When accessing a file in a shared folder, which permissions take precedence?

When accessing a file in a shared folder, the principle of least privilege applies, where the most restrictive permissions govern access. This means that if a user has both read and write access to one folder but only read access to another, the permissions from the more restrictive folder will take precedence when accessing a file that is shared across these folders.

This is crucial in ensuring that access control is maintained, and users do not gain broader privileges than intended. The most restrictive permission effectively limits what actions a user can take, safeguarding sensitive data and helping to enforce security policies. Adhering to this model prevents unintended modifications or exposure of data by restricting actions to only what is permitted by the tightest security policy in effect for that particular file or folder.
