Computer Information System For Decision Support System

Classification of different types of ERP software

Describe about the Computer Information System for Decision Support System.

Information management system is important for any business improvement system and operational management (Ward & Peppard, 2016). ERP or enterprise resource planning are very important for integration of the business system. ERP technology and software are classified into industry specific ERP, Web based or cloud service ERP, small business ERP, and computer exchange ERP solutions (Leon, 2014). The strategies are developed for the improvement of the security function in the business organization.

In this assignment the various types of ERP models are being analyzed for understanding their impact on the business operations. The assignment consists of taxonomy of the ERP model for understanding the comparison between the outdated information system and the advanced information system. Various examples for ERP software are shown in the assignment and it would help in understanding the extent of the technological development in information system management. The suggestion provided at the last part of the report would be helpful in providing the effective ways for securing the information system for any business organization.

There are various types of enterprise resource planning software used in integration of the business system. They are classified into industry specific ERP, Web based or cloud service ERP, small business ERP, and computer exchange ERP solutions (Monk & Wagner, 2012).

Industry specific ERP: the Infor ERP is a ERP solution that offers the solution for manufacturing and distributing process of the industries (Nettstrater et al., 2015). The software solution has supported over seventy five thousand businesses across two hundred countries. The industry specific ERP are used by large scale business entities as they need customized operations for their business needs.

Web based or cloud service ERP: The advanced ERP system are broadly sued by many companies. However, there are some companies who use the web based software solution for the integration of the business activities. The cloud based server for business integration has been termed as SaaS or software as a Service. The cloud service ERP helps in accessing and storing the data over the internet based storage system. It would help in remote access of information and data. The cloud ERP provides the organization with fast and accurate access to the information system. Hence, it is ideal for all scales of businesses. However, it is best suited for small business models.

Small business ERP system: this type of ERP system is helpful for small operations like sales and order management (Nettstrater et al., 2015). The human resources management does not require large data house for small scale business organizations. Hence a lower scaled ERP system is beneficial for providing functionality to small scale business problems. It can be implemented at cheaper cost and is very ideal.

Computer exchange ERP solutions: Computer exchange ERP solutions are useful for helping the business centers in improving the efficiency of the operations (Chang et al., 2013). The outdated ERP are not liable for providing the required functionality to the business management. The upscale and updated ERP system would help in increasing the opportunities for accelerating the growth of business.

Information security architecture of Apple
The apple devices are the most secured device that is being used currently. The software consists of data protection class within the layers of app sandbox, user partition, OS partition and file system (Wonglimpiyarat, 2012). The hardware is protected by using kernel that consists of secure enclave and element. The Crypto engine and root certificates of apple are also used for protecting the device from any security issue.
Information security architecture of Microsoft
The information security used in Microsoft is based on the advent of threat modeling. Threat modeling is an analysis of the risk factors and threats for information security. The four core elements of threat model are processes, data stores, data flow and external entities. The security network architecture of information in Microsoft are protected from Spoofing(S), Tampering(T), Repudiation(R), information disclosure(I), denial of service(D), and elevation of privilege(E). Its acronym is STRIDE (Wonglimpiyarat, 2012). IPSec or transport security layer is used for authentication of the device. The field gateway is protected by using TLS RSA or PSK, RFC 4279, and IPSec protocols.

The taxonomy of ERP architecture shows five basic elements for the information management system (Ali & Cullinane, 2014). They are Management (Top Level), Strategic level, Tactical level, Operational level, and Integration and Realization.

Management (Top Level): It consists of Business class, Change management, Project management, and Training (Islam Nofal & Yusof, 2016). The management is the top most level of the ERP architecture and it is responsible for all the operations in the business organization. The communication process in the ERP system is very important as it holds all the operations of the organization together.

Strategic level: It consists of Implementation process, Hiring procedure, Benchmarking activities, and Evaluation of the outdated process.

Tactical level: It consists of Client consulting activity, Software selection process, and implementing approach for the information system.

Operational level: It consists of Business process, Configuration of the information system, finalizing the activities, and Going live that means implementing the information system (Islam Nofal & Yusof, 2016).

Integration and Realization: In this step the ERP architecture is implemented and the outcomes from the system are realized for the business organization.

The taxonomy of ERP architecture implementation for improving the legacy system can be understood from the provided figure.

The strategies that can be used for improving the information security and management in the organization are policy development, education and training, enforcement of the security model, information exchange, and co-operation (Peltier, 2013).

Policy development: The organization must encourage and adopt the appropriate laws, policies, rules, and agreements for information security management (Gray, Miller & Noakes, 2013). It would help in harmonizing the technical standards among the whole world. The promotion of the expertise would be greatly influenced by the formation of policy for information system.

Education and training: it would help in promoting the necessity of the information and security of the information stored over the database (Sacks & Pikas, 2013). The organization would have to make sure they have educated an trained them about the importance of the information system and its security.

Enforcement of the security policies: it would require providing access to the implementation of the policies recognized for information security improvement (Gray, Miller & Noakes, 2013). The organization would need to expertise and exercise ways for implementing security of the information system.

Information exchange: the information storage system must be made secured and the process of transferring must be made explicitly (Sacks & Pikas, 2013). The exchange of information must be related to the guidelines of the policies and their implementation in the information system management.

Co-operation: the security of the information system can be implemented by the co-operation of the employees (Peltier, 2013). The mutual understanding for the information security is necessary for any organization.

Conclusion

Information management system had held an important place for any business improvement system and operational management. Different types of the ERP are industry specific ERP, Web based or cloud service ERP, small business ERP, and computer exchange ERP solutions. The strategies that have been developed for the improvement of the security function in the business organization would help in understanding the information system management and it security features.
