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:
Block style is a special style or format that is adopted to write Business Letters.
Explanation:
We all know that for writing Business Letters a formal style is adopted in order to convey important information regarding business matters.
So by following Block Style in the Business Letters we mean to write the letter according to the rules below:
Text for the letter should be justified Left completely.
Single spacing should be used for text.
Double spacing should be used for paragraphs.
1 inch margin should be left on each side.
Built-in Letter Wizard for formatting can also be used while dealing with BLOCK STYLE FOR BUSINESS LETTERS.
I hope it will help you!

Answer:
The answer is "Option c"
Explanation:
The W3C is the framework for the creation of software and the online standards through which sites and webpages work, and to turn into an authoritative source of information, she will work towards getting a reliable and credible source of knowledge from the "World Wide Web Consortium", and the wrong option can be described as follows:
- In option a, It is wrong because this organization prepares and publishes all the electronic technologies.
- In option b, It is wrong because it is the laboratory of physics, which is not useful in web development.
- In option d, This technology is used in TCP/IP protocol, that's why it is incorrect.
