10 Fast and Free Security Enhancements

Some precautions you can take to protect from most common threats:

1. Check Windows Update and Office Update regularly (_http://office.microsoft.com/productupdates)
; have your Office CD ready. Windows Me, 2000, and XP users can configure automatic updates.
 Click on the Automatic Updates tab in the System control panel and choose the appropriate
 options.

2. Install a personal firewall. Both SyGate (_www.sygate.com) and ZoneAlarm (_www.zonelabs.com)
 offer free versions.

3. Install a free spyware blocker. Our Editors' Choice ("Spyware," April 22) was SpyBot
Search & Destroy (_http://security.kolla.de). SpyBot is also paranoid and ruthless in hunting
 out tracking cookies.
4. Block pop-up spam messages in Windows NT, 2000, or XP by disabling the Windows Messenger
 service (this is unrelated to the instant messaging program).
Open Control Panel | Administrative Tools | Services and you'll see Messenger.
 Right-click and go to Properties. Set Start-up Type to Disabled and press the Stop button.
 Bye-bye, spam pop-ups! Any good firewall will also stop them.
5. Use strong passwords and change them periodically. Passwords should have at
least seven characters; use letters and numbers and have at least one symbol.
 A decent example would be f8izKro@l. This will make it much harder for anyone to gain access
 to your accounts.
6. If you're using Outlook or Outlook Express, use the current version or one with
the Outlook Security Update installed. The update and current versions patch numerous
 vulnerabilities.
7. Buy antivirus software and keep it up to date. If you're not willing to pay,
 try Grisoft AVG Free Edition (Grisoft Inc., w*w.grisoft.com). And doublecheck
 your AV with the free, online-only scanners available at w*w.pandasoftware.com/activescan
 and _http://housecall.trendmicro.com.
8. If you have a wireless network, turn on the security features: Use MAC filtering,
 turn off SSID broadcast, and even use WEP with the biggest key you can get. For more,
 check out our wireless section or see the expanded coverage in Your Unwired World in
our next issue.
9. Join a respectable e-mail security list, such as the one found at our own Security
Supersite at _http://security.ziffdavis.com, so that you learn about emerging threats
 quickly and can take proper precautions.
10. Be skeptical of things on the Internet. Don't assume that e-mail
 "From:" a particular person is actually from that person until you have further
reason to believe it's that person. Don't assume that an attachment is what it says it is.
 Don't give out your password to anyone, even if that person claims to be from "support."
