Why would you want to set file permissions?
What will be an ideal response?
Early in computing, people didn't worry much about security. Stolen files and intrusions were less of a concern, in part because networks were rare and there was no Internet. As you have probably learned through the media, friends, and school, times are different and you need to protect your files. Security is important on UNIX/Linux systems because they can house multiple users and are connected to networks and the Internet, all potential sources of intrusion.
Users can set permissions for files (including directories) they own so as to establish security. System administrators also set permissions to protect system and shared files. Permissions manage who can read, write, or execute files.
