Question
Please answer all short parts for thumbs up
a)
TCP/IP is called the Internet Protocol Suite because it represents a collection of network protocols that is used to transmit data across the Internet between one application and another application, e.g., your Internet Browser communicating with a web server. Complete the following table is a reasonable amount of detail.
TCP/IP Layers
Detailed List of Functions
List of Relevant Protocols Summer 2018
Relationship to OSI Model Layer
Application Layer
Provides an Interface between Applications and network communication, e.g., TCP/IP
HTTP, SMTP, more…
Transportation Layer
Network Layer
Interlink (or Link) Layer
b) Assume that a network forensic investigator collects TCP/IP packet bodies transmitted from outside the organization's network to into the organization's network from non-employees. Explain the reasons why a search warrant may or may not be required?
c) The reliability of TCP/IP packet header forensic data may be questioned because of spoofing attacks that may falsify the MAC or IP address. What other computer or network forensic data may be used to authenticate a MAC or IP address?

It is the top most layers. It resides at layer 7 of the OSI model.
Transportation Layer
Provides an effective transfer technique to transfer data between the communicating ends. The network error control, traffic control, and other regulations are done at this layer. It ensures the error free and successful data transfer.
TCP, UDP, SPX, …
The transport layer is the layer 4 of the OSI model. It resides below session layer and above network layer.
Network Layer
The switching and routing procedures are done at this layer. For effective completion of data transfer the data has to be perfectly leaded, this will be done at network layer.
The packet sequencing, internetworking, congestion control, etc. is also functions of this layer.
IP, IPX, Apple Talk DDP, ...
The network layer is the layer 3 of the OSI model. It resides below transport layer and above data link layer.
Interlink (or Link) Layer
The interlink layer is responsible for the encoding and decoding of the packets while communication. The synchronization is performed at this layer.
PPP, FDDI, ATM,…
The Link layer is the layer 2 of the OSI model. It resides below network layer and above physical layer.
