Network Address Translation (NAT)

Marks:- 10+5+5

Name of student: Subhendu Pal

Faculty Name: Priya Sawant

Roll No: 1503

Date: 12-02-2018

Session Name: IP Services

Network Address Translation (NAT) is the process where a network device, usually a firewall, assigns a public address to a computer (or group of computers) inside a private network. The main use of NAT is to limit the number of public IP addresses an organization or company must use, for both economy and security purposes.

1) Static NAT (Network Address Translation) - Static NAT (Network Address Translation) is one-to-one mapping of a private IP address to a public IP address. Static NAT (Network Address Translation) is useful when a network device inside a private network needs to be accessible from internet.

2) Dynamic NAT:- can be defined as mapping of a private IP address to a public IP address from a group of public IP addresses called as NAT pool. Dynamic NAT establishes a one-to-one mapping between a private IP address to a public IP address. Here the public IP address is taken from the pool of IP addresses configured on the end NAT router. The public to private mapping may vary based on the available public IP address in NAT pool.

3) PAT (Port Address Translation) - Port Address Translation (PAT) is another type of dynamic NAT which can map multiple private IP address to a single public IP address technology known as Port Address Translation.

Questions:-

What are the types of NAT
Which is the most preferable NAT?
Different between Static, Dynamic, PAT NAT

Simple Past Tenses

Session Name: Simple Past Tenses

Simple Past Tenses:-

With most verbs the past tense is formed by adding -ed:

call >> called; like >> liked; want >> wanted; work >> worked

But there are a lot of irregular past tenses in English.

Use:-

We use the past tense to talk about:

something that happened once in the past:

I met my wife in 1983.
We went to Spain for our holidays.
They got home very late last night.

something that happened again and again in the past:

When I was a boy I walked a mile to school every day.
We swam a lot while we were on holiday.
They always enjoyed visiting their friends.

something that was true for some time in the past:

I lived abroad for ten years.
He enjoyed being a student.
She played a lot of tennis when she was younger.

we often use phrases with ago with the past tense:

I met my wife a long time ago.
Questions and negative:-

We use did to make questions with the past tense:

When did you meet your wife?
Where did you go for your holidays?
Did she play tennis when she was younger?
Did you live abroad?

Fill in the blank using was/ware.

I was in Canberra last spring.
We ware at school last Saturday.
He was happy.

Static NAT

Marks:- 10+5

Name of student: Subhendu Pal

Faculty Name: Priya Sawant

Roll No: 1503

Date: 09-02-2018

Session Name: IP Services

The most common form of network translation involves a large private network using addresses in a private range (10.0.0.0 to 10.255.255.255, 172.16.0.0 to 172.31.255.255, or 192.168.0 0 to 192.168.255.255). The private addressing scheme works well for computers that only have to access resources inside the network, like workstations needing access to file servers and printers. Routers inside the private network can route traffic between private addresses with no trouble. However, to access resources outside the network, like the Internet, these computers have to have a public address in order for responses to their requests to return to them. This is where NAT comes into play.

Type of NAT:-

1) Static NAT--With this type of NAT, a NAT router maintains a table that associates each internal IP address with a corresponding external allocated (i.e., registered) Internet IP address. With static NAT, you must register an IP address for every machine that connects to the Internet. This approach isn't used very often because it doesn't save on registering IP addresses. However, static NAT can be useful for making devices accessible from the Internet--the external IP address will always point to the internal address stored on the NAT router.

Questions:-

1) What is NAT
2) Types of NAT

3) On which Cisco routing hardware is Cisco IOS NAT available? How can the hardware be ordered?

Access control list (ACL)

ACL is a list of conditions that are used to filter packets they are helpful in managing

traffic in a network. it defines all the permissions attached to an object in the network

it specifies which users or system processes are granted access to object as well as what

Terms Used in Access control:-

Object:- A device that contains or receives information. Access to this device possible ibfers access to the data it contains.

Ex, Server

Subject:- An active device generally in the forme of a person, Process,or system that leads to information flow between object.

Ex, Users

Operation:- An active process stimulated by a subject.

Ex, Users send information to servers

Permission:- An approved to execute some action on the system. In most computer security literature, permission denotes some arrangement of object and operation.

Ex, Data access permission for Users.

Access control matrix:- A MATRIX in which each row denotes a subject, each column denotes an object, and each record is the set of access rights for that subject to that object.
Separation of Duty:- The norm that no user should be given abundant privileges such that they might misuse that system.

Ex, the rules for authorised and unauthorised users.

Safety:- Arrangements in place to ensure that the access control confirmation.

Ex, access control mechanisn or model.

Inbound:- If the access list is inbound, when a packed is delivered to the Router, the Cisco ISO check the standards statements of the access list for a match. If the packet is permissible, the software continues processing the packet. If the packet is denied, the software discards the packet.
Outbound:- If the access list is outbound, when the software receives and Router a packet to the departing interface, the Cisco ISO check the standards statements of the access list for a match. If the packet is permissible, the Cisco ISO transmits the packet. If the packet is denied, the software permissible discards the packet

Extended Access lists :– with extended access lists, you can be more precise in your filtering. You can evaluate source and destination IP addresses, type of layer 3 protocol, source and destination port… Extended access lists are harder to configure and require more processor time than the standard access lists, but they allow a much more granular level of control.

To demonstrate the concept, we will use the following example.

We have used the standard access list to prevent all users to access server S1. But, with that configuration, we have also disable access to S2! To be more specific, we can use extended access lists. Let’s say that we need to prevent users from accessing server S1. We could place an extended access list on R1 to prevent users from accessing S1. That way, no other traffic is forbidden, and users can still access the other server, S2:

Standard access lists – with standard access lists, you can filter only on the source IP address of a packet. These types of access list are not as powerful as extended access lists, but they are less processor intensive for the router.

The following example describes the way in which standard access lists can be used.

Let’s say that server S1 holds some important documents that need to be available only to company’s management. We could configure an access list on R1 to enable access to S1 only to users from the management network. All other traffic going to S1 will be blocked. This way, we can ensure that only authorized user can access sensitive files on S1.
