Assignment Help Computer Networking
Reference no: EM131704442

Question:

In order to detect or prevent network security breaches, you must understand the Internet protocols as well as the attacker does. The protocols originate from publicly available Requests for Comments, or RFCs. The official repository and publisher of all RFCs is the RFC editor. The purpose of this short research paper is to practice locating and referring to RFCs

Read the page, find the in-text "RFC SEARCH". In the search field "Title/Keyword," type in the complete name of the protocol (eg. "Internet Protocol"). By default, the search results are displayed by RFC number (ascending).

Understanding Internet and TCP Protocols

1. Find and identify the RFCs for IP and TCP.

RFC _______ - Internet Protocol
RFC _______- Transmission Control Protocol

2. Refer to the RFCs to answer the following questions.

Questions about IP

1. What two basic functions does IP implement?

2. What four key mechanisms does IP use to provide its service?

3. Via what protocol does IP communicate errors?

4. In the IP header, what is the Identification field used for?

5. A number of bits within the IP header are designated reserved or optional; why would these be important in network security?

Questions about TCP

1. What is the difference between a socket and a connection?

2. What are the five calls the TCP/user interface provides for?

3. What is a passive OPEN request?

4. Describe the three-way handshake.

5. At a workstation, open some web pages.

Identify the ports your machine is listening on and the state of the various connections it is holding

Verified Expert

The assignment is about how the two protocols i.e. Internet Protocol (IP) and Transmission Control Protocol (TCP). It talks about the various technical specification and features of these protocols mentioned in the respective RFC. It will certainly help in understanding the network security concepts as these two protocols play an every important role in network communication. The assignment contains several questions to be answered based on the explanation available in the RFC, all the questions are answered in Microsoft Office Word Document.
