A brief Introduction to Email Security

This is the practice of  inspecting incoming emails and securing outgoing ones to prevent attacks from hackers.

As long as a hacker has your email address, they  can send malicious emails to coerce you into giving out critical and personal information.

 Say for example, you get an email informing you that there has been a compromise to your account and that you need to respond immediately by clicking on a provided link.This is suspicious, especially when it comes from an unknown source and  is a very easy way of targeting an unsuspectfull user.

Your email can be compromised in the following ways :

  • After downloading compromised files from the internet
  • Opening malicious links sent via email 
  • Having a weak password or using a similar password for multiple accounts.
  • Failure to update your softwares that you use on your website. 

Types of email security

Using Spam Filters

Installing spam filters can help in separating legit and malicious emails by directing them to a distinctive email inbox. By doing this, your regular email inbox does not get filled with email. You also do not miss any crucial business email.

Using Email Security tools

These are reliable email gateways, deployed either on-premises or in the cloud.They offer multi-layered protection from unwanted, malicious emails, therefore ensuring business continuity for organizations of all sizes. Your  security teams can now be assured that they can secure users from email threats and maintain email communications in the event of an outage.

Ensure that you keep email servers up to date with the latest patches to prevent any attacks that exploit software vulnerabilities.

Last but not least in case you get hacked, reset your password before notifying your contacts against clicking on any suspicious links sent to them.
