Description: File system permissions determine who can access and modify files on an operating system. These permissions are fundamental for data security and integrity, as they allow control over access to files and directories. In Unix-based systems, permissions are managed through a model that includes three types of users: the file owner, the group to which the file belongs, and other users. Each of these groups can have different levels of access, including read, write, and execute permissions. Proper configuration of these permissions is essential to protect sensitive information and prevent unauthorized access. Additionally, permissions can be modified using specific commands in the terminal, allowing system administrators to adjust access as needed. In summary, file system permissions are a key feature that ensures security and control over data in various computing environments.
