Role Based Access Control (RBAC)

Formal user access control procedures must be documented, implemented and kept up to date for each application and information system to ensure authorised user access and to prevent unauthorised access. They must cover all stages of the lifecycle of user access, from the initial registration of new users to the final de-registration of users who no longer require access. These must be agreed by IDI. User access rights must be reviewed at regular intervals to ensure that the appropriate rights are still allocated. System administration accounts must only be provided to users that are required to perform system administration tasks.

When deciding how to grant access to users, the main concept is limiting access. Users should be granted only based on level of permissions they need in order to perform their job duties. By placing users into groups according to their job titles in an organization, this will provide these users access to company information and resources in the network. These group assignments will allow an organization to give users only what they need to complete their job tasks and ensure that unauthorized access is limited.

Access refers to the inflow or exchange of information between a subject(person) and a resource which could be a system, it could also be seen as the unrestricted activity an individual is allowed to perform within any given scenario or environment.

Access control refers to the mechanisms that identify who can and cannot access a network, resource, application, specific action.

Mandatory access control is a single user, normally the network admin, who is given access to the users’ rights and privileges. They control access policies and are also in control of choosing which objects and what systems each individual user has access to and what they do not have access to. The access is made in the form of different levels. Each system and all folders containing information are put into a specific classification. The user will be in a certain classification that will only allow them to access data

Roles and responsibilities – It is possible that during the project development some staff may have difficulty in defining their roles within the team or were not part of the role development process that takes place during the forming stage of Tuckman’s team development model. It is also likely within the project team to have duplication of roles/function, even though Belbin’s Team roles model may have been used. However it is not a pre-requisite that all team must have the nine roles specific by Belbin. ‘Team members can take on more than one role and some roles are not necessary in certain teams’. (Horn 2009:13)

Information security is the protection of information against accidental or malicious disclosure, modification or destruction. Information is an important, valuable asset of IDI which must be managed with care. All information has a value to IDI. However, not all of this information has an equal value or requires the same level of protection. Access controls are put in place to protect information by controlling who has the rights to use different information resources and by guarding against unauthorised use. Formal procedures must control how access to information is granted and how such access is changed. This policy also mandates a standard for the creation of strong passwords, their protection and frequency of change.

Access controls, this control refers to who can access all the vital information about the business, its assets which include inventory, land and building, its liabilities like bills, credits and rent and equities. This information is kept

Access control has been in use before the growth of the technology world. It could involve a simple action as locking a door. A person locks a door to prevent entry to those who are not allowed or authorize to do so. The same can be said about the security involving databases and the controlling of who can have access and what can be accessed. As far as database security is concerned, there are various categories that are involved in access control. The four main categories of access control include: Discretionary, Mandatory, Role-based, and Rule-based access control.

Confidentiality: Access controls help ensure that only authorized subjects can access objects. When unauthorized entities are able to access systems or data, it results in a loss of confidentiality.

Access control: The ability to permit or deny the use of an object (a passive entity such as a system or file) by a subject (an active entity such as a person or process).
