I never had to sign one when a company employee and, surprisingly, I’ve never had a client ask me to sign one now that I am consulting. I do make it clear in bids, though, that I make a data confidentiality pledge. If I hired am employee or subcontracted any work, I would include data confidentiality in the work standards section of our agreement.

I work for a law enforcement organization. Everyone here has signed the form that says I have read the employee handbook and will abide by its instructions. We can be disciplined, fired, or prosecuted for violating confidentiality.

We have policies and procedures in place we are required to read, but we were not required to sign anything. We also have auditing in place should there be any doubt that access is being used for nefarious purposes other than legitimate business. Quest has a good auditing software among their many products.

In thinking more about your question, I remembered one I had seen that was pretty good from Sans.org. https://www.sans.org/security-resources/ethics.php
