ROTFL - ;D - I knew someone was gonna say that. But you forgot to
mention religion. That also adds a 'blind faith' element which often
affects the intelligence layer.
The thought I poorly expressed, is that we're mentally boxed in by this
stupid 7-layer limit. Layer 7 is a catch-all for everything between the
'presentation' and 'user' layers. But the user still has to use the app
based on real layers of knowledge, intellect, time, politics, money and
other things. First there were (software) routers which had a list of
static or learned routes, then gateways with the previous plus a
user/password list, then application proxies with the previous plus a
list of rules. Next there is a layer of knowledge or management
required to run or 'train' that application which is missing. I'm
thinking something along the lines of a virus scanner/IDS/e-mail
surveillance app, which overseers other application proxies and data
based on higher-level rules. This could use 'fuzzy searches' of a rule
'knowledge base' to look for and identify characteristics/sources of
SPAM messages, viruses, sensitive files leaving the network, etc. In a
firewall this would equate to an advanced rule management system (hmmm,
user training is merely memorizing a set of rules). The next statement
may be then correct:
The next step in firewalls is an advanced rule system.
Maybe I should say 'knowledge app' instead of 'AI'. I meant
'Intelligence' as in 'Military Intelligence', not real intellect.
'Conciousness' can be higher yet, I've tracked errors to malfunctions at
that layer and the 'Intellect' layer. - :)
