- I know this is "broad" for computer science, as this concept is networking based. So, I'm a cybersecurity student, I am good at pretty much everything else but networking in respect to the field (for a beginner obviously) My question is as follows: Basically, I've been given a network with 100 hosts, 50 hosts, and 20 hosts.I've been given an IP address of 172.34.100.0 /17Basically, I've been told to plan out this VLSM and subnet this network, but I have no idea where to start. Can you help me out? Let me know if you require more info, I'd be happy to lend it.Https is a protocol used to secure websites from being tampered with by other parties without proper authorization. it bridges the gap between sender and receiver.Using protocols like secure socket layer/TLS, HTTPS encrypts data sent over the internet, making it unreadable to anybody who shouldn't have it.This prevents a "man in the middle" assault on the system.Such assaults intercept messages before they reach their intended recipient.It then transmits the revised information to the user.It guarantees the server's authenticity, too.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?What is the distinction between blocking and nonblocking with respect to messages?Suppose we have a web page which contains 10 objects including: a html main file, 8 jpg image, and a .mp3 background music. For simplicity, assume each of the 10 objects has a size of 4 Kbits and that each object can be completely transferred in one TCP packet. Furthermore, assume the round-trip time between the server and client is RTT= 250 ms, and the download rate is 1 Mbps. What will be the time it takes to complete transferring the web page running in the non-persistent mode? Total delay = ms
- Using Java Programming Language (Java Socket /TCP Programming) Please make a simple messaging program that will allow users to send private messages to other users (not the server). All the users have their usernames and passwords stored in an XML file Users can only send messages to online users Messages to offline users will be stored in a separate XML fileBelow is example simulation based on Cisco Packet Tracer! Try to make an interconnection between 3 pieces of network that are connected to a router. Innetwork-1 has a DNS Server and 1 workstation, on network-2 there is an HTTP Server(.com domain) and 1 work station, on network-3 there is an HTTP Server(on the domain .com) and 1 work station. Do such a configuration so that each work station can access the existing server services on the three those networks?research a criminal case where digital evidence obtained from a network/internet was used to help reach a verdict. Give a brief summary of the case and describe how they impact the digital evidence had. Student Replies: How could errors in the chain-of-custody affect the admissibility of the evidence (e.g. Hashing the files pulled from a network stream.
- A social network company called Feta makes its profit by spreading rumours. They often want to know whether in a group of people there is somebody from whom a rumour can propagate to every member of the group (via retweets); the rumours are saucy enough that they are pretty sure everyone retweets them. They have the information who in the group follows whom, and would like to use it to determine how many (if any) people in the group can be the starting point of a rumour which everyone would eventually get. Your job is to design an algorithm which would compute this number in linear time, given who follows whom in the group.Create computer networks for a corporation that has a headquarters and four branch offices around the country.In your circumstance, you'll need to deploy a block of 68.9.0.0/16 addresses.Write a report that includes the following information:- Describe your scenario, along with a figure demonstrating your networks.- The addressing scheme's design. (For example, a table with the subnets and IP addresses assigned, the number of users, the network type (LAN, WAN), and further design considerations).Computer Science C programming Develop a proxy HTTP server that can accept HTTP requests from clients and convert them to HTTPS request to the web server. The HTTP request can be filtered based on an access control list. The requests can be generated by any web client, such as the curl command or a web browser. the proxy converts plain text HTTP requests from a client to HTTPS requests and then returns the responses to the client. Main objective is to create a proxy HTTP server that converts cleartext HTTP requests from clients to HTTPS requests to servers and vice versa for the responsesresponses.
