Mary Jo White, head of the Securities and Exchange Commission, told members of the financial industry Tuesday that technological failures in the marketplace are unacceptable. "The key is a zero-tolerance objective," White said. "We obviously know that in any system you are going to have issues, and you also need to have a very robust way to respond, a very quick way to respond, a good way to communicate when you actually do have an incident." White also set high standards for the SEC when it comes to enforcing the financial industry's rules and regulations, calling for the agency to be "bold, unrelenting, but fair."
