Deploying a multilayered defence:
an analogy
Consider how airports manage a vast and
changing mix of potential security issues.
Most take a two-pronged approach, each of
those prongs featuring multiple checks and
procedures. At Proofpoint, we take a similar
approach to securing your email. This guide
explains how our multilayered defence uses
identity control and content analysis to
protect organisations from email fraud.
emails don’t have a payload. So there’s
no attachment or URL for security tools to
detect, analyse and sandbox. With email authentication, only someone
from your company – or someone you
authorise – can send email using your domain.
The messages are socially engineered for
one sole purpose: tricking people into doing
something on the attacker’s behalf. Due
to the nature of email fraud, you need
to validate the true identity of the email
sender. If you can verify whether the email
was sent by who it says it’s from – and block
any impostors – you can stop many of these
threats outright. This stops many attacks in their tracks.
DMARC authentication allows email senders
to indicate that their messages are protected
by two popular authentication techniques.
And it tells receivers what to do if neither of
those authentication methods passes.
Identity control: who’s really sending
that email? Authentication
Email fraud can be hard to detect with
conventional cyberdefences. That’s because
it is highly targeted and sent in low volumes
aimed at specific people or job roles. These For identity control, we start with email
authentication. This step stops attackers who
try to hijack your email domain, a technique
called domain spoofing.
Proofpoint helps you to implement DMARC
authentication quickly and confidently. We
give you visibility into all the email coming
into and going out of your organisation.
With this visibility, you can authorise all
legitimate senders trying to send emails on
your behalf and block any malicious emails
spoofing your trusted domains or those of
your suppliers. n
