You can disrespect your IP by losing chain of custody or by the “friend-d-a”.

Trade secrets can be lost if you have one – just one – leak to someone who does not have an NDA with you.

These types of information can be protected just by having decent procedures in place.  Keep the sensitive information in a special place, and limit access to it.

Friend-D-As are an unwritten NDA that comes from someone being too embarrassed to ask someone else to sign a real NDA.  The problem with the Friend-D-A is that it has a domino effect on all your other NDAs – sometimes with disastrous consequences.
