Having lived through the development of the industry, we can safely categorize most security technologies as following a similar path:
1. Initial idea by a smart sumdood leads to new product: antivirus, firewall, that sort of thing. This is the I bet we could do something interesting phase.
2. The technology matures, as initial customers on the "bleeding edge" suffer for the rest of us, but the biggest problems get addressed or the technology dies. This is the I bet we could actually make this thing work phase.
3. Senescence sets in, as excessive focus on features, rather than on the overall system cause the creation of quite frankly bizarre capabilities that eventually kill the product. This is the Hey, hold mah beer phase. Srlsy.
Ever wonder why your antivirus agent suddenly consumes 100% of your CPU? Hold mah beer. Ever wonder why so many people turn off their Intrusion Detection? Hold mah beer.
The focus on the trees, rather than the forest - on new features to the exclusion of how the system works - seems endemic. The dynamic of having to compete on feature/functionality in a mature and stable market seems to drive good products off a cliff more often than we'd like to think.
The damn things become unusable, and so people turn them off.
I just turned off CAPTCHA codes for comments. We'll see how that goes - I don't like turning security off, but the "improved" CAPTCHAs seem to be well into phase 3. Google doesn't seem to realize that now they're blocking legitimate commenters who get frustrated and quit. I think I've heard this song before.
