Information Classification, Identification, Authentication, Authorization
Information Security
Information Classification
Information classification involves categorizing information based on its sensitivity and the impact that unauthorized access would have on an organization. Common classification levels include public, internal, confidential, and restricted. The goal is to ensure that appropriate security controls are applied based on the classification.
Identification
Identification is the process of recognizing an entity, such as a user or a device, in a system. It involves gathering unique information that distinguishes one entity from another, typically through usernames or user IDs. Identification is the first step in establishing accountability within security systems.
Authentication
Authentication is the process of verifying the identity of an entity after identification. This can involve multiple factors, such as something the user knows (password), something the user has (security token), or something the user is (biometric verification). The goal of authentication is to ensure that the entity is who they claim to be.
Authorization
Authorization occurs after authentication and determines what an authenticated entity is allowed to do within a system. This involves granting or denying access to resources and actions based on predefined policies and roles. Authorization ensures that users have the appropriate permissions to protect sensitive information.
