Guide: Understanding Authorization and Access for CISSP
What is Authorization and Access?
Authorization and Access is a fundamental concept in information security, it serves as a gateway to regulate the access permissions of users within a system or network.
Why is it important?
It is crucial in maintaining the integrity, confidentiality, and availability of system resources. It helps to prevent unauthorized access, data leaks, and other security threats.
How it works?
Authorization begins when a user is authenticated. The system checks the user's access permissions against the Access Control List (ACL) or similar resources. If the permissions match, the user is granted access to the specific resources otherwise access is denied.
Exam Tips: Answering Questions on Authorization and Access
For exam questions revolving around these topics, always consider the principles of 'least privilege' and 'need to know'. Remember, the correct answer often involves granting the least amount of access necessary for a user to perform their job.
Understanding different access control models like Discretionary Access Control (DAC), Mandatory Access Control (MAC), and Role-Based Access Control (RBAC) may also come in handy in the exam.
In case questions that relate to violation of access control, think in terms of what would 'increase risk' or what would 'decrease security'.

Authorization and Access practice test
Authorization and access are mechanisms that determine the permissions granted to users after they have been successfully authenticated. Authorization refers to the assignment of specific rights, privileges, or permissions to a user based on predefined rules, roles, context, or other criteria. Access, in turn, controls users' ability to interact with resources on a system or network based on their assigned permissions. Access control mechanisms include mandatory access controls (MAC), discretionary access controls (DAC), and role-based access controls (RBAC) to manage access to resources and protect information confidentiality, integrity, and availability.
