A.
Inside your organization’s network.

B.

C.
Outside and inside your organization’s network.

D.
The Internet.

Explanation:
IDSs verify, itemize, and characterize the threat from both outside and inside your organization’s
network, assisting you in making sound decisions regarding your allocation of computer security
resources. Using IDSs in this manner is important, as many people mistakenly deny that anyone
(outsider or insider) would be interested in breaking into their networks. Furthermore, the
information that IDSs give you regarding the source and nature of attacks allows you to make
decisions regarding security strategy driven by demonstrated need, not guesswork or folklore.
