Disaster Recovery vs Business Continuity

Disaster Recovery is not the same thing as Business Continuity. For an example, you need look no further than the recent British Airways system failure. Lasting several days, the outage affected more than 75,000 passengers across 170 airports in 70 countries. During the outage, British Airways could not process passengers, meaning outbound flights could not take off, and planes were stuck at gates.

The problem began with a power surge that "only lasted a few minutes", but the back-up system had not worked properly.

There's a lot of finger-pointing at British Airways, but I prefer to use this as an example of how Disaster Recovery is not the same thing as Business Continuity.
A disaster is when things fail.

Disaster Recovery is the IT folks bringing servers back up and getting computer systems back online.

Business Continuity is how the business keeps operating in the face of the IT system failure.
In the case of British Airways, the IT folks were busy restoring power to the mainframe, bringing up the backup system, and synchronizing data. That's Disaster Recovery.

Meanwhile, in the airports, on-site staff used whiteboards to communicate flight status, and used runners and other communication methods to get information between gates. That's Business Continuity.

Take this opportunity to review processes and procedures in your own organization. What does your Disaster Recovery plan look like? Do you have one? Does everyone in the IT organization know how to bring systems back online in the face of failure?

At the same time, what does your Business Continuity plan look like? This needs to come from your business units, to plan how they will keep operating if the technology becomes unavailable. The Business Continuity plan cannot be to yell at the CIO until systems come back online. Every business unit needs to create and manage their own plan about how they will continue to do business in the sudden absence of technology.

Common security issues

I have been working in IT for over twenty years. I got my start as a Unix systems administrator at a small company, then moved into a "working manager" role at another small company, before moving into higher education where I eventually led the Enterprise Operations and Infrastructure teams for a Big Ten university. After that, I transitioned to a campus leadership role, as campus CIO at a coordinate campus. Now I am the chief information officer for county government.

In my time working in technology, I have watched the rise of online security. When systems are connected to the Internet, they are at risk to cyber attack. In 2017, if cyber security is not a key focus area for your organization, you are falling behind.

As if to demonstrate, the UK's National Health Service (NHS) was recently stung by ransomware, a common form of attack. This was one of several WannaCry attacks worldwide. And if  you're still running Windows XP, it's only going to get worse.

What are the security issues you should be most concerned about? While I don't claim to be a security expert, I can speak from some experience here. This is part of my list of the top security improvement opportunities for most organizations:
  1. Patching, and retiring out of date systems
  2. Intrusion detection
  3. Automated system monitoring
  4. Private IP space and bastion hosts
  5. Distributed architecture
  6. Separation of privilege
  7. Access controls review
  8. Single sign-on, with two-factor authentication
  9. Firewall and VLANs
  10. Data at rest encryption
What would you add to the list?

High academic vs Low academic

I loved this article from The Conversation, about how Academics can change the world, if they stop talking only to their peers.

Having spent seventeen years in higher ed, much of the article resonated with me. From the article:
This suggests that a lot of great thinking and many potentially world altering ideas are not getting into the public domain. Why, then, are academics not doing more to share their work with the broader public? The answer appears to be threefold: a narrow idea of what academics should or shouldn’t do; a lack of incentives from universities or governments; and a lack of training in the art of explaining complex concepts to a lay audience.
The article reminds us that many academics don't believe it's their job to communicate with the lay public. There's really no motivation to do so. If you're chasing tenure, writing in trade magazines or newspapers may not "count" towards your publication credit, anyway. And once you have tenure, writing for non-peer-reviewed venues may be considered "cheap."

I observed that attitude several times when I worked in academia. I remember our campus held an annual celebration of scholarly faculty achievements. Faculty were invited to submit samples of their work that had been published in the previous year. I also remember commiserating with friends in the faculty who failed to get recognized because they wrote in non-academic journals and magazines. They wrote for the common reader, not other academics.

The article also highlights that even when academics feel motivated to write for a broader audience, it may be difficult for them to get published. As the article points out, "Writing an article for an academic journal is a very different process to penning one for those outside the academy." When you've been trained to write "academic" speech for your whole career, it can be difficult to construct prose that is more approachable.

I have a similar view. When I was in my Master's program, I referred to three different styles of writing: "High academic," "Medium academic," and "Low academic."

High academic is typical for many peer-reviewed journals. This writing is often very dense and uses large words that demonstrate the author's command of the field.

Medium academic is more typical of undergraduate writing. It is less formal than high academic, yet more formal than what you find in the popular press.

Low academic tends to include most professional and trade publications. Low academic authors may sprinkle technical terms here and there, but generally write in a way that's approachable to their audience. They use contractions, although sparingly. Certain other conventions continue, however. Numbers are written out; "fifty" instead of "50," and "two-thirds" instead of "2/3."

In my Master's program, I learned to adjust my writing style according to my instructors' preferences. One professor might have a very formal attitude towards academic writing, so I would use High academic. Another professor might approach the subject more loosely, so I would write in Medium academic. When I translated some of my papers into articles for magazines or trade journals, I wrote in Low academic.

Academics need to adopt a similar approach. It's okay to write in High academic when you are writing for your peers, in academic journals. But the academy needs to be visible to the public, to share their findings in a way that non-academics can understand. That means adopting a Low academic style.

The article concludes with a similar message, but also adds that universities need to change their attitude about what should "count" as "publication," saying:
Doing this sort of work ought to count towards promotions and should yield rewards for both universities and individual academics. Quality academic research and innovation are crucial. It is equally important, though, to get ideas out into the world beyond academia. It could make a real difference in people’s lives.
And I agree.

My start with Linux

When I was an undergraduate physics student, I discovered this little thing called Linux. It was a great Unix operating system that I could run on my PC. And I've been a Linux fan ever since.

I wrote a full story for, about How I got started with Linux. Please read it!

Every meeting

I'm taking a break this week (I'm grading final exams for the online class I'm teaching this semester) so instead of a longer post, I wanted to share this brief video from FastCompany.

» Every meeting you've ever been to (in two minutes)

How many meetings have you been to that are like this?

Sure, the video is funny, but that's not the reason I shared it. I'm hoping the video may knock you out of complacency, and get to you recognize any of these bad behaviors in yourself (if you have any). So if you're exhibiting any of the traits from this video, if you listen to yourself in your next meeting and hear yourself saying some of these trite examples, you need to find new ways to express yourself.
