Introduction
The term legacy system has distinct meanings for different individuals. For numerous people, it describes archaic mainframe or dumb-terminal software programs from the 1970s and 1980s (Weber, 2006). To other individuals, it may infer the client/server applications from the 1990s or web applications from the late 1990s (Weber, 2006). The chief point is that each one of these distinct architectures presents different risks that must be thoroughly understood and properly managed (Weber, 2006).
The aim of this research is to assess security risks with legacy systems. Research has uncovered that in spite of the information technology (IT) industry's diligence to advance the model of operating systems (O/S) employed, a substantial number of people elect to continue using outdated O/S for many of their most crucial software applications (Lamb, 2008). Topics covered in this assignment include an evaluation of legacy information systems at the NYS Office of Mental Health, security risks posed with legacy systems and the lack of skilled workers for modernization projects, and a defense of why legacy systems do not pose a problem.
Risk Analysis
The assignment research revealed that legacy programs endure due to the risks and expenditures of changing them (Lamb, 2008). Legacy replacement strategies can flop, not only injuring the reliability of the IT unit, but also the livelihoods of management (Lamb, 2008). The efforts and expenses required in system testing and the possibility of a colossal end-user reskilling program can be enormous (Lamb, 2008). Funds for upgrades are challenging to acquire due to the fact IT budgets are split amongst preserving the status quo and delivering modern functionality (Lamb, 2008). ...

...to leverage legacy applications may seem beneficial, but it is not. A single breach can result in the destruction of a business’s profits and reputation. For many legacy products, the vendors, many decide to no longer patch or keep up to date with known vulnerabilities. This can present high risks to the business who continue to use them. It is not always necessary to scrap or replace legacy applications. Transformation is a feasible option if the current applications are of good quality and a reasonable fit to business needs (Good, 2002). Organizations will have to weigh the benefits of maintaining a legacy O/S against security worries and the cost of protecting it by means other than patching (Lamb, 2008). Supporting a legacy operating system in an enterprise is as much about risk management as it is about traditional IT service management (Lamb, 2008).

However, I feel users had a different vision/perspective on security mechanisms and they trusted each other during those times and did not have to worry about protecting their information (this is how exactly, one person’s ignorance becomes another’s person’s - hacker, here bliss). This book helps us to understand the vulnerabilities; its impacts and why it is important to address/ fix those holes.
As the world is constantly changing in terms of program needs and the requirements to achieve them, there is a demand for innovative and tactical ways to increase success in achieving project objectives. The ever-changing technological climate, market dynamics, relatively short-lived solutions and the arduous integration of business and I.T., have proved stumbling blocks in managing complex programs and ultimately attaining desired results on time and on budget.

Security helps the organization meet its business objectives or mission by protecting its physical and financial resources, reputation, legal position, employees, and other tangible and intangible assets through the selection and application of appropriate safeguards. Businesses should establish roles and responsibilities of all personnel and staff members. However, a Chief Information Officer should be appointed to direct an organization’s day to day management of information assets. Supporting roles are performed by the service providers and include systems operations, whose personnel design and operate the computer systems. Each team member must be held accountable in ensuring all of the rules and policies are being followed, as well as, understanding their roles, responsibilities and functions. Organizations information processing systems are vulnerable to many threats that can inflict various types of damage that can result in significant losses (Harris, 2014). Losses can come from actions from trusted employees that defraud the system, outside hackers, or from careless data entry. The major threat to information protection is error and omissions that data entry personnel, users, system operators and programmers make. To better protect business information resources, organizations should conduct a risk analysis to see what
Problem Statement: In 2003, Zara's CIO must decide whether to upgrade the retailer's IT infrastructure and capabilities. At the time of the case, the company relies on an out-of-date operating system for its store terminals and has no full-time network in place across stores. Despite these limitations, however, Zara's parent company, Inditex, has built an extraordinarily well-performing value chain that is by far the most responsive in the industry. Therefore the major problem to the company is to decide whether it has to upgrade the present system and by doing so, risking the reliability they have with the current system or to continue with the present DOS based system which will not be compatible for future changes or improvements.
Hardware, software, support and maintenance costs grow each year with multiple systems in each local region running different types of software and hardware. The application and hardware support teams are larger than could be possible with one integrated solution.

As the internet is becoming faster and faster, an operating system (OS) is needed to manage the data in computers. An Operating system can be considered to be a set of programed codes that are created to control hardware such as computers. In 1985 Windows was established as an operating system and a year earlier Mac OS was established, and they have dominated the market of the computer programs since that time. Although, many companies have provided other operating systems, most users still prefer Mac as the most secured system and windows as it provides more multiple functions. This essay will demonstrate the differences between windows
As electronic commerce, online business-to-business operations, and global connectivity have become vital components of a successful business strategy, enterprises have adopted security processes and practices to protect information assets. But if you look at today's computing environments, system security is a horrible game of numbers: there are currently over 9,223 publicly released vulnerabilities covering known security holes in a massive range of applications from popular Operating Systems through to obscure and relatively unknown web applications. [01] Over 300 new vulnerabilities are being discovered and released each month. Most companies work diligently to maintain an efficient, effective security policy, implementing the latest products and services to prevent fraud, vandalism, sabotage, and denial of service attacks. But the fact is you have to patch every hole of your system, but an attacker need find only one to get into your environment. Whilst many organisations subscribe to major vendor's security alerts, these are just the tip of the security iceberg and even these are often ignored. For example, the patch for the Code Red worm was available some weeks before the worm was released. [02]
Microsoft was able in the OS segment to double their revenue per PC when Windows 3.x emerged which still needed MS-DOS to run. Most of the sales Microsoft made were to OEMs who would take the additional step of installing Windows on a computer’s hard drive. This strategy was effective in that the cost of production was relatively low, as an OEM may only need a single master copy to do the installation. The costs to Microsoft would largely be bore in R&D expense rather than production. As part of the Microsoft business model for this segment, Microsoft designed their OS to need periodic upgrades. The upgrades did come at a cost, and in essence, Microsoft was able to create an “annuity” stream for the Microsoft OS segment. In this segment, Microsoft had a monopolistic structure that allowed them to realize huge returns, especially during such a period of technological growth and rapid obsol...

Computers; they are a part of or in millions of homes; they are an intricate part of just about every if not all successful businesses, the government, and the military. Computers have become common place in today’s society and the lives of the people who live in it. They have crossed every national, racial, cultural, educational, and financial barrier, which consequently ushered in the information age. A computer is a programmable electronic device that can store, retrieve and process data, and they come in all shapes, and sizes. They can be used for and in just about anything. As stated before, they are used in just about every aspect of modern society. They are so fundamental to modern society that it would be disastrous to society without them. As stated before, there are many areas in modern society that are run by computers. They play an intricate part of millions of homes in the world. Office workers in business, government and the military may use them to write letters, keep rosters, create budgets, find information, manage projects, communicate with workers, and so on. They are used in education, medicine, music, law enforcement, and unfortunately crime. Because computers have become such a part of the world and how it operates, there is a tremendous responsibility for those who are in control of these computers and the vital information that they carry, to manage and protect them properly. This is management and protection is vital because any loss or damage could be disastrous for the affected entity. For example, a mistake or intentional alteration of a personal credit file could affect ones ability to buy a car or home, or can lead to legal actions against the affected person until the mistake or intentional alteration has been corrected. Therefore, with the advent of computers in the information age, and all of the intentional and unintentional violations against them, comes the need to safeguard them and the information they carry with strong systems and policies of computer security.
Effectively integrating information technology (IT) into an organization’s business processes is critical if the organization wants to increase productivity and remain profitable. IT includes items such as the systems software, application software, computer hardware, and the networks and databases that help manage the organization’s information. When implementing quality standards and processes that are forever changing in the IT world, organizations must balance these changes while continuing to rapidly implement new systems technologies in order to stay competitive.
Computer Economics, a research and consulting firm, surveyed 209 IT organization worldwide regarding their IT investment plans. The leading trends “were identified as low risk/high reward based on their cost predictability and their positive return on investment for organizations within two years’ time.” CRM tops the list for 2014 (Mackie, 2014)
