how to create user group and sign the permission of a folder to a user

[searain]

1) in pc, i can create a user on the NT server and then assign the access to certain folder to this user only.

2) and then i can go the the IIS manager, to set this folder access with the password checking.

so only the user with the access to this folder can access it through the HTTP.

how can i do it in Linux?

limit the HTTP access of a folder to certain user?

thanks
