Here is my personal list of suggestions to protect yourself online, based on my reading since getting hacked two weeks ago.
- Never respond to a website, email address or phone number that appears in a pop-up box on your computer! This was my big mistake. Call a computer technician.
- Consider carefully how much information you give out online. I have chosen to write a blog, so you can find my picture and probably my name online easily, but that is my choice. Because so many places ask for my birthdate in a medical context, I tends to assume that is public too. At the other extreme I would never give out my social insurance number or Passport identification to just anyone, and I am pretty careful about my address too.
- Consider carefully whether to post pictures of relatives including grandchildren. I no longer do.
- Have a second credit card with a low limit for online purchases. If that one is not through a different financial institution, consider a third credit card through a different institution especially for international travel. We had a card compromised while in Europe once and without a card from a different bank would have had a serious problem. For the scammed card they were spending the money within two hours, using a replica card in Indonesia!
- Have strong passwords with a mix of capitals, lowercase letters, numbers and symbols - a minimum of ten digits long. Make them phrases you can remember but no one else will guess, do not write them down, memorize them and do not share them with anyone!
- Do not use public Wifi such as in a library to access bank accounts.
- Watch for suspicious emails and do not fall for phishing, which might ask you to click on a link in an email. Do not respond to an email from anyone you do not know, or click on any attachment on such emails.
- Keep your computer up-to-date, and install antivirus software, antispyware software, and a firewall. Get professional help if you need to, which I will do.
- For places that have it available, use two-step authentication, for example when you get a code sent by text to complete your sign-in.
- If shopping or paying for services online only give out credit card information to companies or agencies you trust.
- Monitor your accounts and, if you are really concerned, your credit score (you may need to pay for this). There are two sides to monitoring your accounts. I have had it recommended by bankers that I do get online banking (which I have), so I can check for unknown expenditures regularly. Other people I know are uncomfortable with online banking because it exposes you through your own computer rather than only the bank. Your choice.
Hope you find these suggestions helpful. Coming up - some fall colour.
