Security Models

There is a direct relationship between security models, performance, and the functioning of the entire operating system. The purpose of selecting this topic is because, without a good security model in place, companies cannot be in a position to keep their private information safe. Acquisition and implementation of a proper security model is the first step towards having a successful company. There are three commonly used models: the Biba model, the Bell-LaPadula model, and the Clark Wilson model. This topic will make non-governmental organizations understand that they can also employ security models in their operations since they are not met for government departments only. Although there is no security model best over the others, the Clark Wilson model is the most preferred since it deals with integrity. With integrity in place, an organization is assured of confidentiality and security (McLean, 2018). The other purpose for this assignment is to make companies and organizations understand that there is no security model which is superior to the other. The functions and operations carried out in an organization determine the kind of security model which accompany should adopt.

Big Data and Social Networks

The topic is meant for companies to understand that they require data to meet their long-term or short-term needs. The data can either be from an internal or external source through outsourcing that leads to the generation of big data. The presence of big data helps a company to solve so many problems that it could be experiencing. It is applicable in marketing intelligence to assist in answering questions such as the impact of management on performance. Big data helps a company develop new marketing strategies that will help attain a significant market share by satisfying the needs of the target market segment (Fu, Liu & Srivastava, 2019). Big data is also used in cloud business intelligence to ensure a company's information security. Although, when big data and cloud intelligence are not used appropriately, they could lead to fraud, causing disappointments for the customers.

IT Acquisition and Implementation

Due to technology advancements, IT acquisition and implementation are becoming a primary concern for several companies. I have chosen this piece to ensure that companies are aware of what to do to ensure the successful acquisition and implementation of information technology. For companies to ensure they do not source the technology from outside, they can hire employees who are well equipped with knowledge on IT in terms of application and implementation. There are four primary methods that a company or an organization can use to acquire and implement IT successfully. The first method is purchasing software in its original form (Abd Rahman, Brookes & Bennett, 2019). The second one is purchasing software and making modifications for personalization in that it caters to your specific needs. The third one is leasing software to use on the company’s operations. The last method is developing individual software and later using it.

Data Governance Plan

Due to the significant and essential amount of data collected, a data governance plan is of great importance. Companies should understand that the more data is collected, the more it is likely to have insecurity issues. I have selected this topic to ensure that anyone who comes across this paper understands data governance and data governance plan. An organization should only collect data when a need arises to avoid data overload that cannot be governed. All the stakeholders should be allocated their duties to ensure a successful data governance plan. The governance board should ensure that all the set standards are met when transmitting data to customers. The managing director ensures the preparation of an annual business plan to ensure the goals and objectives of the organization have been met cost-effectively and in a feasible manner (Cheong & Chang, 2017). For a sound data governance plan, a program should be installed so that data can be restored into the system. There should be agency continuity for financial stability to cater to catastrophes.

MSIS Reflection Paper

Although my last goal was to blend my expertise in information technology with engineering in computer studies, I am now more interested in how technology can help solve customers' problems. Companies can increase a product's supportability and robustness to ensure they increase customer satisfaction and job satisfaction for employees. IT architecture, cloud computing, and other strategies developed in IT can be manipulated, especially if the company is customer-centric. With the information on the five topics discussed above, I will be more focused on what is required of me to ensure that IT is implemented in business and leads to success in most companies. Technology is also essential when presenting ourselves to our future employers by writing a cover letter or a resume. This is vital to graduates looking forward to seeking employment. A cover letter and a resume should catch or attract the eye of the employer before even reading.
