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 self-learning. 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.
