Fundamentals of Access Control

Introduction to Access Control

Access control refers to the methodologies and processes used to restrict unauthorized access to systems, applications, and data. It is a crucial aspect of information security aimed at ensuring that only authorized entities (users, applications, or systems) can perform specific actions on a resource.

Why Access Control is Important:

1. Security: Prevents unauthorized access that could lead to data breaches, unauthorized data manipulation, or system misuse.
2. Privacy Compliance: Ensures adherence to privacy laws and regulations, protecting sensitive information from unauthorized disclosure.
3. Data Integrity: Maintains the accuracy and reliability of data by allowing only legitimate modifications.
4. Accountability: Facilitates logging and monitoring, tracking the actions of users, and aiding in audits and forensic analysis.

Basic Terminology:

• Subject: An entity (user, application, device) requesting access to a resource.
• Object: The resource or data being accessed.
• Access Modes: Different types of operations that can be performed on an object (e.g., read, write, execute).
• Authorization: The process of determining if a subject has the right to access an object in the requested mode.
