Files and File Sharing
Matthew Hickey, Jennifer Arcuri · 2020
This chapter helps the people to learn about file permissions and common protocols used for the sharing of files over networks. It reviews internal networks, where people may have disparate hosts connected and needing to communicate with each other. The job of network-attached storage (NAS), or a file server, is to store files and serve them to employees or members of an organization upon request. This seemingly simple task can be carried out by a number of different protocols and implemented in various ways, all with their own interesting flaws. File permissions dictate which users on a system, or network, can access any given file and the level of control they have over that file. The chapter examines NAS hacking toolkit and looks at what the Nmap scan results for a particularly vulnerable file server might look like—one that is running a range of different file sharing services.
