Discretionary Access Control

Discretionary Access Control (DAC) is a security method that allows the owner of a resource, like a file or document, to decide who can view or use it. The owner has the flexibility to grant or restrict access to others based on their discretion. It’s like giving a friend permission to borrow your book; you control access based on your choices. DAC is commonly used in systems where users need to share resources selectively, but it relies on individual judgment, which can sometimes lead to security risks if permissions are not carefully managed.
