File Management Paper
A system that support 5000 users, and only permit 4000 of those users that can access one file. This can be accomplished in many different ways. One option is for the 4000 users placed in a specific group and then set another group access to the group already on file. In addition, the second option would be the way to go, and that is to have an access control list made up with names of all 5000 users on it. To implement sharing and protection, the system must maintain more file and directory attributes than are needed on a single-user system (Silberschatz, 2015).
There are techniques to shield and protect the systems directories, files, and folders. In many cases most IT departments will set up a file permission on the files, with certain tools to be able to check accounts security, and to make sure that every user account set up passwords in the systems. When an operating system accommodates multiple users, the issues of file sharing, file naming, and file protection becomes preeminent (Silberschatz, 2015). In addition, security properties can be the source of protecting these files. For example: Access Control List is specifically for the directory and files, and Access Control Default can only be associated with the directory. Following the pattern: when a file is in the directory and does not have access to the (ACL) it will use the rule of default for the directory. So in this case if we set up only 500 users the system can access the list and find if those 500 users are allowed to have access to the file. Many systems have multiple file systems, including volumes of a single disk or multiple volumes on multiple attached disks. In these cases the ID checking and permission matching are straightforward, once the file system are mounted (Silberschatz, 2015).
When it comes to the file permission the (ACL) can provide enough control over...
