As we all know. Information Technology has been affecting humans life. We no long have to queue up at banks to bank in money (Automated banking machines) replaced human. In current world, we don't even need to go to an ATM to transfer money to a third party. All we need to do is logging onto Internet Banking and pass the information to the bank server allowing it to carry out the transaction to us. How do we know if the information we passed through the Internet is safe?
Information is a precious asset. We need to protect and safeguard it unauthorized persons , keep the information intact so that it could not be changed without our permission and making the information available to authorized persons when needed.
Security of information can be threatened by security attacks. An attacker can try to read the message being passed through the Internet, the attacker could try to modify the message, impersonates somebody or repeat a message which was sent previously.
On a not so seriously note, lets me tell you a little joke about it.
There was a guy that went on a holiday and he went to the beach and saw a hot girl there, he decide to tell his wife about it.
"Honey, I went to the beach and I saw lots of hot people. Somehow I wish you are here."
Some attacker decide to attack his message and did a modification by removing the last alphabet from his message.
The message his wife received ended up to be
"Honey, I went to the beach and I saw lots of hot people. Somehow I wish you are her. "
A simple attack like this changes the whole message and this might will make things messy. =)

The example you have quoted to explain the main idea is so good that even a non technical person can easily understand the meaning. It truly depicts the use and need of security techniques.
