Sunset Date: This document defines the security functionality expected to be provided by a general-purpose operating system capable of operating in a networked environment. It also provides a set of assurance components that define the minimum set to be used in an evaluation of an operating system for compliance with this Protection Profile. Part 2 of this PP defines the general approach and assurance activities required to be performed during the evaluation, thereby refining the stated assurance components. The OSPP covers general-purpose operating systems that provide a multi-user and multi-tasking environment.

Difference Between Security and Protection

Security: The security systems covers the safety of their system resources saved data, memory, disks, etc across malignant alteration, illegal access, and disparity or inconsistency. The security gives a mechanism authentication and encryption to analyze the user to permit for using the system. Security is the vital task for a corporation to provide some safety mechanism in order that no outside user will access the knowledge of the organization. Protection: protection deals with the access to the system resources. It determines that what files can be accessed or permeated by a special user.

Kernel (operating system)

The kernel is a computer program at the core of a computer's operating system that has complete control over everything in the system. On most systems, the kernel is one of the first programs loaded on startup after the bootloader. The critical code of the kernel is usually loaded into a separate area of memory, which is protected from access by application programs or other, less critical parts of the operating system. The kernel performs its tasks, such as running processes, managing hardware devices such as the hard disk , and handling interrupts, in this protected kernel space. In contrast, application programs like browsers, word processors, or audio or video players use a separate area of memory, user space. This separation prevents user data and kernel data from interfering with each other and causing instability and slowness, [1] as well as preventing malfunctioning application programs from crashing the entire operating system.

Protection and security requires that computer resources such as CPU, softwares, memory etc. This extends to the operating system as well as the data in the system. This can be done by ensuring integrity, confidentiality and availability in the operating system. The system must be protect against unauthorized access, viruses, worms etc. A threat is a program that is malicious in nature and leads to harmful effects for the system.
