  5. Email can be misdirected, resulting in information being received by unintended and/or unknown recipients.
  6. Email is easier to falsify than handwritten or signed documents and it is impossible to verify the true identity of the sender, or to ensure that only the recipient can read the email once it has been sent.
  7. Email can be intercepted, altered, forwarded or used without authorization or detection.
  8. Email can be used to introduce viruses or other computer software code or routines designed to modify, erase, destroy, corrupt, disable, damage or impair other software or information into computer systems.
