A Distributed Denial Of Service Attack And Defense Essay

This type of attack is any event that diminishes or eliminates a network’s capacity to perform its expected function. These attacks are launched against server resources

The most common type of DOS attack is ending traffic to a network address. This will cause the network to slow down. The attacker must already know a weakness of some sort on the network, or the attacker just goes

The messages sent out on Twitter by Payne on December 2, 2014, contained a link for a Distributed Denial of Service (DDoS) attack on the SLCPA website. The distributed (DDoS) was an attempt to make a machine or network resource inaccessible to its intended users. Networks have a limited amount of connections at any given time. The defendant exploited this limit by initiating as many connections with SLCPA website,

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.

It is not clear in the article if iPremier did any risk assessment, and if they did, they didn’t anticipate that they could be victims of a DDoS attack. iPremier should have used a Contingency Planning standard like NIST SP 800-34 to identify risks and develop policies and procedures to deal with attacks like the one they faced. If they had these, they could have responded in a more orderly and affectively fashion and they could have alternatives to overcome the negative impact

Denial-of-Service attack (DoS) when a hacker continuously attacks a particular network or dedicated Access Point (AP) with fake requests, failure messages and premature successful connection messages and other commands. These causes authorized users from preventing connecting to the network and results in network failure or crash. These attacks depends on misuse of protocols like Extensible Authentication Protocol (EAP).

DNS is critical in the footprinting of a target network. It can sometimes save the attacker a lot of time, or at least corroborate other information that has been gathered. DNS is also a target for several types of attack.

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

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.

tackers. For example, an attacker might want to get control of an IRC channel via

Alternative type of attack is called a Distributed Denial of Service (DDoS) attack. DDoS attacks are launched form numerous linked devices that are spread across the Internet. They are commonly harder to deflect, because of their sheer volume of devices involved. Unlike DoS attacks, DDoS assaults be apt to target the system infrastructure in an effort to drench it with huge volumes of traffic.

Abstract─Distantly controlled and managed (by botmaster or botherder) malicious software (called botnets or ‘bot armies’) hidden in large number of computers may cause extraordinary likely damage to the Internet. Botnets can initiate massive coordinated attacks upon Internet resources and its infrastructure devices. The most likely potential uses of botnets are distributed denial of service (DDoS) attacks, spamming, sniffing traffic, keylogging, installing advertisement addons and google adsense abuse, attacking internet relay chat (IRC) networks, attacking peer-to-peer (P2P) networks, hypertext transport protocol (HTTP) networks, and mass identity theft etc. This research is intended to review and analyze all aspects of well known botnets

Denial-of-service is an attack aimed to refuse access for legitimate users and disrupt service availability according to www.msdn.microsoft.com. This type of security threat according to www.tech.co.uk is rapidly increasing on the Internet due to open doors on Websites. By using the Internet, companies increase the risk of denial of service attack. Denial of service can also be caused by too many connected to a server at the same making run slow or unavailable to others. People who deliberately abuse a network server are often difficult to track down.

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.
