Access Control


An access control system ensures that an information system meets the goals of the CIA triad.

Access control governs how subjects/principals may interact with objects.

  • Subjects are people, devices, software processes, or any other system that can request and be granted access to a resource
    • aka principal
  • Objects are the resources
    • e.g., network, server, database, app, or file
  • Subjects are assigned rights or permissions on resources
  • when implemented on a computer system or network,
    • it is a type of logical security
  • typically implemented as an identity and access management (IAM) system
