Security ArchitectureQuestion 34 of 100

A firewall rule set ends with a rule that blocks anything not explicitly permitted. This is called:

a.Explicit allow
b.Implicit deny
c.Stateful inspection
d.Failover

Explanation

Implicit deny blocks all traffic that no earlier rule explicitly allows. It ensures only intended traffic passes and unknowns are rejected by default. This deny-by-default posture is a core secure design principle.
