Hi.,

The sustainability is an emerging megatrend, and thus its course is to some extent predictable. ... and 1990s, and the trend accelerated as IT made its way into the daily lives of workers ... leadership, and other intangibles to secure durable competitive advantage.

I suppose that the question is how can security be solid and fulfill its protective mission over time?

There are two elements of answer I can provide:

-a structural design which is robust to changing threats

-an adaptive monitoring and learning, detecting threats and adversary behaviours.

In other terms, you can separate the technical system and the process for operating it into:

-baseline

-delta, incremental.

You can enrich the approach by detecting non linear disruptions (like the US driven subprime mortage crisis which has been catastrophic for financial institutions), and preparing a brandnew system, complete change and replacement, in case this happens.

To do this instead of making an order one Taylor development, that is assuming that f(x+dx) = f(x) + f'(x)dx approximately, you go to the second order and look at second order derivative f''(x), which describes convexity/concavity.

I have used this in one of my published results many years ago. It still is valid as an approach...

It is a new practice that combine national security with human security and collective security. It is a new perspective in which the focus is not solely on traditional threats, but also on an effective international development and work to protect innocent civilians.
