问题 单项选择题

以下不属于物理访问控制要点的是()

A、硬件设施在合理范围内是否能防止强制入侵 

B、计算机设备的钥匙是否有良好的控制 

C、计算机设备电源供应是否能适当控制在合理的规格范围内 

D、计算机设备在搬动时是否需要设备授权同行证明

答案

参考答案:C

解析:

物理访问控制是设计用以保护组织防止未授权的访问,并限制只有经过管理阶层授权的人员才能进入。物理访问控制要点主要包括:

1)硬件设施在合理范围内是否能防止强制入侵。

2)计算机设备的钥匙是否有良好的控制以降低未授权者进入的危险。

3)智能终端是否上锁或有安全保护,以防止电路板、芯片或计算机被搬移。

4)计算机设备在搬动时是否需要设备授权通行的证明。

选项C“计算机设备电源供应是否能适当控制在合理的规格范围内”是错误的,它属于应用环境安全控制要点的内容。

When Dr. John W.Gofman, professor of medical physics at the University of California and a leading nuclear critic, speaks of "ecocide" in his adversary view of nuclear technology, he means the following: A large nuclear plant like that in Kalkar, the Netherlands, would produce about 200 pounds of plutonium each year. One pound, released into the atmosphere, could cause 9 billion cases of lung cancer. This waste product must be stored for 500,000 years before it is of no further danger to man. In the anticipated reactor economy, it is estimated that there will be 10,000 tons of this material in Western Europe, of which one table-spoonful of plutonium-239 represents the official maximum permissible body burden for 200,000 people. Rather than being biodegradable, plutonium destroys biological properties.

In 1972 the U.S. Occupational Safety and Health Administration ruled that the asbestos level in the work place should be lowered to 2 fibers per cubic centimeter of air, but the effective date of the ruling has been delayed until now. The International Federation of Chemical and General Workers’ Unions report that the 2-fiber standard was based primarily on one study of 290 men at a British asbestos factory. But when the workers at the British factory had been reexamined by another physician, 40--70 percent had X-ray evidence of lung abnormalities. According to present medical information at the factory in question, out of a total of 29 deaths thus far, seven were caused by lung cancer. An average European or American worker comes into contact with six million fibers a day. "We are now, in fact, finding cancer deaths within the family of the asbestos worker," states Dr. Irving Selikoff, of the Mount Sinai Medical School in New York.

It is now also clear that vinyl chloride, a gas from which the most widely used plastics are made, causes a fatal cancer of the blood-vessel cells of the liver. However, the history of the research on vinyl chloride is, in some ways, more disturbing than the "Watergate cover-up." "There has been evidence of potentially serious disease among polyvinyl chloride workers for 25 years that has been incompletely appreciated and inadequately approached by medical scientists and by regulatory authorities," summed up Dr. Selikoff in the New Scientist. At least 17 workers have been killed by vinyl chloride because research over the past 25 years was not followed up. And for over 10 years, workers have been exposed to concentrations of vinyl chloride 10 times the "safe limit" imposed by Dow Chemical Company. (422 words)
