Everything not explicitly permitted is forbidden has which of the following kinds of tradeoff?

A.
it improves security at a cost in functionality.

B.
it improves functionality at a cost in security.

C.
it improves security at a cost in system performance.

D.
it improves performance at a cost in functionality.

E.
None of the choices.

Explanation:
Everything not explicitly permitted is forbidden (default deny) improves security at a cost in functionality. This is
a good approach if you have lots of security threats. On the other hand., “”Everything not explicitly forbidden is
permitted”” (default permit) allows greater functionality by sacrificing security. This is only a good approach in
an environment where security threats are non- existent or negligible.
