Essays on Network Traffic

Part 1

DoS and DDoS attacks have evolved over the years to become targeted attacks involving extortion and other crimes. DoS and DDos are no longer simple botnets; they are systems with sophistication (Reiher & Mirkovic, 2004). The attacks have grown to reach super-sized volumes of more than 500Mbps bandwidth. The attacks have become more flexible; recent attacks use scripts for traffic randomization. Others mimic Google bots to avoid stringent web filters. Reflection and amplification allow attackers to achieve more damage with little. Large corporations are exposed to dangers of losing their assets because of DoS and DDoS attacks. They can lose ...

Intrusion Detection Systems

Different techniques abound for monitoring computer networks especially within the context of providing security for the network. Intrusion detection is one of such techniques used for security management of computers by analyzing and gathering information from the different areas of a computer network with the aim of identifying possible breaches in the security of the network (Allen et al., 2000). A system put in place to implement any of these techniques is referred to as an intrusion detection system. For the computer network of an organization, the source of breaches to the network can be from within the organization ...

Abstract:

The modern world is an interconnected world. Electronic devices have been connected with each other, which allow sharing of data. Underlying the interconnected world are numerous networks of computers that together make up the internet. However, the rise of the internet has also brought about serious security risks. Using these connections, data can be transmitted to any device on the network. This means that people have numerous opportunities to intercept communication or initiate their own communications. This makes it easy to send malicious software that can be used to steal data or corrupt computer systems. In order to prevent ...

Definition of the business technical problem

This document is aimed at providing the Chief Information Officer with high-level information for establishing a network management architecture which will provide UMUC with a high-reliable network and support infrastructure. Ullman, Manly & Ulysses Corporation has been relying on its network as well as outsourcing network infrastructure for its business operations. UMUC is faced with unreliable network infrastructure that keeps failing thus interrupting the firm’s operations.

Problem within the context

However, over the years, its exponential growth has overwhelmed the telecommunication capabilities of its network infrastructure, and the third party that was recruited to provide network infrastructure has not been able to keep ...

Possible infrastructure vulnerabilities:

A computer network is made up of two or more electronic media that are able to communicate with each other through a predetermined way. Computer networks are very important to the world at present. Network vulnerabilities can be described as any security exposure that exposes the network to undesirable activity or unauthorized access. Network vulnerability has the possibility to lead to unauthorized access to information and resources of the network, altering the activities of the networks and even to the total denial of the network (EC-Council Press, 2011). Network vulnerabilities can be categorized into two main categories; application or ...

ISP REMOTE:

ISP REMOTE INTRODUCTION ISP is an acronym for Internet service provider. The term is used to describe a company that can provide one with the ability to access the internet. The ISP provides a gateway to the large interconnected pool of computers that a make up the worldwide web. The connection to the internet can be achieved through different approaches (Fonseca, M. and Agoulmine, N., 2015. p.n.d).These approaches include: Dial-up services: this is a service that provides connectivity to the Internet through the use of the telephony network. It works by connecting the telephone line to the computer ...

It is true that the TCP protocol is the most used protocol for data transfer in the world. It’s more reliable and easy to implement. Furthermore, its ability to control the congestion of flow of data makes it a popular protocol. It would be ideal to give an insight as to how the TCP manages or controls the flow of data, with this then we can clearly understand the congestion control mechanism. TCP has inbuilt mechanisms for controlling the flow of data between the sender and the receiver. TCP flow control allows the receiver to broadcast the amount of ...
