But they are critical infrastructure targets, and they're quite numerous-
both of them potentially making them attractive to disruptive folks.
Now, there are several possibilities as to why they're not often targeted
with automatic malcode:
1. Lack of platform information (obscurity.)
2. Cost of platform (availability.)
3. Specificity of device.
4. Limited scope of IOS images (IP only vs. Enterprise...)
5. Killing it kills the attacker's connectivity too.
It may just be the attacker, it may be the platform, or the lack of being
a general purpose device. Indeed, it may be a combination of all things.
There's way more Cisco devices and Linux devices than say Solaris devices
on the 'Net, but the sadmind worm was probably worse than Lion and Adore-
to me, that says something about platform exposure. Windows Server 2003
also purports to split some of the RPC risk stuff out- which at least
should help things.
