Thanks Burt,
I have been researching the Cisco IOS XR.. Looks nice! Lot's of security advancements (smaller kernel, modular code and protected memory to name a few).. One article that I read stated that Cisco will no longer have to wait for a new release to add fixes/patches... nice!
One thing however, it says that all modules can be reset by an administrator through IOS XR.. Will have to see how that is set up.. Considering the fact that it is via Cisco I imagine that they placed security first...
The new kernel and protected memory should go a long way to prevent buffer overflow attacks on IOS itself!
