Before you begin any ethical hacking, you absolutely, positively need everything
in writing and signed-off on.



Hi, I wonder what the sentence mean..
In particular, the "need everything in writing and signed-off on" part..

Getting someone to sign off on something means getting them to review and approve it. For example, an employee might get his/her boss to sign off on their work on a particular project before they go forward with it. An attorney has to sign off on the title search on a real estate transaction, etc. etc.
