根据美国总会计局(GAO)1996年年中公布的“信息安全”报告,不明人员和未经允许的个人攻击和窃取美国防部信息系统中的高度敏感信息呈增长趋势。该报告坚信实际的攻击次数是不能确定的,“因为事实上仅有很小的部分被检测出来列入报告中。”尽管如此,国防信息系统局(DISA)数据仍表明,1995年国防部经历的攻击可能多达25万次。更使人忧虑的是DISA的信息还显示攻击的成功率达到65％,而且攻击的数目逐年成倍增加。该报告认为攻击增加的原因是:使用Internet网的用户在增加,以及“黑客”(hacker)和他们所用的手段采用了更复杂的技术。
According to the “Information Security” report released by the General Accounting Office (GAO) in mid-1996, unidentified individuals and unauthorized individuals attacked and stolen the highly sensitive information in the U.S. Department of Defense’s information system. The report strongly believes that the actual number of attacks can not be determined, “because in fact only a small part has been detected in the report.” Nevertheless, DISA data still show that in 1995 the Department of Defense experience The attack may be up to 250,000 times. Even more worrying is DISA’s message that the success rate of attacks has also been 65%, and the number of attacks has doubled every year. The report said the increase in attacks was due to an increase in the number of users using the Internet and more sophisticated techniques used by “hackers” and the tools they used.
