I spoke on the executive track at the NSA/DISA Information Assurance Symposium in Nashville yesterday. My talk was on how consumerization and mobility are changing how IT security has to be delivered. I decided to base the talk on this analogy:
Back in the early cave people days, there was no fire. Then lightning caused fire, or a cave person dropped a rock that caused a spark and started a fire or whatever. Dangerous stuff, but turned out fire was pretty useful – but unpredictable. A few smarties figured out how to start fires from burning embers and then figured out how to carry around those burning embers to start fires whenever and wherever they wanted to -they were the “keepers of the flame.” Anyone who wanted fire had to go to them – they were basically the Chief Fire Officers (CFOs).
Flash foward a few thousand years and in 1827 the safety match was invented – and anyone could go around the CFO and create their own flames. This lead to many burned fingers, cows kicking over lanterns burning Chicago down, arsonists – lotsa risks – but also many innovative uses of fire, like candles in the shape of bunnies and really tasty Smores concoctions at campfires. Leap ahead to about 1960 and we had evolved to have the National Bureau of Standards define fire safety standards, insurance company sponsored fire stations had evolved into community volunteer/professional firefighters and we learned that actually letting forest fires caused by natural firews burn where possible was actually better than immediately putting them out.
Jump to 1982 and the PC is the safety match that bypassed the ADP keepers of the mainframe IT flame, and today smart phones and Internet/cloud services are the next generation safety matches that are bypassing the CIO/IT group keepers of the enterprise IT flame – and it is not going back, there will be more IT equivalent of Bic lighters to come. Security strategies that are based on hoping the mainframe will come back will be bypassed like those little towns that were built 20 miles apart (because that is how far a horse could go in a day) got bypassed when the Interstates were built.
