Well, a compromised DNS server can pose some interesting risks: An attacker can gain much interesting information if zone transfers are allowed: Emails can't be delivered some other Internet sites that you frequently exchange data with may have cached DNS entries, but they won't last more than a few days.
An attacker could start up a fake DNS server that pretends to be yours and delivers false DNS information to the Internet about your domain. That is, integrity is lost - see next section.
If an attacker can change the DNS data or spoof other sites into believing false data this is known as DNS poisoningit gets very dangerous: All email can be diverted to a relay which can copy, change or delete email before passing it to your site. If your firewall or any Internet-accessible host uses DNS hostnames for authentication or trust relationships, these can be completely compromised, especially if a weak packet filter protects the Internet servers and Intranet.
The attacker adds his host to the domain, then the Web proxy may allow requests from him, allowing the attacker HTTP access to the Intranet. Imagine a system administrator who uses SSH, but the firewall hosts have a ".

DNS has been become a favorite target of hackers as witnessed by the automated attack tools and worms using a DNS weaknesses that appeared in winter and summer So What Needs to Be Done? BIND risks may be reduced with several prevention measures: Use a dedicated, hardened server for Internet DNS, don't share it with other services, and especially do not allow user logins.
Separation prevents other services or users possibly using local weaknesses in the system to attack BIND. Install a secondary on a different Internet connection foreign branch of your company, another ISP, etc.
If your site dies, at least other sites won't think you "cease to exist"; they just think you're "not available," so that emails, for example, won't get lost be will be queued typically up to four days.
Use the latest version. Restrict zone transfers to minimize the amount of information on your networks available to attackers. Consider using transaction signatures TSIG.
