Principles of Technology EthicsPrinciples of Technology Ethics

• Proportionality• The good achieved by the technology must

outweigh the harm or risk; there must be no alternative that achieves the same or comparable benefits with less harm or risk

• Informed Consent• Those affected by the technology should

understand and accept the risks

13-15

Principles of Technology EthicsPrinciples of Technology Ethics

• Justice• The benefits and burdens of the technology

should be distributed fairly. • Those who benefit should bear their fair share

of the risks, and those who do not benefit should not suffer a significant increase in risk

• Minimized Risk • Even if judged acceptable by the other three

guidelines, the technology must be implemented so as to avoid all unnecessary risk

components• Fail-save capability: the system continues

to operate at the same level• Fail-soft capability: the system continues

to operate at a reduced but acceptable level

13-73


• A disaster recovery plan contains formalized procedures to follow in the event of a disaster• Which employees will participate• What their duties will be• What hardware, software, and facilities

will be used• Priority of applications that will be processed• Use of alternative facilities• Offsite storage of databases

known as “Patch Tuesday”• Security software companies go to work

immediately to update their products• Update must be thoroughly tested before

being deployed

13-81
