Introduction to Linux

# History of Linux In 1991, while studying computer science at the University of Helsinki, Linus Torvalds began a project that later became the Linux kernel. He wrote the program specifically for the hardware he was using and independent of an operating system because he wanted to use the functions of his new PC with an 80386 processor. Development was done on MINIX using the GNU C Compiler. In order to facilitate development, the files were uploaded to the [FTP server](https://ftp.funet.fi/) of FUNET in September 1991. Ari Lemmke at Helsinki University of Technology (HUT), who was one of the volunteer administrators for the FTP server at the time, named the project "Linux" on the server without consulting Torvalds.

Authentication & Authorization

# AUTHENTICATION A user authentication policy is a process in which you verify that someone who is attempting to access services and applications is who they claim to be. This can be accomplished through a variety of authentication methods, such as entering a password into your laptop or phone or a PIN number into the ATM. **What is the purpose of authentication?** Authentication is used to verify that you are who you say you are. After a user’s identity is confirmed, for instance with a username and password, that identity may be used in an authorization policy to determine the appropriate access privileges. Organizations today must ensure that the right users are given access to the right resources, whether it is physical or--increasingly--digital.
