2.           The elimination of the pain that comes with data breach disclosures.
3.           The provision of strong protection for intellectual property.

• Disadvantages

1.          The security of data becomes the security of the encryption key. 
2.          Encrypting data and creating the keys necessary to encrypt and decrypt the data is computationally expensive.

FIREWALL

• What is Firewall?

                      A firewall is either a type of software or physical device that sits between a computer and the       internet. Its purpose is to regulate the Internet connection, allowing certain traffic to enter and exit the computer while keeping other certain connections from doing the same. It accomplishes this by either analyzing every bit of data sent and received from a computer, regulating programs or acting as a proxy server, meaning that all traffic is sent through another server before it reaches its destination.
