below mention is the question of Information security

You have just been hired as the new Network level guy. The boss called you up on day 1 and said; send this package to Mr. XYZ. Make sure that NO one removes anything from this package or add to it. What are you going to do? You are completely new to this level security. Oh and by the way, the boss said, remember that when you are delivering this package, the guard at the gate of the office definitely wants to know about the label of the contents of the package and may want to modify it.
