System security is a very broad and complex subject. But basically, a good electronic health information system should:
• Take into account system security needs in the initial design of the system.
• Have appropriate backup - to protect against loss of image inventory in the event of accidents. For example, Tan Tock Seng Hospital have a 24 terabytes off-side storage system.
• Have adequate backup power supply
• Have Inbulit security mechanisms such as
• Encrytion
• Firewall
• Intrusion detection system
• Anti-virus capability and so on
