Correspondence Patterns

I like the conclusions in this study:

“Darwin and Einstein correspondence patterns: These scientists prioritized their replies to letters in the same way that people rate their e-mails today.”

Not only does it vindicate my habit of attending to some communication instantly, while letting other things wait for eons, but it also raises interesting implications for confidentiality and data retention.

Preacher killed by baptism

I know this is more about safety than security, but I just found the story somewhat shocking:

“Rev Kyle Lake, 33, was standing in a small pool used for baptisms at the University Baptist Church when he was electrocuted on Sunday morning. Rev Lake reached out to adjust a nearby microphone, which produced an electric shock, said church pastor Ben Dudley.”

Sad but true.

SCADA systems come into focus

SecurityFocus reports today that US SCADA systems are finally getting the attention they deserve:

“Wary of the increasing number of online attacks against industrial control systems, the U.S. government has begun a major push to secure the systems used to control and monitor critical infrastructure, such as power, utility and transportation networks.”

I did some consultative/audit work with a utility company in the late 1990s and was surprised that networked systems had become so commonplace with so few controls. Fail-safes were everywhere for the critical infrastructure (most of which was heavily engineered and influenced by ideas that probably went back to the beginning of utilities themselves) so disasters seemed unlikely without some knowledge or access, but simple network devices (routers) and Microsoft software were spreading like crazy to “increase efficiency” for remote management and control systems.

To be fair, that all was before the Critical Infrastructure Project (CIP) was even started. I just checked their online files and it seems that progress is slow but steady.

Bio-Diesel and the Military

I just ran across a report by Wired, published on September 28th, called “Green Berets Prefer Biodiesel“. I am thus happy to correct myself and say my earlier post on this subject, as well as the follow-up, were a bit hasty. Wired says that the military has been steadily increasing bio-diesel use for several years now.

This is great news for several reasons. The military move towards diesel motorcycles may quickly prove the viability of a robust yet small consumer engine. In addition, the fact that the Army, Navy, US Postal Service, Department of Agriculture, and NASA are all looking at bio-diesel means a more acceptable alternative to petroleum-based fuels could be on the precipice of mass adoption in a country that has been virtually blind to the importance of alternative fuels.

“That’s important to the military’s role as a public citizen, says [fleet manager for Marine Corps vehicles in Camp Pendleton] Funk. ‘We operate our vehicles on the public highways,’ he says. ‘Biodiesel sends a signal to the American public that we’re working to keep the air clean, and to reduce our dependence on foreign oil.'”

Admittedly, while it is nice to hear fleet managers give a kinder-gentler environmental message, the realist/security practitioner in me says bio-diesel is a more secure and sustainable fuel for domestic as well as foreign troop deployments. The article even mentions that waste oil from the mess halls is now used to fuel the transport vehicles. No matter how you slice it, bio-diesel is the fuel that just keeps giving — engines run longer (better lubricity) as well as cleaner (less smoke) and can take just about any fat/oil you can scrounge up, which leads to far less vulnerability in storage and transit. It stands to reason, therefore, that special forces would go this route given the obvious reduction in vulnerabilities compared to traditional petroleum supply-chain and storage.

Just imagine if consumer-grade Diesel engines today had half as much development and innovation effort put into them as other engines (like the new Corvette Z06 powerplant). I look forward to a diesel-hybrid in the (near?) future for the ultimate in efficiency and performance without the inherent security risks of petroleum.
