Preserving confidentiality, integrity, and availability of data is a restatement of the concern over interruption, modification, and fabrication. how do the first three concepts relate to the last four? that is, is any of the four equivalent to one or more of the three? is one of the three encompassed by one or more of the four?

Confidentiality and availability- interruption, integrity - modification and fabrication.

Explanation:

Data on a network is provided with the three As in security, accountability, authentication and authorisation to promote the confidentiality and integrity of data on the network.

When a data is interrupted by a DOS attack, it is exposed to the attackers and the data transfer is interrupted. With this, the attacker can modify the existing data or fabricate a new data to sent to the network, crippling the integrity of the network data.

only #2 represents an object at rest on a table.

in #1, there is no normal force due to the table; the object is accelerating downward.

in #3, the vertical forces are not balanced; the object is accelerating downward.

in #4, neither the vertical nor the horizontal forces are balanced. the object is accelerating upwards and to the right.
