Question

What type of control scheme is used for the Linux filesystem?
Group of answer choices

DAC

MAC

RBAC

ABAC

Answer 1

The Linux filesystem primarily uses **DAC (Discretionary Access Control)**. In DAC, the owner of a file or directory has the discretion to determine who can access or modify it. Each file has an owner and associated permissions that specify what different users can do with the file (read, write, execute). While Linux also supports other models like MAC (Mandatory Access Control) through various security modules (like SELinux), the default and most common scheme is DAC.
