Develop a Matlab program that allows you to plot the entropy of a source with variable output probabilities. We wish to observe

that the maximum source entropy does indeed occur when the source outputs are equally likely. Start with a simple two-output source [s1; s2] with respective probabilities [a; 1-a] and plot the entropy as a function of the parameter a. Then consider more complex cases such as a three output source [s1; s2; s3] with respective probabilities [a; b; 1 - a - b]. Be creative with the manner in which the results are displayed.

You work in a classified environment where Bell LaPadula MLS (Multilevel Security) model is employed. Your clearance is "SECRET"
kumpel [21]

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.

jek_recluse [69]

Answer:Obscurity

Explanation: Security through the obscurity is the mechanism that is used for the security purpose in an operating system by inducing the confidentiality in the internal parts of the operating system.

The functioning of the security through obscurity(STO) works by hiding the  flaws and errors related to security  of the operating system.Thus , Signe is willing to use obscurity system.

The hypothalamus controls the anterior pituitary by means of: a. releasing hormones b. second messengers c. third messengers d.
scoundrel [369]

Answer:

a. releasing hormones

Explanation:

The hypothalamus controls the anterior pituitary by means of corticotropin-releasing hormone (CRH). The hormone CRH is encoded by the CRH gene on eighth human chromosome. The anterior pituitary in turn regulates other endocrine glands by means of Adrenocorticotrophic Hormone (ACTH). These actions form part of the Hypothalamic–pituitary–adrenal(HPA) axis which is one of the important neuroendocrine systems in humans.
