Answer: The goals of computer security are to protect computers and users from data theft or loss as well as damage to any part of the computer.
Explanation: Common means of achieving computer security are firewalls, anti-virus software and this can fail due to hardware problems or
weaknesses that prevent malicious attacks.
To answer this question, think of a time when you experienced any one of these.

After clicking on a link on a dodgy website, a virus was installed on my computer. My computer finally crashed, without any hope of restarting it. I lost all my data and I had to buy a new computer.

Explanation:
MAC is stand for the message authentication code and it is one of the key dependent hash function. Message authentication provide the data integrity and also the origin of data authentication.
- It basically allow the specific recipients known as the holder of the symmetric key.
- The message authentication code uses the CBC (Cipher block chaining) mode for constructing the MAC algorithm and it also uses the block cipher for the conjunction by using the CBC operations.
