proposed approach we have used the GNP to model two negotiation mechanisms: one for the English auction and one for the Dutch auction

The Information Security Management System, Development and Audit

Information security management system (ISMS) is that part of the overall management system, based on a business risk approach, that it is developed in order to establish, implement, operate, monitor, review, maintain and improve information securitysecurity, information management system, audit

Visualization of Accessible Multimedia Content in Web Pages

Multimedia content still presented on the web sites. The visualization of multimedia content by the users with disabilities, those that usually use screen readers, is extremely difficult. With the onset of the audio sequence of multimedia presentation it is difficult for users with visual impairs to listen the audio component of presentation and the audio version of the screen readers too, because the two audio streams cannot be controlled using only one volume control. Therefore, because of the difficulties to control the available audio streams and because of the difficulties to access the control buttons by people with disabilities, the multimedia content is often inaccessible for users with visual problems. More than this, the use of dynamic users’ interfaces is a critical problem because the screen-readers cannot detect the dynamics in content changes. The current paper presents some solutions for multimedia content production and distribution in distributed multimedia web presentations.Accessible multimedia content, Synchronized Accessible Media Interchange

ERP System Audit a Control Support For Knowledge Management

The ERP system supports most of the business system that maintains in a single database the data needed for a variety of business functions such as Manufacturing, SCM, Financials, Projects, Human Resources and CRM; the audit of this systems is necessary in order to give reasonable assurance to the company on its core system. Obtained evidence evaluation can ensure whether the organization's IT&C system safeguard assets, maintains data integrity, and is operating effectively and efficiently to achieve the organization's goals or objectives. The audit process respecting the methodology based on: gathering information and plan; obtaining an understanding of internal controls; performing test of controls and substantive tests, develop a control support on quality of flow of information and knowledge from formal perspective, for Knowledge Management in large enterprises.ERP systems, IT audit, information quality, knowledge management

A General Filter for Stretched-Grid Models: Application in Two-Dimension Polar Geometry

Variable-resolution grids are used in global atmospheric models to improve the representation of regional scales over an area of interest: they have reduced computational cost compared to uniform high-resolution grids, and avoid the nesting issues of limited-area models. To address some concerns associated with the stretching and anisotropy of the variable-resolution computational grid, a general convolution filter operator was developed.\ud \ud The convolution filter that was initially applied in Cartesian geometry in a companion paper is here adapted to cylindrical polar coordinates as an intermediate step toward spherical polar latitude–longitude grids. Both polar grids face the so-called “pole problem” because of the convergence of meridians at the poles.\ud \ud In this work the authors will present some details related to the adaptation of the filter to cylindrical polar coordinates for both uniform as well as stretched grids. The results show that the developed operator is skillful in removing the extraneous fine scales around the pole, with a computational cost smaller than that of common polar filters. The results on a stretched grid for vector and scalar test functions are satisfactory and the filter’s response can be optimized for different types of test function and noise one wishes to remove
