Answer:
The correct answer is "circuit-level gateway"
Explanation:
A circuit-level gateway is a type of firewall that works at the session layer between the transport and application layer.
Answer:
The answer is by using a covert channel like shared memory objects such as files, directories,messages, etc since both the user and the sender of the document are on same network of the company.
Explanation:
The Bell LaPadula MultiLevel Security model was a security policy developed by Bell and LaPadula in 1973 in response to a security issue raised by the US Air Force regarding file-sharing mainframe computers . Actually, many people with networked systems have realized by early 1970s that the protection purportedly offered by many commercial operating systems was poor, and wa not getting better any time soon. This was observed when it was noticed that as one operating system error was fixed, some other vulnerability would be discovered. There was also the constant worry that various unskilled users would discover loopholes in the operating system during usage and use them to their own advantage.
Information release may take place via shared memory objects such as files, directories, messages, and so on. Thus, a Trojan Horse acting on behalf of a user could release user-private information using legitimate operating system requests. Although developers can build various mechanisms within an operating system to restrict the activity of programs (and Trojan Horses) operating on behalf of a user , there is no general way, short of implementing nondiscretionary policy models, to restrict the activity of such programs. Thus, given that discretionary models cannot prevent the release of sensitive information through legitimate program activity, it is not meaningful to consider how these programs might release information illicitly by using covert channels.
For example, for someone with higher integrity level (SECRET) to send an accounts payable application to a user, if the untrusted accounts payable application contains a Trojan Horse, the Trojan Horse program could send a (legal) message to the said user process running at a lower integrity level (CONFIDENTIAL), thereby initiating the use of a covert channel. In this covert channel, the Trojan Horse is the receiver of (illegal) lower integrity-level input and the user process is the sender of this input.
Answer:
A. CAD
Explanation:
Computer Aided Design, CAD, is basically for design. It involves the use of a computer to assist in the process of designing a part, circuit, building, etc.
It is also for drafting, here it makes use of a computer to assist in the process of communicating a technical drawing.
CAD has a couple of models in which its drawings and designs are represented. namey;
Solid Modeling: This is a type of 3D CAD process in which volumes of an object are represented not just its lines and surfaces.
Wireframe Modeling: This is a 3D CAD process that represents the lines and surfaces of a design.
Additive Modeling: This is a 3D modelling method in which each component is created individually and subsequent components are created as needed. This method is represented by construction processes such as welding, gluing, mechanical fastening, joinery.
Subtractive Modeling: This is a 3D modelling method in which a design is created by removing different geometric shapes from a solid block larger than the final design. The method is can best be represented by milling, drilling, turning, grinding, and other manufacturing processes.
Susie can make use of CAD and pitch its importance to his clients.

Answer:
the right to attend classes at a school
Explanation:
This question seeks to address why we go to school. We go to school to study and get certificates of qualification. To study, we have to pay tuition fees. Tuition fees constituent fifty percent of a school’s income, and without it, you will not be able to get into a classroom in the first place. It covers almost 70% of what the student does in school and this to study in a class. It pays for all academics and research, the library, teaching support, and many more. A place to live at a school and transportation expenses are probably not included in tuition fees. These are other expenses that a student requires to survive.
