THOMAS EDISON STATE UNIVERSITY Systems Analysis and Design Name: Daniel Wakaba Professor: Rekha Bhowmik Student ID: 0569421 Course: 2017SEP CIS-320-OL009 Date: 01st Oct 2017 Title: Written Assignment 5 Introduction Nowadays systems are mostly controlled by the software programs rather than manually by users, it is a very important task for the development team to do a thorough system analysis and system design so that they can protect the Integrity of a system. Therefore, safeguarding system and its information are the ultimate goals of system controls. In this review, I will be discussing system controls, what are they and why are they so important. What is a system control? System controls are incorporated into various parts of a program during software development life cycle, whereby they are used for checks …show more content…
Moreover, this is a safety mechanism to defend the system information and data in case of disk crashing or data damage. When system analysis is being done during the initial phases, the assumptions are that the system will work without crashing. This event is a system control event to safeguard data in case of any eventualities. Moreover, any unauthorized user may hack or log in the system and take the data from disk drives and corrupt the data. However, backing up of the database is not included in the use cases due to the perfect technological assumptions. Undoubtedly, systems are not build based on failure, but this does not mean failure cannot happen. Due to perfect technological assumptions that the system will be working in a perfect manner most analyst don’t take this seriously during the initial stages of system analysis. However, pretending that technology is perfect is not a good idea, eventualities need to be handled in the best way possible, such as requesting a user periodically to a backup data. Restore the
Every piece of information must be traceable back to the data input that produced it. The main action of audit trail is captures a sources of all data items at the time of getting entrance into the system. The other constituent of input control and security involves data security rules and measures to protect data from being or lost or damaged. The records retention policy is the practice of storing documents in a safe location and making sure to see to legal requirements or business needs. Input security and control also involves the process of encrypting or encryption of data so only users with the code it software can read
Some software systems have a relatively short lifetime (many web-based systems), others have a lifetime of tens of years (large command and control systems). Some systems have to be delivered quickly if they are to be useful. The techniques used to develop short-lifetime, rapid delivery systems (e.g. use of scripting languages, prototyping, etc.) are inappropriate for long-lifetime systems which require techniques that allow for long-term support such as design modelling.
In order to prevent both intentional and unintentional alteration, and destruction of information, any software application needs controls to ensure the reliability of data. Here are two specific controls per each one of the three data control categories, and how each control contributes to ensuring the data reliability in the format requested.
Gardner Trucking Inc is a trucking company that has over 1200 freight trucks specializing in different deliveries of goods such as paper, cans, metal, and doors to companies such as Corrucraft, Budweiser, Pepsi, Metal Containers, and Home Depot. Each freight truck can make up to 10 stops a day delivering to different customers. With each location, paperwork such as proof of delivery, invoices, and bill of ladings must be turned in, along with driver logs by the driver to the central office so that it can be properly billed and filed away. With over 1200 trucks making on average of 5 stops, and 3 pieces of paper per stop along with 1200 driver logs, that comes to about 20,000 pieces of paperwork everyday that must be processed. The current process involves sending the paperwork to the central office via courier or by UPS. Everyday approximately 30 boxes of paperwork must be sorted, copied, entered into the system, billed to the customers, and then put into storage. Also, a copy of the proof of delivery and invoice must be sent to the customer so that the company can get paid. Gardner Trucking has approximately 40 employees in the processing department to handle the incoming paperwork as fast as possible. This process alone can take up to 5 days from the time a customers product gets delivered before a customer gets invoiced The paperwork must also be filed and stored properly for each customer for up to 1 year of all deliveries. Gardner Trucking has a warehouse along with several containers to store all the paperwork. Sometimes customers will lose the proof of delivery or say they never received it and request a copy be sent via email, fax or mail in order for the invoice to be paid. At that point, the paperwork must be found, a copy made, given to accounts receivable to send out and filed again. Sometimes the invoices do not get paid or deeply discounted because the proof of delivery could not be found (after spending many hours to locate it) to send to the customer.
This will allow for data to be analyzed and placed on a separate non-operational database. Essentially this will be synced version of the operational database and will provide a centralized view of the main database. This could also be used as a backup to the original database.
Software systems are discrete-state systems that do not have repetitive structures. The mathematical functions that describe the behaviour of software systems are not continuous, and traditional engineering mathematics do not help in their verification." In other words some software can be so large that thorough testing can be almost impossible and so bugs in the software can go unnoticed. An example of this was when an Atlas-Agena rocket veered off-course when it was ninety miles up. Ground control had to destroy the $18.5 rocket.
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
While developing a software many complex activities are required which in turn have dependencies along them. Large software projects require the involvement of programmers, documentation specialists, program managers, architects, database analysts, system analysts, , and trainers and last but not the least testers. Along with their independent responsibilities these persons are also responsible to maintain and keep a check on the software system quality as well.
Security consideration features for information systems will vary for the type of information held, but the basic features will hold the information securely. The major security features for the company systems will include a login using a user ID and password, user authorization, and priority access. The security features would also use the four access control models of Identification, Authentication, Authorization, and Accountability. The access control would use the mandatory access control (MAC), which is a structured and coordinated within a data scheme that rates the information collection and the users (Whiteman & Mattord, "Ch 6: Security Management Models," 2010). With the priority access, user authorization, and the user ID and password, the supervisor can authorize the correct access and rights to the employees. These features would prevent any employees who do not have access to the system from entering. The priority access will allow the employees to
The Risk Management Framework and associated RMF tasks apply to both information system owners and common control providers. In addition to supporting the authorization of information systems, the RMF tasks support the selection, growth, execution, assessment, authorization, and ongoing monitoring of common controls inherited by organizational information systems. Internal and external to the organization, helps ensure that the security abilities provided by the common controls can be congenital by information system owners with a degree of assurance appropriate for their information protection needs. (Locke & Gallagher,
The system development life cycle, also know as the SDLC, is the process of designing and developing a system or software to meet certain requirements. (“System development life,”). This cycle involves many different phases, in which the system is planned, analyzed, designed, implemented, and tested. There are five major phases in the system development life cycle: systems planning, systems analysis, systems design, systems implementation, and systems security and support. Each of these phases has a particular responsibility and certain tasks are perfumed in each phase.
Most health care providers currently utilize electronic health records (EHRs), or will in the coming future. Network collapses, glitches, power outages and flaws within the system all have the possibility of occurring. Due to the plethora of sensitive information contained within the health care field, health care providers need to form backup plans. These backup plans will serve as preventative measures in order to keep the integrity of the health care data intact. Therefore, contingency plans are a clear necessity within the field.
System identification is a process of developing or improving the mathematical representation of a physical system using experimental data. It has been applied widely in aerospace engineering, mechanical engineering and structural engineering for active control, model validation and updating, conditional assessment, health monitoring and damage detection. System identification techniques can utilize both input and output data or can only include the output data. [1]
The comprehensive approach that the configuration control employs ensures that the utilized data is correct to ensure that all the information sources and documents for all sections remain updated. Such is fundamentally made possible by the attention given to timely approval of the established information and the focus on checking the data to ensure that the parameters and steps adopted are appropriate. The significance of having a mechanism that would convey the correct information to the systems cannot be overstated. Such is considering the influence that information has in controlling functions affecting the project
The primary objective of system design is to analysis to thoroughly understand the organization’s informational needs or requirements to set the specifications (Satzinger, 2015). This system design is to structure the components of the final system, which serve to distributed the type of environment the user will do. When looking at application software components within the system design, the analysis needs to figure out the sub systems, and relationships to each part of the
