What is encryption?

• A process that converts original information,
  also called plain text into a difficult-to-interpr
  et form called ciphertext.

• Done by using an encryption algorithm, a formula
  used to turn plain text into ciphertext.

• Two types Asymmetric and Symmetric

Which one is better?

• Although, symmetric encryption is fast, it is not
  as safe as asymmetric encryption because someone
  could steal the key and decode the messages.
  But because of its speed, it's commonly used for
  e-commerce transactions.

• Asymmetric encryption is more complex--and more
  secure. Asymmetric encryption's added safety
  comes at a price More computation is required,
  so the process takes longer.

Whos using encryption?

• If you use a computer and the internet, youre
  using encryption!

• Enables all organizations regardless of their
  size, to be both user-and-IT friendly.

Why use encryption?

• Authentication
• Protects personal data such as passwords.

• Privacy
• Provides for confidentiality of private
  information.

• Integrity
• Ensures that a document or file has not been
  altered.

• Accountability
• Prevents denial or plagiarism.

8
How do you manage encryption?

• Make sure the encryption system has a complete
  key management application.
• This will help manage and protect the data and
  keys, and help you safely match encrypted data
  with the right key.

Examples of Encryption

• Web browser encryption

• Email encryption

• Hard drive encryption

• Operating system protection

How prevalent is it?

• According to InformationWeek Research

• Of 500 sites surveyed, two-thirds report using
  encryption to protect company data.

• Of 500 companies surveyed, 43 use encryption on
  both stored and transmitted data. More than three
  out of five companies encrypt due to the threat
  of outsiders intercepting sensitive data.

• Of 28 of sites surveyed, government regulation
  requires encryption of stored and transmitted
  data.

• For 38 of companies, the complexity of the
  technology is an obstacle.

• Some businesses arent able to use the technology
  because of the lack of skilled IT personnel and
  budget limitations.
