Have you ever wonder what types of security threads you should be worried about when the times comes that you have to use a public computer for personal use? TalkTechToMe shared a list of 5 threats you should be watching out.

  1. Hardware key logger
  2. Software key logger
  3. Should surfing
  4. Network sniffer
  5. Phishing/misdirection

There are maybe more but these 5 are the most common threats from a publically used computer. And here are the rules of thumb that you should keep in mind when it comes to use a public computer in a public area.

  • Only type in the confidential information in the sites that offer an encrypted connection, meaning a SSL certificated site, to avoid the information being sniffed by the bad guy.
  • Use on-screen keyboard to enter username and password to avoid the information being key logged. There is no way for a key logger to identify a letter from a mouse click.
  • Always be cautious when entering the sensitive information, e.g. looking around before entering your password.
  • Always use private / incognito browsing when possible to not leave any footprints behind.

However, even though you followed these rules and are being very cautious, there is really no 100% guarantee that is 100% safe. The ideal of recommendation always would be never use a public computer at all.
