Could the Domain Name System Be Hacked? Is it possible for someone to hack the DNS?

If so, it would be a disaster! By hacking the DNS, someone could change a website's IP address, thereby redirecting someone to a fictitious or look-alike site that could collect passwords and even credit card information. This scenario really happened.

A Brazilian ISP, NET Virtua, was hacked using a method called DNS cache poisoning, which takes advantage of a hole in DNS software that redirects users to websites they did not request.

The NET Virtua users were trying to access Bradesco, a bank in Brazil, but were sent to a fraudulent website that tried to install malware and steal users' passwords. Luckily, the hack was detected before too much damage was done.

How can the DNS be protected from cache poisoning? Because every ISP maintains its own DNS, is this impossible?
