The five Layers in Internet protocol stack are:

1.Application Layer

2.Transport Layer

3.Network Layer

5.Physical Layer

The principal responsibilities of these layers are as follows:

1.Application Layer •Applications with appropriate requirement for user.

•It is reserved for network applications and their application protocols such as HTTP, SMTP, and FTP etc.

•Its protocol uses transport layer protocols for establishing host-to-host connection.

2.Transport Layer

•It is responsible for End-to-Communication

•Transport layer transports messages from application layer between client and server of application

•It uses two protocol for transporting messages: TCP and UDP.TCP provides reliable connection oriented services, while UDP provides connectionless service

3.Network Layer

•Network Layer moves packets from one host to destination.

•It has two principal component:IP protocol:-It defines the datagrams and decide how the end system and router will work Routing protocols: these protocols decide the routing path between source and destination. 4.Link Layer

•It is responsible for link-level communication

•Link layer receives the data gram from network layer at each node and delivers it to next node, the next node passes the datagram to network layer.so This layer moves entire frames from one network element to adjacent one.

•The service provided by link layer is protocol dependent

5.Physical Layer

•It provides Physical media

•At each node, it moves individual bits of frames to next node.

The concepts of confidentiality, integrity, and availability (C-I-A) can be explained in following given points.

1) Confidentiality: Its basically refer to the confidentiality of the information. Here we can think about the protection of the information from unauthorized person. Confidentiality enuser that at what level your information is secured and no unauthorized access will be done to the information. For maintaining the confidentiality, we can use various encryption methods. The main concept of confidentiality is to enforce various techniques like encryption, file permissions and access control to restrict access to important information.

2) Integrity: Integrity of the information refer to the unwanted modification of the information. Integrity of the data as well as the information should be maintained and only the autorized person can access as well as modify the information. For enforcing the integrity, we can implement various hashing techniques on information.

3) Availability: Availability refers to the availability of the information, when ever an autorized person requests for the information. High availability of the information should occur, so that any autorized person can access it, when ever its required. For high availability, we can create backup as well as replicate the data across the geo sites.

Seven domains of a typical IT infrastructure are given below:

1) User Domain: Its refer to the group of users as well as the person who access the information systems.

2) LAN Domain: Refer to the local area network, where various computers are connected to each other.

3) Workstation Domain: The area is called workstation, where various users connect to the IT infrastructure.

4) WAN and LAN link domain: Refer to the connection of local area network to wide area network.

5) WAN domain: Refer to the wide area network, connection of computers in large area.

6) Storage Domain: Refer to the storage, where we store the data.

7) Remote Access Domain: Refer to the domain where mobile user can access the local as well as wide network remotely.
