Permissions
Systems · Beginner
Rules that state which identities may read, change, or execute a resource. They are enforced by the operating system, a directory, or an application.
They are the practical form of authorization. A file, a share, and a cloud bucket can each have their own rules, and the most specific enforcement wins only if you know which layer you are looking at.
Example: A folder grants the finance group read access and denies everyone else. A user outside that group cannot open the files.
Common misconception
- Being able to see a shared folder's name is not the same as having permission to open the files inside it.
