As anyone living in the UK will know, data security is a big issue, with a recent breach of very personal data for a large percentage of the population. I think the problem is that data security costs money to implement and needs very skilled staff, moreover is often hard to implement it properly.
Its because the issues involved are so complex, and on top of that most people find it hard to understand the criminal mind, that it takes a problem for people to sit up and listen.
Security is costly to implement properly and can put serious restrictions on what people can do with the system, and needs proper analysis before any changes are made to a system. At least in this latest incident we got to find out about it because it was linked to a government department. I guess in some other circumstances it would have gone un-noticed.
