When it comes to computers, there are many issues that can take place. One of them is a DNS attack, which bypasses firewalls and allows for the sending of spam emails and the hacking of pay per click ads. It can be difficult to avoid these attacks, and one must understand what causes them and how they can best be prevented and/or discovered. This paper addresses DNS attacks and related issues through the critique of two different articles.

Change Management -- a Case Study of British Telecom

This paper provides the technical report that reveals the database design for the departmental bookstore to track the sale and inventory data. The report identifies seven entities and their relationships for the database design. The report also identifies a firewall, encryption, intrusion prevention system (IPS) and IDS (intrusion prevention system) for the database security systems.

Merging up of small companies with large companies is most likely but the endeavor required wise strategy by keeping in consideration the both companies mission statement and user demands. Probability of high collision between the objectives is most likely in integration plan and sometimes after merging the company to be merging even lost its initial glory and stands nowhere in user community.

Peachtree in its IT planning process has lost clarity regarding their strategic goal for what they intent to accomplish with their systems along with a roadmap for achieving that goal. This should be the starting point of any large-sized institution going for an IT overhaul. The organization's acquisition over the years has brought diverse medical institutions under its fold, each unique in terms of its workflow patterns. Ranging from large and midsized institutions, trauma centers, nursing systems to rehabilitation facilities, each has its own set of unique work processes, overlaps between them. This poses inherent challenges to devise an integrated Information System--IS. Development of an integrated IS at Peachtree has to translate into increased efficiency which would seamlessly function across its distributed facilities in a hassle-free manner.

Business organizations have to keep themselves abreast of the changes in their business environment. In order to sustain in a challenging environment and achieve competitiveness in the industry, they have to ensure operational excellence and superior financial performance with each passing day (Attaran, 2004). With the evolution of Globalization and rapid advancements in the field of Information Technology, businesses find it quite harder to compete with the other industry participants with the help of their traditional business operations and processes (Kurtz & Boone, 2011).

Alcan's continued revenue growth is the result of the combined success of increasing sales in four main business units, in addition to growth through acquisition. The cumulative effects of these two factors have served to create a profitable business and one where a highly decentralized organizational structure dominates (Chang, Wang, 2011). The catalyst of the organization becoming so decentralized is the continued revenue gains made across four businesses, each competing in market areas that face heavy pricing and commodity-like market conditions. Despite the heavily process-centric based approaches the industry takes to supply chain management, production and distribution, Alcan has been also able to profitably grow sales in the more mature markets they compete in. The senior management and IT departments credit the highly decentralized nature of the enterprise-wide systems that run the company. During the time period of the case, Alcan generated $23.6B in sales in 2006, and has 68,000 employees throughout its global operations that span 61 countries. The four major groups include Primary Metal, Engineered Products, Packaging and Bauxite & Alumina. Each of these business groups have their own Enterprise Resource Planning (ERP) system and IT infrastructure. They each also have their own maintenance contracts with enterprise software vendors including SAP who the company pays approximately $100M a year in maintenance fees to. There are also the costs of operating over 400 different pricing systems, many of which duplicate functions across divisions as well. The new CIO of the company, Robert Ouellette, enters into a challenging situation and one that will require a completely different IT and organizational structure to succeed. Organizational Environment The Alcan organizational environment is highly decentralized to the point of there being four separate companies in the same corporation, each with its own entire value chain and supporting functions. As with the value chain concept, each of the four divisions has created its own main and supporting functions, and no two business units or divisions are the same. From the initial supply chain management and supplier quality management processes and systems to the supplier qualification, new product development, production and fulfillment including logistics, each business unit is significantly different than the other. When information systems and processes become unique to a given organizational business unit or division, the information and intelligence shared redefines the identity and over time, the core competencies of a business unit (Boh, Yellin, 2007). This is exactly what's happening in the four business units of Alcan during the time period of the case study. The Primary Metal, Engineered Products, Packaging and Bauxite & Alumina have in effect become their own companies, each with its own ERP, Manufacturing Execution System (MES), Supply Chain Management (SCM) and myriad of pricing and distribution systems. The case states that there are over 400 different pricing systems in place across the four business units or divisions. CIO Robert Ouellette and other senior executives see the potential for consolidating all systems together and creating a centralized IT architecture. Creating a highly centralized IT architecture and framework would require the fundamental structure of the company to change significantly. It would also require an entirely new IT architecture, followed by redefinition of processes, systems and procedures throughout the company. As the information platforms or technologies of a business define not only the performance of divisions but the structure and performance of business models over time, Robert Ouellette and his staff must think strategically as to how they will modify the overall organizational structure.

For any enterprise to attain its long-term and most strategic objectives, the need to have an agile, highly secure framework for managing their financial reporting and audit applications corporate-wide.
