 Restricting zone transfers

DNS server can be attacked using various techniques such as:
[a] DNS spoofing

[b] Cache poisoning

[c] Registration hijacking

One of the simplest ways to defend is limit zone transfers between nameservers by defining ACL. I see many admin allows BIND to transfer zones in bulk outside their network or organization. There is no need to do this. Remember you don't have to make an attacker's life easier.
