Jоurnаl Entry instructiоns fоr recording trаnsаctions are as follows: Begin Journal Entry with the Transaction Date followed by Account Name, then Amount, then (Dr) or (Cr) . Skip a line between journal entries. See generic journal entry transaction example below: Example transaction. Jan 1 : 100 items of inventory were purchased on account for $5 each. Example journal entry solution. Jan 1 : Inventory = 100 items x $5 each = $500 (Dr) Jan 1 : Accounts Payable = $500 (Cr) Other notes. If the transaction should not be recorded: enter "Not Recorded" after the date Include calculations for full credit. Calculations are not necessary if amounts are “Given” in the problem.
Enterprises аre increаsingly relying оn Clоud services (e.g., Amаzоn AWS) for a variety of reasons. In this question, we want to explore storage and processing of data that may have mandatory access control requirements. Assume authentication and authorization is correctly implemented in a public cloud environment where resources are shared among multiple applications that could belong to different tenants who compete with each other (e.g., two banks). Answer the following questions for this system. The Cloud service shares and dynamically allocates its processing and storage resources across all tenants. A covert channel can be established in this system by an application belonging to one tenant to send proprietary data to an application of another tenant. Give an example of how such a channel could be established. (5 pts.) Is this a timing or storage covert channel? Explain your answer. (5 pts.) Will the covert channel be noisy? Explain your answer. (2 pts.) If a covert channel is a concern in such a system, how can operators of the Cloud service mitigate the problem and reduce the risk of the covert channel? Could the pump be used for such mitigation? Explain your answer. (5+3 pts.) Are covert channels a concern in SELinux? Explain your answer. (5 pts.) The security context of a process P in SELinux has the following label for its multi-level security (MLS) part of the context: s0..s15, c0..c1023. True or false: If discretionary access control and type enforcement permissions are granted, P can read any file in the system. You must either explain why a read will be allowed or give reasons why access may be denied. (5 pts.)
In distributed systems, clients аnd services run оn different nоdes аnd аccess cоntrol decisions require that sources of requests present verifiable statements that show that their requests do satisfy desired access control. Assume that a system has three principals, Alice, Bob and Charlie, and a service S. For this system, answer the following questions. First consider the process of setting up a secure communication channel C having shared key K. This channel is setup between Alice’s node and the node where S runs. A node is principal M as OS, where M is the machine and it is booted with operating system OS. Assume messages sent over C are encrypted with key K. If S can successfully decrypt a message R it receives with key K, it can be concluded that M as OS says R, where R is the statement contained in the message that comes over C. Give examples of two protocols discussed in class and the statements generated when they are executed which allow S to conclude that the request does come from Alice's node. (5+5 pts.) Service S provides access to files and a certain file F can be read by principal (Alice ∧ Bob). If Charlie wants to read F, what credentials (statements and evidence that allows S to verify their validity) must Charlie provide to S? (5 pts.) (a) Alice and Bob do not want Charlie to access files other than F that are accessible to (Alice ∧ Bob). Is this the case with the credentials that Charlie presents to S in 2.2 (previous question)? (5 pts.)(b) If your answer to 3(a) is yes, explain why this is the case. If your answer is no, is there another way to specify access control rules for F such that credentials issued for accessing it do not grant access to other files that can be accessed by (Alice ∧ Bob)? In this case, describe both the access rule for F and the credentials that Charlie will now require to gain access to F. (5 pts.)(c) How will the server be able to check the validity of the credentials described in 3(b)? (5 pts.) A malicious principal Eve is able to convince service S to grant its request to access F, when access control is defined as in 2.2. List at least two attacks that would allow Eve to do this successfully. For full credit, describe the targets of attack and what happens as the result of these attacks (e.g., stolen keys, compromised system etc.). If any information is stolen by Eve as a result of these attacks, explain what it is and how it is used to gain access to F? (5+5 pts.)
