In fact the business aviation world has security procedures and standards.

But if you really believe that the only safe way to fly is with TSA's security theater in place, you may wish to become familiar with information such as TSA's own analysis admitting that terrorists are not planning attacks against civil aviation and there have been no attempted hijackings since 9/11. Or the fact that TSA has never foiled a terrorist attack attempt at a security checkpoint (or anywhere else).

The likelihood of a terrorist group targeting a corporate jet has not been shown to be an emminent or likely threat. And even if it were, it would be much simpler (and certainly within a well organized group's financial means) for a terrorist group to merely rent the entire aircraft in full and preclude any chance of interference from another random passenger.
