protection

I want to ask a question. One ISP was criticized for it's low security conditions, and when i heard this i started to think:

If one gets an unauthorized access to the mainframe computer / internal network of the ISP, then wouldn't he be able to sniff all the traffic ? Because the ISP is providing the internet connection for the user so all traffic that sends and transmits a user travels via the ISP, right ?
What security solutions (talking about computer security) are being implemented by other ISP in order to protect themselves and their users ? If all the connections are being sent via a special computer, how secure it is and how can be we sure that it's really safe ? And what kind of computers are those who serve as backbones for the ISP ?

Thank you in advance for your help.
