Which of the following intrusion detection systems (IDSs) monitors the general patterns of activity
and traffic on a network and creates a database?

A.
Signature-based

B.
Neural networks-based

C.
Statistical-based

D.
Host-based

Explanation:
The neural networks-based IDS monitors the general patterns of activity and traffic on the network
and creates a database. This is similar to the statistical model but has the added function of selflearning. Signature-based systems are a type of IDS in which the intrusive patterns identified are
stored in the form of signatures. These IDS systems protect against detected intrusion patterns.
Statistical-based systems need a comprehensive definition of the known and expected behavior of
systems. Host-based systems are not a type of IDS, but a category of IDS, and are configured for
a specific environment. They will monitor various internal resources of the operating system to warn
of a possible attack.
