Computer Services Tips for Safe Computing
The following recommendations should help keep your computer secured.
- Update your Operating System – most desktop security incidents are centered on flaws in
the operating system. As these flaws are discovered, vendors release patches to cover these
security holes. By updating your operating system you ensure it has all the latest patches.
Click on:
- Right-click on My Computer. This will most likely be located in the Start menu
or on your Desktop.
- Select Properties. This will bring up a Systems Properties window.
- Click on the Automatic Updates tab.
- Select Automatic (Recommended). Choose a time every day that your computer will be
on, but you will not necessarily be using it.
- Click OK.
- Create Strong, Effective Passwords – More information on passwords

- Don’t Open Unexpected Attachments
- Do not open unexpected e-mail or instant messaging attachments, even from
coworkers or other trusted sources.
- Never open attachments from an unknown or suspicious source.
- Never download freeware or shareware from the Internet unless you investigate the source.
- Disable macros on questionable documents.
The most wide-spread types of viruses spread themselves through multiple methods. One very
common and successful trick is for a virus to send itself as an email attachment using random To:
and From: addresses.
- E-mail messages sent over the Network can be read by others, including individuals
within USI.
- Never send passwords, credit card numbers, or other access information via e-mail
unless it’s encrypted.
- Remember USI owns all incoming and outgoing instant messaging and e-mail messages.
- Install and Update Antivirus Software – antivirus software with up-to-date virus definitions
(the list of viruses it can detect) is just as essential today as it has always been.
University owned desktop and laptops should have a copy of Computer Associates
ETrust, installed and configured by Computer Center personnel.
Viruses can come from:
- E-mail and instant messaging attachments.
- Infected files shared via removable storage (diskettes, CDs, Zip disks, and other
media) or over the network.
- Worms written to take advantage of unpatched systems.
- Software downloaded from the Internet.
- Wireless connections
- How to Get Rid of Spyware? – The university recommends two spyware removal tools,
which can be downloaded for free. The free tools are Ad-Aware and Spybot-Search and Destroy.
These programs search your hard drive to find any instance of known spyware activity and also
have the capability to remove these instances. Often one program will find instances of spyware
that the other may miss so it is recommended that both programs be run in conjunction to eliminate
as much spyware from your system as possible.
Spyware Downloads:
- Lavasoft Ad-Aware - http://www.lavasoft.de/
- Spybot Search and Destroy - http://www.spybot.com
- Microsoft Windows Defender - http://www.microsoft.com
- Install a Personal firewall – Windows XP has a built-in firewall that works well
to protect your computer. Make sure you have your firewall turned ON in Windows XP.
- Click Start, and then click Control Panel. (make sure you’re in classic view)
- Click Windows Firewall
- Click ON
- E-mail and Instant Messaging – Don’t assume that your E-mail will be read only by the
intended recipients. Think of E-mail as you’d think of a postcard. No one writes confidential
or sensitive information on a postcard, because it offers no privacy. E-mail is similar. Your
messages sometime won’t get to your intended recipients due to delivery problems or invalid
addresses. Messages sent over a wireless network are essentially broadcast and can be intercepted.
If you have sensitive information to share by E-mail, your best bet is to use encryption to both
protect the contents of your message and to prove to the recipient that the message was sent by you.
Remember:
- E-mail represents our single biggest security concern.
- Viruses are most commonly spread through e-mail attachments.
- Viruses can also be sent through instant messaging attachments.
- Confidential information can be accidentally and/or purposefully compromised through
both e-mail and instant messaging.
- Report Computer Security Issues and Viruses to the Help Desk 465-1080
Remember:
- SPAM and Computer Scams
There are multiple reasons for SPAM:
- There is a lot more spam being sent (more than 50% of incoming USI email is SPAM)-40+% is
deleted before reaching your inbox.
- Don’t use your usi.edu email address when filling out web forms (where a web page asks your
name, address, and email address)
- Don’t open email messages that are sure to be SPAM. Some spammers use a technique where
they are alerted when their message is read which pieces are opened (not replied to-but opened). They
will send active mailboxes more mail and even sell your address to other spammers.
- Don’t publicize your email address on web pages. There are tools that spammers use to scan web
pages looking for MailTo links.
- Be careful how you post to mailing lists, chat rooms, or newsgroups. Posting (not subscribing)
makes your address vulnerable and available for harvesting. If you don’t mind possibly receiving spam
mail, post anyway. But if you do mind, use personal email to correspond directly with the person to whom
you are responding. For chat rooms or newsgroups, you can also correspond directly with one of the
frequent posters, or with the moderator, if there is one.
- What Can YOU Do to Save Yourself the Aggravation of Dealing with SPAM?
- Create an Outlook RULE to move messages that are spam, or thought to be spam, to a folder
and review this folder on a periodic basis. Follow these steps in Outlook:
CLICK ON:
Tools, RULES & Alerts, New Rule
Start from Blank Rule,
Check messages when they arrive, Next
Check the box that says: Specific words in Subject or Body
In lower pane click on “specific Words”
Type in “***SPAM***” click ADD… if you have more words you want to
block, add them
Click OK and NEXT
Check “Move it to the specified folder”
In lower pane-click “specified”
Choose the Junk mail folder
Click OK,
Click Next 2 times
Name the Filter: SPAM
Click finish
