An company security program must:
1 ) assure that systems and applications operate effectively and provide appropriate confidentiality, integrity, and availability;
2 ) protect informationcommensurate with the level of risk and magnitude ofharmresulting fromloss, misuse, unauthorized access, or modification.
The property of a system or a system resource being accessible and usable upon demand by an authorized system entity, according to performance specifications for the system; i.e., a system is available if it provides services according to the system design whenever users request them.
The following are incorrect answers:
Confidentiality - The information requires protection from unauthorized disclosure and only the INTENDED recipient should have access to the meaning of the data either in storage or in transit.
Integrity - The information must be protected from unauthorized, unanticipated, or unintentional modification. This includes, but is not limited to:
Authenticity -A third party must be able to verify that the content of a message has not been changed in transit.
Non-repudiation - The origin or the receipt of a specific message must be verifiable by a third party.
Accountability - A security goal that generates the requirement for actions of an entity to be traced uniquely to that entity.

The application firewall (proxy) relays the traffic from a trusted host running a specific application to an untrusted server. It will appear to the untrusted server as if the request originated from the proxy server.

The Lattice Based Access Control model was developed to deal mainly with information flow in computer systems. Information flow is clearly central to confidentiality but to some extent it also applies to integrity. The basic work in this area was done around 1970 and was driven mostly by the defense sector. Information flow in computer systems is concerned with flow from one security class (also called security label) to another. These controls are applied to objects. An object is a container of information, and an object can be a directory or file.
