20 Years of Information Security: Revolution or Evolution?

The Vision from 1989
Computer systems as we know them were in their infancy in the waning moments of the 1980’s and the early years of the 1990’s. Systems were still largely segregated by manufacturer. IBM shops had no DEC equipment anywhere, and vice versa. HP systems were found in manufacturing plants, and the world of CAD/CAE was dominated by stand alone graphical units that were the engineering versions of the memory typewriter.
As a CIO, my primary responsibilities were to integrate applications, reign in the size of databases and figure out how to integrate the Personal Computer into the work environment productively. Security was being promulgated in the form of model architectures and the “rainbow series”
Bang!
Within the next ten years, we were enveloped in the “dot-com” boom. Technology permeated every aspect of our lives. Billion dollar companies sprinkled the plethora of Silicon Valleys that were created across the country and the world in respectful imitation of their California heritage. What were we envisioning from the Information Security domain?
In many instances, what we were looking to do was revolutionary. We saw that virus code and other malware instances were gaining in popularity and Scott McNealy from Sun Microsystems warned that there is no longer any digital privacy .
So what have we actually done? Sometimes we have seen a revolution, sometimes we have seen a slower crawl forward, something we’ve seen nothing in 20 years. Let’s take a look at what has transpired over the past score of budget cycles:
Human Resources and Staffing
In 1989, security professionals were either writing crypto code for the military or were hanging backup tapes in a data center.
Today we are blessed with more than a dozen ways of measuring the security competence of our staff. We have training programs and conferences up the wazoo and enough credentials to exhaust a box of alphabet soup.
Verdict: Revolution
Network Architecture
In 1989, open systems were beginning to babble to each other. Communications was over leased lines or internal networks. Nobody ever used dial-up public communications for sensitive data (if you knew what data was actually sensitive).
Secure network architecture is now available on the shelf at the office supply store. Data in flight is routinely encrypted over public networks, and a major sub industry to monitor, trace, prevent, and identify rogue communication attempts have flourished.
Verdict: Revolution
Systems Development
The good old five (or six depending on your school of thought) phase approach to designing systems was de rigeur in 1989. Application teams went through stages of Scope, Design, Programming, Unit testing (& System Testing) and Implementation. Once all this as done, someone may have asked: “What about backup and recovery?”
The method is the same. Only some of the questions have changed. The question of compliance with laws and industry standards is now part of the design stage of major applications. Along with the questions come the parameters of secure application architecture. Several models exist, but are employed primarily by those who are up on the latest trends.
Verdict: Evolution
Monitoring and Forensics
In 1989, logs were generated and maybe printed. Tracing events were rare, but also largely unnecessary. Nearly everything could be reproduced or rerun if something bad happened, and only occasionally could people actually commit crimes with computers. (I remember in the mid 80’s in several states, computer crimes existed only when someone hit somebody else with a keyboard.)
Today, compliance laws and industry regulations have tightened the need for monitoring and active event investigations. Not only do you need to print the logs, you also need someone to review them. A log scanning software industry is being born. Can you hear it?
Verdict: Revolution
Business Awareness
Finally, let’s take a look at what the business sees as Information Security. I had a discussion with my company CEO regarding a security policy. We designed and built coal-fired steam-driven power plants. His answer was “Everyone knows that water boils a zero degrees centigrade at sea level. We don’t have any trade secrets.” Obviously national defense and some very creative industries were concerned, but not the average commercial organization.
Business Continuity and Data Privacy concerns are starting to find their way into board room discussions. Hurricanes, floods, terrorism are dominating the discussion of companies concerned about maintaining industry presence. Regulated industries are leading the way at identifying, segregating and protecting data that must be kept private. Laws are replicating like rabbits in a dark room. We are only seeing the beginning.
Verdict: Slow Starting Revolution
Summary
In these and other areas, we have made substantial progress in information security over the past 20 years. There is more to come. Here’s my prediction: over the next 20 years, security will be embedded in all information management technology. Data segregation will be the usual architecture, trace logs and factual responses to “how did that happen” will be commonplace. Hackers and malware will exist but will be just an annoyance.
Hmmm. Didn’t I say that in 1989?
