Denial of service attacks is common in businesses and organizational websites. Perpetrators of these attacks target services or sites that are hosted by high profile servers. These include credit card payment systems, banks and root name servers. The article on denial of service attacks that will be used is Dave Neal’s “Denial of Service Attacks Exploits White House Press Machine”. This article was published in The Inquirer on November 12, 2014.
According to this article, attackers used the White House press release machine as a way of gaining network trust. The White House made this discovery when it updated its internet report with a caution that attackers are exploiting the facility’s press release machine. These attackers are using content emanating from the White House to gain network trust. They are using DNS reflection attacks to exploit the press machine. Attackers who target the network at the White House are designing large DNS text records in order to increase amplification, and magnify their attacks. These attackers create their own text records to amplify the responses as required (Neal, 2014). This helps them to direct traffic to targeted sites. The targeted traffic, which is amplified overwhelms the targeted site and makes it unable to respond to requests. In this case, the attacks saturate the target network or machine with amplified external communication requests. These requests come in large numbers in order to prevent the machine from responding to legitimate traffic. They also cause the network or machine to respond slowly to legitimate traffic. Denial of service attacks eventually lead to server overload. This technique is effective because the text records have the ability to achieve the largest possible response. The attacks that were observed lasted for 5 hours and created a bandwidth load that peaked at 4.3Gbps (Neal, 2014). The text record technique has been extensively used to target entertainment ...

There are some users who create hurdles for others sometimes for fun purposes or to de-motivate users from working with a particular service or website. These people misuse the knowledge and worsen the reputation of certain organizations in the technological world.
This paper presents an overview of DoS attacks. This paper will discuss different types of DoS attacks. This paper will also outline the ways to deal with this threat. Denial of Service Attacks DoS attack (denial of service) can be defined as an event that prevents un-authorized access to the resources or make interruption in those operations that are critical with time factor.
The compromised zombie army is invaded by a Trojan, which is known as a remote application that installs itself within the system memory or kernel and provides data or connectivity to the hacker. Moreover, Trojan is operational by initiating an Internet Relay Chat (IRC) that waits for any action from the hacker who has full control over the botnet (Rapoza, 2008).
Denial of Service Attacks (DoSs)
One of the most well-known web server security attacks is known as a buffer overflow. Basically, a buffer overflow takes place when a software application attempts to store more data in a static buffer than its capacity to store or manage.
This is not to say that there are no preventive measures but the preventive measures do not undermine the potency of DoS attacks.
Quite simply a denial-of-service attack attempts to make computer resources unavailable to its intended users. DoS attacks are usually targeted at major websites or services hosted on high-profile web servers such as banks, credit card payment gateways or even DNS root servers.
The main goal of Denial of Service or DOS attack is to deny valid Internet and Network users from the services of the target system or Network or server. It launches an attack that prevents the use of services that are offered to the legitimate and authenticated users by the Network.
Large number of consumer use devices such as microwave ovens, baby monitors, and cordless phones operate on the unregulated 2.4GHz radio frequency. An attacker takes advantage of this and unleash large amount of noise by using these devices and jam the airwaves so that the
