Fraud on social networks: security or education issue?

The article probably reiterates what is already known, but I found it interesting because it explains with details how the lack of security is increased by the combination of people not using their common sense and the presence of networking offered to them by Twitter, Facebook, LInkedIn which all link together rather than being compartementalised.
Maybe people do need to be educated after all on this, notably in realising the snowball effect of having details exposed and linked to different sites.

The same issue seems to exist in the financial sector, which is pretty scary given the amount of financial data at stake and what it means for fraud. The study was provided by Cabinet Deloitte; it is in French, but still more or less readable because a lot is in tables. The most interesting thing for me was the last table: human error accounts for 86% in 2008 (79% in 2007) for breaches in security. In other words, people need to start taking responsibility for maintening security and stop blaming softwares developers and the like.
