Follow best practices to protect yourself online

Here are some handy tips to protect yourself:

  • Create secure passwords to keep your identity safe.
  • Remember that YOU decide what information about yourself to reveal, when, why, and to whom: Don't give out personally-identifiable information too easily; set your privacy settings in your social networking account; beware of sites that offer some sort of reward or prize in exchange for your contact information or other personal details.
  • Only download Firefox (and other software) from legitimate channels: Beware of scams such as fake Firefox updates. Only download Firefox from the official Mozilla website.
  • Be conscious of Internet security: Never submit a credit card number or other highly sensitive personal information without first making sure your connection is secure; be on the lookout for "spyware"; use secure passwords and protect them with a Primary Password.
  • Keep a "clean" e-mail address: Use some pseudonymous or simply alternate address, and keep your main or preferred address only on small, members-only lists and with known, trusted individuals.
  • Do not reply to spammers, for any reason.
  • Realize you may be monitored at work: Avoid sending highly personal e-mail to mailing lists, and keep sensitive files on your home computer.
  • Be conscious of home computer security: Turn off your computer when you are not using your Internet connection; secure your Wi-Fi network with a strong encryption (WPA or WPA2); use a firewall.
  • Examine privacy policies and seals: Does the site provide offline contact information? Does the site have a prominently-posted privacy policy? If so, what does it say? Do you have a reason to believe it? Have you ever heard of this company? What is their reputation? And are they backing up their privacy statement with a seal program? If you see a seal, is it real? Some sites allow their visitors to check these seals by clicking on them to show their authenticity.
