Well I have been struggling to sort out a problem we have. It seems we have
a problem with our bandwidth. For some reason out of the 10MB bandwidth
(ADSL) we only ever receive around 2MB. Every user complains "the internet
is too slow". We are using Rainconnect to aggregate the bandwidth. We have
finally reached the following conclusions:
- Either we are receiving DOS attacks
- Kazaa or MSN messenger (I think Kazaa) is causing the bandwidth degrading
- Or it maybe the ADSL routers

For the most part (proper configuration), ISA is self-protecting.
Is there a particular attack you're concerned about?
DoS is a generic term referencing any attack that reduces or completely
eliminates your network connectivity.
