  1. Teenagers
  2. Terrorists
  3. Hacker clubs
  4. Organized crime[/ordered_list]

2. Which three basic properties are the building blocks of cyber security?

[ordered_list style=”lower-alpha”]
  1. Identification, Integrity, and Authorization (I I C)
  2. Confidentiality, Integrity and Availability (C I A)
  3. Authorization, Reliability, and Integrity (A R I)
  4. None of the above[/ordered_list]

3. What is the biggest security problem if business networks connect directly to
manufacturing control systems?

[ordered_list style=”lower-alpha”]
  1. Too many business users requesting data will slow control system operation to
    a crawl, endangering the security of processes.
  2. Production workers will change data in business systems given the opportunity.
  3. Outsiders and malware can penetrate critical industrial control systems and
    upset critical processes.[/ordered_list]

4. If a denial of service attack shuts down an industrial network, which basic security
property is affected?

[ordered_list style=”lower-alpha”]
  1. Usability

ISA and O3neida publish Agent-Based Technology Manufacturing Control Systems

ISA’s ongoing publishing partnership with O3neida has produced a new technical publication, Agent-Based Technology Manufacturing Control Systems, Luca Ferrarini and Arndt L├╝der, editors.

This practical reference focuses on a new design technology and process specifically conceived for reconfigurable manufacturing system control. It represents the first integrated application in real industrial environments of agent-based technology, ontology-based description and IEC-61499-based automation solutions for production systems. Ideal for practitioners, this guide describes the benefits of new concepts and technologies related to reconfigurable manufacturing systems from a pragmatic, industrial perspective.

Most of the work is devoted to agent-based plant-level control, which is conceived as a generic executor of manufacturing recipes, scheduling rules and production orders.

In partnership with O3neida, this volume is the latest in a series of books on automation technologies that was introduced in 2008 when the first book, IEC 61499 Function Blocks for Embedded and Distributed Control Systems Design, by Dr. Valeriy Vyatkin, was published.
