What is Email Threat Protection?

Email is a popular means of communication and is also the most effective tool used for committing cyber crimes.

The more knowledge cybercriminals gain about a targeted individual or business, the more successful they’ll be in executing an email-based attack. Strategic attacks on a business often involve using personal information, obtained through accessing social media sites and simple searches on search engines, to target an individual or small group. Cybercriminals know how to combine that information with social engineering and a spoofed address to provoke a response.

Email Is the Primary Threat Vehicle

Cybercriminals are ingenious and have years of experience developing email security threats.  The vast majority rely on email as their primary threat vehicle.  There are many categories of email threats.  It’s essential to understand how they work so they can be deterred, identified, and eliminated.

Stopping the Tide of Email Threats

The best strategy for ensuring cybersecurity is a layered approach.  The same holds for email threat prevention. Advanced email threat protection begins with a lightweight inspection, including header checks, sender filtering, and source validation.

URL filtering and Brand Protection

  • DKIM – Domain Keys Identified Mail is a method used to detect false sender addresses often associated with phishing and spam.  DKIM also checks that an email from a specific domain is authorized by the owner of that domain.
  • SPF – Sender Policy Framework is an email authentication method that specifies the mail servers authorized to send emails for the organization’s domain.  It is used to prevent spammers from illegally sending messages on behalf of a business.
  • DMARC – Domain-based Message Authentication, Reporting & Conformance is an email authentication protocol.  It gives email domain owners the ability to protect their domain from unauthorized use.
