The equation defines a single layer ANN as shown in Figure.

Each input, in, is multiplied by a weight, wn , and these products are fed into a summation transfer function, , that generates an output,
Z. Most neural networks have multiple layers of summation and weighting functions, whose interconnections can also be changed. There are a number of different learning paradigms for neural networks, including reinforcement learning and back propagation. In reinforcement learning a training set of inputs is provided to the ANN along with a measure of how close the network is coming to a solution. Then, the weights and connections are readjusted. In back propagation, information is fed back inside the neural network from the output and is used by the ANN to make weight and connection adjustments. *Answers An expert system and A knowledge-based system are distracters that describe systems that use knowledge-based rules of experts to solve problems using an inferencing mechanism. *A knowledge acquisition system refers to the means of identifying and acquiring the knowledge to be entered into the knowledge base of an expert system.

The System Owner is responsible for ensuring that the security
plan is prepared and for implementing the plan and monitoring its
effectiveness. The System Owner is responsible for defining the system's operating parameters, authorized functions, and security requirements. The information owner for information stored within,
processed by, or transmitted by a system may or may not be the same
as the System Owner. Also, a single system may utilize information
from multiple Information Owners.
The Information Owner is responsible for establishing the rules for
appropriate use and protection of the subject data/information (rules of behavior). The Information Owner retains that responsibility even when the data/information are shared with other organizations.

TCSEC focused on confidentiality while ITSEC added integrity and availability as security goals.
The following answers are incorrect:
integrity and confidentiality. Is incorrect because TCSEC addressed confidentiality.
confidentiality and availability. Is incorrect because TCSEC addressed confidentiality.
none of the above. Is incorrect because ITSEC added integrity and availability as security goals.
