CHAPTER SUMMARY

In this chapter, you read about how access controls are implemented in various operating systems and how those security features are used to solve real-world challenges. The goal of any access control system in a server or network environment is to decide whether any given user can access data and what they can do with it. To achieve this goal, operating systems implement a system of granular user rights. Users are bundled into groups to simplify rights management.
