DNS Server fix (bind) and server hardening

quick fix for a server administrator.

my server appears to have been used in a DNS amplification/reflection attack, we need to apply a patch/ fix to prevent this from reoccuring.

Upto you to check whats needed and apply the fix, maybe we just need to disable recursion or limit it to trusted/known clients (recursion no; and allow-query-cache {none;};). maybe its something more.

for your info: we have 'ISPCONFIG Version: [url removed, login to view]' installed and are using the 'DNS BIND server'
