Email is one of the most common forms of electronic communication for businesses, but it is also one of the most abused by malicious threat actors. For those reasons, organizations must understand how to effectively secure their email infrastructures, in addition to training their users to recognize suspicious or malicious messages.
In this course, we’ll go over why email security is critically important with some examples of how email has been abused over the years. We’ll discuss what type of email filtering systems should be in place and what they should look for.

Organizations always have data that must stay private, so we’ll take a look at encryption methods and techniques as well.
