Question

Protecting information resources as well as data communication delivery is one of the greatest concerns for information systems managers. Information can be delivered anywhere and anytime. Some common threats to resources and delivery are rogue access points, DOS attacks, social engineering, viruses, worms and phishing.  As an information systems manager, you will want to address these issues and maintain control providing rapid responses as often as needed. One avenue is to use CERT teams, implement fault tolerance, password strategies, encryption measures and many others discussed in the text.

Please post your initial response with no less than 250 words

What types of networks have you used? What are some experiences you have had concerning the common threats listed above? How does a network topology affect data communication? Your discussion(s) should be addressed from a managers perspective as well as personal experiences.

Explanation / Answer

There are such a variety of various sorts of PC systems in presence, it can be difficult to comprehend the contrasts between them, especially the ones with fundamentally the same as sounding names. This lesson clarifies the structures and elements of the absolute most mainstream PC systems.

Sorts of Networks

There are a few unique sorts of PC systems. PC systems can be portrayed by their size and also their motivation.

The extent of a system can be communicated by the geographic territory they possess and the quantity of PCs that are a piece of the system. Systems can cover anything from a modest bunch of gadgets inside a solitary space to a large number of gadgets spread over the whole globe.

A portion of the diverse systems in light of size are:

As far as reason, many systems can be viewed as broadly useful, which implies they are utilized for everything from sending records to a printer to getting to the Internet. A few sorts of systems, be that as it may, fill an exceptionally specific need. A portion of the distinctive systems in view of their fundamental reason for existing are:

We should take a gander at each of these in more fine grained detail.

Personal Area Network

An individual range system, or PAN, is a PC arrange sorted out around a distinct individual inside a solitary building. This could be inside a little office or living arrangement. A normal PAN would incorporate at least one PCs, phones, fringe gadgets, computer game consoles and other individual stimulation gadgets.

On the off chance that numerous people utilize a similar system inside a home, the system is once in a while alluded to as a home territory system, or HAN. In an extremely regular setup, a living arrangement will have a solitary wired Internet association associated with a modem. This modem then gives both wired and remote associations for different gadgets. The system is commonly overseen from a solitary PC however can be gotten to from any gadget.

This kind of system gives awesome adaptability. For instance, it permits you to:

Send an archive to the printer in the workplace upstairs while you are perched on the love seat with your tablet.

Transfer a photograph from your wireless to your desktop PC.

Watch motion pictures from a web based spilling administration to your TV.

In the event that this sounds well known to you, you likely have a PAN in your home without having called it by its name.

Local Area Network

A LAN, comprises of a PC organize at a solitary site, commonly an individual office building. A LAN is extremely helpful for sharing assets, for example, information stockpiling and printers. LANs can be worked with moderately modest equipment, for example, center points, arrange connectors and Ethernet links.

The littlest LAN may just utilize two PCs, while bigger LANs can suit a huge number of PCs. A LAN commonly depends for the most part on wired associations for expanded speed and security, yet remote associations can likewise be a piece of a LAN. Fast and moderately ease are the characterizing qualities of LANs.

LANs are ordinarily utilized for single locales where individuals need to impart assets among themselves however not to whatever is left of the outside world. Think about an office building where everyone ought to have the capacity to get to records on a focal server or have the capacity to print an archive to at least one focal printers. Those assignments ought to be simple for everyone working in a similar office, however you would not need someone simply strolling outside to have the capacity to send a report to the printer from their mobile phone! On the off chance that a neighborhood, or LAN, is altogether remote, it is alluded to as a remote neighborhood, or WLAN.

Metropolitan Area Network

A metropolitan range system, or MAN, comprises of a PC arrange over a whole city, school grounds or little area. A MAN is bigger than a LAN, which is normally constrained to a solitary building or site. Contingent upon the setup, this sort of system can cover a range from a few miles to many miles. A MAN is regularly used to associate a few LANs together to shape a greater system. At the point when this sort of system is particularly intended for a school grounds, it is once in a while alluded to as a grounds territory arrange, or CAN.

Wide Area Network

A wide range system, or WAN, possesses a substantial region, for example, a whole nation or the whole world. A WAN can contain various littler systems, for example, LANs or MANs. The Internet is the best-known case of an open WAN.

DoS attack:-

A DoS attack is a cyber attack that uses large network and huge volumes of traffic to overwhelm a server or network, slowing it or rendering it completely unresponsive.

DoS attacks require that the attacker control thousands, tens of thousands or hundreds of thousands of computers – usually owned by normal, unsuspecting consumers all over the world – and create their own network out of these “zombie computers.”

Four types of DoS attackes:

Flooding: A flooding attack sends a large amount of traffic to a victim network to congest the network with traffic.

Amplification Attack: manipulates publicly-accessible domain name systems, making them flood a target with large quantities of UDP (user datagram protocol) packets.

Resource Depletion Attack: floods the victim server with bogus information packets to seize up the server, so it cannot respond to legitimate requests for information.

Diversion or Ransom Attack: the attacker commences a DoS act against victim server to distract the security team and incident responders while the attacker uses different methods to penetrate the network.

DEFENDING AGAINST DOS ATTACKS

Though it’s not always possible to defend against a large, organized DoS attack without some impact to the targeted network, there are strategies that can help mitigate the effects of even the most vicious DoS attacks:

Recognize the signs of a DoS attack: the best defense against a DoS attack is to recognize it early. Not all DoS attacks are easy to identify from normal spikes in network or web traffic, or a sudden slowdown in network performance. Invest in the right technology, expertise.

include in it a DoS mitigation plan.

Network Topology:-

A Network topology is the plan of a system, including its hubs and interfacing lines. There are two methods for characterizing system geometry: the physical topology and the legitimate (or flag) topology.

In the bus topology, each workstation is associated with a principle link called the transport. In this manner, as a result, every workstation is straightforwardly associated with each other workstation in the system.

In the star organize topology, there is a focal PC or server to which every one of the workstations are specifically associated. Each workstation is in a roundabout way associated with each other through the focal PC.

In the ring system topology, the workstations are associated in a shut circle design. Contiguous sets of workstations are straightforwardly associated. Different sets of workstations are by implication associated, the information going through at least one middle of the road hubs.

In the Token Ring topology is utilized as a part of a star or ring topology, the flag goes in just a single course, conveyed by a supposed token from hub to hub.

The mesh topology utilizes both of two plans, called full work and fractional work. In the full work topology, every workstation is associated straightforwardly to each of the others. In the halfway work topology, a few workstations are associated with all the others, and some are associated just to those different hubs with which they trade the most information.

The tree topology utilizes at least two star systems associated together. The focal PCs of the star systems are associated with a fundamental transport. Hence, a tree system is a transport system of star systems.
