Email is simply not secure. Messages are not secure in transit: the protocol used for sending email (SMTP) does not require encrypted connections, so it could easily be intercepted by a third party as travels over the internet. You also have no guarantees about the security of a recipientâ€™s email client or server. A hacker could have surreptitious access to a recipientâ€™s inbox, or curious IT guy could be reading through email on the server.
Is there an alternative? I’m not so sure. I think one way to limit exposure to security-related risks is to limit how much we write in our emails.
