Access Control

Access control refers to the process of allowing or restricting access of different parties to the organization’s data, applications, network, or the cloud based on the organization’s policies. There are two factors that are used to complete this task: the Access Control List (ACL) and permissions.

ACLs are lists used by routers and firewall devices to grant or deny network traffic based on a set of rules. There are two different kinds of ACLs, one for files and folders and another for incoming network traffic.

The first is implemented in a file and data access environment to control who gets access to the different types of data and also restrict what level of access they get. For example, say there are two members of the sales team (Bill, the sales manager, and Ben, the sales administrator) and two folders on the file server, one for sales data and the other for marketing data. Since Bill and Ben both work in sales, they will both be given access...
