As an example. Having the internet searchable is useful, us convienent. But it reduces security because of its convienence. This breach would not have happened without that convienence. UX could have made it easier to remember to robots file. So could process, or review or other security practices. But no UX is gonna solve fact that internet is insecure due to its convienence. The internet can never be secure. At best you can get lower levels of insecurity.
