There are no facts, only interpretations…
More woes for OPM, and pause for thought for the proponents of centralized government data stores. If you build it they will come…and steal it.
Hannibal ante portas!
A recent article in Wired discloses how hospital drug pumps can be hacked and the firmware controlling them modified at will. Although in theory the comms module and motherboard should be separated by an air gap, in practice there’s a serial link cunningly installed to allow firmware to be updated via the interwebz.
As the Romans found, once you’ve built a road that a legion can march down it’s entirely possible for Hannibal and his elephants to march right up it. Thus proving once again, if proof be needed, that there’s nothing really new under the sun. In a similar vein we probably won’t see any real reform in this area until someone is actually killed or injured.
This has been another Internet of Things moment of zen.
A tale of another two reactors
There’s been much debate over the years as whether various tolerance of risk approaches actually satisfy the legal principle of reasonable practicability. But there hasn’t to my mind been much consideration of the value of simply adopting the legalistic approach in situations when we have a high degree of uncertainty regarding the likelihood of adverse events. In such circumstances basing our decisions upon what can turn out to be very unreliable estimates of risk can have extremely unfortunate consequences. Continue Reading…
The current Workplace Health and Safety (WHS) legislation of Australia formalises the common law principle of reasonable practicability in regard to the elimination or minimisation of risks associated with industrial hazards. Having had the advantage of going through this with a couple of clients the above flowchart is my interpretation of what reasonable practicability looks like as a process, annotated with cross references to the legislation and guidance material. What’s most interesting is that the process is determinedly not about tolerance of risk but instead firmly focused on what can reasonably and practicably be done. Continue Reading…
Safety versus security
There is a certain school of thought that views safety and security as essentially synonymous, and therefore that the principles of safety engineering are directly applicable to that of security, and vice versa. You might caricature this belief as the management idea that all one needs to do to generate a security plan is to take an existing safety plan and replace ‘safety’ with ‘security’ or ‘hazard’ with ‘threat’. A caricature yes, but one that’s not that much removed from reality :)
