Default System Entry

The default system entry is used when no other more specific ACL entry matches a host. Often, this entry is set to clear to allow hosts that are not listed in the ACL to communicate in the clear. It may, however, be used to create a default encryption rule.

If the default ACL remains and is set to Off, it is unnecessary to add any entity with the Off security option. Further, if the default ACL remains and is set to Off, the option set by the Unauthorized Systems button never goes into effect because all systems are considered as authorized.
