セキュリティをめぐるリアル社会とネット社会のアクティブな関係について

摘要

消費者の多くは，ネット社会において多大な危険に晒されているにもかかわらず，情報セキュリティの意識が低い.これは，消費者がセキュリティの問題について認知する際にバイアスがかることが原因だと考えられる.専門家の役割は，このような消費者の認知バイアスを取り除き，正しい判断を導くための情報提供を行うことである.この手がかりを得るため，家屋の物理的セキュリティの分野と比較した.物理的セキュリティは，生命や財産へ直接影響するため，消費者の意識が高い.一方情報セキュリティは，脆弱性情報や対策が広く提供されているにもかかわらず，消費者の意識は低い.消費者の意識を高めるために，ネットとリアルの結びつきを意識した情報提供を試みる価値がある.%Though most consumers are exposed to heavy risks in the Internet, they are not ready for taking enough security measures. This is considered to be caused by some cognitive bias related to their risk judgments. One of the important roles of the experts is to remove such a cognitive bias and to help them make a proper judgment. In this paper I compared the two security consciousness ordinary people have ; security consciousness of the Internet, and that of their physical properties. They are fully conscious of the physical security because this has a direct influence on their lives and properties. On the other hand, as to the information security, they hardly recognize dangers as their own though reports about weakness in the computer security are often delivered and available to every consumer. In order to raise consumers' consciousness of the information security, it seems worthwhile for the experts to give such information that helps consumers aware fully of the strong ties between their virtual and real lives.
