An accountant would only gain access to resources that an accountant would need on the system. Example roles are: accountants, developer, among others. This is different from groups since users can belong to multiple groups but should only be assigned to one role.
Each group has individual file permissions and each user is assigned to groups based on their work role.

Windows and Linux environments use something similar by creating ‘Groups’. This gives an individual only the access needed to do their job, since access is connected to their job. It presents an opportunity for the organization to address the principle of ‘least privilege’. RBAC, also known as a non-discretionary access control, is used when system administrators need to assign rights based on organizational roles instead of individual user accounts within an organization. This popular model is utilized by some of the most popular operating systems, like Microsoft Windows file systems. Sometimes a subject/program may only have access to read a file the security kernel makes sure no unauthorized changes occur.
The security kernel within the operating system checks the tables to determine if access is allowed. Capability tables contain rows with ‘subject’ and columns containing ‘object’. The DAC model takes advantage of using access control lists (ACLs) and capability tables. The principle behind DAC is that subjects can determine who has access to their objects. Three main types of access control systems are: Discretionary Access Control (DAC), Role Based Access Control (RBAC), and Mandatory Access Control (MAC).ĭAC is a type of access control system that assigns access rights based on rules specified by users. These controls are used to protect resources from unauthorized access and are put into place to ensure that subjects can only access objects using secure and pre-approved methods. The term ‘access control’ refers to “the control of access to system resources after a user’s account credentials and identity have been authenticated and access to the system has been granted.” Access control is used to identify a subject (user/human) and to authorize the subject to access an object (data/resource) based on the required task. Considered one of the most crucial assets in a company, access control systems hold significant value.
