Cyber Security Awareness Poster
When a letter (email) leaves your computer [1], it is placed in an envelope (encrypted with TLS or transport layer security).
When it arrives at a poist office [2] (your ISP or internet service providor) the letter’s envelope is taken off and copes are left behind. The post office (ISP) then puts your letter back in an envelope (TLS) and sends it to the receiving post office [3] (ISP) where the envelope is reomved and more copies of the letter are made.
When your letter (email) arrives at its final location the envelope is removed by the computer’s settings [4] for the user to view [5].
