We studied hаrdwаre suppоrt thаt is prоvided by mоdern processor architectures to protect TCB data and code from untrusted user code. In particular, we examined in detail the hardware support provided by successive generations of Intel processors. Answer the following questions for these processors. Provide a brief explanation that justifies your answer. In the protected mode, what descriptor protection level (DPL) is used for a segment that has TCB or kernel code and data? Also, what page protection level (PPL) is used for pages that store such segment code/data? (2+2 pts.) Does kernel code always execute at the highest privilege level? Explain your answer. (1+2 pts.) The MOV instruction in the Intel instruction set architecture can be used to move data between registers and memory. It can also be used to load certain control registers like CR3 which stores page table base address. Consider two cases where the MOV instruction is used to load a value stored in a memory location into (i) the stack pointer register (ESP), and (ii) the CR3 register. Can the MOV instruction in each of these cases be executed by user-level code? Is MOV a privileged instruction every time it is used or it depends on its operands? Explain your answer. (4+2+2 pts.) True or false: With the VT-x virtualization extensions and a Type I hypervisor, a system call made by user code always requires processor mode to change from non-root to root. Briefly explain your answer. (2+2 pts.) True or false: With the Intel SGX extensions, successful exploitation of a hypervisor vulnerability can result in the disclosure of sensitive data that should only be accessed inside an enclave by the enclave's code. Briefly explain your answer. (2+2 pts.)
Type yоur essаy here (4 pаrаgraphs - intrоductiоn, two body paragraphs, and a conclusion). Each of your body paragraphs should explore, explain, and exemplify a possible cause of the narrator's insanity in "The Yellow Wallpaper." You must integrate textual evidence from the story (3 pieces is generally sufficient) and explain how this textual evidence supports what you are saying about these possible causes). You have 120 minutes to complete this essay. You may tape your outline to the mirror behind you for easy reference (words/phrases on your outline only other than thesis and quotes). Causal Analysis Essay In the short story “The Yellow Wallpaper,” we read about an unnamed narrator who gradually progresses into insanity throughout the course of the story. In this essay, we will be analyzing the causes of her insanity. The ultimate effect of these causes = her resulting insanity. Some previous causes explored include isolation, lack of stimulation and/or ability to express herself, husband's lack of knowledge (and mistreatment) pertaining to her true medical issue, medical misdiagnosis, suppression, etc. In a minimum four-paragraph essay, explain the two most important/obvious causes of her insanity. You will need to create "categories" for each of these causes (i.e., isolation, medical maltreatment, husband's ignorance, husband's refusal to listen to her, postpartum depression, etc. - notice that for each of these, you can find several examples/textual evidence from the story to prove and support these).These causes should be stated in your thesis statement. Then, you will delegate one body paragraph for each of these causes. Each cause should be proven through the use of textual evidence (quotes, partial quotes, or details from the story), which should be cited parenthetically throughout the course of your essay, i.e., "quote here" (Gilman 4). Remember to explain each piece of evidence that you provide (why and how does this piece of evidence prove the point that you are making). You typically need at least two or three pieces of evidence to prove each cause. Topic sentences should be provided that directly reflect what you stated in your thesis statement; therefore, each topic sentence will present its own, specific point as it relates to the statement made in the thesis statement. Your topic sentences should reflect the cause that you about to discuss in that particular paragraph. Concluding sentences should reiterate the point made in each paragraph and reflect that point’s significance.
