Intrusion detection systems and multisensor data fusion
Intrusion detection systems and multisensor data fusion

Google Scholar now shows my 2000 paper Intrusion Detection Systems and Multisensor Data Fusion with 848 Google Scholar citations.    I am both honored and amazed to see how much credit I have been given and all the follow-on research that credits me as the first person to apply the concepts of multi-sensor data fusion to cyberspace situational awareness and internet security in general.  These citations often motivate me to get back into the field and help push the “cyberspace situational awareness” ball a bit further up the hill.

Recently I learned that over the years “the scholars” have credited me with coining the phrase “cyberspace situational awareness” and so many other related ideas that I feel like I have let the community down by “dropping out” over the past 10 years and just enjoying my life.  It’s been great living in Thailand and scuba diving and working on other projects, but I am starting to feel like I somehow “retired” too early and left too much unfinished work.

I do admit, yes I was a bit let down when we applied these concepts to complex event processing, only to find the state-of-the-art of CEP did not support even the most basic “cyberspace situational awareness” requirements.  The closer we got to that difficult goal, the more the hype and “make a quick buck” marketeers took us off the target.  But, on a personal note, I assume it was my own weakness that I let the hype and bull-feathers bring me down and I abandoned ship, so to speak.

Not sure if I feel “regret” for ending my active involvement in the “event processing community” as I still feel that “that community” did not understand the core problem that CEP was really trying to solve.   Another person’s lack of understanding is not a good reason for me or anyone to “abandon ship” and go play golf and scuba dive – or is it?.  I am now starting to think I took the easy way out when things got tough and the winds blew back in my face very hard.

Yes, my health improved when I dropped out of corporate life.   I become more active and my weight dropped from 78kg to 67kg.   The doctors said I had revitalized my health to the body (and blood chemistry) of someone half my age.   My stress level dropped so much I had to go “look for stress” to keep the senses as sharp as a tack; doing things like planning tech dives to 120 meters in the Red Sea or other pursuits, like riding motorcycles too fast on busy streets.  My close friend here complained I had to “seek out stress” because I was not working on stressful projects anymore.

I guess that was all good, and I have no regrets – obviously I’m more calm, healthy and happy; but did I give up too early?   Did my time in CEP hurt my work in IDS and multi-sensor data fusion and cyberspace situational awareness.   I am beginning to think so.   The CEP market has all but collapsed but the state-of-the-art of cyberspace situational awareness continues to march forward thanks to all the thousands of researchers who warmly embraced and followed my vision and applied it in many ways which I am very proud of today.

What will I do next?   Ride bigger motorcycles?    Raise a family?    Revitalize my studies and research into cyberspace situational awareness?

Right now I’m just having a glass of wine and enjoying Ritz crackers and cream cheese and thinking if I might want to have  future in cyberspace situational awareness research again….. or should I just “let it go” and let the next generation carry the torch without my influence?

Update (September 2016). I made the decision to honor those who have so kindly honored me and get back to work on cyberspace situational awareness. After surveying many hundreds of downstream papers to my 2000 ACM paper, I have started work on cyberspace situation graphs.
