Which concept describes the practice of limiting access to resources based on user permissions?

• A. OS Types
• B. Access Control
• C. Web-Browsing Software
• D. Remote Support Software

Answer: (B)

Access control is the practice of restricting access to resources based on permissions assigned to users. It ensures that only authenticated and authorized individuals can interact with files, systems, or networks by evaluating who the user is and what they’re allowed to do. Implementations like access control lists, role-based access control, or attribute-based access control, along with principles such as least privilege, help enforce these limits. This protection is essential for maintaining confidentiality and integrity. The other options refer to broader categories that don’t describe limiting access. Operating system types are different families of systems, not a method for controlling who can access resources. Web-browsing software is a tool for accessing websites, not a mechanism for enforcing access permissions. Remote support software facilitates assistance remotely, but it doesn’t govern access to resources based on user permissions.
