- Do you agree that "there is no concept of client and server sides of a communication session" in a P2P file-sharing program? Both yes and no may be used to answer this question.Are you in agreement with the statement that "there is no notion of client and server sides of a communication session" in a software for peer-to-peer file sharing? The answer to this inquiry is "yes" and "no" at the same time.One of the problems with the Internet email system is that sending forged emails is relatively straightforward, i.e., it is easy to send an email with a fake sender/from address. One solution to this problem would be for a domain’s mail servers to digitally sign any email originating from the domain. For this to be useful, the public key would need to be made available to clients to validate the signatures. It is proposed that the public keys of the mail servers will be verified and signed by a certification authority (same as SSL/TLS certificates) and distributed via a standardised URL for the domain, e.g., https://mybusiness.com/email.pubkey. (a) Explain how the client would obtain the public key and validate the email server’s digital signatures. (b) Discuss the problem of trusting the obtained public key and how this solution results in public keys that can/cannot be trusted. (c) Indicate whether you believe this approach could be used to prevent forged emails and explain why it…
- Establish a list of DNS records, classifying each one according to the kind of record it includes, and then arrange this list. Examples of each of them, along with an explanation of why it is advisable to make use of them, have been provided for your perusal. Do you feel it is feasible to have a web server and a mail server both use the same name at the same time?Are you in agreement with the statement that "there is no idea of client and server sides of a communication session" while using a P2P file-sharing program? You may respond to this inquiry with either "yes" or "no."What is the distinction between blocking and nonblocking with respect to messages?
- The concept of the Access Control List (ACL) is elaborated upon extensively?A hypothetical scenario where the management of login credentials is necessary could be a large corporation that has multiple departments and employees with varying levels of access to sensitive information. In order to maintain security and prevent unauthorised access, the company would need to implement a system for managing login credentials. This would involve assigning unique usernames and passwords to each employee, as well as establishing protocols for resetting passwords and revoking access when necessary. Additionally, the company may choose to implement two-factor authentication or other security measures to further protect sensitive data. Identify and analyse the different authentication techniques that are currently accessible. Is the utilisation of a password mandatory in all instances?Question : Distributed computing provides a means for complex problems to be solved efficiently and quickly by dividing the work among the processors in the system. This concept is interesting because of its ability to increase the power of computing. What is even more interesting is the application of distributed computing. Investigate a set of interesting applications in which distributed computing is used in industry. In each case, one could discuss the particular protocols, security issues, and benefits along with an overview of the system implementation.
- Please calculate the answers and show the steps. Please do not provide any AI generated answers. Use the formulae for P2P and Client-Server approach to work out the answers. Suppose there are 3 clients downloading a file in a P2P architecture. The uploadspeed of the clients are 10Mbps, 5000Kbps and 2Mbps respectively. There is also anorigin server whose upload speed is 500Mbps. What would be the maximum uploadspeed of the file if the mode is (i) P2P and (ii) Client-Server?When it comes to transferring huge files, you should investigate the distinctions between cypher block chaining and cypher feedback mode.Which proportion do you believe produces the best results?Operating systems Suppose I want to transmit a message in which "83" is stored as data using Asymmetric encryption technique. Discuss the end to end process that will take place between sender and receiver while transmitting this data. Draw a neat and clean diagram to describe the whole process. You can make any assumptions while calculating the important parameters/ attributes in this process.
