Lecture
This lecture covers the implementation of access control in Linux and Windows through the Discretionary Access Control approach. It discusses the principles, objects, and mechanisms used by both operating systems to adhere to security principles. Topics include Unix user identities and groups, file access control lists, special users, super users, special rights like suid/sgid and sticky bit, and an overview of Windows' discretionary access control lists (DACL) with access control entries (ACEs).
