 | Do not open email attachments you are not expecting, even if they come
from a trusted source.
 | One of the characteristics of many email viruses is that they can
forge the name in the From field. That means you cannot trust that an
email is from whom it says.
|
|
| Delete suspicious emails without opening them.
| Some viruses have the capability to run dangerous code on your
computer if you simply open the email without opening any attachments.
Be especially wary of messages that seem legitimate but are out of
context or are otherwise confusing. Some viruses will forward old
messages from someone's Inbox to another user.
|
|
| Set your Outlook to use AutoPreview instead of the Preview Pane (Select
View, AutoPreview to turn it on and View, Preview Pane to turn that
off.)
| The Preview Pane will allow dangerous code from an email to run
without actually opening the email message. AutoPreview, on the
other hand, does not carry that same risk but will show you the first 3
lines of an email message so you have some information to help you
decide which messages are safe to open.
|
|
| If you receive an unexpected attachment from someone you do not know,
delete the e-mail without opening the attachment.
|
| If you receive an attachment from someone you do know (a client, friend or
co-worker) but were not expecting an attachment from them, either email back
or telephone the sender to make sure they sent the attachment intentionally
before you open it.
| IMPORTANT: This rule applies to
attachments received from in-house (KTC employees) as well as those
received from outside our system. If a KTC employee gets a virus their
e-mail account could proliferate it by sending it around to everyone in
their address book, and that includes everyone in KTC Global. Just
because you receive the attachment from a co-worker does not mean it is
safe. Follow the same rules for unexpected attachments above.
|
|
| Even if you are expecting an attachment, take a close look at the file
extension before you open it. When you double click an attachment, you will
get an Opening Mail Attachment dialog box. At the top of the box it will say
Opening: plus the file name. If the file name ends with something other than
.DOC, .XLS, .PPT, .JPG, .GIF, or .PTX please check with someone in the IS
Department before opening the attachment.
|
| Protect your home computer. Make sure you are running anti-virus software and that
you have a current pattern file for it. See the Home
Computer Security section for more information.
|
| Please contact someone in the IS Department immediately if you try to open
an email or attachment and it opens a program which you did not intend to
run.
|
| Viruses can forge the From and Re lines of an email message. If you
receive a message from a system administrator saying that you sent a virus
but you didn't even send an email, just delete the message. That is a
symptom of a virus, but one that has infected some other computer with your
email address on it - not yours.
|
| If you receive a confusing or "junk" email please do not email
back the person who appeared to send it to you, because that person is
probably not the person who is infected. It could have come from anyone.
Simply delete the message.
|
| If you hear of a new virus whether your information source is via e-mail,
the web, or news media, please notify the IS Department (KTC Nettech on
e-mail) immediately so the information can be checked out and disseminated
if appropriate. Please do not send the information out to the
KTC Global address list yourself.
|
| If you have a visitor such as a client or friend who needs to use Internet
access, please do not allow them to use the login on your own
computer. Visitors do not have the same computer security education as our employees. Please invite visitors to use the Internet kiosk
in the 29 Main lobby area instead. That workstation is connected to
the Internet but is not connected to our network and is a much safer method
for visitor surfing.
|
| Don't check your personal email (such as Yahoo, Hotmail or AOL) from the
office. It is not scanned by Erado or our virus software.
|
| Change your password often and make it a good one.
