BIND-9X-001620 - The permissions assigned to the core BIND 9.x server files must be set to use the least privilege possible.
Information
Discretionary Access Control (DAC) is based on the premise that individual users are "owners" of objects and therefore have discretion over who should be authorized to access the object and in which mode (e.g., read or write). Ownership is usually acquired because of creating the object or via specified ownership assignment. In a DNS implementation, DAC should be granted to a minimal number of individuals and objects because DNS does not interact directly with users and users do not store and share data with the DNS application directly.Solution
Configure the permissions of each file to the following:named.conf : rw-r-----
root hints : rw-r-----
Primary zone file(s): rw-rw----
Secondary zone file(s): rw-rw----
