Enhancing database security by restricting the access of users Database security mainly involves the protection of database by ensuring the usage of management software. Databases should have limited access, and unknown users should be restricted to use the databases. The purpose of securing databases is to prevent the attacks of malicious software. Illegitimate usage is also limited. Tools, processes and technologies should be adapted to ensure its security. Relationship between roles in databases and users A user can have access to a database based on their assigned tasks and privileges. Users can be categorized into superusers, object owner and everyone else. The superuser is usually the administrator who performs database-related functions. The object owner is the type of user who can create a specific database object (schema or table). Lastly, public users fall under the category of “everyone else.” They can also be regarded as non-superusers, and they play the role of PUBLIC because they have been granted by the superuser to play this role. They do not own the objects. Roles are assigned to different types of users. The…

Significance of Access Control in Database security – annotated bibliography Kuijper, W., & Ermolaev, V. (2014, June). Sorting out role-based access control. In Proceedings of the 19th ACM symposium on Access control models and technologies (pp. 63-74). Access control modeling framework based on user roles is a popular choice. The researchers have worked to determine a portion of popular framework and base their work upon the fact that the classic role-based access control would come up when aspects of subject management and permission management are blended into a unitary indirection object. In the study, the researchers have recognized the different perspectives of administration and have presented two principal objects of indirection – the demarcation (exclusive applicability on permission) and the proper role (exclusive applicability on the subject). These two objects were then linked to determine a third perspective – access management, and administrative perspective that can enable the organizations to enhance their scalability. The main principle would be to decouple the responsibility of abstraction maintenance over the subject (subject assignment as per proper roles), permission set abstraction maintenance (permission assignment into…

Databases privacy (through encryption) Introduction Organization do value their database security. Databases are a treasure trove of sensitive information that contain data ranging from the customers’ personal information and confidential competitive information to the organization intellectual property. If lost or stolen, data, especially those relating to the customer data do result in damage of the brand image, competitive disadvantages and the severe fines. As a result, database privacy of security is a top priority for the organization IT director (Hamdaoui, 2017). Traditional databases security still exposes such crucial information and is not sufficient in protecting the business. The modern means of database security which involved encryption is a more secure method of ensuring an organization databases security and privacy. In terms of the databases encryption, the encryption secures actual data within the databases and protects backups. Database privacy through encryption means that data of an organization remains safe even in the scenario where there is a breach of data. Modern approaches in the database encryptions like the use of the transparent data encryption TDE architectures introduced by Oracle and Microsoft…

Quality Control Data Proposal Introduction Data quality control refers to the process of regulating and monitoring the utilization of data for a process or application (Anderson, 2018). This process is done both after and before Data Quality Assurance, which involves the discovery of inconsistency of data and correction. Quality data is essential in organizations because, with it, the CEO will be able to understand or stay in touch with his clients. This paper is organized to establish key data points that will help in the identification of problem areas in the quality control process in BIDCO Company. It will discuss the essential data in assessing quality control, review the identification strategy for those key points, determine the presence, and formulate a quality control proposal for BIDCO Company. Identification of essential data in quality control When gathering data, the information collected must be of high quality such that they can be reliably used to identify problematic areas in the quality control process and in making sound decisions (Senior, 2015). The satisfaction of the customers- I will provide data on whether the…

The significance of Access Control in Database security Task 1 Introduction Database security can be defined as the measures that an organization must take so its databases can be protected from intrusions and threats. Threats can either be external or internal. The purpose of ensuring database security is to prevent the deliberate attacks of hackers and preventing the misuse of data. Again, access must be given only to authorized individuals so that the incidences of data breaches can be controlled. Important information and sensitive customer-related must be secured devotedly. Access control can be divided into two components. These are authorization and authentication. The authentication method helps in verifying the real identity of an individual. On the other hand, authorization means whether a user ought to be allowed before he or she is attempting to access data for transaction-related purposes. Access control can be divided into various types, such as Role-Based Access Control (RBAC), Discretionary Access Control (DAC), and Mandatory Access Control (MAC), and so on (Sandhu & Samarati, 1994). In this paper, the rationale behind choosing the topic shall be…

Database Design: Hotel Reservation System Introduction The database design I will use for the proposal will assist in hotel room reservation. The system created will enable the hotel managers and customer service agents to keep records of rooms, reservations booked, and guests. The hotel room reservation system will use SQL. This type of database should facilitate secure storage, management, and retrieval of data by the use of tables (Li & Manoharan, 2015). The database design is contingent on the use of four basic tables for storing the data. These tables will include room, reservation, guest, and reserved_room. The rooms table should enable the system users to manage details of the rooms concerning the room number, name, and status, i.e., occupied or available. The status can be represented by values 0 and 1. It should allow the users to understand whether or not, the room can be reserved. The guest table should inform the system user about the names of the visitor and their contact details. The table should store and retrieve the first and second names of the guest, their…

data security and safety In an IT environment, data security and safety is one of the vital components that ensure the proper functioning and the principle of least privilege is regarded as one of the useful approaches of computer security. The principle mainly ensures data security by restricting the access of unauthorized users. They are given limited entry but fair enough to complete their job duties. Here, “users” indicate the employees or contractors who do not need access to all kinds of databases. The POLP approach reduces the number of liabilities, and most importantly, it reduces errors and disruptions in the computer network systems. Enterprises face risks associated with data breaches and attacks of malicious software. The necessity of restricting the nuances arises, and the principle of least privilege can resolve the issue. It is a computer security principle that network administrators implement in order to reduce incidents related to networks and computer systems. The users are given the least amount of privileges, and consequently, the chances of hacking reduce. The enterprise pathway can be safeguarded, and users will get…
