Computerworld has an article titled New mashup tools look to penetrate IT. At first I couldn’t stop thinking about the word “penetration” in a traditional security context. Then I couldn’t stop thinking about the danger of developers pulling data feeds from all over yonder to create a “time-saver” interface.

JackBe allows users to let Excel directly consume mashups. A plug-in is connected to the spreadsheet so that whenever data is changed, the Presto server updates the data.

Heh. And you thought you had an Excel security problem today…

Problems have already arisen with the advertising model that is used for dynamic webpages and click-through. Unfortunately I missed the Web 2.0 conference but I wonder what portion was dedicated to the “penetration” aspects and necessary controls to prevent loss of integrity or confidentiality.
