Access Control and Business Intelligence
Access Control
Access control is a concept widely used in the field of security, be it physical security or information security. The idea is to restrict unauthorized access to a place or resources. An example of an access control device is the hand geometry scanner. The hand scanner can either grant the request of allowing a person on-premises or a system or deny the request. A security policy sets up a mechanism that implements the regulations that enforce the decisions made by the device, allowing in or denying. There are three main concepts explaining access control. The first one is the Security Policy, which defines the rules regulating access control. Second, the Security Model provides formal information on the access control security policy and operation. The third concept is the Security Mechanism. Security Mechanism explains the basic functionalities of the software and hardware that carry out the controls stipulated in the model (Samarati & de Vimercati, 2000).
Business Intelligence
Business intelligence consists of a plan of actions and technologies used in companies and businesses for analyzing data and business information. Business intelligence systems often use operational data and analytical tools to provide information to the managerial team, who are the decision-makers of an enterprise (Negash & Gray, 2018). The systems gather data, store it, manages the knowledge, and analyses it before giving feedback. The feedback provided as information is vital as it may assist in discovering new potential areas in the firm, current trends, and future direction in the market. Business intelligence systems also ensure that the information is provided at the appropriate time and location, and also in the right format. And this helps in improving the timeline and excellence of the decision-making process. Data mining is one of the essential components contributing to an effective business intelligence system. Through data mining, business intelligence can handle huge proportions of structured and unstructured data to help discover, create, and implement new business ventures. Mainly business intelligence aids in strategic and operational decision making.
