How can you protect Western?
Ensure your system is protected
• Your system should always be protected with the latest anti-virus
software and security patches. Think of it as a seatbelt and….
Buckle up!
• Know who is responsible and can help you if the
system is not protected or has been compromised
(or locked off the network)
How can you protect Western?
Don’t download freeware at work
• It may not be as ‘free’ as you think. Spyware, malware, trojans
& keystroke loggers are often hidden within ‘freeware’.
• Remember Don’t take gifts from strangers!
• If you need additional software installed, contact your
Systems Administrator for assistance
How can you protect Western?
Don’t surf suspicious websites
• Limit your web surfing to known University or commercial
websites.
• Always X out, don’t click ‘OK’ or ‘NO’ or ‘unsubscribe’
• Practice safe and responsible surfing
How can you protect Western?
Use strong passwords
• Keep your passwords in a secure place
• Avoid common words: hackers can crack dictionary passwords
• Passwords are like underwear
– They protect privacy
– They should never be shared
– The longer, the better
How can you protect Western?
Protect the data you use
• Think before storing, publishing or sharing data
– Is the data sensitive?
– Does it need to be portable?
– Who should see it?
– How have you protected it so that only
those that should see it have access?
• Mobile data on laptops and USB keys
is at risk - Leave it, Lose it.
How can you protect YOUR information?
Recognize phishing and don’t fall for it
• Phishing can come through emails or web sites
• Phishers are getting better, scams are getting trickier to detect
• Be suspicious when personal or private information is involved
and
Don’t Get Phished
• When in doubt, ask
And let’s not forget your Home
Computer!
