Introduction
Databases have become one of the most power pillars within organizations, regardless of size, industry, or geographical location. Databases are used for the sole purpose of storing and retrieving pertinent information, that in many cases deliver a vital blow to operations in any organization, and for this sole reason, hardware and software make database security a paramount feature that must not be overlooked.
Database security issues cover a wide spectrum; however, this paper will discuss database issues as related to database applications mainly using Oracle’s database application. Embedded security features accompany many database applications; however, often times these features are not properly enabled, therefore, security

The term “hardening” is often used to describe the removal of database vulnerabilities, but the term can also apply to computer systems hardware too. In the relationship to data, hardening there is a three step process that is used to evaluate the degree of hardening applied in hardening or securing a database. The primary stages of hardening a database consist of locking down access to resources, disabling unnecessary functions, and applying the principle of least …show more content…
In her article, The 10 Most Common Database Vulnerabilities, Ericka Chickowski (2010) explains that unnecessary enabled database feature rank number four out of ten, of the most vulnerable exposures of entrance into database breaches. The outbox configuration path for database applications vary from application-to-application thus it is not a one size fits all type configuration path that can be assumed by DBA’s, but a clear understanding of what is necessary versus unwanted must be carved out prior to beginning and installation. Planning and understanding what is desired in the operation of database can reduce risk of zero-day attacks, but it can also simplify database patch management, which leads me to the final element of the three primary database hardening
Security helps the organization meet its business objectives or mission by protecting its physical and financial resources, reputation, legal position, employees, and other tangible and intangible assets through the selection and application of appropriate safeguards. Businesses should establish roles and responsibilities of all personnel and staff members. However, a Chief Information Officer should be appointed to direct an organization’s day to day management of information assets. Supporting roles are performed by the service providers and include systems operations, whose personnel design and operate the computer systems. Each team member must be held accountable in ensuring all of the rules and policies are being followed, as well as, understanding their roles, responsibilities and functions. Organizations information processing systems are vulnerable to many threats that can inflict various types of damage that can result in significant losses (Harris, 2014). Losses can come from actions from trusted employees that defraud the system, outside hackers, or from careless data entry. The major threat to information protection is error and omissions that data entry personnel, users, system operators and programmers make. To better protect business information resources, organizations should conduct a risk analysis to see what
According to research, the people accountable for managing an organization’s database are called database administrators. The importance of a database administrator in a society should not be overlooked or treated with levity because they are fully in charge of data’s and information. Some of the examples of popular database management systems are My SQL, Oracle, etc. One of the major roles of a database administrator is to ensure database security. He or she is in charge of fixing security issues and complications that could
Every organization, big or small, should have some level of security policy to protect their proprietary information. While the intensity and depth of an organization's security policy depends heavily on the nature of their business, common guidelines are mentioned in this paper that apply to all policies. One of the most important things to remember is that employees are a critical component to a successful security policy. It is the organization's job to ensure that their security policy is widely distributed and understood.
Since the success of our jobs and National Security rely heavily on the maintenance and tracking of personnel security clearance information, information security information and industrial security information, what better way of achieve our goals then to develop a relational database which can track and monitor the progress of these three area disciplines. Microsoft Access is a relational database allowing for the quick analysis and retrieval of vital security information. Capron (2000) defines a relational database as, “A relational database organizes data in a table format consisting of related rows and columns” (p.404). Since all of the computers used in our security division are personal computers, it only seems logical to implement a relational database in order to manage our critical and sensitive security data. Nickerson (2001) supports the need for a relational database to effectively manage data on a personal computer by stating, “Almost all common personal computer database programs use the relational approach” (p.80). There are many benefits in using Microsoft Access. We will discuss some of them in this analysis.
This paper was written to show the similarities and differences in five different databases. It compared Access, MySQL, SQL Server, DB2, and Oracle in six different areas. It found many similarities in functionality, but large diversity in pricing.
Security is of the up most important portion of this system. All data must be safeguarded from outside influences.
Substantially, to fundamentally elucidate an information system, it is essentially a connected set of elements produced by people and managed through computers which allows the collection and distribution of data, to summarise the term it is generally a database. Data is a plural for datum which are elementary recognisable facts, information is datas that has been correlated so that context is formulated. To interpret data security, it is an assortment of facts which is translated to information secure on an encrypted server due to its personal state. In addition, the majority of security systems within modern technology are encrypted with pass-codes. However, database management systems (DBMS) can be breached in several ways including weak
Data warehousing is a difficult system and has to have the capability deliver quality data. An operational database is one which is used by organizations to run its day to day database activities. They are designed to handle rapid transaction processes with systematically updates. Velocity is important to operational databases. They are most commonly operated by office staff, and are on the order of megabytes of data to gigabytes. Database consistency checks and constraints are rigidly enforced. They contain the latest technology necessary to operate organizational functions.
Databases contain sensitive and important information about an organization. The basic element of any organization is to protect these information resources that support the critical operations of the organization from unauthorized access, modification, or disclosure.
High availability of database system, in which unplanned downtime is no more than seconds or only a relatively few minutes per year, is frequently a key objective in a data protection strategies, and one of the keystones of business continuity. However, an too much emphasis on high availability can lead to problems with data preservation (all the money goes into keeping the systems up and very little goes into preventing data loss when they go down), data responsiveness (fault-resilient storage often does not restore as quickly), and data confidentiality (all the money goes into keeping the systems up and very little goes to protecting data from unauthorized exposure). As a result, an organization may not meet its real data protection goals and probably will spend more than necessary for data protection.

Inconsistently storing organization data creates a lot of issues, a poor database design can cause security, integrity and normalization related issues. Majority of these issues are due to redundancy and weak data integrity and irregular storage, it is an ongoing challenge for every organization and it is important for organization and DBA to build logical, conceptual and efficient design for database. In today’s complex database systems Normalization, Data Integrity and security plays a key role. Normalization as design approach helps to minimize data redundancy and optimizes data structure by systematically and properly placing data in to appropriate groupings, a successful normalize designed follows “First Normalization Flow”, “Second Normalization Flow” and “Third Normalization flow”. Data integrity helps to increase accuracy and consistency of data over its entire life cycle, it also help keep track of database objects and ensure that each object is created, formatted and maintained properly. It is critical aspect of database design which involves “Database Structure Integrity” and “Semantic data Integrity”. Database Security is another high priority and critical issue for every organization, data breaches continue to dominate business and IT, building a secure system is as much important like Normalization and Data Integrity. Secure system helps to protect data from unauthorized users, data masking and data encryption are preferred technology used by DBA to protect data.
Some faculties and departments are already using Oracle applications in their day-to-day operations. As time goes by, more and more information users will be working with an application based on Oracle database technology. If you get the opportunity to be a member of an application development team, you will become familiar with the workings of Oracle and relational databases. Other users may have to learn about this popular database management system through their own experience. This article is for our readers who, as of yet, have no access to Oracle databases but have a yearning for learning what they're all about.
Moreover, E-commerce has widely recognized nowadays among people. Therefore such data should be secure in databases and privacy of data should be maintained.
In our world, people rely heavily on the power of technology every day. Kids are learning how to operate an iPad before they can even say their first word. School assignments have become virtual, making it possible to do anywhere in the world. We can receive information from across the world in less than a second with the touch of a button. Technology is a big part of our lives, and without it life just becomes a lot harder. Just like our phones have such an importance to us in our daily lives, database management systems are the same for businesses. Without this important software, it would be almost impossible for companies to complete simple daily tasks with such ease.
