The cost of cyber security isn't just the purchase price

I know we often hear it said in the general security community that security is seen as a cost to the business and that’s why it can be hard to get funding.

Brian Krebbs has blogged on research examining what happens at US hospitals after a data breach or ransomware attack.
Hospitals that have been hit by a data breach or ransomware attack can expect to see an increase in the death rate among heart patients in the following months or years because of cybersecurity remediation efforts, a new study posits.

As PBS noted in its coverage of the Vanderbilt study, after data breaches as many as 36 additional deaths per 10,000 heart attacks occurred annually at the hundreds of hospitals examined.
The researchers found that for care centers that experienced a breach, it took an additional 2.7 minutes for suspected heart attack patients to receive an electrocardiogram. 
“Breach remediation efforts were associated with deterioration in timeliness of care and patient outcomes,” the authors found. “Remediation activity may introduce changes that delay, complicate or disrupt health IT and patient care processes.”

The cost of a control isn’t just in the purchase price, but also potentially in loss of productivity. In many cases an organisation accepts that cost because of the benefits the control brings. But we do need to be cognisant that their may be hidden costs to an organisation when implementing a new control. Is there really benefit in disrupting our users for some marginal security gain?

Saint-Cyr class of 1914

In his lecture The Fall of France, Mark Gerges cites the Saint-Cyr and a plaque with a year and the list of graduates who died defending France. The exception is the class of 1914, which reads the "Class of  1914". This is because 100% of the graduates of that class died defending France.

Red Army concentration of force

In a lecture to The Dole Institute of Politics, Dr. Jonathon House explains How the Red Army Defeated Germany: The Three Alibis.

In the lecture he talks about Red Army doctrine that used deception and concentration of force to achieve localised overwhelming force of numbers.

In Operation Bagration
185 Red Army divisions comprising 2.3 million soldiers and 4,000 tanks and assault guns smashed into the German positions on a front of 200 km. The 800,000-strong Army Group Centre was crushed.


House explains that on a five mile wide front, the Red Army concentrated five divisions and a separate tank brigade against one German division. There were four other places along the front with similar force ratios.

This came after the Red Army had fooled the Germans into believing an attack would come further south, causing the Germans to  move forces south.

What did they say? Forensic Transcription

Forensic Transcription Australia seeks to "raise public awareness of a legal anomaly that compromises the fairness of trials in our criminal courts on a weekly basis".

The site has an interesting video showing how priming, via a transcript, can influence a person's perception of an audio recording.

The Indian Ocean Dipole and Eastern Australian Droughts

Peter Hannam in The culprit behind east Australia's big dry explains that the Indian Ocean Dipole has a a huge effect on rainfall levels in Australia's eastern states.

In its so-called positive phase, tropical waters off Australia's north-west are relatively cool - compared with those near Africa - strengthening easterly winds and reducing the potential convection that typically supplies much of south-eastern Australia's critical winter and spring rains. A negative IOD has the opposite effect.

And of course, climate change is making it worse:
Dr Cai says that while the Indian Ocean is warming - along with others around the world - “the west is warming faster”. Under such conditions, "it’s easier to have an extreme positive IOD event", he said.
Such a future would be bad news for farmers, and raise doubts about the effectiveness of policies proclaimed to be "drought-proofing".
“We change the average climate by having these events more frequently or more strongly," Abram says. "It has an effect of changing our average rainfall.”
...
"We are perturbing the atmosphere in a profound way with greenhouse gases," England says. "How this changes our modes of variability is uncertain.”
