Q. I use sudo to provide permissions and command execution rights to other users under UNIX and Linux operating systems. However, I noticed something strange about sudo. When executing sudo, it will prompt for the user’s password the first time, but sudo no longer requires a password anymore when re-executing it. Why? Is this is a security risk?
