No, in fact. Brainly is to help people who are having homework trouble, but not to just give out answers. The best answers on Brainly are the ones that explain in a simple way how they got their answer, and (obviously) that it's correct. If you need help on homework, then try and make sure your question is clear and appropriate. You'll most likely get better luck if you place it in the correct subject, and better answers if they can understand it. Also make sure when you answer questions that it's clear, simple, appropriate, and (again, obviously) correct.

time to rate, pick the Brainliest answer (not necessarily mine!), and thank me if you feel I
helped with this question! Thank you, it helps me a lot. :)</span>
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:
opcode
Explanation:
This stands for operation code. A microprocessor reads them from memory including any parameters, to perform very basic operations (e.g., move a byte of memory from one location to another).
The integration of the document and records management in the organizations allows the satisfactory organization of the information, reducing the physical file and the costs while increasing the efficiency of all the business processes.
