My top ten security tips:
1) Change your passwords. You've had them too long, you use the same password in too many places. Somewhere someone has hacked a site that has your username and password in plain text. Now they are getting ready to try that username/password somewhere else. Beat them to the punch.
2) Use a safe browser. That means anything that's not Internet Explorer. I prefer chrome.
3) Use 2 step verification for your email account. If your email doesn't provide 2 step authentication consider switching.
4) Get a free credit report and review it. You are entitled to one free report a year. BE VERY CAREFUL! There are man scam sites that offer free credit reports. Go through the site I linked to, which is maintained by the US Government.
5) Upgrade your home wifi to WPA2
6) Phone security:
- Lock your phone with a password
- install Lookout on it so you can find it if it's gone,
- make sure you have a remote wipe capability
7) (Windows only) Install a good anti-virus/malware.
8) Review your last two sets of credit card bills and actually look at them and validate each transaction. It's common for hackers take out a small amount once to verify that they actually have a valid card, and then sell the verified number to an actual thief.
9) (expert level)Move to a secure chat client like BBM or Wickr. Stop texting and using Facebook messenger, Google hangouts, AIM etc.
10 (expert level) use a PGP (pretty Good Protection) client like Mailvelope to start encrypting your email
