firewalls

Firewalls

On or off campus, the Windows firewall should be all you need.

But it has to be on.

firewalls12
Firewalls
  • Firewalls are ‘built-in’ to packages like:
    • Norton Security Center
    • McAfee Security Center
    • Windows Live OneCare (requires special exception on the UNL ResNet.)
firewalls13
Firewalls
  • There are lots of free ‘stand alone’ firewalls available.
    • ZoneAlarm
    • OnlineArmor
    • Comodo
    • Sunbelt
    • PCTools Firewall Plus
anti spyware anti malware
Anti-Spyware/Anti-Malware
  • Windows Defender is ‘built-in’ to Windows Vista. For XP, it’s getting less useful as time goes by.
anti spyware anti malware15
Anti-Spyware/Anti-Malware
  • Many available free to download
    • SuperAntiSpyware
      • Preferences>Scanning control check two boxes
        • “Close Browsers before scanning”
        • “Terminate memory threats before quarantining”
    • SpywareBlaster
    • Spybot Search and Destroy
      • Don’t install “Tea Timer”
physical security
Physical Security
  • Keep your dorm room locked.
    • Even if you’re gone for “just a minute”.
  • Keep hold of your laptop when you’re out and about.
  • Use a ‘good’ password. With a different one for the ‘admin’ account.
passwords
Passwords
  • What’s a ‘good’ password?
    • Not your name.
    • Not your unlid number.
    • Not ‘huskers’ or ‘huskerfan’.
    • Not your birthday.
    • Not anything someone could guess.
passwords18
Passwords
  • A good password is a random string of letters, numbers and characters that you can remember easily.
best practices
Best Practices
  • Don’t open email from someone you don’t know.
  • Don’t open attachments if you’re not sure what they are and what they’ll do.
  • Keep your Browser Security level set to “Medium High”.
  • Regularly scheduled manual updates and scans.
  • Keep abreast of changes, new security tools and practices.
  • And if you get a pop-up that says something like “Exploits have been detected on your computer. Click here to download a program that will fix them.” DON’T DO IT!
phishing
Phishing
  • You might get an email from your credit card company, your bank, ebay, paypal, or someone else asking you to ‘update’ or ‘confirm’ your account information. Especially your password and/or account number. They may want you to reply to the email or will have a web link for you to click.
  • This is Phishing. They’re trying to get you to give them your account/identity.
phishing21
Phishing
  • No legitimate business does this.
    • Ebay doesn’t do this.
    • Paypal doesn’t do this.
    • Visa doesn’t do this.
    • Nobody does this.
  • Even if you think it is real, don’t reply to the email, don’t click on the link. It may say ‘paypal.com’, but probably goes to a bogus site. Contact the company by typing the correct URL into the address bar of your Browser.
what if your computer is still infected
What if your computer is still infected?
  • What do you do if your Anti-Virus or Anti-Spyware finds something that it can’t clean, can’t quarantine and can’t delete?
  • Or worse yet, if it finds them and says it has cleaned/quarantined/deleted them, but when you scan again, they’re still there?
what if your computer is still infected23
What if your computer is still infected?
  • Bring it to the folks at the ResNet office or the Computer Help Center. We can help.
  • ResNet office is in the back of the Sandoz Computer Lab. 472-3535. http://resnet.unl.edu/
  • Computer Help Center is in the 501 Building. 472-3970 http://www.unl.edu/helpdesk/
what we ve learned
What We’ve Learned
  • Don’t schedule anything after the class
  • Smaller classes are better
  • Put the details on the ResNet website for later reference
  • The class is as dynamic as keeping a computer secure.
