This Cyber “stuff”…

Affects us all!Each unprotected/unpatched computer is a threat: Infected worm/virus/bot Could be used in a concerted attack against a critical infrastructure

Computers, servers, mobile storage devices with any sensitive information represent a vulnerability

22

What Do We Do?

Practice safe computing!

23

Keep Your Computers Safe

Update the software on your computer weekly (or more frequently)

Install anti-virus and anti-spyware software and keep it up-to-date

Use accounts and strong passwords Encrypt sensitive information

http://www.hawaii.edu/askus/729

Don’t install unknown software from unknown sites

Don’t share your accounts/passwords Use password protected screen savers 24

Use STRONG Passwords

Not easily guessableDo not use dictionary wordsUse a combination of upper and lowercase letters, numbers, and special characters

No less than 8 characters Check your password strength:

https://www.microsoft.com/protect/fraud/passwords/checker.aspx

25

Password Strategies

Replace letters with numbers or characters

Incorporate something memorable to youExample:

need password for CitiBank online account got your mortgage in April 2005: 04C7t7B@nk05

Use a phrase and turn it into a password

Example: My Favorite Food is Chocolate Ice Cream MfFiCiC2010m@r

26

More on Passwords

Don’t use the same password for all accounts

Change passwords frequentlyUse more difficult passwords on more sensitive accounts

Use a password safe (but don’t lose the master password!)

27

Protect Yourself and Information Don’t open unknown emails & attachments Visit only reputable web sites http://safeweb.norton.com/

Do not reply to SPAM or Phishing emails Only login to servers for the duration needed - disconnect when done

Don’t let others use your computer irresponsibly

Use a credit card for online shopping http://www.hawaii.edu/askus/729

28

DO NOT EVER…

…Give out your personal information in response to an UNSOLICTED email, phone call, voice mail

If in doubt, CHECK IT OUT! Call the company using another legitimate phone number (not the one provided in the email or phone call)

New scams use social networking sites to get background personal information

29

Protect Your Sensitive InformationBE SUSPICIOUS!You can’t take back information you’ve already given out

Ask “Why?” when someone asks for your SSN

Check your credit report:www.annualcreditreport.com

30

Social Networking

Do not post TOO MUCH INFORMATION!Internet is FOREVER!

Whatever you post may circulate even AFTER you delete it

New scams use social networking sites to get background personal information

Watch what your children do on the computer

31

TTMI…
