This month’s Security Awareness Reminder (SAR) is related to the receipt of emails from unknown senders.
When receiving email from unknown senders,
one should take note, especially if the received
email contains links or attachments.
These links and attachments could
contain harmful programs that could
compromise the security and privacy
of your computer system.
Given the risk of compromising
Suggested SAR text
the privacy and security by intro-
ducing a harmful program onto the
organization’s computer system, the following
reminder is provided for your consideration
“When receiving an email, take a moment to
identify the sender of that email. If the sender
is unknown to you and the email contains
links or attachments, please take a moment to
validate the sender, the reason for the email,
and the nature of the links and attachments.
These quick and easy steps can significantly
help maintain the privacy and security of our
network by reducing the risk associated with
clicking on links and opening attachments
from unknown senders of emails.”
Why this reminder matters
The use of email is very popular and often the
communication channel of choice between
people. Instead of calling a person by phone,
most people opt to send that person an email.
Consequently, it is very common for people to
get quite a few emails during the day. Unless a
person makes the effort to review their email
box regularly, a person can easily end up with
several dozen emails stacked up in the inbox
waiting for attention. This in turn may prompt
people to go through their emails with little
thought as to their origin in the effort to clean
up their inbox.
One strategy that is used by hackers to try
to compromise an organization’s computer
system is to send emails that people may
not recognize as coming from an unknown
sender, hoping a recipient will then click on a
link or on an attachment that ends up creating
a computer security incident.
Understanding how this method of
attack makes use of email and the tendency
that people have to go quickly through their
emails, the stage is set for a successful attack
on a computer system by someone clicking on
a link or attachment that was sent by a computer hacker.
By raising awareness of this ever-present
threat of an email-based attack, advising
people to exercise care in the review of emails,
and providing guidance on what users are
to do when they receive a suspicious email,
organizations can increase their chances of
preventing a computer security incident.
