Next generation SCADA security: best practices and client puzzles

摘要: Supervisory control and data acquisition (SCADA) systems are found throughout the public utility industry. As part of our national critical infrastructure, SCADA used to monitor, manage spatially separated sites. mirroring rapid changes occurring in larger information technology (IT) networking industry by becoming more flexible at same time interconnected. These primitive being upgraded using commercial-off-the-shelf (COTS) hardware software, migrated standard formats network protocols, particularly transport protocol (TCP) for end-to-end control. Throughout this transition, system networks must be well defended maintain level service required their customers.
