The landing gear light indicated a problem. The captain, first officer and flight engineer of Eastern Air Lines Flight 401 tried to figure out what was wrong. They removed the light assembly and the flight engineer left his position to go to the avionics bay and investigate. They were so preoccupied with a burnt out…Details
When it comes to security awareness, there’s no such thing as a blank canvas. Your audience will already have pre-conceived notions about your topic. The language, tone and media you use will invoke associations in people’s mind, both helpful and unhelpful. These associations will influence how people view the root causes, likelihood and potential outcomes.…Details
There’s no denying that some people are impervious to our attempts at security awareness and refuse to listen to warnings or instructions. There is a temptation when things go wrong to label such people as ‘bad apples’. I think that this saying is overused. Originally, the expression ‘bad apple’ referred to a rotten apple in a barrel that would spoil the good apples. Usage of the phrase has changed and its now often used to explain failures of scale. The perception is that when there are many apples you have to expect some of them to be bad.
I often hear the phrase used when a governance failure is attributed to human mistakes. Frequently however, I think the phrase bad apple is a convenient cover for poor management where processes and procedures were badly designed or supervised. The bad apple narrative can suit prejudices of humans being a weak link and any narrative is more comforting than no narrative at all. However, bad apple narratives rarely withstand serious scrutiny.Details
Any endeavour is made doubly difficult when pursued with a lack of metrics and without a clear understanding of cause and effect. When stumbling in the dark, facts are the flashlight of comprehension, illuminating the way forward when the path is unclear. Information security is often required to function in the dark with little in the way of facts to guide us. We hear noises and bump into things but can never be certain if we’re going in the right direction.
When security fails, how do we know? While failures of integrity and availability are obvious, failures of confidentiality can be silent and insidious. Some actors such as LulzSec boast about their exploits and derive their benefits from the resulting publicity. Other actors quietly go about their ‘business’ and organisations may not realise they’ve been breached. Often, even when we do discover failures of confidentiality the organisational interest is to bury it. As a result, our profession is rich in rumours but poor in facts which make it difficult when trying to understand the effectiveness of security controls.Details
