...individuals. Many companies have been compromised and personal information obtained and used without authorization. It is very important to have computer and network security to keep hackers and malware from collecting data and destroying a computer system and network. Computer security protects all of the data that is stored on your computer. Every component should be protected that includes hardware, software, and data. The history of Network security started when hacking crimes started in the 1980’s. Robert Morris was a computer hacker that released a worm that affected 6,000 computer systems. It created a large monetary financial lost because of a computer worm. The Computer Emergency Response Team (CERT) was said to be form after the attack to inform users they had security problems. ”The Department of Homeland Security's United States Computer Emergency Readiness Team (US-CERT) leads efforts to improve the Nation's cybersecurity posture, coordinate cyber information sharing, and proactively manage cyber risks to the Nation while protecting the constitutional rights of Americans (US-CERT).” Hospitals have major concern in protecting computer and network security. The information in hospitals have very valuable information such as patient records, social security number and payment information. All of which is harmful if it gets into the incorrect hands such...

...Rail TCS Concept Simulator SEA developed the Train Control System (TCS) Concept Simulator for the West Coast Route Modernisation project. A team of SEA engineers has developed, operated and maintained the Concept Simulator since 1998. The Concept Simulator models the functional operation and inter-operation of key components of train control system architecture and the external systems to which the system interfaces. The simulator is valuable in the development and analysis of operational principles, and in assessing design trade-offs. The SEA-designed facility simulates operation at ERTMS Levels 1, 2, and 3. Components include a Communications Network, a Network Management Centre, a generic Interlocking, a Radio Block Centre, a Track Simulator including both conventional and TCS equipment, a Driver Desk, a European Vital Computer and a Driver MMI. The components are modelled using software-based simulations hosted on networked PCs. The simulator has been valuable in the engineering evaluation and validation of emergent system architectures, and enables system constraints to be explored and defined. ERTMS operational modes and the transitions between them are simulated and ERTMS principles and procedures are followed.

...PROFESSION ACT 2004 Page Number: [1] Version 1.0 – 201207 INTRODUCTION SECTION 2.7.22 SELF ASSESSMENT AUDIT The Legal Profession Act 2004 (“Act”) contains the key provisions governing the operation of Incorporated Legal Practices (ILPs) and is the source of the Legal Services Board’s (LSB) powers to undertake audits and investigations in respect of ILPs, their legal practitioner directors and executive officers. The LSB has the role of regulating ILPs to ensure compliance with the Act, the Legal Profession Regulations 2005, any legal profession rules and the general law. Working with the Law Institute of Victoria (LIV), the LSB will exercise its statutory role as regulator for ILPs while the LIV will have an educative and member-services focus. Section 2.7.22 of the Act provides that the LSB may undertake an audit to ensure compliance by the ILP with the provisions of the Act. The LSB requires every corporation that engages in legal practice in Victoria to undertake an internal (or self-assessment) audit of its compliance with its obligations under Part 2.7 of the Act. Part A of this form relates to information about your practice. The purpose of this part is to assist the LSB in understanding your practice better to ensure that the corporation is complying with section 2.7.22 of the Act. The information gathered under the LSBs investigative powers relating to audits (s.2.7.23) is confidential and will be used by the LSB in determining whether or not there are factors...

...about them one by one and in a proper research method and will compare them in order to contrast their difference and efficiency. Research Background One problem in understanding the phenomenon is that the size of these data sets the volume greatly exceeds the Data warehouse. A plane collects 10 terabytes of information from sensors every 30 minutes flight, while the Stock Exchange of New York collects structured information 1 TB per day. In the context of Big Data, volumes are reaching peta bytes, exa bytes and then soon to zeta bytes. For instance, Apple has just announced that 7 trillion send daily notifications to iOS devices. The explosion of information in social networks, blogs, and emails is characterized the presence of data key "unstructured" and "semi" in contrast with the data type “structured” is what is commonly handled in the Data warehouse. However, the concept of Big Data makes sense from the moment that not only the volume but also the speed and variety of data exceeds the processing capacity that can handle traditional IT systems into information of value to decision. This last feature, the value is the key...

...Chapter 8 – Approaches to System Development 1 Table of Contents ← Chapter Overview ← Learning Objectives ← Notes on Opening Case and EOC Cases ← Key Terms 2 Chapter Overview There are two closely related yet independent concepts in this chapter. The first important concept is that there are two types of Systems Development Life Cycle approaches—a predictive approach and an adaptive approach. The second important concept is that there are two types of development methodologies—a structured approach and an object-oriented approach. These are two separate concepts. Projects can be any mix of these two approaches, the approach to the life cycle and the approach to the methodology—predictive with structured, predictive with object-oriented, adaptive with structured, or adaptive with object-oriented. The chapter first presents and explains the differences in the life cycle approach—the predictive and the adaptive approaches. These two approaches are really a continuum and any give project may have elements of both approaches. The predictive approach to the SDLC is used for projects that are well understood and low risk. The adaptive approach to the SDLC is used for projects that are not well understood and are higher risk. Adaptive SDLCs are more iterative and allow the project team to adapt the project to changing circumstances. The other important concept that you should learn from this chapter are the difference between the two...

...Mather Worldwide (A) Document purpose: suggestions to increase acceptance of Ogilvy & Mather’s new Vison on employees below senior executive management. Problem definition December 1993: Charlotte Beers assesses the progresses made by the company after she became CEO: she realizes that clients love the Brand Stewardship concept, but most employees, below executive levels, have not embraced the newly created Vison. The problem I will focus in this document is the following: the majority of employees did not embrace the new Vison. I will analyze why this is a key problem, why it is happening and I will propose steps to accomplish more acceptance. Analysis Brief Background Major events have shaped the history of the company in the recent years: first the hostile takeover, 1989, then the loss of key accounts and credibility in the business. Many key senior employees have left in the 2 years following the takeover. The company Vison has been: “just keep doing the same thing, just better”, but the world around has been changing. The marketing business has clearly become more global in nature, with "mergers to form mega-agencies and the concept of transporting brands around the world", and customers are demanding for “more service at lower costs”. Re-creation Technically the type of organizational change Beers has to face as new CEO of the company is called re-creation: it’s a change introduced in response to an immediate demand, in this case the loss of customers and...

Critically evaluate the “half-life” concept, in light of Analog Devices’ strategy. What are the potential benefits and the limitations of the half-life concept? How would a company develop the half-life for different process? How is the half-life concept different from the experience curve concept? Answer: Benefits of half – life: Limitations of half life concept Difficult to determine half life as it is dependent on technical and organizational complexities Calculated based on historical data which may not give a very clear picture HALF-LIFE AS A TOOL BENEFIT Goal setting tool Rational determination of future performance Diagnostic tool Benchmarking improvement efforts against best practice for processes of similar complexity Measure of organizational learning To make comparisons with alternative methodologies. IMPLEMENTATION OF HALF-LIFE Half Life Learning Curve Rate of decline of defect level is constant over time With doubling of cumulative experience the unit cost drops by a constant percentage Concept generally deals with defects Concept generally deals with cost Defect reduction owing to a root cause being eliminated and subsequent tackling of the next root cause Cost reduction owing to the same action being performed repeatedly.
