Denial Of Service Attack

iPremier, a Seattle based company, was founded in 1996 by two students from Swathmore College. iPremier had become one of a few success web-based commerce, selling luxury, rare, and vintage goods over the Internet. Most of iPremier’s goods sell between fifty and a few hundred dollars, and the customer buys the products online with his or her credit card. iPremier’s competitive advantage is their flexible return policies which allows the customer to thoroughly check out the product and make a decision to keep the product or return it. The majority of iPremier customers are high end, and credit limits are not a problem.

Denial of service – Denial of service or DOS is an attempt to make a machine or network unavailable to its users. The services that were available to the user wouldn’t be available anymore. Although the result of a DOS attack does not lead to data theft. However a great deal of time and money can cost the company. An example of a service being stopped is email, or can be a loss of network connectivity. There could be no access to shared storage and no one would be able to access the internet while the DOS attack.

This presentation discusses an incident known as a denial of service (DoS) as well as an intrusion of the clinic’s network systems. A denial of service (DoS) attack is designed to shut down services which a business needs to operate. This incident caused widespread slowness and outages to internet services and affected the clinic’s capability to properly treat its patients. In this presentation, the incident is examined. The processes to detect, analyze, contain, eradicate and recover from the incident are the focus of the presentation. Once the incident investigation was complete, special consideration was made as to what was learned and how clinic staff can help protect the clinic’s ability to properly serve its patients.

The exponential increase use of the Internet to communicate, conduct business transactions, access personal banking, healthcare, education at confront of being anywhere has become an everyday lifestyle for many people around the globe. This reliance on computers, laptops, devices and other Internet of Things to access the Internet means, organizations, businesses and the government have also seen an increase occurrence of sophisticated attacks.

Imagine that you get home from a hard day at work or school, have a bite to eat, and then sit at your computer. After you've checked your e-mail, you're ready to play an online game. Excitement begins to build, but then you notice your browser was denied access to your network, preventing you from connecting to the Internet. In desperation, you turn your computer's power off and restart it. After the reboot, your computer still cannot reach any networked service. Since only your computer was involved, you think it may be a Denial of Service attack. However, days later you learn that the attack you experienced was a Distributed Denial of Service, an attack involving numerous computers that flooded the game servers and prevented anyone from gaining

(Samuel Folledo) How many of us know exactly what Denial-of-Service attacks is? Aside from how powerful and easy it is to perform these attacks, its mysteriousness alone illustrates a huge danger in the computer world. A deep understanding of DoS can save a lot of headaches as these cybercriminals are able to steal from personal informations to bringing down sites and companies. The first wall of prevention against these attacks is always awareness. This is why being knowledgeable on Denial-of-Service attacks important. (End of Intro)

A DoS Attack, or Denial-of-Service attack, is an attack that that fill a network with lots of useless traffic. Many DoS attacks, such as the Ping of Death and Teardrop attacks, exploit limitations in the TCP/IP protocols. A couple of the most recent DoS attacks have been directed to Capitol One and SunTrust Banks. In October Capital One and SunTrust were attacked by this Denial-of-Service. Capital One’s website was inaccessible for 8 hours because the network was just filled with useless traffic. In the next couple of days SunTrust bank suffered performance issues.

One reason for DDoS attacks is it is a form of protest by disgruntled fans and workers. Another reason for this attack is because the game industry is not up to date with security measures and that makes it very vulnerable to attacks. The effects of a DDoS attack can be severe for the company they are likely to lose a lot of revenue and their reputation goes at down the drain (Saeed, 2015). Both of these have a huge potential of dampening their potential growth for the company.

As the term was used more frequently, I started to learn that this concept was real and frankly frightening. A DDOS attack meant a distributed denial of service attack, causing one’s Minecraft character to disconnect from the server and drop everything they had for the other players to steal. The fact that someone could use the machine I do homework on to impact another person’s computer was fascinating to me. I asked about the DDOS attack and was told that one can “resolve” someone’s “IP” from their Skype name and use a “botnet” to take out their Wi-Fi. I figured this idea was too complicated to be true, so I ignored it and continued to play. Until one day I conflicted with the wrong person and spent the next 30 minutes without Wi-Fi. After that, I spent many hours researching how this was possible. I watched videos, read blogs, and joined many forums, trying to get a grasp on the topic. My goal: to never have my system compromised again. Through all my hard work, I became famous on the Minecraft server because no matter how agitated people became, they were not able to find my IP. I made it my business to help every player have the same protection, soon helping more than 20 people. From that point on, cyber-security became my passion. I am still blown away by everything a computer can do.

Denial of Service (DoS) attack is a very common cyber menace that renders websites and other online means inaccessible to intended users. There are various types of DoS threats and nearly all directly target the core server structure. Others abuse weaknesses in application and communication proprieties. DoS is also used as a cover-up for other wicked actions, and to take down security applications like web firewalls. A prosperous DoS attack is very obvious and impacts the entire online user base.

These attacks usually put a heavy load on the target by making regular requests very rapidly. It is hard to distinguish if a web server is stormed by thousands of clients, or if there is a DoS attack in progress. A simple way to force the problem of heavy load is to use a server farm together with a load balancer. This will help against small attacks, but not against a DDoS started from several hundred hosts. Furthermore, increasing the number of servers is rather expensive.

Every day in the Information Technology industry there is an attack that can be so devastating as to completely shut down websites, webservers or even possible someone’s ISP or internet service provider. It is called DDOS or Distributed Denial of Service, it’s a simplistic attack for the most part and just requires moderate resources to accomplish. The attacker hires or creates a botnet and then targets a specific IP and port and then begins to

In Denial of Service access to network applications or data is denied to intended users. Denial of Service may be invoked through many techniques. The most common technique is overload of server resources such as memory and CPU by flooding the network with database queries that ultimately cause the server to crash

Distributed denial of service is hard to block. Due to much traffic, system could not tolerate the unacceptable requests from different machines. A single user is attacked from the number of attackers. The millions of requests force the computer to shut down. The main purpose of denial of service is to disturb business of specific organization. The normal work is effected such as make server unavailable to its regular users. A single blockage of an IP address could not stop the attack.

Due to reliance on the Internet to conduct business, DDoS present a concern for Connect Groups networks. Stats show UK is second after the US in DDoS attacks at 10.21%. DDoS attacks are an attempt to make an online unavailable by overwhelming it with traffic from multiple sources. They target a wide industry from banks to news websites, and present a major challenge to make sure people can publish and access important information.
