With the expansion of the Internet, system administrators cannot keep up with the new viruses and security vulnerability information. As Code Red and the Nimda Worm spread globally in 2001, the understanding of how to prevent such viruses was not sufficiently disseminated from system administrators to users. Although companies like Microsoft and CERT published security information, many users did not take action. Myriad security advisories confused many users because the system environments they covered differed from those of the users. Here, the issue of context sharing comes into play, as many users cannot identify the context of the messages they read, or identify the portions of the messages that are relevant for their own context.
