Access control

Role base access control (RBAC) can be defined as granting access to computer resources and network resources to individuals based on the roles they play in an enterprise. For example in a hospital setting which comprises of doctor, nurses, pharmacists, this users do play roles in the hospital setting and they are granted privileges based on the role they play in the hospital. Doctors could be granted privileges to write out prescriptions, modify prescriptions. A pharmacists will be granted permission to dispense prescriptions but not to write out prescriptions. The application of this model is apparent in commercial data management systems and it is widely used due to the papers written by Baldwin describing a database system using role…

handled or even shared through electronic stems. The HIPPA rule has led to the establishment of standards that are widely followed in the organizations so as to ensure that there is security and control of patient data. The paper lays a focus on important aspects of the HIPAA rule. The importance of access controls in addition to audit controls Audit controls cannot be ignored, but they are part of the control process. The audit controls documents system…

In a complex environment, the management of user access to databases and other network resources can become a daunting task. Users are dynamic, with changing privileges, and role based access controls (RBAC) are a powerful way to both organize permissions into groups, and therefore ease user administration. Importantly, technical employees such as database administrators, are then able to dedicate more time to troubleshooting security issues and organizing the system than to micromanaging the…

The decision to implement a converged technology within an organisation should be a conscious decision, however, with wireless there exists a very real threat of unauthorised implementations. This ultimately creates a risk to the information assets within an organisation, even when there is no perceived threat. So in the security policy the organisation can state its stance upon the installation of wireless access points, in that at the very least they must have prior authorisation and adhere to…

Weaker boundaries between industrial control systems and enterprise networks makes it difficult to detect unauthorized activity in critical systems. 2. Least functionality: It is important for organizations to minimize and close unused services, ports, protocols, applications and functions that increases vectors for malicious party to gain access to critical systems. As unauthorized personnel could plug rogue devices into open ports or unplug an authorized device and connect to gain access to…

Part based access control gives a level of reflection with the presentation of a part between the subject and the item consent. A part is a compartment with an utilitarian significance, for instance, a particular employment inside of a venture. Authorizations to questions are appointed to parts and subjects are doled out to parts. Part individuals are allowed target authorizations connected with the role(s) in which they have a place. See Figure 1. This level of deliberation assuages the weight…
