Mr. Simon O'Brien:

We need to be very clear. We were looking for specific security threats in terms of the physical security of the buildings and the issues of capability against mobile telephony. It is a lesson for us all, and we have had to put out a number of messages internally to our staff colleagues, that it can be very unhelpful and damaging to release any information to unauthorised third parties, be that through conversations or otherwise. It can also be an issue of real concern if people are careless with people's information by allowing it to exit the building, dropping it or leaving it for others to see. We have had to deal with flows of information and, to come back to where I started, in an information age - we currently have all sorts of ways of accessing information, and it is a vital resource that some may even pay money for - we have had to make that very clear, because in the very recent past it seemed to me that information that was known only to a few people inside our organisation suddenly appeared within newspapers' newsprint. We have had to remind our own staff, therefore, about their responsibilities.
