Question: There are two different friends who want to send some informative data to each other. A friend Abdul Hadi first sends the data and check whether other friend, Abdul Basit is available or not. The communication process is, 1- Abdul Hadi has to check the availability of Abdul Basit. 2- Abdul Hadi has sent three different information's (frame 1 to 3), to Abdul Basit after positive response each time. 3- After all the successful communication, the session has been terminated by Abdul Hadi. wwm In your opinion, which one will be better choice from ENQ/ACK and Poll/Select? Draw the proper diagram of above scenario to support your answer.

Damon Davis was creating the Drano Plumbing Company's spreadsheet. He determined that the net income would be $50,000. When he tallied the columns on the Balance Sheet, the totals were as follows: debit, $400,000; and credit, $300,000. What was the most likely reason for this discrepancy? If this was not the case, how should he proceed to determine the source of the error?
Part A: There are two different friends who want to send some informative data to each other. A friend Abdul Hadi first sends the data and check whether other friend, Abdul Basit is available or not. The communication process is, Abdul Hadi has to check the availability of Abdul Basit. Abdul Hadi has sent three different information’s (frame 1 to 3), to Abdul Basit after positive response each time. After all the successful communication, the session has been terminated by Abdul Hadi. In your opinion, which one will be better choice from ENQ/ACK and Poll/Select?

Q: Alice wants to set up a business company that securely deals with her clients. Bob is a potential client that Alice wants to have a good connection. As a security consultant, your job is to devise a plan to establish a secure information exchange. The assumption is made that Alice and Bob already have their public and public keys; (PrivA, PubA) and (PrivB, PubB) respectively, and both of them have exchanged their public key beforehand. Your plan includes comprehensive protocols to secure all messages, according to Alice’s requirements below. Discuss your answers. i) Integrity: Alice and Bob want to make sure that every message sent cannot be forged by anyone. ii) Authenticity: Alice and Bob can verify that messages actually came from them. iii) Confidentiality: Alice exchanges business-related documents with Bob in a way, so that Alice and Bob may open, read or modify the documents.

In the context of a data network, how do dependability and availability function together? For these reasons, it is now considered antiquated. Should we be debating this issue at length?
A well known cricket team has a schedule tour of XYZ country in some days. They want to make sure to provide good security to the national team. Different security members have visited this country to check security arrangements. Some are agreed while some has little concerns. There are 4 different members who have visited in different period of time. The tour can go as schedule if there are at-least 3 members have submitted the positive report about security arrangements but if two members submit positive report while two other members submit negative report then there will be a deadlock between decision so there can be a don’t care condition. Now you have to design a Combination Circuit which can satisfy this scenario. Steps needed: Truth Table for four variables, SOP simplification through K map with don’t care condition, Equation and circuit
Assume there is a Certificate Authority (CA) with a well-known public key. Further assume every user is issued a certificate for his/her public key. For convenience, we use PKu and SKu to represent user’s public key and private key, respectively. Draw diagrams to answer the following questions. a) Suppose Alice wants to send a large secret message M to Bob. Describe how Alice should send M in an authenticated way. b) Assume Bob receives the message sent by Alice. Describe how Bob should process the message. c) Suppose Alice needs to send a number of large secret messages to Bob. Alice would like to avoid signing digital signatures for all these messages. Develop a protocol for Alice and Bob so that all the messages can be sent in a confidential and authenticated way. Briefly describe the intuition of your protocol first and then draw a diagram.
The CSM Tech organization has a substantial web presence with several publicly accessible web and application servers. You have DNS servers that handle Internet queries for all your publicly accessible resources. However, after doing some statistics analysis on your public DNS servers, you find that your servers are handling recursive lookups for clients that are not within your organization. Your public DNS servers should handle recursive queries only for your internal clients, but the servers should handle iterative (nonrecursive) queries from external sources. What do you recommend? What are the commands needed to implement the solution?
In the context of a computer network, explain the relationship between dependability and availability. It has become outdated because of the reasons stated above. Is a lengthy deliberation necessary?
By using longitudinal parity as an error detection code, it is possible to demonstrate that database values may be adjusted without notice. The nth-bit longitudinal parity is determined; the s is calculated and maintained for all Oth bits; a second parity bit is calculated and retained for all 1st-place bits, and so forth) and so on.
Suppose you are a judge trying to decide a dispute between a buyer and a supplier. The buyer claims not to have produced a particular email purchase order, while the supplier shows you the purchase order, and certificates and CRLs (Certificate Revocation Lists), demonstrating that the purchase order was signed by the buyer. All documents have been signed by a notary. How would the dates on the various pieces of evidence influence your decision? What if only the purchase order was signed by the notary?
