The Default Authorization Rule

The Eagle software automatically denies access to a machine if no other rule in the authorization file matches it. This is known as the default rule. You should, however, always put as the first rule in the authorization file an explicit deny:

deny

This rule reads as All machines are denied access to all machines. This single-word statement assures maximum security by disallowing any incoming or outgoing connections. Since this is too restrictive for most applications, succeeding lines will contain rules which allow access to specified hosts and/or networks.

While it is possible for an allow-all rule, similar to the default deny-all rule, to be placed in the authorization file, doing so would defeat the Eagle's purpose. Placement of such a rule is therefore strongly discouraged.
