C'mon Stanley, think positive. You are taking the CISSP exam. ; Not the
first time, the ONLY time. ; First advice, study only the things you are
weak on. Why go over stuff already in your head. ; Take lots of
practice exams (www.cccure.org). Link encryption
occurs between any
two points directly. This happens at layer two. Only secures the
channel of communication, not the user. ; Also referred to as transport
mode. End-to-end encryption encrypts on one end and does not decrypt
till the destination. This occurs at layers 6 and 7. Secures the full
transmission, enabling full access control. Also referred to as tunnel
mode. s/MIME is used to provide confidentiality by encrypting email and
email attachments . It allows for sender authentication through
digital certificates.

Hi,
Can someone help to explain the difference between link
encryption, end to end encryption, and s/MIME?
What is the effect if only the data is encrypted and not the
header and routing infor.
I am taking the CISSP exam the first time, any advise?
Regards
Stanley
