据安全部称:在2003年6月6日,全球黑客举行了一次较大规模的入侵互联网的比赛。总部设在爱沙尼亚,对黑客袭击进行了跟踪的网站Zone-H.org的创始人Roberto Preatoni表示,比赛只开始几分钟便结束了,他们共录得了300份袭击报告。而此次“活动”所折射出的另一个问题则是病毒的发展和传播速度是迅速的,而病毒在很大程度上是靠便捷的电子邮件进行传播的。由此,如何保护电子邮件的安全成为了当务之急。 According to the Department of Security, on June 6, 2003, hackers around the world held a large-scale invasion of the Internet. Headquartered in Estonia, Roberto Preatoni, founder of Zone-H.org, which tracks hacking attacks, said the race ended in just a few minutes, with a total of 300 raid reports. Yet another issue reflected in this “event” is the rapid development and spread of the virus, which is spread to a great extent by convenient e-mail. As a result, how to protect the safety of e-mail has become a top priority.
