E-mail

Overview

Students will explore the security of e-mail, disposable e-mail accounts and use a secure e-mail system.

Purpose

E-mail is one of the most-used forms of communication. How secure are the systems that we use daily and what are the implications of insecure systems?

We will also look at alternatives that would ensure security?

Objectives

Students will be able to:

  • Identify security issues related to common e-mail systems.
  • Use a disposable, temporary e-mail system
  • Apply principles of secure e-mail through the PGP email system.

Preparation

  • Ensure the sites used in this exploration are not blocked by your school.
