Physical Protection • Laptops: • Multi-Purpose Hard-Shell Backpack • Tracking software • STOP Security plate • Desktops: • Lock your computer, i.e. ctrl+alt+del -> lock • Lock the door • Password protect everything • Password protected screensaver
Passwords • Things not to do: • Don’t choose a simple password like your pets name 123 • Don’t include your name or anyone in your families name • Don’t include your birthday • Don’t use common words • Don’t keep the same password for a long period of time • Don’t use the same password for every single thing that requires one.
Passwords • Over 7 characters • Upper/Lowercase + Digits e.g. AhJtKthr207 • Anny helped John take Kate to her recital • Add a date or number on the end e.g. 20th of the 7th • Make up words e.g. BloopShmear2000 or JuckNanYuck160 • Different language
Passwords • The SUPR tests • The Strong test: Is the password as strong (meaning length and content) as the rules allow? • The Unique test: Is the password unique and unrelated to any of your other passwords? • The Practical test: Can you remember it without having to write it down? • The Recent test: Have you changed it recently? • Keep them guessing!
