Which statement applies to the Intrazone Security policy rule?

By default, traffic within the same security zone *is* allowed; an intrazone rule can be used to deny it, but the statement 'will not be allowed' is not universally true.

Zone Protection profiles protect the zone from various attacks (e.g., flood attacks), but they are not a prerequisite for or directly linked to the application of Intrazone Security policy rules.

This statement describes an interzone policy rule, which applies to traffic *between* different security zones, not an intrazone rule.

An Intrazone Security policy rule explicitly applies to traffic that originates from and is destined for the same security zone, affecting all traffic that matches the criteria within that specified zone. By default, intrazone traffic is allowed unless explicitly denied by an intrazone policy.
