Database Encryption Solution

Introduction Critical data in a database needs to be protected against internal and external threats. A database encryption solution can be used to achieve this protection in addition to providing the regulatory requirements. In the past, access control was used as a means of protecting information against access by unauthorized users. Access control did not prove very effective and this has led to the adoption of encryption where information is transformed into some form that cannot be understood by unauthorized users. Decryption is the process by which the transformed text is retransformed into a form that can be understood. This paper will seek to analyze a database encryption solution that will protect critical data against internal and external threats and at the same time meet regulatory requirements.
2. Choosing the Point of Encryption Encryption can be done at different places within an enterprise. Encryption is used to minimize the number of people who access the encryption keys. Before encryption, implementation decisions needs to be made (Mattsson, (2005, p.2). The most important thing is choosing the point of implementation. This helps in determining the work that needs to be done so that integration is effective and also determining the security model. Data needs to be protected both when at rest and during movement between applications and the database.
2. 1. Database-Layer Encryption In this case, an enterprise is able to protect data as it is being written and read from a database. Database layer encryption is done at the column level within a database table. It can be coupled with access controls and database security so as to prevent theft of critical data. This level of encryption protects data within the database management system and against threats such as storage media theft, database level…...

A New Way to Technology for Database Solution

...Set of atomic (indivisible) values. Attribute – it describes a component of the database, such as a table or a field. N-tuple – in mathematics, an ordered set of n elements called its components or coordinates. Relation Schema – It is representation of database highlighting relationships that we have created. Relation State – set of tuples that have the same attributes. Degree of a relation – number of attributes n of its relation schema. Relational Database Schema – Tables, columns and relationships that make up a relational database. Relational database state – is a union of all the individual relation states, whenever the database is changed a new state arise. 3.1.2 Why are tuples in a relation not ordered? - A Relation is defined as a set of tuples. Mathematically, elements of a set have no order among them: tuples in a relation do not have any particular order. In other words, a relation is not sensitive to the ordering of tuples. Tuple ordering is not part of a relation definition because a relation attempts to represent facts at a logical or abstract level. 3.1.3 Why are duplicate tuples not allowed in a relation? - Duplicate tuples are not allowed in a relation because it violates the specifications of the relational integrity constraints, particularly the key constraint which states that no two tuples can have the same values for their attributes at any relation state of a database. 3.1.4 What is the difference between a key and a superkey? - Superkey is......

Describe which perspective is most useful for each of the following employees: a programmer, a manager, and an internal auditor. How will understanding logical data structures assist you when designing and using database systems?</para></question><question id="ch04ques02" label="4.2"> Databases are possible because of their database management system (DBMS). As shown in Figure 4.2, the DBMS is a software program that sits between the actual data stored in the system and the application programs that use the data. As shown in Figure 4.4, this allows users to separate the way they view the data (called the logical view) from the way the data is actually stored (the physical view). The DBMS interprets the users' requests and retrieves, manipulates, or stores the data as needed. The two distinct views separate the applications from the physical information, providing increased flexibility in applications, improved data security, and ease of use. In a database system, the manager will rarely need to understand or be familiar with the physical view of the data. Nor, in most instances, will the internal auditor and the programmer as most everything they do involves the......

...Why Normalization Failed to Become the Ultimate Guide for Database Designers? Marin Fotache Alexandru Ioan Cuza University of Iasi, Romania Faculty of Economics and Business Administration Dept. of Business Information Systems Blvd. Carol I, nr. 22, Iasi, 700505, Romania Tel: + 40 744 497 654, Fax: + 40 232 217 000 fotache@uaic.ro ABSTRACT With an impressive theoretical foundation, normalization was supposed to bring rigor and relevance into such a slippery domain as database design is. Almost every database textbook treats normalization in a certain extent, usually suggesting that the topic is so clear and consolidated that it does not deserve deeper discussions. But the reality is completely different. After more than three decades, normalization not only has lost much of its interest in the research papers, but also is still looking for practitioners to apply it effectively. Despite the vast amount of database literature, comprehensive books illustrating the application of normalization to effective real-world applications are still waited. This paper reflects the point of 1 view of an Information Systems academic who incidentally has been for almost twenty years a practitioner in developing database applications. It outlines the main weaknesses of normalization and offers some explanations about the failure of a generous framework in becoming the so much needed universal guide for database designers. Practitioners might be interested in finding out (or......

Relational Database Solutions

...A relational database solution or relational databases have helped many companies gain more information about their operations by supporting simple operator queries, answering questions such as "What customer had the largest demand?" of "What customer ordered the largest shipment?" They are built to manage relationships and are ideal for starting contextual or genealogical information about processes. Before I continue I would like to explain what a relational database is and what it is derived from. Databases have been a staple of business computing from the very beginning of the digital era. In fact, the relational database was born in 1970 when E.F. Codd, a researcher at IBM, wrote a paper outlining the process. A database is an application that can store and retrieve data very rapidly. The relational bit refers to how the data is stored in the database and how it is organized. Since then, relational databases have grown in popularity to become the standard. A relational database allows you to easily find specific information. It also allows you to sort based on any field and generate reports that contain only certain fields from each record. Relational databases use tables to store information. With a relational database, you can quickly compare information because of the arrangement of data in columns. The relational database model takes advantage of this uniformity to build completely new tables out of required information from existing tables. In other words, it......

...transformation processes. In actual sense, relational database offers a solution to this menace. Data organization, keeping, storage, and retrieval among other essentials can easily be realized by adopting relational data management model. In this kind of model, tables are made use of in such a way that data items are formally described and organized according to their level of relations. The data item contained in a given table represents a relation. I am convinced beyond reasonable doubt that through the use of relational database model, an organization can be able to effectively manage their wide range of information encountered on a daily basis. Relational database model offers a more efficient means of managing data. Some of the huge benefits are discussed as follows. A relational database is a collection of relations or tables. The rows of a table in a relational database are known as tuples and each column of a table is called an attribute. By definition, a relation becomes a set of tuples having the same attributes. Operations, which can be performed on the relations are select, project and join. The join operation combines relations, the select queries are used for data retrieval and the project operation identifies attributes. The information oif the organization can be captured, manipulated, managed, and shared, and the value the database brings to the organization is immense. The advantages of a relational database are that they contribute to sound logical......

...Business Rules and Data Models DeMone Wallace Professor Carmen Flores CIS 111 July 25, 2015 Databases are very helpful because they contain and organize content on many different topics. Perhaps the three most important uses of creating and using a database would be to store, retrieve, and analyze information. A database can typically be accessed easily, and is usually stored on computers. Although an electronic version such as one created in Microsoft Access may be the first that comes to mind, there are many non-automated database versions as well, such as a personal phone and address book. Though the data and categories may change from business to business, the direct use of the information in a college student database can vary from marketing and advertising to obtaining new student enrollment and creating programs for funding. When collecting information for databases that are used for business purposes, certain laws must be followed that protect consumers to avoid the mishandling of the information. Data collected by college databases serve multiple purposes from marketing and advertising, to government and business reporting. Information that may be commonly useful in this type of database is date of birth, marital status, sex, income, race, location, and veterans/military status. When students are searching for colleges and universities online, student surveys collect demographic information used for tracking enrollment trends. In 2010, Collegetrend.com......

...4600-01 INTRO TO DATABASES CLOUD DATABASES SUBMITTED BY: ALICIA RUCKER INSTRUCTOR: DR. LUIS VIDAL SPRING 2016 Abstract A cloud database is a database that typically runs on a cloud computing platform. Users can run databases on the cloud independently, using a virtual machine image, or they can purchase access to a database service, maintained by a cloud database provider. There is a proposed 5 layer cloud architecture. The External Layer, which is the first, is closest to the user. The second layer is the Conceptual Middleware Layer. The third layer is the Conceptual Layer. In this layer programming techniques, transaction management, query processing and optimization are considered. The fourth layer is the Physical Middleware Layer, where interoperability between various platforms is considered. Last, there is the Physical Layer which is concerned with how data is stored and accessibility. A cloud database management system is a distributed database that delivers computing as a service instead of a product. It is the sharing of resources, software, and information between multiply devices over a network which is mostly the internet. An example of this is Software as a Service or SaaS. SaaS is an application that is delivered through the browser to customers. A database management system is a software package with computer programs that control the creation, maintenance, and use of a database. It allows organizations to conveniently develop databases for......
