Access Control Matrix
Access Control Matrix: A two-dimensional table used to implement an access control policy within a system. In this matrix, the rows represent subjects (like users or processes), and the columns represent objects (like files, directories, or devices). The intersection of a row and a column indicates the access rights that the subject has over the […]
Access Control Mechanism
Access Control Mechanism: A process or system that manages access to resources within a system by enforcing policies and rules. These mechanisms often involve elements of identification, authentication, authorization, and accountability. They are integral to maintaining the security of a system by ensuring that only properly authenticated and authorized users gain access to the resources […]
Access Control Model
Access Control Model: A framework that dictates how subjects (users or processes) access objects (resources) within a system. Common models include Discretionary Access Control (DAC), where access is granted based on user identity; Mandatory Access Control (MAC), where access is determined by comparing the labels (clearances) of the users and the data; and Role-Based Access […]
Access Control
Access Control: Refers to the systematic regulation of the ability of authenticated users to view, use, or alter resources. This procedure safeguards sensitive data from unauthorized access, protects system integrity, and prevents potential disruptions. It includes techniques such as role-based access control (RBAC), discretionary access control (DAC), and mandatory access control (MAC), which decide the […]
Access Level
Access Level: A categorization of the degree of authorization that a user has when accessing a network or system. These levels often correspond to the roles of users and determine what kind of operations they can perform on the system. For instance, a user with an administrative access level has more permissions compared to a […]
Access management lifecycle
Access management lifecycle: The set of processes and procedures for managing access to a system or network, from initial user authentication to ongoing monitoring and revoking of access. It is used in organizations to ensure the security of their networks and data and to prevent unauthorized access. Examples include implementing password policies, conducting regular audits […]
