    CHAPTER 8 Security Actions With more sophisticated and extensive use of servers, concern over the security of server systems has become increasingly important. In an online application, for example, a disruption of the central system would degrade or shut down the functionality of the terminals, which could have social or economic consequences depending on the nature of the application.

  • Page 114: Objects Of Security

    CHAPTER 8 Security Actions 2 If a disaster occurs, services are closed down, but can be resumed immediately when the disaster is over. Services are closed down temporarily to protect against errors or malfunctions that might arise from continuing to run the server system for the duration of the disaster, or from problems in running associated facilities.
