desk and file cabinets before you leave for the night. Don’t talk
about the specifics of your work outside your team. (You can tell
your significant other only if he or she doesn’t pose a security risk.)
Don’t take out sensitive material in public—sensitive means anything
that a competitor or journalist might find interesting. Be
mindful of what you say over the phone, and be extra careful when
sending faxes, e-mail, and voice messages: They can very easily end
up in the wrong hands.
