In the field of computer and information security, access control is the process of managing policies that grant rights (also called privileges) to subjects in relation to objects. A policy tuple is a formal description of a policy, typically written as 〈s,o,r〉, where s is a subject, o is an object, and r is a right. For example, a policy may give a user named Alice, who is a member of a company's sales team, the ability to read the customer list file. In this case, the policy tuple would be written as 〈Alice, customer list, read〉. Another policy tuple, 〈Bob, customer list, write〉, may indicate that Bob, as a sales manager, has the ability to write or modify the customer list.
