12 Safety Tips - 1
  • General
  • Turn off (or disconnect) the computer when you're
    not using it, especially if you have an "always
    on" Internet connection.

13
12 Safety Tips - 2
  • Laptop security
  • Keep your laptop with you at all times when not
    at home. Regularly purge unneeded data files
    from your laptop.
  • PDAs
  • People tend to store more personal data
    (including passwords and PINs) on PDAs than they
    do on laptops. Be smart!

14
12 Safety Tips - 3
  • Backups
  • Back up regularly. Back up to disk, tape or
    CD-ROM
  • Store at least one set of backups off-site (a
    safe-deposit box is a good place) and at least
    one set on-site.
  • Remember to destroy old backups. One way to
    destroy CDs is to microwave them on high for five
    seconds. You can also break them in half or run
    them through better shredders.

15
12 Safety Tips - 4
  • Operating systems
  • Consider Macintosh or Linux.
  • In Windows, set up Automatic Update so that you
    automatically receive security patches
  • Delete, rename, or move the files "command.com"
    and "cmd.exe."

16
12 Safety Tips - 5
  • Applications
  • Limit the number of applications on your machine.
    If you don't need it, don't install it. If you no
    longer need it, uninstall it.
  • Regularly check for updates to the applications
    you use and install them.

17
12 Safety Tips - 6
  • Browsing
  • Limit your use of MS Internet Explorer.
  • Limit use of cookies and applets to those few
    sites that provide services you need. Set your
    browser to regularly delete cookies.
  • Don't assume a Web site is what it claims to be,
    unless you've typed in the URL yourself.
  • Make sure the address bar shows the exact
    address, not a near-miss.

18
12 Safety Tips - 7
  • Web sites
  • Secure Sockets Layer (SSL) encryption does not
    provide any assurance that the vendor is
    trustworthy or that its database of customer
    information is secure.
  • Limit the financial and personal data you send to
    Web sites. If you don't want to give out personal
    information, lie.
  • Opt out of marketing notices.
  • If the Web site gives you the option of not
    storing your information for later use, take it.
  • Use a credit card for online purchases, not a
    debit card.

19
12 Safety Tips - 8
  • Passwords
  • For high-security Web sites such as banks, create
    long random passwords and write them down. Guard
    them as you would your cash.
  • Never reuse a password for something you care
    about. (It's fine to have a single password for
    low-security sites, such as for newspaper archive
    access.)
  • Never type a password you care about, such as for
    a bank account, into a non-SSL encrypted page.

20
12 Safety Tips - 9
  • E-mail
  • Turn off HTML e-mail.
  • Don't automatically assume that any e-mail is
    from the "From" address.
  • Delete spam without reading it. Don't open
    messages with file attachments, unless you know
    what they contain immediately delete them.
  • Never click links in e-mail unless you're sure
    about the e-mail copy and paste the link into
    your browser instead.
  • If you use Microsoft Office, enable macro virus
    protection in Office 2000, turn the security
    level to "high" and don't trust any received
    files unless you have to.
  • If you're using Windows, turn off the "hide file
    extensions for known file types" option it lets
    Trojan horses masquerade as other types of files.
  • Uninstall the Windows Scripting Host, or, if you
    can get along without it, change your file
    associations so that script files aren't
    automatically sent to the Scripting Host if you
    double-click them.

21
12 Safety Tips - 10
  • Antivirus and anti-spyware software
  • Use it--either a combined program or two
    separate programs. Download and install the
    updates, at least weekly and whenever you read
    about a new virus in the news. Some antivirus
    products automatically check for updates. Enable
    that feature and set it to "daily."

22
12 Safety Tips - 11
  • Firewall
  • Spend 50 for a Network Address Translator
    firewall device it's likely to be good enough in
    default mode. On your laptop, use personal
    firewall software. If you can, hide your IP
    address.

23
12 Safety Tips - 12
  • Encryption
  • Install an e-mail and file encryptor (like PGP).
    Encrypting all your e-mail or your entire hard
    drive is unrealistic, but some mail is too
    sensitive to send in the clear. Similarly, some
    files on your hard drive are too sensitive to
    leave unencrypted.
