Linux Gazette carries a regular column called Layer 8 Linux Security. [9] Layers 8, 9, and 10 are sometimes used to represent individuals, organizations, and governments for the user layer of service-oriented architectures. See OSI User Layers figure for details. User-in-the-loop is a serious concept including Layer 8 as a system-level model.
Most file systems include attributes of files and directories that control the ability of users to read, change, navigate, and execute the contents of the file system. In some cases, menu options or functions may be made visible or hidden depending on a user's permission level; this kind of user interface is referred to as permission-driven.

Sensitivity is based upon a calculation of the damage to national security that the release of the information would cause. The United States has three levels of classification: Confidential, Secret, and Top Secret. Each level of classification indicates an increasing degree of sensitivity.
There are 4 privilege levels ranging from 0 which is the most privileged, to 3 which is least privileged. Most modern operating systems use level 0 for the kernel/executive, and use level 3 for application programs. Any resource available to level n is also available to levels 0 to n, so the privilege levels are rings.
This layer manages open file table entries and per-process file descriptors. [8] It provides file access, directory operations, security and protection. [7] The virtual file system, an optional layer, supports multiple concurrent instances of physical file systems, each of which called a file system implementation. [8]

A media access control protocol data unit (MAC PDU or MPDU) is a message that is exchanged between media access control (MAC) entities in a communication system based on the layered OSI model. [ 2 ] In systems where the MPDU may be larger than the MAC service data unit (MSDU), the MPDU may include multiple MSDUs as a result of packet aggregation .
