Wreski says one of the best ways to leverage least privilege is to find vendors that have used this development in the past. He comments, 'For this, it helps significantly to have both the OS and the application come from secure, unified development. Unified development from security vendors is one of the best ways to ensure that both applications and the platform are engineered with least privilege…
