There appears to be a serious and general misunderstanding of these terms somewhere. If people are allowed to carry information on laptops or portable media it is likely that what they are actually carrying is likely to be an archive of everything they’ve ever copied to their laptops. By what authority do they take the data? Have they agreed and signed a document defining their authorities and responsibilities?
How many processes are in place to ensure that ‘data taken yesterday' will have been a) returned (unchanged or edited)?; b) purged after the individual's return to the office? I bet there are few security processes in place to track the use of sensitive data. Dissemination of data to third parties should be also be specified/recorded and appropriate safeguards for tracking such data assured.
I'm deliberately ignoring the question of protection and encryption because what matters is that data has been 'lost' and, and therefore by definition, compromised. Encryption might be equated to the use of ABS systems on cars – useful if you get in to a difficult situation but hopefully should only be applied in dire circumstances. It has been shown that advanced vehicle safety systems tend to reduce the perceived ‘responsibility’ of drivers.
I will mention the question of 'sensitive' data. The classification of data should be approved in all cases and means of tracking the use of data should be in place according to the 'sensitivity' of the data. How often is data sensitivity determined, and by whom? (Who watches the Watchers?)
Back to Authority and Responsibility; if an individual has the Authority to remove data from the workplace that person should be endowed with, and respect, obligations to demonstrate their Responsibility that data. Acceptance of and compliance with such obligations should be reinforced through the medium of legally-enforceable documents or other sanction mechanisms
The general problem appears to be that certain organisations and authorities employ uncaring, overloaded, thoughtless, untrained or indifferent individuals who don’t recognise or respect or have forgotten their responsibilities. (E.G. Trust me – ‘I have an important job and know what I’m doing’). Furthermore I suspect that follow-up training and renewal of approval is not carried out in an effective manner. When organisations are short of cash or resources training and security are the first victims.
Responsibility should not have a ‘glass ceiling’. Ultimately it is the senior person, the security officer, the CEO, MP, ministry official etc. who has personal responsibility – beyond that, the organisation paying for the service (the customer at the top of the pile) has a responsibility to ensure, through repeated audits, checks and balances that their suppliers or contactors are ‘doing their job’ properly and are meeting all obligations. This, of course, requires the ‘customer’ to provide unambiguous, atomic, requirements to be met in the first place. There is no sin in admitting that such requirements need to be revised from time to time and costs may accrue as a result but hey, these costs have to be borne somewhere – and certainly not by innocent victims of such failures.
The recent changes in law regarding ‘corporate manslaughter’ might provide a precedent.
End of diatribe.
