Physical Design and Implementation

SQL Injection is one of the many web attack mechanisms used by hackers to steal data from organizations. It is perhaps one of the most common application layer attack techniques used today. It is the type of attack that takes advantage of improper coding of your web applications that allows hacker to inject SQL commands into say a login form to allow them to gain access to the data held within your database.

In essence, SQL Injection arises because the fields available for user input allow SQL statements to pass through and query the database directly. SQL Injection is the hacking technique which attempts to pass SQL commands (statements) through a web application for execution by the backend database. If not sanitized properly, web applications may result in SQL Injection attacks that allow hackers to view information from the database and/or even wipe it out.

Oracle database privileges are of two types, system privileges and object privileges. The system privileges grant users power to perform the specified actions system-wide, whereas the object privileges let users perform particular actions on specified database objects. Microsoft SQL Server allows individual users to create private objects in the database. The system records the owner of every user object. Users can access objects only if the owner of the object has granted them access.

Administrators can define a custom password-verification function that checks the user password against company specific rules. In addition to pass SQL Server relies on encryption support that is built into the Windows operating system. It can automatically encrypt data and other network traffic as it travels between the client and server systems on a network.

...Physical Design and Implementation Tison Woodley Professor Smith Introduction to Relational Database Management System 2/24/13 In all cases there are many options that will be performed to help protect security in a database. Oracle for example has authentication which secure the entry. (oracle, 1993)Oracle supports the following methods of authentication by the network: * Third Party-Based Authentication Technologies * Public-Key-Infrastructure-Based Authentication * Remote Authentication The end user should only have access to all the privilege information, according to the policy of most business this will help prevent any type of misconduct by employee, intruder or hacker who are motivate by cracking codes. Oracle has a list of valid user; this gives them the option of being able to check the list for security issues. The user name and user password is a way Oracle protects against unauthorized user. In a major restaurant chain I recommend that all security measures be taken to help prevent any attacks because it will be a public accessible. There are many hackers that have the ability to hack into web pages and spread malware. In order to prevent attacks patching and testing could solve the problem but with the advance high tech technology business must work harder. If a strong firewall is built attacks will be prevent and hacker won’t be able to attack web application so......

The phases are system planning and selection, system analysis, system design and implementation and operation. Since the planning and analysis phase have successfully completed, now we are continue with the next phase, which is systems design of the POS System in ARZA Coffee & Cakes. System design under System Development Life Cycle was a conversion of description of the recommended alternative solution into logical and physical specifications for the system starting from the input until the output screens consists of report, databases and computer processes. By that action the company might ease to reveals the real systems from which all the programming and system construction can be accomplish. This system could be implemented into any hardware and software since it is not tied up to any of the specific one. However, the logical design will illustrate the functions of the system in all aspects. In the physical design, the logical design will be interpret into the physical or technical specifications by convert the systems data to the structured systems design.

Implementing Physical Design

...After a brief research of the latest versions of the following database management systems (DBMSs) on the market: Oracle 11G, Microsoft SQL Server, MySQL, and IBM DB2. I found the following information about each DBMS’s. Oracle 11G The biggest advantage Oracle 11G has is that it can help you create customized database applications. Instead of getting a standardized database program out of the box, you get a program that can be customized to fit your needs. This makes it possible to create a database that only has the features you need. Another advantage is Data Mining. It makes it possible to find relationships in data that would otherwise be difficult to find on your own. As good as the above sounds it also comes with a couple of BIG disadvantages. The biggest would be the cost, if you plan on using the program on multiple computers, you will need to buy licenses for each computer. If you plan on making the software available on many computers, these costs can really add up. Another big disadvantage is it comes with a learning curve; this is not something that you can pick up in a short period of time. Microsoft SQL Server MS SQL Server is a Client-server relational database system, with no UI development tools built in. Some of it advantages are, Maintenance its has lots of tools for maintenance, can do most of it with users in DB. It is user friendly, great security, it minimizes redundancy, and it is very consistent. It also works great on an enterprise scale it is......

...Stephanie Cook ITM 5400 FALL I 2013 System Analysis, Design and Implementation Professor Al Marcella Cook_7A 1. Should Top Sail implement a Web-based system? Why or why not? I do feel that Top Sail should implement a Web-based system in order to be effective in the time-sharing and rental broker business. Most every major company as well as brick and mortar companies are breaking through with Web based systems. Customers look to make everything convenient for them. Purchases and rentals of most all products via the Internet is how most customer are buying now days therefore this is a must for Top Sail. They need a system that will display relevant information pertaining to rentals, availability and prices and exactly what potential renters prefer and/or looking for. 2. What software acquisition options are available to Top Sail? The software acquisition options that are available to Top Sail must begin with the acquisition process. Step 1 is to evaluate the Information System requirements and prepare a request for proposal or a request for quotation, Step 2 is to identify potential vendors or outsourcing options, Step 3 evaluate the alternatives, Step 4 is to perform cost-benefit analysis, Step 5 prepare a recommendation and Step 6 implement the solution. They can develop a system, buy a software package or customize a software package. In Top Sail’s case customizing a software package would probably be the best route to take and in......

Systems Design, Implementation, and Operation

...CHAPTER 22 SYSTEMS DESIGN, IMPLEMENTATION, AND OPERATION SUGGESTED ANSWERS TO DISCUSSION QUESTIONS 22.1 Prism Glass is converting to a new information system. To expedite and speed up implementation, the CEO asked your consulting team to postpone establishing standards and controls until after the system is fully operational. How should you respond to the CEO’s request? The consulting team should strongly advise the CEO that postponing standards and controls is not advisable. Rather than save time and money, the company will probably lose time in the future when unanticipated problems and weaknesses arise due to the lack of standards and controls. The following are reasons why performance standards and control procedures should be established before the system becomes operational: * Internal control considerations must be taken into account when assigning job responsibilities. * Job descriptions and work schedules must include the various control procedures. * Performance standards associated with each position must be considered when selecting personnel to operate the system. * Documentation standards and data security provisions must be formulated before the system can be operational. * Error checks must be built into all computer......

Design and Implementation of a Bio-Metric (Fingerprint) Clocking System

...terrorism. Researcher refers to Biometric as a solution for detecting user’s identity and security challenges emanating in this modern day. Biometric identification is any automatically measurable, robust and distinctive physical characteristic or personal trait that can be used to identify an individual or verify the claimed identify of an individual. Biometric science utilizes the measurements of a person’s behavioral characteristics (keyboard strokes, mouse movement) or biological characteristics (fingerprint, iris, nose, eyes, jaw, voice pattern, etc). It is the features captured that is being transformed digitally into a template. The recognition software can then be used to discover an individual as the person they claim to be. Fingerprint recognition is the most common biometric method adopted in identification of a person (Ismail 2009). Since some parts of the human body are used in biometrics, the issue of getting lost is not possible and for password to be easily guess can be easily avoided.   Also, utilizing biometrics in most cases can be said to be more efficient when speed is considered and convenient than employing password and ID cards method. Using a particular person’s fingerprint as a form of authentication is just like using natural physical data as a password. The benefit of using biometric authentication is that it is absolutely distinct to each person. There are no two different individuals with the same fingerprint, it is difficult and impossible for......

Logical Design and Physical Design

...Logical Design and Physical Design CMGT 555/ Systems Analysis and Development   Throughout the whole process of system development, there are designs that take place before any coding or setup takes place. During this time, phrases like logical design and physical design get tossed around a lot, but what are they and what do they mean? In short, the logical design defines what must take place, not how it is accomplished. The logical design is like a set of blue prints, it describes the actual processes of entering, verifying, and storing data. In this paper we will explain when logical designs and physical designs are used, what design information a logical design and physical design contain and any similarities or differences. Figure 1. Example of Logical Model and Physical Model for an ERD Relationship Diagram (Compare Logical and Physical ERD, 2009) The direct definition of a logical design “is the Conceptual Blueprint of a software application, illustrating entities, relationships, rules, and processes (Thibeault, 2011)”. So what is the logical design is used for? The logical design contains all the business entries, what each entries attributes are, and relationships among entries. Now the logical design to some is misleading because they often confuse it with detailed technical design, even though the goals for these two are not similar at all. Now when do we use the logical design? That question is simpler to answer; it usually starts during the......

Systems Design, Implementation and Operatio

...SYSTEMS DESIGN, IMPLEMENTATION AND OPERATION In chapter 18 we focused on the first phase of the Systems Development Life Cycle – Systems Analysis. Chapter 20 deals with the remaining four phases: - conceptual systems design - physical systems design - systems implementation and conversion - operation and maintenance CONCEPTUAL SYSTEMS DESIGN In the conceptual systems design phase, the developer creates a general framework for implementing user requirements and solving problems identified in the analysis phase. As shown in Figure 20-1 on page 747 HC (page 637 SC), there are three main steps in conceptual design: 1. evaluating design alternatives, 2. preparing design specifications, and 3. preparing the conceptual systems design report. [pic] Evaluate Design Alternatives There are many ways to design an AIS, so accountants and others involved in systems design must continually make design decisions. [pic] The design team should identify a variety of design alternatives and evaluate each with respect to the following standards: 1) how well it meets organizational and system objectives, 2) how well it meets user needs, 3) whether it is economically feasible, and 4) what its advantages and disadvantages are. The steering committee evaluates the alternatives. Table 20-1 on page 748 HC (page 638 SC) presents examples of conceptual and physical design considerations and their corresponding design......

Design and Implementation of Solar System Simulation

... Similarly, Inverters are static power converters that produce an ac output waveform from a dc power supply. The dc power from SEPIC is fed to inverter to get ac output power (Chenvidhya et al, 2008). A Bi-Directional DC-DC Converter (BDC) is connected between the Sepic Converter and Inverter. BDC is used to store the dynamic energy in battery and supply to load when there is overcast sky or at night (Lin et al, 2008). For sinusoidal ac outputs, the magnitude and frequency should be controllable. This is done by comparing a sinusoidal wave of the same frequency as inverter output against triangular carrier frequency wave. This technique called sinusoidal pulse width modulation (SPWM) mainly used because of its simplicity and ease of implementation. The output voltage magnitude is controlled by closed loop control system using PI controller (Balathandayuthapani et al, 2010). As the capacity of PV system growing significantly, the impact of PV modules on power grid can’t be ignored. They can cause problems on the grid like flicker, increase of harmonics, and aggravated stability of the power system. To both increase the capacity of PV arrays and maintain power quality, it’s necessary to comply with the technique requirements of the PV system, such as fault-ride-through capability and harmonic current regulation. Especially when a large scale PV module is connected to the grid, the effects on the grid may be quite severe. Therefore, the system operation and system stability......
