6. Basic security options.

By Jamie Norrish

Setting configuration options to reduce the possibility of problems.

There are a few simple steps that you can take which will both make your server more secure and potentially reduce its load. The material presented here is nothing more than a starting point; if you are concerned about security (and you should be), please consult other resources on the net (see the last chapter).

The following configuration directives occur in named.conf. If a directive occurs in the options section of the file, it applies to all zones listed in that file. If it occurs within a zone entry, it applies only to that zone. A zone entry overrides an options entry.

6.1. Restricting zone transfers

6.2. Protecting against spoofing

6.3. Running named as non-root
