Essays on DDOS

ABSTRACT

Cloud computing employs the use of parallel and highly computed processors to virtually and remotely deliver services. This is an important factor forenterprises whose processing resources are limited and who suffer limitations on the manpower and data storage. This notwithstanding, cloud computing faces a serious threat in the area of data security. This is because the attackers have become very opportunistic and look for any slight loophole that will enable them to bypass the server securities within the cloud computing environment. It is thus important to come up with a systematic approach that can help in identifying the vulnerabilities ...

Information Security Threats

Introduction Information is one of the most important assets for many organizations, as it acts as a differentiator and provides a competitive advantage. Loss of information such as patent information, proprietary processes, or trade secrets could prove to be very detrimental to a business. While there are many threats to the information security, this report focuses on three of them, which are 1) Denial of service, 2) Privilege escalation, and 3) Backdoor. This report provides measures that address, block, or removes these threats. Information about tools, products, or services that mitigate these threats is provided in the report as ...

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 ...

The three potential threats that may affect the network configuration are:

This type of attack is a group of compromised systems (also known as "zombie computers") that attack a single target to cause a denial of service to users themselves are legitimate. The attack consists of a huge flow of messages and requests to the target network. The information flow is released for this overloading and force the system to shut down; as a result, it denies service to legitimate users. A typical way ...

Abstract

Web servers are the building blocks of this generation distributed systems and plays a major role in the enterprise application architectures. Due to the flexibility and openness that these Web server centric computing model offers, though makes this ubiquity possible, it also opens up corporate data and processes to security threats. This paper focuses on the security of the public Web servers. There are many different vulnerabilities such as exploits utilizing software bugs in the underlying operating system, denial of service, unauthorized access of confidential information, man-in-the middle attacks, subvert the Web server and use it as a bot ...

Mitigation of cyber attacks

Introduction The development of internet technology has both advantages and limitations on global development. The major drawback associated with advancement in internet technology is the cyber crime, which is globally on a rise (Weimann, 2006). Cyber terrorism poses serious threats to the security of both private companies and government institutions. Cyber attacks involve unauthorized access to critical information as well as the infrastructure of business organizations and public institutions (Weimann, 2006). The resultant effects of cyber attacks are numerous, and they make both private and public entities more vulnerable to collapse (Osipenko, 2004, p 46). Thus, these institutions adopt ...

Introduction

The question that comes to mind is what is Trojan horse? Trojan horse is stated to be a malicious program that looks harmless however, it is used to hack into people’s computers. The term Trojan horse is derived from Trojan War a Greek mythology (Christensson, 2006). The myth talks about the wooden horse that was pulled by the people from Troy. The legend claims that inside the horse there were Greek soldiers in it who emerged at night and seized the city. This fact can be observed from the program where a person installs the application unaware that ...

It is an accepted fact nowadays that our current society is largely dependent on cyber technologies. Majority of people store their personal files and information online, do transactions over the Internet, and use the World Wide Web as one of their primary forms of communication. Aside from people, many companies and economies are powered by the internet. Thus, it can be said that the internet is an indispensable part of today’s society. Despite this fact, the World Wide Web is still largely unprotected due to its status as a free and autonomous system, free from any governing bodies ...

While it is hard to determine the links between these actors, as they are ...

Section 1: Foundation of the Study

The majority of business information is stored electronically, creating the need for a system of securing this information. As the systems providing computer and internet security becomes more and more complex, security is increasingly compromised. Interlopers and hackers continue to create new and more creative means of gaining entry to information stored on networks, and users are facing an increased number of security attacks. Surprisingly, despite the variety and amount of security risks, security tools designed to counter these are slow to develop appear for business consumption (Garcia-Teodoro et al, 2009). With the introduction of new technological trends, information technology ( ...

Introduction

While information warfare has been around since the first armies discovered the importance of gathering and using information to gain an advantage over an opponent, its incorporation of cyberterrorism methods is a completely new development. The basic model consists of an attack against an opponent’s information infrastructure, such as a computer network, to intimidate or threaten in furtherance of a political or social objective. Ostensibly, the attack is committed by a terrorist group of their own accord but the reality is that the group is sponsored, equipped or otherwise assisted by a nation-state who cannot directly initiate the attack due to legal or ...

DoS and DDoS attacks A Denial-of-Service (DoS) attack is an attack intended to close down a computer or network by making it unreachable to its intentional users. These attacks have achieved by spilling over the aimed computer or network with traffic, or with distribution of information that activates a crash. In both cases, the DoS attack restricts legitimate users to use the service and computer. There are two common ways of DoS attacks that are flooding services and crashing services. Flooding means, the system receives excessive amount of traffic for the server to buffer that cause system to slow down and ...

Introduction

According to a survey given earlier this year leaders from the U.S. Department of Defense as members of Congress that cyberterrorism posed one of the major threats to U.S. interests. The survey echoes the sentiments of FBI director Robert Mueller when he stated in cyber terrorism may be a bigger threat than conventional terrorism. But with so many high level officials claiming the dangerousness of cyberterrorism, should the public be equally wary? What exactly are the dangers of a cyberterrorist attack? Moreover, if that attack were to ever come, what would its impact be on the U.S. and what measure could we ...

Google has developed self-driving cars. Although the cars are not yet fully developed, they have been tested on the roads. The cars are manned by operators who understand how the technology works. The cars have been developed to make use of cameras, sensors that use sensor technology and laser range finders so that they are able to navigate the traffic. They have also been developed to make use of maps which are detailed. This way, they are able to know the traffic and the road that has been set ahead. This is enhanced and made possible with the well-developed ...

Intrusion detection and prevention systems are the most reliable form of securing APT incidences and the overall security of the information infrastructure. This is because, unlike susceptibility and management systems and IT infrastructure support, they have the capacity to detect occurrences of APT and subsequently prevent damage to the computer systems. Firewalls are supposed to block illicit impound traffic, but in most instances, they do not succeed. Intrusion detection and prevention systems have the capability to detect and catch threats missed by the firewalls. Susceptibility management systems are used to identify, remediate and mitigate vulnerabilities in computer networks but ...

Attackers are becoming more and more sophisticated and utilize highly sophisticated techniques to compromise critical information infrastructure that supports networks and information flow. In order for attacks to be successful, attackers are devising new mechanisms of promoting anonymity and evading detection. - Promoting anonymity Network attacks are classified into interactive attacks where perpetrator is concerned with stealing information from another user of the network or non-interactive where a perpetrator uses malicious software to instill denial of service attacks on other members of the network.

The two most common methods of used by attackers include,

- Stepping stones chains - IP-spoofing - Stepping stone chains Stepping ...

Given the current state of computer security, Vulnerability assessment is required to ascertain the state of the system. VA determines the security situation in a system and give recommendations. This process can be done through penetration testing and vulnerability scanning. Penetration scanning takes care of the networks ports that are susceptible to attacks. Vulnerability scanning, on the other hand, is directed to the susceptible hosts and applications, therefore, protecting the system. First principles Vulnerability Assessment have four phases that include Architectural analysis, Resource Analysis, Privilege Analysis and Component Analysis. It is true that Architectural analysis probes the contents of ...

Introduction

CHAPTER 1

INTRODUCTION

Denial of Service (DoS) attacks is an endeavor to make computer resources unavailable to the legitimate users. A DoS attack will try to consume as much resources as it can so as to deny legitimate users the chance of having services or resources available to them. There are several categories of DoS attacks. The DoS attacks are not the same in terms of how they are perpetrated. Depending on the method of perpetration, one category of DoS can be easy or hard to stop. 1 A denial of service attack involves sending numerous communication requests to the ...
