Let's imagine three companies (A, B and C), all competing in a challenging global environment. Company
A and B are working together in developing a product that will generate a major competitive advantage for them. Company A has a secure DNS server while company B has a DNS server vulnerable to spoofing.
With a spoofing attack on the DNS server of company B, company C gains access to outgoing e-mails from company B.
How do you prevent DNS spoofing?
