Protection is a technique for protecting data and processes from harmful or intentional infiltration.

Although, these policies are modified at any time. It is the responsibility of both the operating system designer and the app programmer.

The policies define how processes access the computer system's resources, such as the CPU, memory, software, and even the operating system.

Various goals of protection in the operating system are as follows:

Its purpose is to ensure that only the systems' policies access programs, resources, and data.

It is important to ensure no access rights' breaches, no viruses, no unauthorized access to the existing data.

It helps to ensure data security, process security, and program security against unauthorized user access or program access.

There may be security risks like unauthorized reading, writing, modification, or preventing the system from working effectively for authorized users.

Various needs of protection in the operating system are as follows: It is critical to secure the device from unauthorized access, viruses, worms, and other malware. Protection may be achieved by maintaining confidentiality, honesty and availability in the OS. Users should take protective measures as a helper to multiprogramming OS so that multiple users may safely use a common logical namespace like a directory or data. It needs the protection of computer resources like the software, memory, processor, etc. You may utilize protection as a tool for multi-programming operating systems, allowing multiple users to safely share a common logical namespace, including a directory or files. What is Protection in Operating System?ДЄ mechanism that controls the access of programs, processes, or users to the resources defined by a computer system is referred to as protection. In this article, you will learn the protection in the operating system with its needs, goals, and authentication. The operating system grants different 'access rights' to different subjects. In a multiuser environment, all assets that require protection are classified as objects, and those that wish to access these objects are referred to as subjects.

It is the operating system's responsibility to offer a mechanism that protects each process from other processes. Protection is especially important in a multiuser environment when multiple users use computer resources such as CPU, memory, etc. Next в†’ в†ђ prev Protection in Operating System
